Somewhat unique to the industry, the CLS Coupe and the 6-Series Gran Coupe have four doors, despite the coupe in their names. The reason for this designation is the way the roof meets the trunk, offering the sport of a coupe with the convenience of a sedan. With less trunk space and more room in the back seat, these two vehicles are perfect for growing families or track enthusiasts alike. When you put them head to head in a 2017 Mercedes-Benz CLS Coupe vs 2017 BMW 6-Series cage match, interesting conclusions arise that may affect your next vehicle purchase.
An overview of the specifications of each model will show you that the two vehicles were built for different purposes. Although both offer respected horsepower and efficiency measurements, the CLS is built for power and speed, whereas the 6-Series leans more towards efficiency. It is important to note, however, that the CLS used in this comparison is equipped with all-wheel drive. Since the BMW is not, it is a little more understandable why the CLS lacks in the economy department.
There are many different trims that come with the CLS and 6-Series badges, but the CLS 550 and the 640i are the most similar models between the two German manufacturers. The major difference between the two is the approach that was taken in the designing stages. Mercedes-Benz is well known for its biturbo V8 engines and BMW takes justified pride in its TwinPower technology, but the result of this incongruence is crucial.
If you are looking for a luxury 4-door coupe that gets the best gas mileage, the BMW might be an obvious choice for you. In every other category, however, the CLS has multiple advantages. It is more affordable, comes with more power, and provides the thrill of a biturbocharged V8 engine.
