Are you looking for a luxury car that breaks away from the traditional mold? The 2021 Mercedes-benz Cls-class could be your answer. This coupe-like sedan, based on the esteemed Mercedes-Benz E-Class, offers a unique fastback roofline and sporty appeal, setting it apart from more conventional luxury sedans. While it might compromise slightly on rear headroom and practicality compared to its E-Class sibling, the CLS-Class rewards drivers with captivating aesthetics and a dynamic driving experience.
The Cost of Elegance: Fuel Economy of the 2021 CLS-Class
To give you an idea of running costs, let’s consider the fuel consumption of the 2021 Mercedes-Benz CLS-Class CLS 450 Sedan. Based on North Dakota energy prices of $3.85 per gallon for premium unleaded and driving 15,000 miles annually (55% city, 45% highway), the estimated monthly fuel cost is around $184. This is comparable to the average large car, estimated at $195 per month.
The 2021 model year is significant as it precedes the refreshed 2022 version. Mercedes-Benz enhanced the 2021 CLS-Class by making the advanced MBUX infotainment system standard. This technological upgrade gives it a competitive edge against rivals like the Audi A7, BMW 8 Series Gran Coupe, and Porsche Panamera in the tech department. Let’s delve deeper into what makes the 2021 Mercedes-Benz CLS-Class a compelling choice in our comprehensive expert review.

Performance: Effortless Power and Refinement
8.5/10
How does the 2021 Mercedes-Benz CLS-Class perform on the road? It excels as a well-rounded sport luxury sedan, striking a balance between potent power and exceptional refinement. Power delivery is seamless, devoid of any flat spots. Our tests of the AMG 53 variant clocked a 0-60 mph acceleration in just 4.3 seconds – truly impressive for its class. The CLS-Class exhibits confident and secure handling, offering a more engaging driving experience compared to lower E-Class trims. The precise steering provides excellent feedback, ensuring confident control. Whether navigating city streets or cruising on the highway, the CLS-Class delivers a refined and sporty driving feel.
Comfort: Serene and Supportive on Every Journey
9/10
What about the comfort of the 2021 Mercedes-Benz CLS-Class? It excels in long-distance comfort thanks to minimal noise intrusion, supremely comfortable seats, and a highly effective climate control system. The engine operates with remarkable smoothness. The front seats, upholstered in supple leather with firm padding, provide outstanding support and comfort even on extended drives. At highway speeds, the CLS-Class effectively isolates occupants from wind noise. Engine noise is minimal, with only a subtle growl audible during spirited acceleration. Engine vibrations are virtually non-existent. The only minor drawback is slightly noticeable tire noise on uneven road surfaces, which is a touch more pronounced than expected in a vehicle of this caliber.
Interior: Intuitive Design with a Touch of Style
8/10
Stepping inside the 2021 Mercedes-Benz CLS-Class, you’ll find an interior designed for intuitive interaction. The controls are user-friendly, featuring straightforward interfaces. While the infotainment screen menus might initially seem complex, their organization is logical. The multiple input methods for the infotainment system – including hard keys, a rotary knob, touchpad, steering wheel touch controls, and voice command – enhance ease of use. Front passengers enjoy ample elbow and legroom. However, the sloping roofline does slightly impact headroom, particularly for rear passengers, when compared to the more traditionally shaped E-Class sedan.
Technology: Cutting-Edge and Seamlessly Integrated
8.5/10
The 2021 Mercedes-Benz CLS-Class is packed with advanced technology. The large, high-resolution display screen is visually striking, and the MBUX infotainment system offers a wealth of features. The optional Burmester premium audio system delivers exceptional sound quality. Navigating the system using the rotary knob feels natural and effective, and the steering wheel touch controls become intuitive with a little practice. The array of driver-assistance features is extensive and operates seamlessly. Our test vehicle was equipped with the optional Driver Assistance package, encompassing virtually every imaginable assist feature, all meticulously calibrated with minimal false alerts.
Storage: Style Prioritizes Over Utilitarian Space
7.5/10
Practicality takes a slight backseat to style in the 2021 Mercedes-Benz CLS-Class when it comes to storage. The trunk offers less cargo space than the E-Class sedan and most other midsize luxury sedans. Nevertheless, it still provides enough room for weekend luggage. The 40/20/40-split folding rear seatbacks enhance versatility, ensuring decent practicality for a sedan primarily focused on aesthetic appeal. The cabin offers adequate small-item storage, including generously sized door pockets and a divided center console.
Fuel Economy: Efficient Performance
8/10
The AMG CLS 53 variant we tested achieved an EPA-estimated combined fuel economy of 23 mpg. This is considered above average for a performance-oriented luxury sedan, making the 2021 Mercedes-Benz CLS-Class a relatively fuel-efficient choice in its segment.
Value: Exclusivity Comes at a Premium
8/10
The 2021 Mercedes-Benz CLS-Class exudes impeccable build quality and a sense of exclusivity. It looks and feels special, justifying its price point for those who appreciate its unique blend of style and performance. While not an inexpensive vehicle, owners will likely feel they receive commensurate value for their investment every time they get behind the wheel. However, it’s worth noting that the E-Class sedan presents a compelling alternative, offering similar features at a lower price and with more rear headroom.
Wildcard: Distinctive Appeal and Driving Delight
8.5/10
The 2021 Mercedes-Benz CLS-Class stands out with its abundant power and refined driving experience, solidifying its appeal. It exhibits impressive capabilities, even during spirited driving, while maintaining a composed demeanor. Its distinctive styling further enhances its desirability, setting it apart from the more conventional luxury sedan crowd.
