Mercedes four wheels that inspired from 6.3L V8 will have a different variant. The 6.3-liter AMG V8 will make a twin-turbo 5.5-liter V8 engine and the new engine models will start selling in the last quarter of 2010. The official unraveling of the engine will happen at next year’s Paris Motor Show following which the engine will hit the production facility. Mercedes wants to focus on better fuel economy whilst also reducing the emissions however performance is something the brand will not like to sacrifice as that could hurt the sales figures. The naturally aspirated V8 variant renders between 450 and 520hp with 440 lb-ft of torque. As far as the economy goes, the city numbers reflect 12mpg which are bettered on the highway by 7mpg.

Audi presents the highlight of the IAA 2009: the e-tron, a high-performance sports car with a purely electric drive system. Four motors – two each at the front and rear axles – drive the wheels, making the concept car a true quattro. Producing 230 kW (313 hp) and 4,500 Nm (3,319.03 lb-ft) of torque, the two-seater accelerates from 0 to 100 km/h (0 – 62.14 mph) in 4.8 seconds, and from 60 to 120 km/h (37.28 – 74.56 mph) in 4.1 seconds. The lithium-ion battery provides a truly useable energy content of 42.4 kilowatt hours to enable a range of approximately 248 kilometers.

The most important development related to batteries for electric drives are lithium-ion cells. Numerous experts throughout the world are working on their further development for use in cars, with the primary objectives being to reduce weight and increase capacity and performance. Audi has also opted for this technology, both for use in a hybrid production vehicle, such as the upcoming Q5 hybrid, and in the e-tron test platform

The requirement specification for the concept vehicle goes far beyond battery technology and the replacement of the combustion engine with an electric drive system, however. The Audi development engineers decided back in the concept phase to design practically every component and technology based on the new requirements of electric mobility. The interaction of all elements has a decisive influence on the factors efficiency, range and practicality.
