Test Driver Ratings & Comments

Acceleration commentsPerhaps it's the size/mass of the Gran Coupe, but this is the first time I've felt like this otherwise potent engine wasn't up to the task. Brilliant in a 3, adequate in a 5, but it feels sluggish off the line in this car and the feeling of real power/torque arrives in the midrange. Seems to resist pedal overlap unlike previous BMWs. Dunno why. Also, I couldn't manage to get any wheelspin at all with Trac off. Not a bad performance, but not what I'd call a thrilling one, either. Upshifts click off like clockwork and darned close to 100 mph in the quarter-mile.
Braking commentsThe very definition of fade-free brakes, holding steady between 110-111 feet for five consecutive stops. Straight as an arrow and it mattered not which Drive mode was selected; same distance, just varied amounts of dive. Very good brakes.
Handling commentsSkid pad: With ESC off, I found it difficult to maintain a steady line with the engine boost surging, lazy throttle response, and the unintuitive, disconnected steering. Plenty of grip, but no poise or ability to balance it on the edge. With ESC on, it was much happier and tracked true to steering input with the system using minor throttle adjustments to correct course. Slalom: Good initial steering response, but a thoroughly uncharacteristic BMW experience thereafter. Active suspension keeps the car unnervingly flat, the steering response was not linear or anything close to intuitive, and I never felt as if I knew what would happen cone-to-cone, much less run-to-run. Every cone was its own event, requiring "Active Learning" on my part. I had a hard time not hitting cones. BMWs have historically felt like an extension of my will, but no more. So sad for this day. This is a good 8/10ths car that falls to pieces at 10/10ths.
