The 2011 BMW Alpina B7 xDrive is recognizable by its control of the steering wheel in leather, the signature of twenty Alpina wheels, exterior aesthetic improvements, and some interior trim pieces. B7, but goes far beyond aesthetics. The advantages of the chassis brakes shorter and stiffer springs, bigger, wider tires, and alignment checked active dampers. Under the hood, supercharged 4.4-liter, twin-turbo V-8 BMW builds a new block, heads, turbochargers and intercoolers, beating out 400 hp and 450 Nm to 500 horsepower and 516 lb-ft.
With the active dampers set to comfort or normal mode, the B7 is blowing it in pristine isolation, damping road imperfections and block unwanted noise as competent as the standard 7-series. Tap the rocker switch for sport or sport-plus mode, and the B7 is a sharper direct nature.
If you expect performance, but the Alpina’s addition of 100 hp seems a dubious improvement. The new turbocharger with larger compressor wheels have significantly more delay than the standard BMW units. And since the standard 400 hp little slow, the trade-off between power and responsiveness moved in the wrong direction here, in my opinion.
