2018 Mercedes-Benz CLS Class vs. Its Competition

2018 Mercedes-Benz CLS-Class (CLS 550)
Martin Padgett Martin Padgett Editorial Director

The Mercedes-Benz CLS-Class helped define the segment it dominates.

As Mercedes prepares a new generation, we’d offer some newer rivals if the CLS sounds like the right car.

The BMW 6-Series Gran Coupe is the logical competitor and is a very good car—especially in M6 form.

The Jaguar XF was new last year, although we think its stiffer ride and more spartan interior are missed opportunities.

The Porsche Panamera is all new this year and is exciting, whether it’s in 4S trim or in hyper-pricey turbo hybrid form.

The Audi A7 is a worthy competitor and is one of our highest rated cars for its supreme performance and good looks, but it too is due for a reboot.

The CTS is interesting—especially in CTS-V form—because of its no-holds-barred approach to the segment.
