2012 Mercedes-Benz SLK55 AMG
With a peak output of 415 horsepower and 398 pound-feet of torque, the new V-8, codenamed M152, ensures that the 2012 SLK55 AMG is the most powerful SLK of all time.
However, it’s also quite frugal thanks to cylinder deactivation technology, direct injection, and an engine stop-start system.
It sees the SLK55 AMG accelerate from 0-60 mph in 4.5 seconds, easily hit an electronically limited top speed of 155 mph and return a claimed gas mileage of 28 mpg for the European combined cycle (EPA rated are yet to be announced).
We’ve already gone into great detail describing the new engine’s specs, but here’s an official video from AMG outlining some of the highlights.
