Land Rover Discovery 4, 2010

The new, fourth generation of Land Rover's supremely versatile seven-seat vehicle gains a new name - Land Rover Discovery 4 - to go with its powerful and highly efficient new TDV6 diesel engine, fresh exterior identity and more premium cabin. The class-leading breadth of capability is extended even further with dynamic improvements for both road and off-road driving, and Land Rover has added a battery of user-friendly new technologies and features.

Star billing on the Land Rover Discovery 4 goes to the highly efficient and refined new LR-TDV6 3.0 twin turbo diesel engine. This delivers a 9 percent fuel economy improvement (EU combined cycle) and ten percent less CO2 emissions, at the same time as increasing power by 29%, all compared with the existing 2.7-litre engine. Torque increases even more, up 36% to 600Nm - believed to be the highest torque output of any 6-cylinder, production diesel, passenger vehicle engine in the world.

The power and torque are both accessible across the entire rev range, to deliver immediate throttle response and effortless cruising ability. The results include a 0-60mph time of 9.0 seconds, (0-100 km/h in 9.6 seconds), a 24 percent improvement over the 2.7-litre.
Land Rover's engineers have also transformed the on-road ride and handling for the new generation Land Rover Discovery 4, and even improved on the near-legendary off-road capabilities of its predecessor. The comprehensive changes include new suspension components, revised steering, larger brakes, improved traction control, and enhancements to the award winning Terrain ResponseTM system, which helps optimise the vehicle for virtually all on-road or off-road driving situations.

The iconic exterior design has been updated, most obviously with smoother and simpler surfaces at the front, including a new, more aerodynamic bumper. The sportier new lights help give the vehicle new character, and include LED technology front and rear. The sophisticated new front headlights include High Beam Assist, switching on or off, as conditions require.

The interior is completely redesigned, with a transformed dash and centre console, new seats and an array of new, user friendly features.

New features available for the Land Rover Discovery 4 include a Portable Audio Interface, DAB radio, a new five-camera 'surround' system, for easier parking and towing, and a new key system which offers Keyless Entry and Push Button Start.

e-Terrain technologies boost economy and lower CO2 emissions
The new Discovery is packed with features aimed at reducing fuel consumption and reducing CO2 emissions. The new LR-TDV6 3.0 Sequential Turbo Diesel engine was designed from the outset to deliver class-leading fuel economy and improved low-end torque.

The parallel sequential turbocharging system of the 3.0-litre diesel makes use of its larger, primary turbo most of the time. The smaller secondary turbo remains dormant when higher power is not required, reducing pumping losses and consequently, fuel consumption. A highly efficient, third generation common rail injection system with piezo injectors and fuel metering, also makes a substantial contribution to fuel economy.

The new engine has been also been optimised for low-end torque as well as economy, making it possible to activate the lock-up clutch of the ZF HP-28 automatic transmission at lower speed. This reduces 'slip' in the hydraulic torque converter improving both fuel consumption and CO2 emissions. The higher torque at lower rpm also enables longer gearing for more economical cruising.

The Discovery incorporates several other energy saving features too. At standstill, the idle speed of the V6 has been reduced from 750rpm to 710rpm, giving a fuel saving without compromising refinement. An Intelligent Power Management System includes Smart Regenerative Charging, so whenever possible the alternator charges the battery when it is most economical to do so, such as when the car is coasting rather than accelerating.

Aerodynamic changes to the front end, with the revised front lower chin spoiler and new front wheel deflectors, help to reduce drag by increasing underfloor airflow.
The new air conditioning pump is driven through a clutch which disengages when the air conditioning is not in use reducing parasitic losses and delivering improvements in fuel consumption and CO2 emissions.

At the heart of the improvements introduced with Land Rover Discovery 4 is an exceptional and highly efficient new diesel engine. The LR-TDV6 3.0 sequential turbodiesel is based on the existing LR-TDV6 2.7-litre engine, but radically redesigned to deliver substantially higher performance, lower emissions and better fuel economy.

The 2.7-litre has won many admirers as one of the most refined diesels ever made. The new, twin turbocharger LR-TDV6 3.0 boasts substantial increases in both power - up 29 percent to 245PS - and torque, up 36 percent to 600Nm. The ability to deliver maximum torque at just 2,000rpm, combined with unparalleled throttle response, substantially enhances the Discovery's already acclaimed ability both on and off-road.

The new 3.0-litre diesel can significantly out perform its rivals by delivering 500Nm in only 500 milliseconds from idle. From the driver's perspective this means instantaneous access to 83 percent of maximum torque.

But despite this extra performance, engine emissions are dramatically reduced. When fitted with DPF, the new LR-TDV6 3.0 meets EU5 emissions requirements (not due to come into force until 2011) and with a CO2 figure of 244g/km, it undercuts the existing 2.7-litre automatic by ten percent. Fuel economy is also improved by 9 percent, delivering 30.4mpg (9.3 l/100km) on the EU Combined cycle.

