Mercedes-Benz has unveiled the latest addition to the SLK Roadster lineup, the 2012 SLK55 AMG. For this iteration of the diminutive droptop, AMG is employing a naturally-aspirated version of Mercedes-Benz’s 5.5-liter V8.

The new aluminum engine is good for 415 horsepower and 398 pound-feet of torque, which should be more than enough to motivate the little beast. To keep things eco-friendly somewhat greener, the new engine employs gasoline direct injection and a stop-start feature to help save fuel.
The V8 exhales through twin exhausts, which have flaps that open to deliver a throatier sound when your right foot comes down. All the go bits are mated to AMG’s seven-speed Speedshift Plus 7G-Tronic automatic cog box. Look for the hot-rodded SLK to arrive in showrooms early next year.
