Audi A6 Avant
The top gasoline engine, the 3.0 TFSI, has been comprehensively revised. The engine developers have also completely redesigned numerous aspects of the 3.0 TDI clean diesel, which is available with either 218 HP or 272 HP. The 3.0 TDI clean diesel biturbo produces 320 HP. Another version with 326 HP, which can be boosted briefly to 346 HP, powers the A6 3.0 TDI competition and A6 Avant 3.0 TDI competition special‑edition models, with which Audi is celebrating the 25 years of TDI technology.
The high performance diesel is paired with an 8 tiptronic. All other engine variants work together with either a newly designed six‑speed manual transmission that is particularly lightweight and low-friction, or a seven‑speed S tronic. In the versions with front-wheel drive, a fully redeveloped dual-clutch transmission replaces the multitronic. In engine configurations starting at 272 HP, quattro permanent all‑wheel drive can be supplemented with the sport differential, which actively distributes power between the rear wheels.
The chassis with its sophisticated wheel suspensions also combines supreme comfort with sporty handling. The Audi drive select dynamic handling system is standard, and Audi offers a choice of two sport suspensions and adaptive air suspension as options. In the A6 Avant 2.0 TDI ultra with 140 kW (190 hp), the springs are made of glass fiber-reinforced polymer (GFRP) - an Audi innovation that saves approximately 4.4 kilograms (9.7 lb) of weight, reduces fuel consumption and improves both driving precision and vibrational comfort. The wheels measure between 17 and 20 inches in the diagonal.
An RS6 version is also available in the Avant body style with a 4.0 Bi-Turbo TFSI engine which produces 560 HP and 700 NM (516.29 lb-ft).
BMW 5-Series Touring
The appeal of Sheer Driving Pleasure in a premium executive class car is set to grow even further in both strength and reach with the launch of the new BMW 5-Series model family. The host of optimised details included in all variants of the new BMW 5-Series have led to (in some cases significantly) reduced fuel consumption, but with no drop-off in sporting ability. Indeed, some models now actually offer improved performance. Added to which, all engine variants now meet the stipulations of the EU6 exhaust gas standard.
A new entry-level diesel variant, additional models equipped with xDrive all-wheel drive and an even more powerful yet also more efficient range-topping V8 power plant join the action, completing an engine line-up that now covers an output spectrum from 143 HP to 450 HP. The new BMW 5-Series Sedan and new BMW 5-Series Touring can be specified with a choice of four petrol and six diesel engines. Beyond this, the Sedan also comes in BMW ActiveHybrid 5 full-hybrid and BMW M5 high performance guise. The engine line-up for the new BMW 5-Series Gran Turismo comprises two petrol units and three diesels.
The cutting-edge chassis technology underpinning all the models in the BMW 5-Series family delivers a balance of dynamic performance and ride comfort without precedent in this market segment, while the Electric Power Steering system comes with Servotronic speed-sensitive power assistance as standard. The BMW 5-Series Touring and BMW 5-Series Gran Turismo are also fitted as standard with automatic self-levelling air suspension at the rear axle. Among the options available for all members of the BMW 5-Series family are the Integral Active Steering and Adaptive Drive systems, which no other model in this segment offers. Targeted enhancements of acoustic and suspension comfort in the BMW 5-Series Gran Turismo, meanwhile, lend even further emphasis to its role as the supreme long-distance specialist of the line-up. The Sedan and Touring have likewise made notable advances in these areas.
BMW TwinPower Turbo technology ensures an exemplary balance of driving pleasure and fuel consumption across the engine range. In the new entry level diesel engine, which powers the BMW 518d Sedan and BMW 518d Touring, this package of technology consists of a turbocharger with variable inlet geometry and common rail direct injection with solenoid valve injectors. The 2.0 L engine develops a maximum output of 143 HP, generates peak torque of 360 NM (266 lb-ft) and accelerates the new BMW 518d Sedan from 0 to 100 km/h (62 mph) in 9.6 seconds. The 4 cylinder unit burns an average 4.5 - 4.9 litres of fuel per 100 kilometres (equivalent to 62.8 - 57.7 mpg imp) in the EU test cycle (CO2 emissions: 119 - 129 grams per kilometre, depending on the gearbox and tyre format specified).
