Mercedes-Benz CLS 63 AMG vs BMW M6 Gran Coupe vs Audi RS7
Penned by Michael Fink, the swooping design of the CLS was like nothing ever before in the Mercedes-Benz range, and its major success has prompted the arch enemies of the Stuttgart brand to develop rivals of their own.
First came Audi, who decided to make a spinoff for the “four door coupe” design, therefore creating the Audi A7 hatchback. BMW didn't took long and introduced a four-door version of the 6-Series called the Gran Coupe last year, even though technically the 5-Series was already a four-door base model for the 6-Series Coupe.
Meanwhile, the Mercedes-Benz CLS is now already at its second generation, with the C218, while its two main rivals are each starting to make a name of their own.
Each of the three has an even sportier version as a flagship model, and, coincidentally, all three are very similar in terms of power and performance characteristics, even though the S-Model version of the CLS 63 AMG is pretty much the grand daddy when it comes to power, torque and its official 3.6 seconds time required from 0 to 100 km/h (62 mph).
Americans from Car & Driver recently had a go in each of those versions, pitting the CLS 63 AMG S-Model against the BMW M6 Gran Coupe and the Audi RS7. While we don't necessarily agree with the top made by them, the comparison test is well worth the read.
