The spy photos were snapped during a test run of the dubbed Alpina B6 model.

In a true traditional Alpina manner, the prototype was mounted atop some multi-spoke wheels. Camouflage can be seen on the front and rear spoilers, so we should expect them to get an update, too.

Of course, Alpina will not limit themselves at these minor visual tweaks, so most likely we will see on the B6 a new set of suspensions and brakes. Rumors also place a 100 Hp power increase beneath the hood. Considering that a standard 650i model will do 450 Hp and 650 Nm of torque, after Alpina is done, the total of 550 Hp will rival the numbers of the BMW M6.
