Even if rumors concerning the the 2011 BMW M5 are heating up, that hasn’t stopped BMW and Alpina from teasing the next performance model based on the new 2011 5 Series.
As such, the first sketch of the BMW Alpina B5 Bi-Turbo has been revealed, just as the model is preparing to make its official debut later this summer at the Goodwood Festival of Speed in the UK.
As you can tell by the name, the B5 will boast an upgraded twin-turbo engine, but we still don’t know the exact specifications. The design of the 2011 5 Series has received a few new touches, and the classic set of Alpina wheels are present.
The Alpina B5 Bi-Turbo, according to rumors, will also have a better fuel average, but we’re taking that part with a grain of salt.
