BMW/ALPINA B6 BITURBO LCI F1x_F06
The B6 is based on the 650i and uses a modified version of its N63 twin-turbocharged V8 engine designated the M2/1. The engine was modified by the addition of new turbochargers with modified exhaust turbines, a BOSCH MEVD 17.2.H ECU, new MAHLE pistons and a larger intercooler. These modifications allowed the engine to generate 540 PS (397 kW; 533 hp) and 700 N⋅m (516 lb⋅ft) of torque (the B6 convertible’s engine generated a total of 507 PS (373 kW; 500 hp)). The engine is mated to an 8-speed ZF automatic transmission with optional limited slip differential and a manual shifting mode called the Sport Shift mode which allows the driver to change gears via buttons located on the back of the steering wheel.
The exhaust system is a titanium unit from Akrapovic with quad-exhaust tips and electronically controlled bypass valves. The B6 has an aerodynamic kit that includes a carbon-fibre front spoiler with an integrated front splitter along with an integrated NACA brake cooling duct and a rear lip spoiler and a rear diffuser.
The car comes with 20-inch Alpina classic multi-spoke alloy wheels wrapped in Michelin Pilot Sport tyres measuring 8.5 x 20 255/35 ZR20 at the front and 10 x 20 295/30 ZR20 at the rear.
The suspension system consists of electronically adjustable dampers (called Drive Performance) and active roll stabilisation (called Dynamic Drive) with Alpina specific software to control the system. The car has four driving modes, “sports”, “sports +”, “comfort” and “eco”.
The car has Lavalina leather interior upholstery and myrtle wood trim as standard. The interior has Alpina logos and emblems throughout along with illuminated door sills, a panoramic roof, Alpina gauges, adjustable vented sports seats, heated rear seats, BMW driver assistance plus including active blind spot detection and a sports steering wheel. Alpina’s customisation programme for the interior was exclusive to Europe only.
The B6 coupé and convertible came with rear-wheel-drive drive train while the later introduced gran coupe had all-wheel-drive drive train.