The new 3.0-litre engine has been developed by a joint Jaguar Land Rover team, with base characteristics designed from the outset with the requirements of both brands in mind. High levels of torque and fast response from low revs perfectly suits both Jaguar and Land Rover DNA. The Jaguar version, the AJ-V6D Gen III S, was recently launched in the new Jaguar XF.

The LR-TDV6 engine has a deeper sump than its Jaguar sibling, to ensure the efficiency of the lubrication system is not compromised when venturing off-road. The oil scavenge system of the turbochargers has been enhanced for a similar reason, ensuring no oil collects in the turbochargers at extreme angles in off-road conditions.

For the Land Rover version, belt drives are waterproofed, as are the alternator, air conditioning compressor, power steering pump and starter motor. The engine is also tuned specifically to allow for the greater demands made on the Land Rover Discovery 4, particularly for towing and all-terrain driving.

Twin-turbos - immensely efficient, highly responsive
A key feature of the new LR-TDV6 3.0 is the unique, parallel sequential turbocharger system, the first of its type to be fitted to a V-engine anywhere in the world. Delivering high torque throughout the entire engine-rev range, improved throttle response and low CO2 emissions, the twin-turbochargers work sequentially to provide unrivalled response and best-in-class torque at low engine speeds, while also packing a huge punch at higher speeds.

Driving a turbocharger requires pressure from the exhaust, creating pumping losses in the engine and increasing fuel consumption. Under the control of the engine management system, valves isolate the secondary turbocharger both from the exhaust stream and the engine inlet tract when it is not required. A balance pipe connecting the two manifolds allows the gas from both manifolds to feed through the primary turbocharger.

The new 3.0-litre diesel can significantly out perform its rivals by delivering 500Nm in only 500 milliseconds from idle, unlike many diesels which can suffer turbo-lag at very low revs. From the driver's perspective this means instantaneous access to 84 percent of maximum torque.

Third generation common rail
A new common rail fuel-injection system delivers up to five injections on each cycle at a pressure of 2000bar. Each injector tip is perforated by seven holes through which finely atomised fuel is sprayed into the cylinders. The high-pressure injection increases power, improves economy and reduces both CO2 and particulate emissions. New, high-speed piezo injectors are designed to keep injection noise to a minimum.

Piezo crystal 'packs' operate each injector by expanding when an electric current is passed through them. They react virtually instantaneously but make a distinctive click when fired, which can add to diesel engine noise at idle. The crystals in Land Rover's new injectors are fitted nearer the tip meaning they are mounted deeper inside the engine providing better sound insulation and quieter operation.

Also new to the third-generation fuel-injection system is 'metering mode'. Traditional diesel common rail fuel pumps oversupply the injectors, with the surplus being returned to the fuel tank. During this process, fuel temperature increases and cooling it again consumes considerable amounts of energy. In metering mode, the pump delivers fuel to the injectors only at the rate required. Consequentially, there is no rise in fuel temperature and no wasted energy.

Rugged yet lightweight
The two cylinder heads, with four valves per cylinder, are made from aluminium and the cylinder block is made from compact graphite iron (CGI) as before. The higher tensile strength of CGI makes it possible to cast a smaller block some 80mm shorter than a conventional 'grey' cast iron equivalent.

The new, water-cooled, exhaust gas recirculation system (EGR), important for reducing pumping losses and emissions of NOX in a diesel engine, is more efficient and consumes less power than its predecessor, with the valves allowing exhaust gas into the system being located on the 'hot side' of the engine nearest the exhaust manifolds. These valves never cool while the engine is running, so there is no condensation of combustion deposits which occurs on engines fitted with 'cold side' valves, hence the EGR system always works at maximum efficiency. Since the EGR cooling is so effective, exhaust gasses can bypass the system and return to the exhaust pipes, allowing faster engine warm-up from start-up and reducing emissions still further.

EU 5 emissions regulations have been achieved using conventional diesel oxidation catalysts and diesel particulate filters (DPFs). NOX levels are reduced sufficiently at source through the combustion system design, the addition of the new common rail injection system and the new EGR system with by-pass. As a result, specialised NOX exhaust after-treatment is unnecessary, avoiding a potential cost and the need to use additional precious metals in the exhaust system.

Increased refinement
The CGI cylinder block and new piezo injector design reduce combustion noise in the new engine. Multiple, precise injections of fuel on the combustion stroke also reduce combustion noise and all engine covers including camshaft covers, front covers and the sump have been optimised to subdue radiated noise.

The new diesel underwent analysis using the latest computer aided engineering techniques, followed by exhaustive rig testing. All the engine enclosures have been ribbed to minimise radiated noise.

Internal friction, a major contributor to unnecessary fuel consumption, has been addressed by careful optimisation of the crankshaft, valves and pistons. All these features combine to make the new LR-TDV6 3.0 Sequential Turbo Diesel one of the quietest premium diesels on the market today with increased service intervals of 16,000 miles.

