If you want a BMW tuned to deliver blistering speed, you don't even need to leave the dealership. Everyone knows that if you want a fast BMW, you buy an M. Or do you? The M division is not the only tuning company that builds a badass version of BMW models. Alpina has been around since 1965
, and has created some of the coolest BMWs over the past half century. The company even makes its own version of the 6 Series Gran Coupe
called the B6. Like the M6, the B6 has 600 horsepower, but it also has way more torque and an extra gear.
