The new flagship performance sedan from Munich is the 2017 BMW Alpina B7 xDrive. Alpina is BMW’s tuner of choice, and it designs customized features to integrate precisely with the factory build. The B7’s 4.4-liter twin-turbocharged V8 is massaged to deliver a nice, round 600 horsepower, and a torque figure nearly as impressive at 590 pound-feet available from just 3,000 rpm. That’s a full 80 hp more than the previous-gen Alpina B7.
Here, Alpina has installed two specially developed turbos positioned within the ‘V’ of the engine, featuring bigger inlets and outlets. The engine itself has been revamped: there are new pistons, spark plugs and a stainless steel Alpina sports exhaust. This reduces back pressure and weight, and comes with the necessary valves for additional noise.
All that muscle is channeled through an eight-speed automatic to all four wheels (as you might have guessed from the new xDrive handle). The result is an Autobahn-blitzing 0-60 time quoted at just 3.6 seconds – 0.8 seconds quicker than its predecessor – and a top speed estimated at 193 miles per hour—perfect for the German Autobahn’s.
Those would have been considered supercar figures not that long ago, but are delivered here in a luxury sedan as big as they come. They also stand up pretty well to the forced-induction eight-cylinder competition in the Audi S8 Plus, Jaguar XJR, Maserati Quattroporte GTS, and Mercedes-AMG S63.
Keeping all that momentum under control is an air suspension with adaptive dampers, active roll bars, and four-wheel steering. It’s all mounted to 20-inch wheels (21-inch forged rims are also available upon request) wearing Michelin Pilot Super Sport rubber and packing oversized brakes measuring 15.5 inches at the front (with four-piston fixed calipers) and 14.5 inches (with floating calipers) at the back. Of course it also benefits from all the advancements that the Bavarian automaker developed for the latest 7 Series, but takes things a step further with a specific aero kit and an interior decked out in even more upscale leather and trim.
The Alpina B7 will be available in September and we’ll have a better idea of pricing later this year.
