At the 2013 Detroit Auto Show, BMW debuted the first M6 model with four-doors. The BMW M6 Gran Coupe goes on sale this May and will compete in the four-door coupe segment with similar offerings from Mercedes-Benz and Audi.

Just recently Audi has also previewed a new, super sporty model in the RS line. The new Audi RS7 Sportback shares its drivetrain with the Audi RS6 Avant and has similar tech specs as the M6.

Both cars run on a V8 biturbo engine producing 560 horsepower and a top speed of 305 km/h. The M6 GC also produces 502 lb-ft of torque while the RS7 outputs 553 lb-ft of torque.


Audi stays true to its DNA and the RS7 Sportback sends power to the wheels via the quattro system. The better traction and slightly more powerful engine allows the RS7 to run from 0 to 62 mph in 3.9 seconds, two tenths of a second faster than the M6 Gran Coupe.

Since we are not able to compare the performance of the two cars in real life, yet, we decided to offer our usual photo comparison between these two amazing automobiles. Let’s have a look at the styling of the two and share with us your comments in the section below.
