I want to know what exactly was modified to the engine that's different from the s63 in the x5m. (Compression, cams, anyone??)
Compared to the version in the X5 M, the F10M engine has now Valvetronic and new "innovative solenoid valve injectors." This allows BMW to run a higher compression of 10:1 vs 9.3:1 in the X5 M. As you can see from the engine shots, they've also beefed up cooling. In other words, they've done quite a bit more to the engine than the raw hp and torque stats suggest.


Best regards,