Levels of refinement on the new LR-TDV6 engine are such that Land Rover's patented device for the diesel fuel filler neck, to reduce the risk of inadvertent fuelling with petrol, is fitted to the new Land Rover Discovery 4.

Responsive new transmission
The LR-TDV6 3.0 is mated to the revised and super-smooth ZF HP28 6-speed automatic transmission. Its characteristics have been optimised by Land Rover engineers to provide class-leading response, with rapid and refined shifts. The dramatic enhancement of both power and torque low down the rev range on the new engine have made it possible to actuate the transmission's lock-up clutches much earlier in each gear, reducing slip through the hydraulic torque converter, so helping with the improvements in both fuel consumption and CO2 emissions.

Dynamics transformed
Major dynamic advances introduced for the Land Rover Discovery 4 include revised suspension architecture, improved steering, larger brakes and enhanced versions of Land Rover's award-winning Terrain ResponseTM and Hill Descent Control systems.

The list of changes starts with new suspension knuckles, designed to reduce the separation between the suspension roll centre and the vehicle's centre of gravity (reduction of 42mm at the front and 62mm at the rear). This dramatically reduces the vehicle's natural body movements when cornering. These roll rates are further controlled by a stiffer and larger anti-roll bar.

In addition, new bushes and new front and rear dampers enhance ride quality.
The variable ratio steering rack is revised, complementing the improved ride quality by reducing 'twitchiness' around the centre line at high speed cruising and slightly increasing sensitivity at higher lock angles. This enhances the sense of driver involvement in high-speed manoeuvres, and also increases precision for low speed control and off-roading.
The redesigned front bumper also helps improve steering feel, as its new anti-drag lips help reduce aerodynamic lift at the front of the vehicle by up to 50% at higher speeds.

Increased stopping power
A new, larger brake system has been introduced along with the new engines, to cater for the Land Rover Discovery 4's enhanced performance and to improve braking feel.

This new system is derived from the four-piston, opposed-calliper performance system used on the Land Rover Range Rover Sport. It employs a 360mm ventilated front disc with a new, cast iron twin-piston sliding calliper - which serves to reduce the size of the front brake package while preserving its stiffness, which in turn helps achieve excellent pedal feel.

At the rear, a single piston sliding calliper operates on a 350mm ventilated disc, now manufactured in aluminium to help reduce vehicle weight.
An additional advance to the braking system is the new emergency brake light function. When the vehicle undertakes severe or emergency braking, the brake lights flash, to reduce the risk of rear end collisions.

More control in the bends
A refinement to the understeer control system helps automatically slow the vehicle if taking a bend too fast, enhancing driver control.

The system operates according to steering inputs from the driver. In extreme cases, automatic braking intervenes to reduce the vehicle speed, with the braking pressure level applied according to the steering inputs. Automatic braking up to 'emergency stop' may be applied, if the inputs demand.

Updates for award-winning Terrain ResponseTM and Hill Descent Control
For Discovery 4, Land Rover's award-winning Terrain ResponseTM system gains new features and refinements, further extending the vehicle's all-terrain capability. Terrain ResponseTM optimises the vehicle set-up for virtually all on-road or off-road driving situations, with five different settings to suit different terrains:
    * General driving
    * Grass/gravel/snow
    * Sand
    * Mud and ruts
    * Rock crawl

For soft sand - one of the most power-hungry surfaces - 'sand launch control' has now been introduced, which makes for noticeably easier drive-away. New, speed-dependent wheel-slip targets for the traction control system permit only very limited initial wheel-slip, helping to prevent the wheels digging down into the sand.

When picking a drive route through boulders, severe articulations can lead to the vehicle leaning in an undesirable direction, calling for simultaneous brake and accelerator engagement. New for Land Rover Discovery 4, revisions to the rock crawl program improve brake and traction control response times, helping to reduce the vehicle's tendency to roll when traversing boulders and giving a more composed drive through rocky terrain.

Land Rover's much-acclaimed Hill Descent Control system is enhanced on Land Rover Discovery 4 with the addition of Gradient Release Control. This inhibits the initial rate of acceleration when descending very steep inclines, to increase control and eliminate the potentially alarming lurch which can occur when braking is released at extreme angles.

The system operates automatically whenever Hill Descent Control is engaged, temporarily maintaining brake pressure after the driver releases the brake pedal. It then progressively eases braking pressure to control vehicle momentum and acceleration. Once the vehicle's target off-road speed is achieved, Hill Descent Control operates to take vehicle to the bottom of the slope in its customary composed manner.

A new face on a distinctive design
The Land Rover Discovery has evolved a distinct design heritage over 20 years and four generations of iconic, instantly recognisable vehicles. Land Rover Discovery 4 inherits the clean lines of the previous generation, but now subtly updated and given a more premium, more contemporary look.

