Test Driver Ratings & Comments

Acceleration commentsThere's nearly a full second between slowest (default Comf + Drive) and quickest (Sport + Auto-upshift manual) modes, and yet not quite enough power to spin the rear tires with traction control shut off. Upshifts in any mode are exceptionally smooth and reasonably quick. The car will still upshift at redline even in Manual mode. The turbocharger doesn't make itself known at all; no lag, no swell of torque, and no whine/whistle. Most folks would never know.
Braking commentsMedium-firm pedal from first to last stop. Good heat capacity in the brakes, as the best stop came on the third stop. Arrow-straight, little dive, no drama.
Handling commentsSlalom: While this isn't an analogous experience to every 3 Series that preceded it, it is a nimble car with high limits and quick reflexes. It retains only a modicum of feedback for driver involvement: The steering isn't what it once was in terms of feel, nor does one "drive it off the rear tires" like before. What it is now is well-balanced and competent rather than invigorating and involving. Skid pad: The throttle offers just enough response to be useful in transferring weight front/rear. Highly polished and poised.
