Comparison: 2014 BMW M6 vs. 2014 Audi RS7

    These two "four-door coupes" are extremely similar, with massively powerful V8 engines and four seats, along with the annoying "four-door coupe" title, which translated into actual English, means a sedan with a coupe silhouette. Sadly, they also have massive prices, both starting at over $100,000. But which uber-fast German sedan is the best?

2. Audi RS7

    The Audi A7 and S7 are two of my favorite cars, but for some reason, I didn't really squeal with joy when those maniacs at Quattro GMBH released the RS7. I don't know why, I just can't find something I really like about the RS7. I mean, they have replaced the subdued and understated grilles (which looked awesome) with some big hexagonal grilles that say the RS7 logo so everyone will know that you have spent much more money than the guy with the A7, which is a little obnoxious for my taste. But the engine is wonderful, maybe even better than the M6's. It is a twin-turbocharged 4.0 liter V8 which is the same engine as the one in the S8. It produces 560 hp and 516 pound-feet of torque, which is evenly distributed to all four wheels, thanks to signature Quattro AWD. The interior is practical and stylish, yet remaining practical and functional. I like the A7 and S7, I just don't like the flashiness of the RS7.

1. BMW M6

    Annoyingly, the 2011 M5 was a massive disappointment, with so-so steering, relatively slow acceleration, and somewhat poor driving dynamics. But the engine was great, with 560 hp and 500 pound-feet of torque. Those figures help the car go to 60 mph in 3.9 seconds. That same year, BMW released the second-gen 6-series. A year after, they released the 6-series Gran Coupe, which was targeted at the Mercedes-Benz CLS-Class, the Audi A7, and the Porsche Panemera. Alongside the regular 640i and 650i Gran Coupe, they released the M6 Gran Coupe, and it is spectacular. It has the same 560-hp twin-turbo 4.4 liter V8 as the M5, which works wonderfully in the 6-series, which it should, considering that the 6-series is a 5-series underneath the sportier body panels. The interior is simple, but still nice enough to be worth $100,000, thanks to aerodynamic styling, carbon-fiber trim, and black Nappa perforated leather. Even though the M5 isn't the best, the M6 is still an amazing car.
