Just having some fun speculation. Just read that the next generation C63 could have a 4L twin turbo V8 and AWD. Sounds like it could be a 4 door GTR.

I've never been much of MB fan but I respected their bad ass NA engines. This new generation of AMGs with AWD will be able to put some serious power down. I'm looking forward to some great comparisons with the M3/M4 in 2015.
