2019 Mercedes-Benz CLS VS 2018 BMW 6-Series

There’s a class of large luxury sedans that caters to the demands of a loyal fan base and the 2019 models of both Mercedes-Benz and BMW deliver. We’re honing our razor sharp focus on the 2019 Mercedes-Benz CLS vs 2018 BMW 6-Series, to task ourselves with the impossible chore of picking a winner between the two. Sure it’s a tough job but someone’s got to do it and we’re up for the challenge. Enjoy this comparison of the 2019 Mercedes-Benz CLS vs 2018 BMW 6-Series. We’ll get started by approaching the performance of the Mercedes-Benz and the BMW side-by-side.

2019 Mercedes-Benz CLS vs. 2018 BMW 6-Series: Performance

The redesigned 2019 Mercedes-Benz CLS rides smoothly and makes a great cruising vehicle. It handles well and gets ample power from either of its turbocharged six-cylinder engines. The CLS 450 features a turbocharged 3.0-liter six-cylinder engine that puts out 362 horsepower. It also has an EQ Boost mild hybrid function that activates automatically and can add 21 horsepower (and 184 pound-feet of torque) over short periods. This engine delivers power in a smooth, linear fashion and never feels weak. The EQ Boost is a pleasant addition, making the engine feel livelier. According to EPA estimates, the CLS gets 24 mpg in the city and 31 mpg on the highway with its base engine. Those are some of the best ratings in the class.

There are four engines to choose from in the 2018 BMW 6 Series. The base engine is adequate, though unimpressive, and the most fuel-efficient. The 6 Series’ ride is comfortable, and the car is solid but not spectacular when it comes to handling curvy roads. The base 6 Series (the 640i) features a turbocharged 3.0-liter six-cylinder engine that puts out 315 horsepower. This is the weakest engine in the lineup. It earns an EPA-estimated 20 mpg in the city and 29 mpg on the highway. The only knock against the base engine is that the acceleration feels a bit slower compared to some rival cars. This large sedan has sharp steering and decent handling ability, but it doesn’t have the same athletic feel that you get from many other BMW vehicles.

2019 Mercedes-Benz CLS vs. 2018 BMW 6-Series: Feature Comparison

The 2019 Mercedes-Benz CLS looks modern and stylish inside following its redesign, with top-notch materials quality. Both rows of seats are comfortable. There’s plenty of available technology, and a user-friendly infotainment system comes standard. The CLS comes standard with the COMMAND® infotainment system that includes a 12.3-inch display screen and a touchpad controller that gives haptic and acoustic feedback. Available features include Thermotronic (GPS-linked) automatic climate control, Mercedes-Benz In-Car-Office, Mercedes-Benz Link smartphone connectivity, wireless device charging, a Burmester audio system, and Car-to-X communication. Beyond the infotainment system, the CLS offers a plethora of useful and cutting-edge technology. At the top of the list is Car-to-X communication, which allows all cars equipped with this technology to communicate with each other about hazardous on-road situations, allowing you to potentially avoid accidents and other dangers.

The 2018 BMW 6 Series has an extremely well-built cabin, as do many other cars in the class. The front seats are outstanding, but the rear seats have some room for improvement – namely, adding more room. The 6 Series comes standard with dual-zone automatic climate control, HD Radio, satellite radio, *Bluetooth®, a USB port, wireless phone charging, a Wi-Fi hot spot, and BMW’s iDrive infotainment system with a 10.2-inch display screen and navigation. Standard driver assistance features include adaptive cruise control, front and rear parking sensors, and a rearview camera. While the 6 Series offers a slew of active safety features, other cars in the class offer just as many or more (such as driver drowsiness monitoring) and cost less. The iDrive infotainment system is responsive and has a straightforward interface. The iDrive controller has a slight learning curve to it, but once you get the hang of it, it’s just as user-friendly as the rest of the system.
*Bluetooth® is a registered mark Bluetooth® SIG, Inc.

2019 Mercedes-Benz CLS vs. 2018 BMW 6-Series: Overall Comparison

Mercedes-Benz redesigned the CLS for the 2019 model year, and it sees plenty of changes. The 2019 model features a revamped trim lineup and replaces the prior generation’s twin-turbo V8s with six-cylinder engines. The new engines are more efficient thanks to the new mild hybrid technology. Inside, the CLS boasts an attractive, posh interior and offers a lengthy list of features, including many driver assistance options. The seats are comfortable and supportive as well. The CLS lives up to its luxury billing by providing a cushioned ride and a chic, well-built interior. There are lots of reasons to like this Mercedes-Benz, and that’s why it finishes in the top half of luxury large car rankings.

The 2018 BMW 6 Series is unquestionably a good car, but it shouldn’t be at the top of your wish list; there are better options in this class, such as the 2018 Mercedes-Benz CLS. The 6 Series delivers a good blend of performance and interior quality, but so do many class rivals. Convertible 6 Series models seat four. Gran Coupe (sedan) models seat five people. The rear middle seat is pretty worthless though, so it practically only seats four. Many competitors have better performance ratings, nicer cabins, or offer features the 6 Series doesn’t. Additionally, the BMW costs more than nearly every rival.
