"If you&amp;#039;re in the market for a compact rear-drive V-8 roadster, you have one choice: the SLK55 AMG, which is now powered by a naturally aspirated version of the twin-turbo 4-cam M152 5.5-liter found in the E63. With 415 bhp at 6800 rpm and 398 lb.-ft. of torque at 4500 rpm, this SLK is quick, able to hit 60 mph in 4.5 seconds, claims Mercedes. What&amp;#039;s more, the engine now has a start/stop mode and cylinder deactivation to save fuel, the latter a technology AMG says it borrows from F1. Top down, when the music of the V-8 is best, the engine stays in burbly 8-cylinder mode, routing power rearward via the 7-speed paddle-shift Speedshift gearbox, whose beautiful blip-downshifts make you sound like Schumacher (or Rosberg).        2012 Mercedes-Benz SLK55 AMG         2012 Mercedes-Benz SLK55 AMG   "^^<http://www.w3.org/2001/XMLSchema#string>
