As BMW doesn’t produce an M version for the X7, those looking for a performance version of the German automaker’s large SUV will have to look at the Alpina XB7.

The XB7 is powered by a 4.4-liter twin-turbocharged V8 pumping out 612 hp between 5,500 rpm and 6,600 rpm and 590 lb-ft (800 Nm) of torque from 2,000 to 5,000 rpm. This enables it to hit 60 mph (96 km/h) in 4.0 seconds, sprint down the quarter-mile in 12.6 seconds and reach a top speed of 180 mph (290 km/h).

Coupled to the 4.4-liter twin-turbo V8 is a ZF-sourced eight-speed automatic transmission that sends power through all four wheels. The SUV also features an electronically-variable active limited-slip differential on the rear axle that improves traction during dynamic driving by minimizing slip-induced losses and distributing torque in the most effective way possible.

Of course, it’s not just the powertrain that makes the XB7 special. As Doug DeMuro discovers, the interior is also extremely luxurious and the car he tested was equipped with captain’s chairs in the second row. Those sitting in the second row can also use the seat-mounted touchscreens to check out various things like the navigation system, enjoy various entertainment options, and adjust a host of settings, including the ambient lighting system.

Pricing for the Alpina XB7 starts from $141,300 in the States, not including delivery fees and taxes, with the model featured in Demuro’s review costing around $155,000.
