  • Introduction

    In March 2009, at the Geneva motorshow, the B7 BiTurbo was introduced based on the F01 7-series.

    The LWB version of the B7 BiTurbo was introduced at the Tokyo Motorshow in October 2009. Interestingly, due to the global economic crisis Alpina was the only German manufacturer who attended this motorshow. The 4-wheel-drive Allrad version of the B7 BiTurbo was introduced at the 2010 Geneva motorshow.

    The LCI version of the B7 BiTurbo was introduced in late 2012. It encompassed significant changes to the drivetrain. The engine management computer was changed from Siemens MSD 85 to Bosch MEVD 17.2.8.

    Engine/Gearbox

    The F01 B7 BiTurbo engine is based on the 4,4 liter Twin Turbo engine from the 750i and not the H1 supercharged engine from the E65 B7, E60 B5 and E63 B6.

    The changes made to the 750i engine include modified turbochargers (in partnership with Garrett Honeywell), intercoolers and new pistons. The power output is 507 bhp and torque is 700 NM, available from 3000 rpm. The fuel consumption is 11,9 l/100 km according to Alpina.

    The LCI version of the B7 BiTurbo increased power to 540hp and 730Nm.

    As customary with previous 7-series, the B7 BiTurbo features a Switch-Tronic gearbox. Initially, the B7 BiTurbo was available with the 6-speed ZF 6HP26TÜ gearbox. The LCI version of the B7 BiTurbo featured the much faster 8-speed ZF 8HP70 gearbox.

    Suspension/Brakes/Wheels

    The brake discs measure 374 mm at front and 370 mm at rear, same as the E65 B7.

    The B7 BiTurbo is 15 mm lower at front and 10 mm lower at rear than a standard BMW 750i.

    The wheels feature an updated design of the classic Alpina wheels. The wheels are 21″ with 245/35 tires at front and 285/30 at rear.

    Interior/Exterior

    Inside the B7 BiTurbo is equipped with sport seats in Alpina design leather, new instruments with blue background and red needles, luxury wood “Myrtle”, a hand-stitched leather steering-wheel, Alpina floor mats, Alpina door sills and a silver-plated production plaque. The exterior changes are very subtle, front and rear spoiler lips are fitted. These make the car more stable at speed while maintaining a very low CW-value.

    The B7 BiTurbo also has two twin exhaust pipes, which are very easy to notice.

    Performance

    For the B7 BiTurbo, Alpina claimed 0-100 km/h time of 4,7 seconds and an electronically limited topspeed of 280 kph. After Michelin was able to provide suitable tires, the topspeed limiter was removed.

    The LCI version has a 0-100 km/h time of 4,6 seconds and a topspeed of 312 kph.