Smoother, simpler surfaces are employed at the front, giving the vehicle its new character, emphasised by sportier looking front lights, with new LED position lamps configured in a unique, signature stepped profile around the main light units. New lights are also introduced at the rear of the vehicle, incorporating LED stop, tail and indicator technology.

The new front bumper has a larger cooling aperture to accommodate the new engine's greater power outputs. Cleverly, the larger bumper actually improves vehicle aerodynamics by reducing drag, thanks to its innovative anti-drag 'lips' that help smooth the airflow from the front bumper around the front wheels.

A new, twin seven-spoke 19" wheel design is introduced on the Land Rover Discovery 4 to complement the existing 7-spoke 19" wheel and, for the first time, a new striking, 10-spoke 20" wheel is available as a factory-fit option.

Three new paint colours complete the exterior changes for Land Rover Discovery 4 - Nara Bronze, Bali Blue and Ipanema Sand.

All-new interior
The new interior for Land Rover Discovery 4 combines smooth, flowing surfaces with significant reduction in the complexity and number of controls. It provides a much softer, more premium all-round interior ambience, but still in keeping with the signature Discovery architectural theme.

The new console is now inclined towards the driver, improving visibility and access to the controls. It looks more akin to that in the Range Rover Sport than the outgoing Discovery 3. The Terrain Response control is now more prominently located at the front of the centre console, making way for the cup-holder in a more accessible position, mid-way along the console.

All models feature a new steering wheel, with revised switch layout for driver information, remote audio controls, cruise control and heated steering wheel.

A choice of natural-finish woods, along with stitched and wrapped facia, door casings and centre console, add to the crafted bespoke feel. There are also two new interior contrast colours, a mid-tone Nutmeg and a darker Arabica, complementing the existing Almond light interior colourway.

New seating is introduced for rows one and two, with a new, extended front seat cushion profile to improve support and seating comfort and, for the first time, the front seats feature height-adjustable head restraints in place of the traditional seat mounted grab handles. HSE vehicles specified with the Premium Leather pack also feature electrically adjustable side seat bolsters, allowing front occupants to tailor their seating's support.

For convenience, the electric seat memory controls are relocated to the door casing.
New Interior Mood Lighting adds the finishing touch to the interior, with the introduction of white LED's to cast subtle halos around the metal-plated interior door handles and pockets. The fascia and centre console area, complete with soft-stitching, and switchgear highlighted in "Noble" finishers, also benefit from the interior mood lighting when vehicle lights are on.

Technology made simple
The Land Rover Discovery 4 is packed with easy-to-operate and useful features, not technology for technology's sake. The aim throughout is to simplify the operation, to help make journeys more relaxing and stress-free

Inside and out, the Land Rover Discovery 4 gains a raft of relevant new technology, to improve the driving experience.

The navigation system adopts an easy-to-use navigation structure which now also features 'towards guidance'. This supplements the junction map and icon-based information with details of the actual road signage viewed by the driver along the route.

The new Portable Audio Interface allows connectivity to an array of personal audio storage devices, USB sticks and MP3 players, enabling the various devices' functions to be accessed and controlled via the facia-mounted touch-screen system. One of the connectivity ports is a dedicated Apple i-PodTM point made exclusively by Land Rover, for continued functionality in extreme driving conditions, by helping to prevent the device coming loose from the socket.

A new 5-inch Thin Film Transistor (TFT) driver information screen is also introduced with Land Rover Discovery 4. Sitting within the re-designed instrument cluster, the message centre display ensures key information is communicated in a clean, simple and user-friendly manner.

And a purer, crisper radio sound is now available thanks to the introduction of Digital Audio Broadcasting (DAB) in most European and Asian markets, and HD radio in the US. Along with the fine listening experience, comes additional features such as news headlines, song title and artist information.

Cutting edge user-friendly technologies
Outside the vehicle, convenient and relevant new systems enhance safety and security.

The new front headlights incorporate high beam assist technology. This can automatically switch on high beam headlights where external light levels are below the system's threshold. Importantly, the system is also designed to detect preceding and approaching traffic, and in a split second will automatically switch back to low beam to avoid dazzling others.

The new remote entry key emits the signal required for passive entry into the vehicle, by the holder of the key simply touching the door handle, without using the'unlock' button on the key fob. The new key also generates the signal required for the Push Button start of the vehicle. Sophisticated sensors recognise the presence of the key in the vehicle, confirm security credentials and then accept the 'start' command via the new fascia mounted start/stop push button.

No less than five digital cameras make up the new surround camera system, relaying to the touch-screen a near 360-degree view. The cameras function immediately the vehicle is started, and can be used at speeds up to 11mph, with options for selecting and zooming in to assist with close quarter parking and with towing.

The 'tow assist' function (selected from the touch screen menu) helps perform accurate towing manoeuvres. The wide field of views on the side cameras give a clear view of the reversing trailer: the images are electronically manipulated to provide an undistorted view, with guide lines overlaid on the rear camera image to illustrate both the vehicle and trailer's trajectory.

