- Powertrain warranty covers four years or 50,000 miles

Safety and Driver-Assistance Features
The 2021 CLS53 hasn’t been crash tested by the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS). Every comes with standard safety features that include automated emergency braking and blind-spot monitoring. Additional driver-assistance aids are included in the Driver Assistance package, among them are Level 2 semi-autonomous features, such as adaptive cruise control with stop-and-go technology and lane-change assist (which can steer into the next lane for you). Key safety features include:
- Standard forward-collision warning and automated emergency braking
- Standard blind-spot monitoring
- Available adaptive cruise control and lane-keeping assist
With a sleek and distinct design as well as a host of AMG-specific enhancements, the 2021 CLS53 is a four-door coupe that is as elegant as it is athletic. Power comes from a silken, turbocharged, 429-hp, straight-six engine that’s mated to an astute automatic transmission and standard all-wheel drive. The CLS53 is nearly mechanically identical to the Mercedes-AMG E53 sedan, but due to its racier styling its back seat and trunk are less accommodating. Its cabin boasts cutting-edge technology that effortlessly mingles with the assortment of upscale materials and finishes. While the CLS53 is better at long-distance cruising than backroad thrills, it has the ability to engage you when you activate its sportiest performance settings. The Audi S7 is both more exciting and practical, but the CLS53 costs less and looks more upscale.
Pricing and Which One to Buy
The 2021 CLS53 won’t be on sale until later this year, and Mercedes hasn’t said how much it will cost. However, we don’t expect its starting price to significantly increase. Since there’s only one model to choose from, our recommendation focuses on our favorite options. We’d upgrade the standard 19-inch rims to 20-inchers for a bolder appearance and add the Exterior Lighting package for its automatic high-beams and more luminous headlights. Inside, we’d increase the sedan’s luxury quotient by selecting the nappa leathery upholstery, the Warmth and Comfort package (heated steering wheel, front armrests, and rapid heating for the front-seat cushions), and add the massaging front seats too. The head-up display, three-zone climate control, soft-close doors, ventilated front seats, and the Acoustic Comfort package (laminated glass that keeps the cabin cooler and quieter) are all individual options that maximize the CLS53’s upscale aura. Finally, we’d select the AMG performance exhaust for its burlier soundtrack and take the Driver Assistance package for its suite of safety features that include adaptive cruise control and lane-keeping assist, among others.
Infotainment and Connectivity
Every 2021 CLS53 features the Mercedes-Benz User Experience (MBUX) infotainment system, which includes a voice-activated assistant and myriad input methods. Along with touch-sensitive pads on the steering wheel as well as the center touchscreen, it can be manipulated through a large touchpad on the center console. MBUX comes with Android Auto and Apple CarPlay, built-in navigation, and three USB ports. Options include a head-up display and a Burmester surround-sound audio system. Another add-on is AMG Track Pace, which lets you store performance data from your vehicle in the infotainment interface when you’re driving on a road course.
What’s New for 2021?
For 2021, Mercedes installs an entirely new infotainment system in the CLS53. Called MBUX (short for Mercedes-Benz User Experience), the upgraded unit brings a new touchscreen and a responsive touchpad with haptic feedback. It also features a voice-activated assistant—think Amazon Alexa or Apple’s Siri—as well as innovative options. The latter includes navigation with augmented reality, which overlays guidance and other real-time information onto a live video feed of the road ahead that’s showing on the screen. The CLS53 also now has more advanced driver assists that can react to live-traffic data and stop the car from turning left if it detects oncoming traffic.
Interior, Comfort, and Cargo
Mercedes has a knack for integrating the latest technology into its interiors while preserving the old-world opulence that everyone expects in a luxury sedan from the brand. So it is with the CLS53. All the major displays are digital, including the instrument panel, which measures 12.3 inches, yet there’s a warmth to this four-door coupe’s cockpit that competitors can’t quite match. In the rear, the CLS53 feels more like a sedan than a coupe, with three-across seating and a 40/20/40-split folding rear seat. The sloped roofline reduces headroom for adults, however. Trunk capacity is only 12 cubic feet.
Engine, Transmission, and Performance
Every Mercedes-AMG CLS53 comes with a turbocharged and electrically supercharged 3.0-liter inline-six-cylinder engine with a 48-volt hybrid-assist system called EQ Boost, a nine-speed automatic transmission, and all-wheel drive. The engine is rated at 429 horsepower and 384 lb-ft of torque, with EQ Boost adding up to 21 horsepower and 184 lb-ft. The CLS53 we tested hit 60 mph in 4.0 seconds and covered the quarter-mile in 12.5 seconds at 111 mph. The inline-six is characterful and eager to rev, and the nine-speed delivers quick upshifts and satisfying downshifts. The AMG CLS53 is equipped with an air suspension and adaptive dampers as standard. This setup provides surefooted handling and an acceptable ride on most roads, but the CLS loses composure over bumps and can feel brittle over rough pavement. The similar E53 has slightly softer tuning and offers a more compliant ride as a result. We have no complaints about the CLS53’s electrically assisted steering, though. It’s direct and surprisingly rich in feedback.
