Mercedes Benz AMG CLS63 vs Audi RS7
Both these cars are luxury sedans shaped in a Coupe-like fashion. However, in terms of engine capacity and fuel economy, the Mercedes pulls ahead of the Audi. The RS7 has phenomenally good interior and cargo space though, much better than the CLS. Also, considering the performance, the Audi seems to be better of the two.
Mercedes Benz AMG CLS63 vs Mercedes Benz AMG E63
The recently released E63 proves to be a tough competitor for the Mercedes AMG 63. The slightly lower price tag of the E63 is accompanied by a slightly smaller length and a non-unique body-style (there is wagon version of the E-class AMG, which is actually the one we would prefer over any of these other cars- Ed). In terms of engine and performance, you will be hard pressed to find any difference between the two. Moreover, the CLS is based on the old E-type class of vehicles and the E63 provides a new taste with a blend of new technologies into it, which undoubtedly makes it the better choice.
Mercedes Benz AMG CLS63 vs BMW M6 Gran Coupe
Though, both the cars prove to be similar, each has something different to offer. Both are V8 powered 4-door Coupe-style sedans, but the difference lies in their wheel drive configuration. The Mercedes is a bit more agile than the BMW, with the former reaching 100 kph in 0.5 seconds faster than the BMW. The BMW offers far more safety features though, and considering these aspects, the BMW gets the nod as the better car among the two.