Specific characteristics such as type of trailer, number of axles and width guides can be fed into the system to enhance the system outputs.

Another towing aid, Trailer Stability Assist, detects trailer oscillations by monitoring key vehicle behaviours, such as uninvited steering movements and slight vehicle swing in response to trailer behaviour. In these circumstances, the system can initiate engine torque reduction and braking interventions to bring the towing back under control.

Mercury Mountaineer, 2006

 

 

 

 

 

•  Mercury Mountaineer, 2006

The Mercury Mountaineer is a luxury SUV manufauctured by the Mercury brand name, owned by the Ford Motor Company. The Mountaineer shares many features with the Ford Explorer, and in terms of hardware, the vehicles are virtually identical. Externally, they are styled somewhat differently, and the Mountainer is positioned with a more upscale interior, with the Mountaineer's MSRP coming in at $1,000–6,000 more than the Explorer. It has been mildly redesigned for the 2006 model year due to a new frame, but looks very similar to its previous model.

For 2006, the Mountaineer was redesigned. The new Mountaineer was all new, though it closely resembles the previous model. The Mountaineer was mounted on a new frame, and it offered a more upscale interior, to make up for the cut Lincoln Aviator. This Mountaineer got new wheels and HID headlights, a feature not found on previous Mountaineers.

Volvo S60 Concept, 2009

 

 

 

 

 

 

 

 

•  Volvo S60 Concept, 2009

The Scandinavian inspiration
The front of the Volvo S60 Concept sports the enlarged iron mark in the trapezoidal grille. The two lamps that flank the grill emphasise the vertical stance of the front and highlight the bonnet's V-shape. The angled headlamps flow up into the strongly sculptured bonnet and combined with the lower air intake's reverse trapezoidal shape, this gives the concept car a very expressive "face".

Viewed from the side, the concept car's slim coupe roofline and window graphics are accompanied by an entirely new shoulder line, forming a gentle double wave, stretching from the headlamps all the way to the rear. Both the seven-spoke 20-inch wheels and the tread of the low-profile tyres have been specially designed, while the bronze-painted brake callipers match the "Warm Liquid Copper" livery.

The unique rear parallelogram doors offer a spectacular show when they are opened and closed. Door opening is initiated by pressing a button and the movement starts off in the traditional way. In the next phase, the forward section swings out away from the car's body and the door glides parallel with the side of the car until it reaches its end position by the rear wheel. Since the car does not have a B-pillar between the front and rear seats, this door configuration offers exceptionally generous entry and exit access.

The transparent attachment of the door mirrors illuminates and becomes part of the indicator function. The panorama roof is another ingredient that contributes to the concept car's airy Scandinavian aura.

The Viking longboats in the headlamps
In each of the headlamps, the lights create a silhouette of two miniature Viking longboats sailing side by side, one for main beam and one for dipped beam. When driving in the dark, the light is reflected from the concealed, upward-facing High Performance LED bulbs, projected ahead by the ships' filled sails.
A closer look reveals more detail. The compact cooling system for the LED bulbs has protruding cooling blocks made out of aluminum, semi-visible under the ships' hulls. This design creates the illusion of shimmering glass panels that float above a dark and mysterious Scandinavian sea.

The Inspiration from the racing track
The tail lamps, which follow the curve of the rear shoulders, are as advanced as the headlamps. When switched off, the lamp panels show no trace of the traditional red or yellow. But when activated, the position marker lights, brake lights and turn indicators come on in their correct colours with the help of LED bulbs. The solid glass panel is sectioned into horizontal "slices" that create the visual impression of a three-dimensional architect drawing when the lights come on.
At the rear there is also a retractable diffuser that adjusts with vehicle speed to give better aerodynamic properties.

New technology detects pedestrians in the danger zone
The Volvo S60 Concept also presents a safety innovation that can detect a pedestrian who steps out into the path of the car and the car's full braking power is automatically activated if the driver does not respond to the danger. The technology, Collision Warning with Full Auto Brake and pedestrian detection, will be introduced in the all-new Volvo S60.

Elevates the brand's image
The Volvo S60 Concept was created to pave the way for Volvo Cars in one of the automotive world's most focused segments, characterised by razor-sharp competition.

Toyota FT-EV Concept, 2009

• Toyota FT-EV Concept, 2009

The Toyota FT-EV concept shares its platform with the revolutionary-new Toyota iQ urban commuter vehicle. Already a huge hit in Japan, the iQ is lightweight and seats four passengers in comfort and security, while delivering exceptional mileage, sporty performance, unique refinements and a fun, youthful image.

Toyota FT-EV concept imagines an urban dweller, driving up to 50 miles between home, work and other forms of public transportation, such as high-speed rail. Although, for now, the Toyota FT-EV remains a pure concept, it represents a natural pairing of product strategies.
Though BEVs and new smaller vehicles like the iQ will be a key component of Toyota's sustainable mobility strategy, the conventional gas-electric hybrid, like the all new third-generation Prius, is considered Toyota's long-term core powertrain technology.

