Alpina has quietly upgraded the B5 BiTurbo. While there doesn't appear to be any styling changes, the model
benefits from a revised tuning package which enables the twin-turbo
4.4-liter V8 to produce 540 PS (397 kW / 533 hp) and 730 Nm (538 lb-ft)
of torque - an increase of 33 PS (24 kW / 32 hp) and 30 Nm (22 lb-ft).
This enables the sedan to accelerate from 0-100 km/h in 4.5 seconds (an
improvement of 0.2 seconds) and hit a top speed of 319 km/h (198 mph) -
an increase of 12 km/h (7 mph). In terms of efficiency, owners can expect to average 10.5 L/100km (26.9 mpg UK / 22.4 mpg US) with CO2 emissions of 244 g/km.
