Buchloe-based company Alpina has reworked its B5 Biturbo program for 2012, providing it with the chops to do battle with BMW’s 412 kW (560 hp) F10M M5 model.
Initially developing 378 kW (507 hp) and 700 Nm (516 lb/ft) of torque from its twin-turbocharged 4.4 V8 engine, Alpina turns the wick up to release 397 kW (540 hp) and 730 Nm (538 lb/ft). Feeding its power to the road via a modified 8-speed automatic transmission the B5 Biturbo now hits 100 km/h (62 mph) in just 4.5 Seconds (down from 4.7 S) and enjoys a top speed of 319 km/h (198 mph) – up from 308 km/h (191 mph), while its fuel economy is 10.5 litres/100 km on the combined cycle.
