2018 Mercedes-Benz CLS 550 Coupe vs 2018 BMW 6 Series Gran Turismo

The luxury coupe segment is highly popular and competitive. Drivers expect luxury coupes to deliver smooth, exhilarating performance and feature upscale styling and premium interiors. Two of the top luxury brands, Mercedes-Benz and BMW, each have their own flagship coupe model. Check out this 2018 CLS 550 Coupe vs 2018 6 Series Gran Turismo comparison to see how they stack up against each other.

Both the CLS 550 and the 6 Series Gran Turismo are competitively priced for their segment--yet the CLS 500's slightly higher MSRP indicates that it has more to offer under the hood and inside the cabin. The CLS 550 boasts a larger engine and a 9-speed transmission over the 6 Series Gran Turismo's 8-speed. Due to its larger powertrain, the CLS 550 Coupe delivers an incredible 67 more horsepower than the 6 Series and accelerates from 0-60 MPH .2 seconds faster. The 6 Series compromises its lack of power for better fuel efficiency than the CLS 550 Coupe--but it's not enough of a difference to make the sacrifice worth it.
