Somewhat favorable, somewhat not, it’s the review from Autocar.

>It also feels naughtier on the road. It’s genuinely quick in any gear, with just enough added zest to make it noticeably quicker than the standard Cooper S.

Of course they also don’t like the Speedo. But, it would appear they aren’t fans of hitting the sport button.

>Just don’t bother pressing the ‘sport’ button. It sharpens the throttle response a smidgen, and is meant to make the steering more direct, but simply makes it heavier and less feelsome.