The first-generation lithium-ion batteries powering these PHVs will be built on an assembly line at Toyota's PEVE (Panasonic EV Energy Company, LTD) battery plant, a joint-venture production facility in which Toyota owns 60 percent equity. During its development, the new Prius was designed and engineered to package either the lithium-ion battery pack with plug-in capability, or the nickel-metal hydride battery for the conventional gas-electric system.
The 500 PHVs arriving globally in late 2009 will be used for market and engineering analysis. Lease-fleet customers will monitor the performance and durability of the first-generation lithium-ion battery, while offering real world feedback on how future customers might respond to the plug-in process.

Mercedes-Benz A-Class Coupe, 2009

 

 

•  Mercedes-Benz A-Class Coupe, 2009

With more than 500,000 units produced within three and a half years, the Mercedes-Benz A-Class is among the bestsellers in the Mercedes-Benz passenger car range. Now the latest generation of this compact car is showing itself to be more youthful, attractive and environmentally compatible than ever before. This is ensured by a completely revised design, high-grade appointments and new technical developments which further improve safety, comfort and economy. A convenient ECO start-stop function which reduces urban petrol consumption of these BlueEFFICIENCY vehicles by up to nine percent is now available for the high-volume models A 150 and A 170, for example. For the three-door A 160 CDI Mercedes-Benz has developed an additional BlueEFFICIENCY package which lowers the fuel consumption of the Coupé by more than eight percent, to 4.5 litres per 100 kilometres. Independent experts have acknowledged these great advances in the environmental field with an internationally valid environmental certificate, which the Mercedes-Benz A-Class is the world's first compact car to achieve.

Since its world premiere in 1997, the Mercedes-Benz A-Class has made a name for itself as a trendsetter and innovative leader in its class. Outstanding safety, great day-to-day flexibility and reliability have always been among the strengths of the Mercedes-Benz A-Class, which has so far captured the enthusiasm of about 1.7 million customers with its distinctive and versatile vehicle concept.

In spring 2008 Mercedes-Benz is presenting the five-door Saloon and the three-door Coupé in completely upgraded versions. Viewed from the front, this compact Mercedes-Benz now appears more youthful and self-confident than before. The sweeping lines of the newly designed headlamps harmoniously combine the front end and flanks, which literally appear to be cast from a single mould. The redesigned front bumper reinforces this impression; its lower air intake is now much larger, emphasising the width of the body. The radiator grille is also in a new design which underlines the progressive aura of the Mercedes-Benz A-Class.

Lines: ELEGANCE and AVANTGARDE with an even more pronounced styling emphasis
Design features at the front end provide more distinctions between the design and equipment lines of the Mercedes-Benz A-Class. While the louvres in the radiator grille of the basic version are painted in dark-grey, they are respectively in metallic atlas grey and high-sheen iridium silver in the ELEGANCE and AVANTGARDE lines, and are also visually upgraded by additional chrome strips. Discreet chrome trim strips further reinforce this impression. In the AVANTGARDE line, the front bumper also has a distinctive design which emphasises the arrow-shape of the front end and suggests greater agility.

When viewed from the side the different lines in the Mercedes-Benz A-Class are distinguished by wheel designs. While the basic model is equipped with 15-inch wheels and seven-spoke wheel embellishers as standard, ELEGANCE and AVANTGARDE are fitted with individually designed 16-inch light-alloy wheels. The new, larger exterior mirror housings and door handles are now painted in the vehicle colour for all model variants. The previous side rubbing strips have been replaced by discreet chrome trim strips, which provide additional visual highlights in the ELEGANCE and AVANTGARDE models.

The rear end of the Mercedes-Benz A-Class is dominated by a modified bumper and newly designed rear light clusters which extend well into the vehicle flanks. Both these features make the body appear wider and therefore more imposing. In the ELEGANCE and AVANTGARDE models the rear bumper is embellished with additional, reflector-look trim strips and chrome inserts. The new, ergonomically improved tailgate handle is chrome-plated in both lines, as is the oval exhaust tailpipe.

Interior: upgraded with larger stowage compartments and new fabrics
Mercedes designers paid particular attention to enhanced value when redesigning the interior, choosing new, high-grade upholstery fabrics and door linings. In the ELEGANCE and AVANTGARDE lines the seats are upholstered in an attractive combination of ARTICO man-made leather and fabric, which is available in three colours. In addition new decorative trim of smoke-grey, diagonally brushed aluminium enhances the interior of the AVANTGARDE line, while the dignified aura of the ELEGANCE models is heightened by wood trim. All variants of the Mercedes-Benz A-Class share a larger stowage compartment in the centre console and a newly designed cupholder between the front seats.

