Following the debut of the G11/G12 BMW 7 Series LCI last month, Alpina has now unveiled the new B7 xDrive that is based on the 750i xDrive model. The German tuning company has a long history of tinkering with BMWs, and its latest effort certainly doesn’t appear to disappoint.

As a start, the 4.4 litre twin-turbo V8 now deliver 608 PS and 800 Nm of torque, allowing it to accelerate from 0-100 km/h in 3.6 seconds, and hit a top speed of 330 km/h. For reference, the standard 750i xDrive has 530 PS and 750 Nm, with a century sprint time of four seconds.

Important upgrades include larger impellers on the exhaust side of the turbochargers, which now measure 54 mm in diameter instead of the default 50 mm. There’s also a new engine management software, the latter allowing peak torque to arrive sooner from 2,000 rpm instead of the previous 3,000 rpm.

The optimised cooling system now comes with high-volume coolers, while the intercoolers comprise an indirect air to water to air set-up to allow for shorter air intake paths. There are even additional external water coolers and a transmission oil cooler to cope with high-demand situations.

Meanwhile, the eight-speed automatic transmission has been strengthened and receives Alpina’s custom software to better work with the more powerful V8. Along with closer gear ratios, the company promises quicker shift times over the previous B7. Even the xDrive all-wheel drive system comes with Alpina calibration.

On the exterior, you’ll find a new front bumper with functional air intakes and the Alpina script in the middle. Together with a small rear spoiler, these items help prevent lift for better high-speed stability.

Other add-ons include an Alpina stainless steel sports exhaust system with two elliptical twin tailpipes, and a set of 20-inch wheels (21-inch optional) shod with Michelin performance tyres. Bringing the car to a stop is now handled by an updated braking system with brake-by-wire tech and larger discs at the rear axle.

Alpina also focused on increasing comfort inside the cabin thanks to new shielding in the rear wheel arches and extra insulation in the B-pillars. Even the glass used for the windscreen and windows are five mm thicker than stock.
