2011 Mercedes-Benz SLS AMG

The new Mercedes-Benz SLS AMG uses the familiar 6.2-liter AMG V-8, set back behind the front axle. Here it will produce 563 hp and 479 lb-ft of torque, an increase of 38 hp and 15 pound-feet compared to the current V-8. AMG claims that the handbuilt engines have more than 120 new parts, largely in the intake and exhaust system, the dry sump lubrication system, and the crank mechanism. The engine is also lighter (only 454 lbs), due in part to the use of aluminum instead of steel for the crankcase and the engine bolts, forged rather than cast pistons, and a magnesium intake manifold. The dry sump lubrication system uses a remote reservoir, eliminating the oil pan and allowing for a lower profile.

The engine's power is transferred to a rear-mounted, 7-speed dual clutch transaxle via a carbon-fiber driveshaft enclosed within an aluminum torque tube. The use of a rear transaxle helps the car achieve a 48/52 front/rear weight distribution.

The chassis uses aluminum double wishbones at all four wheels and composite brakes--or optional ceramic composite brakes (with telltale gold calipers)--to help keep the SLS on the road. Massive, 265/35 R19 front and 295/30 R20 rear Michelin Pilot Super Sports tires provide the grip--as much as 1.2g in lateral acceleration.
