Though we focused on the new engines in the 2011 BMW 535i and 550i in our early post, the 528i sedan is actually the best-selling model of the 5 Series line. It will turn up here a few months after the F10 5 Series goes on understanding in the U.S.

It'll also make quite a bit more power than the 2010 car. BMW rates the 2011 BMW 528i's normally-aspirated, magnesium/aluminum, 3.0-liter (2996cc) inline six-cylinder at 258 horsepower at 6,600 rpm and 228 pound-feet of torque from 2,600 rpm. Compare that to the 2010 528i's 230 hp at 6,500 rpm and 200 pound-feet at 2,750 rpm.

And just like the more powerful 5 Series cars, the 528i will be acquirable with the either the new six-speed manual gearbox with dry-sump oiling, or more realistically for most customers, the new ZF eight-speed automatic transmission (with paddle shifters if you buy the Sport package).

Along with the rear-wheel-drive 528i will come all-wheel-drive xDrive versions of every 5 Series model — 528xi, 535xi and 550xi. BMW still hasn't decided whether to give us another 535xi auto because it's such a slower seller in the U.S. — and because it's thought that the 535i Gran Turismo will pick up the slack and then some. In mid-2011, we'll see a diesel 5 Series, the 535d, which will a 3.0-liter inline-6, but with a single, twin-scroll turbocharger, instead of the twin turbos in the current 335d and X5 xDrive35d.

Two videos after the jump. One shows running footage of the 2011 5 Series, and the other is a design walkaround with Design Director Adrian van Hooydonk.
