It's not easy to replace flame surfacing, the Bangle butt, and iDrive with a new car that's just as radical. Without appearing to try, BMW has pulled this off with equally controversial styling and potentially infuriating new technology. American luxury-car buyers will have the choice of just one version when it launches in November: the 750i, which means we get it only with the new 4.4L twin-turbo V-8, making 407 hp and 442 lb-ft in Euro trim. The engine first appeared in the X6, in which it is rated 400 hp and 450 lb-ft for the U.S. BMW says fuel efficiency is 1.8 percent better than the outgoing 750i, achieves ULEV2 and EU 5 emissions standards, and is the most efficient car in its class.
The other radical new option is Integral Active Steering, which controls the steering angles, front and rear. Like four-wheel steering from, say, GMC and Honda before it, the rear wheels turn (up to three degrees, either way) with the front wheels at low speeds, opposite them at higher speeds. The 7's turning radius is tightened, making the car feel smaller than it is in tight places. Turn off the Dynamic Stability Control completely and you can steer with the throttle and bring the tail out, but only within limits of what is still a very large car. Despite an 82-lb weight reduction, including more standard equipment on the new model, it's still too big and heavy to drift through left-right transitions.
