Spied: Alpina B4

Alpina’s B4 has been caught testing ahead of next year’s release and is clearly spotted sporting Alpina’s traditional multi-spoke wheels, blue brake calipers and quad-outlet exhaust system.

The body appears to be a production 4-series coupe, but we expect the Alpina B4 to be equipped with the same engine fitted to the B3– a twin-turbo straight-six 3.0-liter engine delivering 410 HP and 442 lb-ft of torque. Not too shabby.

The Alpina will probably bow at next year’s Geneva motor show (March 2014) and will likely have an AWD option.
