We love these classic, straight-to-the-point, no-nonsense comparison tests between two cars that are so similar on the surface, one would have a hard time telling them apart. The cars in question here are the Alpina B6 bi-turbo and the BMW M6. And the benefit of this test is that it’ll reveal to you which is the best 6 Series-based high-performance Gran Coupe for your money.
Alright then, let’s hit it and join Motor Trend Senior Features Editors Jason Cammisa and Jonny Lieberman as they have a lot of fun, sorry, do a lot of testing and analyzing and hard work to know for sure if Alpina B6 is superior to the BMW M6 or what. It’s a rotten job, but somebody’s gotta do it, ya know?
