Test Driver Ratings & Comments

Acceleration commentsAfter going through the various drive modes (Eco Pro, Comfort, Sport, Sport Plus), and the transmission options, (Drive, Sport, Manual), I discovered a dedicated Launch Mode indicated on the instrument panel. It's effective and cuts a half-second from acceleration times across the board. Also, I discovered the transmission short-shifts in Drive in modes other than Sport or Sport Plus where it will upshift at the indicated redline rather than 500 rpm shy as in other modes. It also will hold gears (without upshifting) in Sport or Sport Plus. That all said, what an engine! This should in no way be considered a consolation engine if the 435i is out of reach. There's plenty of grunt down low in the rev range and exhilarating power as the tachometer swings up toward the redline. The raspy intake/exhaust is an unexpected treat, too.
Braking commentsUntil we had conducted this simulated panic stop test, I wasn't a fan of these optional M-Sport brakes. In everyday use, the pedal lacks feel as it begins to travel and packs a surprising amount of effectiveness with little effort. At the test track, however, the benefits were highly evident: Short stopping distances and near-zero reduction in effectiveness and high-thermal capacity. The feel the pedal lacks in everyday, gentle use reappears with gusto when applied with a heavy foot for maximum performance. Very good brakes for the enthusiast driver.
Handling commentsSlalom: While the steering lacks tactile feedback in the traditional sense, it is laser precise and with the Dynamic Handling package's variable-ratio setup it also gains effectiveness the further off center the driver turns the wheel (unlike previous BMW Active steering). It's easy to approach the limits with confidence and measured aggression. Use the throttle or steering too abruptly, however, and the electronic stability control (ESC) will intervene. There's a noticeably longer leash with traction control disabled, but there's still an option to shut both traction and stability control off completely. Skid pad: I really expected to see a 0.90g or greater result here because as equipped, this 428i feels like it has a boatload of grip. Steering again could benefit from more feedback, but it looks like those hydraulic-steering days are gone.
