The new SLK350 has a 272hp V6 and new 6speed manual, new SLK55 AMG has a 360hp V8. Sadly no manual on the AMG V8 version.... Stylewise it's just the spy pics have indicated all along, and evolution of the current car with one major change, a SLR style front end. New Airscarf system keeps your neck warm during colder top down driving (!). New 7G-Tronic tranny optional for SLK350, and (standard) for the first time on a AMG product the SLK55 AMG. The V6 is an all new direct injection unit, MB also went back to 24V/DOHC technology, along with whole host of other tricks. The new car should surpass the 300K+ sales the old SLK did since it's fall 1996 launch.