The selection of diesel power plants available for the Sedan and Touring includes two four-cylinder variants - fitted in the BMW 520d producing 184 HP and the BMW 525d with 218 HP - and three 6 cylinder units. With average fuel consumption in the EU test cycle of 4.5 litres per 100 kilometres (62.8 mpg imp) and CO2 emissions of 119 grams per kilometre, the new BMW 520d matches the figures of the 520d EfficientDynamics Edition it replaces.
Further up the range, the BMW 530d develops 258 HP and the BMW 535d produces 313 HP. And rounding off the line-up are two M Performance cars: the BMW M550d xDrive Sedan and BMW M550d xDrive Touring. They also use a 3.0 L inline 6 engine deploying M TwinPower Turbo technology with three turbochargers to deliver unrivalled peak output of 381 HP and maximum torque of 740 NM (546 lb-ft). Three diesel engines are available for the new BMW 5-Series Gran Turismo, powering the BMW 520d Gran Turismo, BMW 530d Gran Turismo and BMW 535d Gran Turismo.
The new generation of the V8 engine with BMW TwinPower Turbo technology for the BMW 5-Series model family takes to the stage armed with a 10 per cent rise in output yet also significantly reduced fuel consumption. The eight-cylinder unit, found under the bonnet of the BMW 550i Sedan, BMW 550i Touring and BMW 550i Gran Turismo, now also combines its two twin-scroll turbochargers and High Precision Direct Injection with VALVETRONIC fully variable valve control. The power plant generates 330 kW/450 hp and maximum torque of 650 Newton metres (479 lb-ft) from its 4.4-litre displacement. The new BMW 550i Sedan, for example, sweeps from 0 to 100 km/h (62 mph) in just 4.6 seconds. Its average fuel economy in the EU test cycle stands at 8.6 - 8.8 litres per 100 kilometres (32.9 - 32.1 mpg imp). CO2 emissions come in at 199 - 206 g/km, depending on the tyre format specified.
As well as the BMW 535i Sedan and BMW 535i Touring models, the multi-award-winning straight-six with 225 kW/306 hp also powers the BMW 535i Gran Turismo. A pair of four-cylinder petrol engines is likewise available for the Sedan and Touring. The engine powering the BMW 520i develops 135 kW/184 hp, while the unit offered for the BMW 528i from the launch of the new BMW 5-Series boasts revisions to various details and delivers 180 kW/245 hp.
The Sedan and Touring variants of the BMW 520i, BMW 528i, BMW 535i, BMW 518d, BMW 520d and BMW 525d are fitted with a six-speed manual gearbox as standard. Each of those models can also be specified as an option with the extremely fast and precise, not to mention extraordinarily efficient, eight-speed automatic transmission provided as standard for the BMW 550i, BMW 530d and 535d, as well as all variants of the BMW 5-Series Gran Turismo. The eight-speed automatic now comes with a coasting function and can also be ordered with shift paddles on the steering wheel. Shift paddles are also included with the eight-speed sports automatic transmission, a standard feature of the BMW M550d xDrive, which stands out with its ultra-impressive shift dynamics.
Additional models with BMW xDrive intelligent all- heel drive
The selection of engine variants that can be combined with the BMW xDrive intelligent all-wheel-drive system has also been expanded. The BMW 520d xDrive Sedan and BMW 520d xDrive Touring are both new additions to the range, the electronically controlled distribution of drive between the front and rear axle giving them a noticeable increase in traction and directional stability, not to mention an even sharper dynamic edge through quickly taken corners.
All-wheel drive is also available as an option for the Sedan and Touring versions of the BMW 528i, BMW 535i, BMW 525d, BMW 530d and BMW 535d, and the BMW 550i Sedan. The M Performance cars channel the power from their 6 cylinder diesel engines through all four wheels as standard. All the models in the BMW 5-Series Gran Turismo line-up - with the exception of the BMW 520d - can be ordered with xDrive.
An M5 Touring version is also available with a 4.4 L twin-turbo engine, which produces 560 HP and 680 NM (502 lb-ft).
