Mercedes-Benz CLS Coupe PERFORMANCE Performance Icon

2021 Mercedes-Benz CLS Coupe performance

Straight six with an electrifying twist.

A 362-hp turbo inline-6 teams tradition with technology. It's electrified with a 48-volt Integrated Starter-Generator that can seamlessly add up to 21 hp yet allow fuel-free coasting and lower emissions.

2021 Mercedes-Benz CLS Coupe performance

Power in all the right places.

The CLS 450 4MATIC sends torque to the wheels that can use it best. Light, efficient 4MATIC® adds all-wheel driving confidence on slippery roads, heightens fun in dry corners, and even quickens takeoffs.

Nine speeds with know-how.

With nine speeds and shift paddles, the advanced 9G-TRONIC automatic transmission is flexible, decisive, and adaptable. The multiple modes of DYNAMIC SELECT let you fine-tune the driving character of your CLS.

Hugs the road, embraces change.

The lowered multilink suspension's selective damping can firm up in corners, relax to tame rough roads. Optional self-leveling AIR BODY CONTROL adapts to roads, loads, and the modes of DYNAMIC SELECT.

EQ Boost Integrated Starter-Generator

Electrifying the inline-6 gasoline engine is an innovative Integrated Starter-Generator. It teams with a 48-volt lithium-ion battery and power supply for formerly belt-driven components like the water pump and air-conditioning compressor. These advancements help reduce weight and enhance underhood packaging. In addition to boosting power and torque for immediate response, EQ Boost offers a substantial reduction in fuel consumption.

ECO Start/Stop system

An ECO Start/Stop system automatically shuts off the engine at stoplights and other idle situations, to save fuel and reduce emissions. As soon as the driver lifts off the brake, the engine instantly restarts, for immediate acceleration response. Thanks to the Integrated Starter-Generator, restarts are even more seamless and instant. The ECO Start/Stop system can also be shut off by the driver at any time.

Evolution of a design trendsetter

The pioneering "four-door coupe" design of the CLS, with its arching roof and tensed muscle, inspired even plain sedans to become more sensuous. For its third generation, the CLS has rewritten its signature with smooth strokes: freshly clean and free of flourishes. It's aerodynamically refined to evade the wind, but styled to capture admiring eyes. From its subtle forward-leaning grille and twin-power-dome hood to its wide taillamps, it advances timelessness into the future, again.

Four-door coupe design

The tensed arch of its profile has become almost iconic, but it's the details that continue to make the CLS a style leader born of brilliant engineering. Its frameless side glass adds to its sleekness, yet advanced sealing and rigid bodywork assure its visual rush is delivered in a hush. Distinctive wraparound headlamps and taillamps integrate 100% LED technology. And its standard 19-inch wheels and wide diamond-block grille assert the athleticism that characterizes the CLS in motion.

AMG body styling

Bold and muscular yet flowing, AMG lower bodywork enhances both aesthetics and aerodynamics. The deep front apron features large air intakes with horizontal strakes. Flared side sills bridge the wheel arches and visually hug the road, while the rear valance outlines the tailpipes and central diffuser insert with a chrome accent.

Say what you want: Your CLS responds.

"Hey, Mercedes, it's cold in here." "I need a coffee." The Mercedes-Benz User Experience (MBUX) lets you control many cabin features by talking. Among them is MB Navigation, available with new tech that can also overlay instructions on live video of a turn.

Power front seats with memory

Power front seats feature intuitive, seat-shaped controls on the door, plus a 4-way power lumbar support. To set and save your ideal driving position, a memory system for each front seat recalls three stored positions for the seat, plus the positions of the 4-way power steering column and side mirrors for the driver.

Optional Active multicontour front seats with massage

Pneumatically adjustable lumbar, side and shoulder supports offer custom-tailored comfort. Active side bolsters can automatically increase lateral support in cornering maneuvers, or even in the event of a potential accident. Eight massage programs can soothe and rejuvenate your back and shoulders, including two spa-like "hot stone" massages, plus an "active workout" program to help strengthen your back and leg muscles.

Dual-zone automatic climate control

More brilliant by degrees.

The CLS pioneered adaptive LED headlamps for all cars years ago. Now they're available with Ultra Wide Highbeams that can adapt to corners and other cars, while illuminating more of the roadsides.

Reaches farther, reacts faster.

"Car-to-X" technology lets your CLS communicate with a central hub to report and receive updates about driving conditions beyond your line of sight. If PRE-SAFE® Sound detects an impending collision, it can act to pre-trigger your ears' natural defense against loud noises.

Active Brake Assist

Radar-based technology can alert you if you're approaching a vehicle ahead, or even some stationary objects, at a speed and distance that suggest a collision is likely. As soon as you start to brake, it can automatically provide an appropriate level of braking to help prevent a collision or reduce its severity. If you fail to respond, it can also initiate braking automatically at a range of driving speeds. The system can also detect and react to crossing pedestrians at typical city speeds.

The first system of its kind, ATTENTION ASSIST® continuously monitors up to 70 parameters of driving behavior, and can automatically alert the driver with both visual and audible warnings if it detects signs of drowsiness on long trips. With enhanced sensitivity, the system can also help detect drivers who begin their trip drowsy, and offer more useful information to drivers along their journey via a dashboard display.
