Wish BMW built a high-performance X7 M to battle the Mercedes-AMG GLS63? Well, the fresh-faced Alpina XB7 might just be the answer, boasting 457 kW from its twin-turbo V8.

Yes, the Buchloe-based BMW specialist has whipped the covers off its new XB7, which is based on the X7 M50i xDrive variant. The twin-turbo 4,4-litre V8’s peak outputs have been hiked from the standard 390 kW and 750 N.m to a healthier 457 kW and 800 N.m.

Despite tipping the scales at a hefty 2 655 kg, Alpina says the XB7 will hit 100 km/h from standstill in 4,2 seconds (and complete the 0-200 km/h dash in 14,9 seconds), which makes it around half a second quicker to three figures than the X7 M50i. The mammoth SUV tops out at 290 km/h in XB7 guise, while the ZF-sourced eight-speed automatic transmission has been suitably upgraded to handle the extra oomph.

Alpina has, of course, implemented all manner of other updates, too, including the fitment of its own sports suspension with two-axle air springs and featuring new dome-bulkhead and reinforced torsion struts.

The company furthermore offers 20-spoke alloy wheels measuring up to 23 inches in diameter, each wrapped in Pirelli rubber. A subtle body kit is also part of the package, with the rear apron framing the tailpipes of an Alpina sport exhaust system.

Inside, the firm has fitted items such as an Alpina steering wheel, a branded crystal gearknob and fresh leather upholstery. Naturally, it offers all sorts of customisation options.
