The Alpina B7 (F01) is the fourth generation of the high-performance BMW 7 Series manufactured by Alpina from 2011 until 2015. Based on the BMW 7 Series (F01), the car was introduced to the public at the 2010 Chicago Auto Show and was available in normal and long-wheelbase versions, with xDrive or rear-wheel drive. The B7's engine was hand-built at the Alpina factory at Buchloe and then sent to the BMW factory in Dingolfing to be put into the body shell. The car was painted and initially assembled at the Dingolfing plant and was then sent back to Alpina for final assembly. It was the second Alpina B7 to be offered in North America, with 1,740 examples imported and sold in the United States.[1]
Specifications
The B7 is based on the BMW 750i and the 750Li and uses a modified version of its 4.4-litre N63 twin-turbocharged V8 engine. The modifications include large 44 mm Honeywell turbochargers, reinforced cylinder heads, NGK spark plugs, high strength MAHLE pistons and an Alpina specific ECU. The maximum boost pressure of the turbochargers is increased to 14.5 psi. These modifications allow the engine to generate a power output of 507 PS at 5,500 rpm and 516 lbft of torque. The maximum torque is generated at 3,000 rpm, 1,250 rpm less than the previous model. To cope with the extra heat from the engine, an additional radiator, external engine and transmission oil-coolers, a high performance 1,000 watt fan (shared with the 760i) and larger intercoolers with large diameter water lines were installed.
