Car and driver drove the 1-M quite consistent with the Autobuild article:
Although, it was sitting in the passenger seat, it gives a precise idea of most of these things, if not all (except the motor code and exact weight specs).
Footnotes:
- Still N54 engine with 335 HP
- No mention worthy exhaust sound let alone the wail of a typical M car
- Low-revving engine much like X5 M, X6 M and F10 M5
- Weighs around 3400 - 3500 lbs
- Still some turbo lag
- Handles well
