If you want the practicality of a Mercedes E-Class but prefer the sexy styling of a coupe, the CLS is the perfect car for you. Mercedes invented the four-door coupe segment with the CLS back in 2004 and the car is now in its third generation. The base 2019 CLS 450 starts at $69,200, which is around $10,000 more than the equivalent E-Class. For nearly $70,000, the CLS 450 is powered by a 3.0-liter inline-six engine producing 362 horsepower and 369 lb-ft of torque that goes out through a nine-speed automatic transmission.

This seems like an adequate amount of power for an elegant car like the CLS, but a recent trademark filing with the United States Patent and Trademark Office, which was uncovered by Motor1, shows plans for a slower, more affordable model.

The patent describes a CLS 300 model, which will likely use the same 2.0-liter turbocharged four-cylinder engine found in the E 300. In the E-Class, this engine develops 241 hp and 273 pound-feet of torque, so we assume it will produce identical numbers in the CLS. Like the CLS 450 models, power still goes out through a nine-speed automatic to either rear-wheel-drive or 4Matic all-wheel-drive.

The CLS 300 will be slower than its six-cylinder counterpart (it'll take around 6.2 seconds to hit 60 mph) but it will come at a lower price. If the CLS 300 and CLS 450 are priced comparably to the E 300 and E 450, we would expect the CLS 300 to start at around $65,000 with 4Matic AWD or around $62,000 with RWD.

We aren't sure when the CLS 300 will actually arrive on the market, but since this is only a new engine and not an entirely new car, it shouldn't take long if the trademark filing turns out to be indicative of anything.
