One of the biggest surprises on the German public roads this week was an Alpina version of the 2014 6-Series GranCoupe . As you can see, the model is wearing camouflage only in the parts rumored to be updated, because as usual, Alpina is preparing the biggest updates under the hood.
As you can see from these spy shots, Alpina will use a 650i version for its project. While in the standard version the 4.4-liter V-8 engine delivers a total of 450 horsepower, Alpina is rumored to add at least an extra 100 horsepower. We expect this extra power to significantly improve the car’s current 0 to 60 mph sprint time of 4.6 seconds.
Next to the engine upgrades, Alpina will also offer a few styling changes, an updated interior and.a new set of wheels, of course.
Expect the new BMW 6-Series Gran Coupe by Alpina to be unveiled in September at the 2013 Frankfurt Motor Show.
