| Test Driver Ratings & Comments | |
|---|---|
| Acceleration comments | No matter what I tried, the quickest runs were in "Drive." I tried manual shifting and brake torquing and they were all slower. Upshifts are smooth but very slow. The batteries recharged quickly after each run, so performances remained consistent. |
| Braking rating | Very Good |
| Braking comments | Uncharacteristically soft, long-travel pedal for a BMW, but fade was not an issue at all. Straight, steady stops and zero ABS flutter/buzz. |
| Handling rating | Good |
| Handling comments | Slalom: Feels more capable than it truly is, and the non-defeatable stability control (despite a "DSC Off" light after pressing the button) makes runs inconsistent. Smooth input is the key, as any midcourse adjustment results in massive DSC intrusion. Understeer creeps in as limit is approached. Skid pad: With the non-defeatable DSC, runs were virtually identical, with mild understeer kept in check with a closing throttle. Steering gets rather heavy. |
