For ALPINA, a technology driven company, standstill is a foreign word. Since the introduction of the B7 Bi-Turbo, the engineers from Buchloe, Germany, have been continuously working on the details of the turbo charging and intercooler system. Consequently, the all-aluminium V8 power plant now produces 540hp (397kW) at a moderate 5500rpm, with a maximum torque of 700Nm from 3000rpm. Two turbo-chargers configured in parallel, each feeding one of the two cylinder banks, with specially developed large diameter exhaust-turbines allow this engine configuration to provide both exceptional power output and an abundance of torque over an especially broad rpm range while maintaining excellent throttle response at low rpm.
Direct injection and Double-VANOS contribute to the B6 Bi-Turbo’s class-leading consumption and emission figures: 10.5 (10.6) l/100km and 244 (247) g/km CO2, Combined cycle, measured according to ECE Norm (data for Convertible in brackets).
The intelligent coupling of state-of-the-art engine and transmission technologies give the B6 Bi-Turbo stunning performance figures: 0-100km/h in 4.4s (4.5s), and a top speed of 320 (317) km/h.
