CanadianDriver recently posted their test drive of the R56 Cooper. Interestingly enough, their review car had the 6 speed automatic transmission.

>Though I prefer manual transmissions, I did enjoy the optional six-speed Steptronic automatic transmission in my test car. Gearing off the line is just right, allowing quick starts, and shifts are smooth and well-timed. The transmission shifts down automatically as you coast to a stop, or when braking while going downhill to help slow the car. But with just 118 horsepower at 6000 rpm and 114 lb-ft of torque at 4,250 rpm, there is a definite lack of mid-range torque, such as when pulling out to pass on the highway.

>However, the optional Sport mode (which is part of the optional $1,900 Sport Package) transforms the Cooper’s performance by adjusting transmissions shifting points higher, injecting an extra dose of power, and firming up the steering. Press the Sport button next to the transmission lever, and the Cooper seems to leap off the line, changing up automatically at about 4000 rpm instead of between 2000 and 3000 rpm. Acceleration feels much quicker and the car sounds and feels much sportier. My only complaint is that the engine revs higher when cruising creating more noise in the cabin.
