Seems those slippery spy photographers over a Autocar believe they have caught the upcoming versions of BMW's M3, Z4M, M6 and the 3-Sport. The real surprise seems to be that the coming Z4M will get the same V8 powerplant as the M3. Of course, this is likely a move to let the Z4M compete the new Porsche Boxster and AMG tuned Mercedes-Benz SLK55. The M6 will share the M5's V10, and will move faster than anything that large should be able to, with estimated 0-60 mph times around 4.5 seconds. If you can get past the Chris Bangle inspired designs, and dig fairly deep into your pocketbook, BMW has some mouthwatering vehicles in the works.
