Question....what are the manufacturers 0-60 times based on?
Bought my Z4 3.0si coupe a year ago with an auto box and been trying to find out what the best way to pull off from rest is with out killing the box.
BMW quote a time of 5.7 sec, but how exactly do they achieve that? Do they expect you to rely on the torque limiter i.e. brakes on and accelerator flat out?
Any advice?
