OFFICIAL PRESS RELEASE
Affalterbach, Germany, Mar 09, 2010
History: A tradition of top performance
Powerful eight-cylinder engines with a thrilling power delivery and an emotional sound experience � a traditional strength of AMG. The V8 power units from Affalterbach combine high-tech derived from motorsports with the smooth running and exemplary reliability that are the hallmarks of a Mercedes.
The impressive attributes of the powerful eight-cylinder engines produced by Mercedes-AMG have their origins in motor racing. Founded in 1967, the company started with the development of powerful racing engines, and soon used the resulting findings to develop high-performance road models. AMG is regarded as a pioneer in the customising/tuning sector, and over the last four decades it has developed into a manufacturer of exclusive high-performance automobiles thanks to continuous technical innovation.
AMG V8 engines have always been in a class of their own. It all started in 1971, with the 6.8-litre, 315 kW (428 hp) racing engine in the legendary 300 SEL 6.8 AMG. At the 24-hour race in Spa-Francorchamps (Belgium), this fast Mercedes saloon immediately secured a highly acclaimed class victory and second place overall. The powerful eight-cylinder racing engine made AMG known throughout the world overnight. Soon AMG also had a suitable engine available for S-Class customers in search of more power: on the basis of the 184 kW (250 hp) V8 engine of the 300 SEL 6.3, the company developed a 206 kW (280 hp) eight-cylinder unit which gave the luxury saloon the performance characteristics of a sports car.
More than 300 km/h in the 300 CE 5.6 AMG - "The Hammer"
Subsequent AMG high-performance engines also provided unprecedented driving pleasure in other Mercedes models. For example the five-litre V8 engine with 203 kW (276 hp), which gave the Mercedes-Benz 280 CE 5.0 AMG a dynamism previously unknown in this vehicle class in 1983. Just one year later AMG came up with a completely independently developed V8 unit featuring four-valve technology and an output of 250 kW (340 hp) � a sensational figure at the time. In 1986 the V8 engine, which had meanwhile been uprated to 5.6 litres and an output of 265 kW (360 hp), gave the 300 CE 5.6 AMG a maximum speed of no less than 300 km/h � as was even reported on the evening television news . American fans respectfully referred to the fast AMG Coup� as "The Hammer". The last evolutionary stage of the eight-cylinder powerpack appeared in 1988: from a displacement of six litres, the four-valve unit developed a maximum output of 283 kW (385 hp) and a torque of 566 Newton metres.
As the sporty top model in the completely new Mercedes-Benz E-Class with the twin-headlamp face, the E 50 AMG had its debut in 1996 with a five-litre AMG V8 engine developing 255 kW (347 hp). One year later AMG surprised the motoring world with a 4.3-litre V8 engine in the C-Class: the C 43 AMG developed 225 kW (306 hp), and was also available as an Estate model. In 1997 AMG also presented the newly developed 5.5-litre eight-cylinder engine with 260 kW (354 hp), three-valve technology and twin-spark ignition. The M 113 initially gave effortless performance to the E 55 AMG, but within a short time it was also used to power other AMG high-performance cars such as the CLK 55 AMG, ML 55 AMG, SL 55 AMG, S 55 AMG, CL 55 AMG and G 55 AMG. Uprated to a peak of 270 kW (367 hp) and 510 newton metres, it also gave a suitably dynamic performance to the C 55 AMG, the CLK 55 AMG Coup� and Cabriolet and the SLK 55 AMG.
Displacement of 5.5 litres, eight cylinders and supercharger technology
As a major milestone in the history of AMG engine development, the supercharged 5.5-litre V8 (M 113 K) with up to 380 kW (517 hp) and 720 newton metres of torque celebrated its debut at the end of 2001 in the SL 55 AMG, followed by the S 55 AMG, CL 55 AMG, E 55 AMG, G 55 AMG Kompressor and the CLS 55 AMG. The supercharged AMG 5.5-litre V8 unit was voted the clear winner in the "International Engine of the Year Awards" in 2003. In the "Best Performance Engine" category, it won a victory over well-established competitors by a wide margin. A further development of the supercharged V8 engine developing 428 kW (582 hp) and 800 newton metres powered the highly exclusive CLK DTM AMG. The supercharged V8 engine of the Mercedes-Benz SLR McLaren presented in 2003 was a special case, as it was a completely independently developed, high-tech eight-cylinder with dry sump lubrication. This delivered an impressive peak of 478 kW (650 hp) and 820 newton metres.
Naturally aspirated eight-cylinder engine with a displacement of 6.3 litres and an output of up to 420 kW (571 hp)
2005 saw the debut of the AMG 6.3-litre V8 engine; depending on the model, this naturally aspirated, high-revving unit known as the M 156 developed up to 386 kW (525 hp) and 630 newton metres. In 2009 this V8 engine currently used in nine AMG high-performance cars won the "International Engine of the Year Award� in the "Best Performance Engine" category.
Exclusively reserved for the brand-new Mercedes-Benz SLS AMG super-sports car, the M 159 also has a displacement of 6.3 litres, a peak output of 420 kW (571 hp) and a maximum torque of 650 newton metres. To ensure a low centre of gravity and allow maximum lateral acceleration, this eight-cylinder unit designed as a front-mid-engine features dry sump lubrication.
"AMG Performance 2015" as the continuation of a success story
Mercedes-AMG is continuing this impressive story with the AMG 5.5-litre V8 biturbo engine and the AMG SPEEDSHIFT MCT 7-speed sports transmission. The "AMG Performance 2015" strategy reflects the company's commitment to continuous reductions in both the fuel consumption and emissions of new models � also with future engine/transmission combinations � while reaching new heights with the central brand value of "performance".
