BMW has unveiled the 2013 ALPINA B7, ahead of its slated debut at the Pebble Beach Concours d'Elegance.

Based on the facelifted 7-Series, the model features more than 30 new parts including a revised front fascia with LED fog lights. There's also an upgraded interior with new upholstery choices and ceramic secondary controls.

Power comes from a twin-turbo 4.4-litre V8 engine that develops 540 bhp and 728 Nm of torque - an increase of 40 bhp and 30 Nm. It is connected to an eight-speed automatic transmission which enables the model to accelerate from 0-100 km/h in just 4.3 seconds and hit a top speed of up to 312 km/h.

The ALPINA B7 will go on sale beginning this August.
