The CLS and the 6-Series BMW have four doors each, yet they are both considered coupes by their manufacturers. The coupe claim comes from the fact of the car's rear end. It curves down dramatically, shortening the length of the sedan. Although we don't necessarily agree with this designation, we can't help but appreciate the 2016 Mercedes-Benz CLS vs 2016 BMW 6-Series comparison because both vehicles offer incredible performance and luxury.
The 3.0L twin turbo 6-cyilinder engine is the new Chevy Big Block. It is perfectly balanced with the technology and power of the modern automobile, offering a compromise between fuel efficiency and power that everyone can get behind. Both of these cars feature this type of engine, pushing horsepower numbers north of 300, which is incredible considering both of these are base model trims.
The 640i and the CLS400 are very similar cars. Every time you find one advantage between the two, something else comes out of the woodwork to balance the equation. The 640i has an 8-speed transmission as a standard feature, but it is a heavier car and consequently has a slower 0-60 time. The 640i does get one more mile for every gallon on the highway, but this is hardly enough of a reason to influence a purchasing decision. Overall, the CLS comes with a lower price tag, has more horsepower, and weighs less. If you want to save money and go faster at the same time, the 2016 Mercedes-Benz CLS is the way to do it. Of course, each of these models has other trims that could be compared, but for the sake of simplicity, we focused on the base models because they are the most similar and the most popular.