The luxury seat package with seat cushion angle adjustment and lumbar support, seat height adjustment for the driver's seat, a front armrest and a parcel net in the front passenger footwell is standard equipment for ELEGANCE and AVANTGARDE models.

Fuel economy: the A 160 CDI BlueEFFICIENCY consumes 4.5 litres
With fuel consumption figures between 4.9 and 8.1 litres per 100 kilometres, the new-generation A-Class is a model of fuel economy. Thanks to detailed improvements, the fuel consumption of the state-of-the-art direct-injection diesel engines has been reduced by more than eight percent or 0.5 litres per 100 kilometres compared to the preceding series. From autumn 2008 Mercedes-Benz will introduce a standard BlueEFFICIENCY package for the three-door A 160 CDI with a manual transmission, with further improvements in engine efficiency, aerodynamics, rolling resistance, energy management and weight. The sum of these measures achieves a fuel saving of 0.4 litres, which means that the A 160 CDI BlueEFFICIENCY has an NEDC consumption of just 4.5 litres per 100 kilometres. As a result the CO2 emissions of the 60 kW/82 hp Coupé are 119 grams per kilometre.

The BlueEFFICIENCY package also includes an aerodynamically optimised radiator grille. This has a closed-off interior face to reduce the airflow to the engine, though the CDI engine is still cooled effectively at all times. The suspension has also been lowered by ten millimetres to reduce the drag coefficient even further.

Mercedes engineers have exploited an additional fuel-saving potential by controlling the onboard power supply of the A 160 CDIBlueEFFICIENCY according to demand, and therefore on an energy-saving basis. A sensor constantly monitors the battery so that the output of the generator can be reduced for certain periods when the battery is well charged. This reduces the work required of the engine, which therefore consumes less fuel. To recharge the battery with optimum energy efficiency, the generator management system utilises the engine's overrun phases to produce electrical energy.

Start-stop function: the engine switches off automatically when idling
In the case of the petrol engines, Mercedes engineers have achieved NEDC fuel savings of up to 0.4 litres per 100 kilometres with a newly developed ECO start-stop function. From autumn 2008 this system will be available for the high-volume models A 150 and A 170 on request. It automatically switches off the engine when the driver shifts the manual transmission to neutral at a low speed while applying the brakes. If the conditions for engine switch-off are met, the driver is informed by a special display in the instrument cluster.

Within fractions of a second, and almost noiselessly, the engine is restarted as soon as the clutch is operated or the brake released. This rapid and comfortable engine start is a major advantage of the ECO start-stop function versus other systems of this kind. To this end Mercedes-Benz uses a starter generator which is linked to the crankshaft via the drive belt. As a result the engine starts much more rapidly and quietly than with the conventional starter. During a journey the starter generator feeds electrical power to the onboard network of the Mercedes-Benz A-Class.

Economy: nine percent lower fuel consumption in city traffic
With the ECO start-stop function the NEDC fuel consumption is reduced by a further 6.5 percent or so. The A 150 BlueEFFICIENCY (70 kW/95 hp) absolves a measured test journey with a fuel consumption of 5.8 litres per 100 kilometres, which corresponds to 139 grams of carbon dioxide per kilometre.

Even greater advantages can be achieved in normal road traffic, as the results of extensive practical trials have confirmed: Mercedes employees tested the system in 175 test cars, covering a total of around 1.2 million kilometres. Roughly half of this enormous mileage was covered in city traffic, where the new ECO start-stop function enabled fuel savings of up to nine percent to be achieved.

Ecology: the Mercedes-Benz A-Class is the first compact car with an environmental certificate
Practical trials such as this are of immense importance to Mercedes-Benz when it comes to evaluating new technologies. The environmental compatibility of vehicles is not only assessed on the basis of standardised emissions and fuel consumption measurement, but also taking into account the entire vehicle lifecycle - from production and many years of operation to eventual recycling and disposal. An analysis of more than 40,000 individual processes provides an overall picture and enables the development work to be objectively assessed.

This form of environmental audit is the basis of the environmental certificate according to the stringent international ISO standard 14062 (Design For Environment), which Mercedes-Benz is the world's only automobile brand to have received. This certificate also applies to the new-generation A-Class, confirming the considerable advances made in the field of environmental protection. An analysis over a vehicle mileage of 150,000 kilometres shows that CO2 emissions are around seven percent below the figure for the preceding model (W168) of 2004, for example. Nitrogen oxide emissions have been reduced by no less than 13 percent.

Even better results are achieved by the A 150 BlueEFFICIENCY with the ECO start-stop function. Thanks to this new technology, carbon dioxide emissions over the entire lifecycle are reduced by a further five percent, which means that the environmental audit shows a remarkable reduction in CO2 emissions by more than twelve percent compared to the preceding model.

Aspects other than favourable fuel consumption and low exhaust emissions are also important for the environmental certificate. For example the recycling concept of a vehicle: the Mercedes-Benz A-Class already meets the EU regulation coming into force from 2015, which prescribes a recycling rate of 95 percent. Plastic components with a total weight of 30.8 kilograms can be produced from high-grade recyclates - twice the figure achieved for the preceding model.

