i3 with REX is _not_ the fastest BMW from 0-40. i3 pure electric is faster, for one counterexample.

Having driven one for nearing 4 years, it's crazy fast.

Correct. "one of the fastest..." is more accurate. The new m4's beat the i3 0-30 but only by a few fractions.

In any event, it's very very fast for an urban commuter and I annoy plenty of people driving AMGs and Porsches in my clown car.
