A special tuned version of the company’s Gran Coupe tourer will be making its global debut at the New York International Auto Show in April.

Just as Mercedes Benz has AMG — its in-house mad mechanical scientists that can take an already potent car and make it ferocious — BMW has ALPINA, and their latest co-creation, the BMW Alpina B6 Gran Coupe, will be going on sale in April in the US for $118,225.

The 6-Series Gran Coupe is already a great car. Elegant styling, a wonderful engine, excellent levels of comfort and every driver aid imaginable.

However, in Alpina form the powerplant is upgraded to a bi-turbo V8 and that means a 0-100km/h (62mph) time of only 3.7 seconds, a top speed of 198mph (320km/h) and 540hp to play with. The car also gets an eight-speed sports automatic gearbox and BMW’s xDrive all-wheel drive system to keep everything under control, no matter how hard the car is pushed.

But the tuning doesn’t stop there, the car also gets an Alpina exhaust system and to ensure that it really stands out from ordinary 6-Series models, special 21-inch wheels and a different aerodynamics package.

Inside, the improvements continue with Lavalina leather and a choice of Myrtle wood or Piano Black trim finish. But of course, that’s just the start. Customers can treat the car’s interior and exterior as blank canvases and simply ask Alpina to make it happen.

The New York International Auto Show officially starts on April 18.
