Alpina trotted out its upcoming B6 Gran Coupe for some Spring time testing and we've caught it fitted with Alpina front lip, trunk wing, wheels and exhaust system. The aero parts remain unpainted and no Alpina rear diffuser/bumper has yet been installed.
For an idea of what the specs may be for the B6 Gran Coupe, the
2013 Alpina B6 Coupe features 540hp / 730nm (538 lb-ft) torque, with a top speed of 334 km/h - based on BMW 4.4L V8 motor. How do those specs stack up against the M6 in the performance department? Check out the Sport Auto comparo results below.
