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 5200 to 6250rpm, with a maximum torque of 730Nm from 2800 to 5000rpm. Two turbo-chargers, 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.
