BMW engines are just impressive. Even with the 300/300 setup the lighter 35i gives the S5 a run for its money.
Motorweeks method of getting 0-60 numbers may be different from other mags so going by the 1/4 mile numbers:
S5 13.4@105
S4 13.2@106

The slower (relative to x drive) 335i RWD has already been tracked at 13.5@104.
Pretty impressive considering the N55 at 300/300 is down on power.
