Like the 'base' Alpina B7 BiTurbo, it too features a twin-turbo 4.4-liter V8 producing 507 horsepower and 516 lb-ft of peak torque thanks to the larger turbos and a new intercooler. Power is transferred to the rear wheels through a tweaked six-speed automatic transmission.
Other highlights include a subtle aero kit with front and rear aprons, and a discreet boot lid spoiler, plus a bespoke interior, 21-inch alloy wheels and a retuned suspension.