Mercedes-Benz E-Class T-Model
With three completely newly developed 4 cylinder engines, the Mercedes-Benz E-Class also remains one generation ahead where diesel technology is concerned. These engines feature latest-generation common-rail direct injection, fast piezo-electric injectors, improved exhaust gas recirculation and an innovative twin turbocharger, making for fast responsiveness and good performance characteristics. To express this in figures, the E 250 CDI with 204 HP and 500 NM develops a 25 percent higher torque than the previous V6 diesel engine, but uses around 23 percent less fuel at only 5.3 litres per 100 kilometres (combined NEDC consumption). This corresponds to 139 grams of CO2 per kilometre.
The new 4 cylinder diesel engine also powers the E 220 CDI with 170 HP and the E 200 CDI with 136 HP, also with a fuel consumption of only 5.3 litres per 100 kilometres.
The top model in the new Mercedes-Benz E-Class diesel range is the six-cylinder E 350 CDI with an output of 231 HP, which uses 0.5 litres per 100 kilometres less fuel than the previous E 320 CDI. From autumn 2009 the V6 diesel will also be available as a BlueTEC model with the world's best emission control technology. The E 350 BlueTEC develops 211 HP and meets the EU6 exhaust emission standards planned for 2014. All the other engine variants in the new Mercedes-Benz E-Class meet the EU5 limits.
Petrol engines: 20 percent fuel saving thanks to direct injection
The E 200 CGI and E 250 CGI are equipped with the newly developed 4 cylinder direct-injection engine with a displacement of 1.8 litres, turbocharging and variable intake and exhaust camshafts. The E 200 CGI 184 HP is equipped with a 6 speed manual transmission and the ECOstart/stop function as standard, and consumes only 6.8 litres of premium petrol per 100 kilometres (combined NEDC consumption, provisional figure). This equates to 159 grams of CO2 per kilometre.
In the E 250 CGI 204 HP, which has a five-speed automatic transmission as standard, maximum torque is now 310 newton metres, which represents an increase of more than 26 percent over the previous V6-engine. At the same time the NEDC fuel consumption is reduced by over 20 percent to 7.4 litres per 100 kilometres, equating to 175 grams of CO2 per kilometre (provisional figures).
As before, the E 350 CGI with direct petrol injection 292 HP and the top of the line E 500 388 HP are included in the range of engine variants in the new Mercedes-Benz E-Class. Detailed improvements have reduced the fuel consumption of these V6/V8 models by up to 0.6 litres per 100 kilometres. As a product from Mercedes-AMG, the new high performance E 63 AMG develops 525 HP.
The V6 and V8 models are equipped with a 7 speed automatic transmission and steering wheel selector lever as standard.
On request the V6 models E 350 CDI and E 350, as well as the eight-cylinder E 500, are available with latest-generation Mercedes all-wheel drive. This system distinguishes itself from previous all-wheel drive technology with greater efficiency, lower weight and more compact construction. These advantages produce noticeably better traction and fuel savings.
Both the Mercedes-Benz E-Class Saloon and Estate are available with a broad range of powerful and efficient petrol and diesel engines - all fitted with ECO start/stop function. New units include the BlueDIRECT 4 cylinder petrol engines in the E 200 and E 250, featuring the same sophisticated technology used in the latest 6 cylinder engine from Mercedes-Benz. Both of the 4 cylinder petrol engines meet the future EU6 standard, while the E 250 even complies with the strict criteria of efficiency class A.
The 6 cylinder petrol engines in the E 300 and E 400 are also state of the art - and for the first time feature a biturbo drive. The same advanced engine technology enables the V8 in the E 500 to achieve outstanding levels of performance and efficiency.
The four cylinder diesel engines in the E 200 CDI, E 220 CDI and E 250 CDI, well known for their efficiency and featuring the latest injection technology, are now even more economical, thanks among other things to a revised drive train. This is also the case for the E 300 BlueTEC HYBRID, currently the most economical luxury-class saloon, which in addition to the four-cylinder diesel engine also has a 27 HP electric motor under the bonnet.
The V6 diesel engines in the E 300 BlueTEC and E 350 BlueTEC have been revised and fitted with environmentally friendly and efficient BlueTEC technology, such that they currently already meet the future EU6 emissions standard. Virtually all of the E-Class models with diesel engines fall into efficiency class A, while the E 300 BlueTEC HYBRID is even classified in efficiency class A+.
