2012 S63 Biturbo vs 2012 S65
Would love to hear from owners and ones that have driven them what they think.
You can get a Renntech tune for the 5.5TT and make it produce more hp and tq than a stock S65, plus other than the engine and tranny, all other components are pretty much identical and you're getting much better MPGs while saving $30-$40k if buying one used.
I guess its the way that the V12TT delivers the power that the 63 can't match, so smooth you can't even feel it..