Safety: flashing brake lights warn following traffic
The adaptive brake light introduces technology from the luxury class into the compact segment, which therefore benefits from a further accident prevention system as a standard feature. Under emergency braking from a speed exceeding 50 km/h, the brake lights flash rapidly to warn following traffic, enabling drivers to respond quicker and prevent a collision.

Flashing brake lights are the result of extensive practical research covering the braking behaviour of drivers. Mercedes engineers found that the braking responses of drivers are on average 0.2 seconds faster in emergency braking situations if a flashing red warning is given in place of conventional brake lights. The stopping distance can be reduced by around 4.40 metres from a speed of 80 km/h, and even by around 5.50 metres from a speed of 100 km/h. If the A-Class is brought to a rapid stop from a speed exceeding 70 km/h, the hazard warning system is switched on in addition to the flashing brake lights.

the Mercedes-Benz A-Class sets standards in this market segment where occupant protection is concerned, with two-stage front airbags, belt tensioners in the front and for the outer rear seats, belt force limiters, active front head restraints and head/thorax sidebags. Mercedes-Benz has now added to this extensive safety technology with crash-responsive emergency lighting for the interior. This is switched on automatically following an accident of a defined severity, providing the occupants with better orientation and facilitating the work of the emergency services.

Parking assist: ultrasound and electric steering for easier parking
When finding and reversing into a parking space, drivers of the Mercedes-Benz A-Class will in future be aided by an active parking assist feature which is available on request for all model variants. Using side-mounted ultrasonic sensors, this system identifies suitable parking spaces on both sides of the road in passing, then informs the driver by means of a display. The sensors are active up to a speed of 35 km/h, and monitor the area to the left and right of the Mercedes-Benz A-Class. They measure the length and depth of possible parking spaces, indicating that the search is in progress with a " P " in the instrument cluster.

Once a suitable parking space has been found, an arrow appears in the display to inform the driver on which side of the road the parking space is located. If he engages reverse gear, acknowledges the display message and accelerates, active parking assist takes over the steering and automatically manoeuvres the car into the parking space. The driver only needs to accelerate and operate the brakes; the ultrasonic sensors of the PARKTRONIC system assist him in this by keeping him informed about the distance to the vehicle in front of and behind the Mercedes-Benz A-Class.

Active parking assist uses a total of ten ultrasonic sensors in the front and rear bumpers, as well as an electronic control unit which processes the sensor signals and calculates the best possible entry path into the parking space. This information is fed to the electromechanical power steering, whose electric motor performs the necessary steering movements of its own accord. The parking space only needs to be 1.30 metres longer than the Mercedes-Benz A-Class for this automatic parking procedure to take place - an indication of the great precision of this technology. Thanks to its very compact dimensions, a parking space with a length of just 5.18 metres or so is sufficient; there is currently no other car able to park automatically in such a small space.

Mercedes engineers have also added a new function to a well-proven support system: the Electronic Stability Program (ESP®) of the Mercedes-Benz A-Class now has an automatic hill-holder function which prevents the car from rolling backwards when the driver changes from the brake pedal to the accelerator when moving off on an uphill gradient. In these situations ESP® maintains the brake pressure for a short time, so that the driver can move off smoothly.

Audio: new units offer Bluetooth, a colour display and Europe-wide navigation
Like all the new 2008 Mercedes models, the Mercedes-Benz A-Class is available with further improved information, communication, navigation and entertainment systems - in other words infotainment. There is a choice of four optional head units:

Audio 5, Audio 20, Audio 50 APS and COMAND APS. From Audio 20 these incorporate a radio with twin tuner, colour display, a Bluetooth interface for a mobile phone, a telephone keypad, a CD-player, automatic volume adjustment and a connection for external audio units in the glove compartment. Audio 50 APS is also equipped with a Europe-wide DVD navigation system and a DVD drive, while the top-of-the-range COMAND APS features HDD navigation, a music register, a slot for SD memory cards and voice control. The LINGUATRONIC system operates the telephone, audio and navigation system by convenient whole-word commands. The driver need no longer spell out his wishes, but simply needs to say what he wants when entering a destination, selecting a radio station or accessing an entry in the telephone directory.

Interface: the "iPod" can be operated via the keys on the steering wheel
More scope for mobile musical enjoyment is provided by a newly developed, interactive media interface, which is able to connect an MP3-player, USBstick or other external audio unit with the infotainment system of the car. This means that external audio units can be conveniently operated using the keys on the multifunction steering wheel, while the titles of music tracks are shown in the instrument cluster and on the colour display in the centre console. While the portable audio unit is connected to the car via the media interface, its battery is charged. Connection of an iPod or similar requires a suitable cable which is available from the Mercedes-Benz accessories range.
