The new unofficial Alpina B3 Biturbo seems to be coming to the streets soon.
There's not a lot of info on this car, but we do have some specifications!
The B3 Biturbo makes use of BMW's twin-turbo 3.0l inline six, cranking the output up to 272kW (365 HP) and 499Nm (368 lb.-ft) of torque.
The four exhaust tips would indicate that spent fuel will be traveling through a revised exhaust system and judging by the gains made by other tuning companies, we'd expect a thorough reworking of the ECU's fuel and boost parameters.
