I would guess that the Z4 35i is slightly quicker than a 335i but not quite as quick as a 135i. The Z4 weight is in between the others and all have the same gear ratio in the 6spd manual. A Z4 DCT would have a slight advantage. It also has a slight rear weight bias for better traction.

Bottom line, all are so close, it depends more on driver skill, and a successful launch.

FYI, The Z4 is among the quickest cars I've owned but not the quickest.
A '95 3000GT VR-4 had 320hp and AWD. Easy to launch hard. Best 0-60 reported was 4.8.
An '02 M5 had 394hp and limited slip. Best for it was 4.6.
My '05 550i with sport auto has a best time of 4.9.
The Z4 35i DCT best time is 4.8. Although it doesn't feel as quick as the 550i.
Of all the cars, the M5 felt the quickest. Its problem was smoking the tires if too aggressive. But the differences are so minimal that I'd probably not be consistently faster in one over the other.
