And that "claim" was fairly well debunked as pretty well impossible by multple forum members. In short the following are not compatible:
-A torque curve like the new M5
-A 7000 rpm redline
-420 hp and 400 ft lb of torque
Make a spreadsheet or do the math.
Something just have to give. I strongly suspect the car will indeed have about 400 ft lb of torque but quite a bit more than 420 hp. Under rating is also pretty likely IMHO.
