The CLS-Class is offered in three models for 2016. The CLS400 features a 3.0L V6 that makes 329 horsepower and 354 pound-feet of torque. The CLS550 has a 402-horsepower 4.6L V8 with 443 pound-feet of torque, while the CLS63 S AMG boasts a 5.5L V8 with 577 horsepower and 590 pound-feet. Mercedes claims the AMG will do 0 to 60 mph in just 3.6 seconds. All three engines are twin-turbocharged and feature direct injection.
Both the CLS400 and CLS550 are standard in rear-wheel-drive, with 4MATIC all-wheel drive optional, while the CLS63 only comes with 4MATIC. A 7-speed automatic transmission is standard on the CLS400 and CLS63 S, while the CLS550 features a 9-speed automatic. The CLS63's gearbox differs from that of the other cars with an AMG multi-clutch transmission that uses a clutch instead of a torque converter for better responsiveness, quicker shifts and a more direct feel during high-performance driving. The CLS400 returns an EPA-estimated 24 mpg combined in rear-wheel-drive models and 22 mpg combined in 4MATIC all-wheel-drive models.
The CLS-Class is referred to as a coupe by Mercedes-Benz, and when viewed from a front or rear angle, it's easy to see why. The arched roofline and heavily sculpted flanks -- especially the accented rear wheel arches -- can make the CLS-Class look like a muscle car, while from the side or up close it becomes clear that this is a sedan with an actual trunk.
The CLS-Class is primarily stylish transport for two, with a smaller-than-usual backseat just large enough for two adults when needed. It's furnished with a truly high-end look and feel, including natural-grain leathers and real wood trim. Despite the CLS-Class' performance flavor, it includes a wide range of noise insulation and vibration damping. Nicely contoured front seats will provide great long-distance comfort, but the CLS63 upgrades to even more supportive sport seats plus more contoured rear seats. Active ventilated seats are available to keep occupants warm or cool and a driver's multi-contour seat inflates to provide special support as well as help hold the driver in place when cornering.
On the CLS63, many of the interior trims are upgraded. In addition to the sport seats, there are special AMG door sill panels and brushed stainless-steel pedals, along with expanded leather trim. There's also a special E-Select shift lever, as well as a "Race" mode that can record lap times.
Bi-xenon headlamps are standard on the CLS-Class, and they come supplemented with what Mercedes-Benz is calling the world's first active LED headlamps. The setup includes active-curve lamps that help illuminate up to 15 degrees into an upcoming corner, as well as lower-speed cornering lamps. The tail lamps also use LED lamps, and the headlights have an Adaptive Highbeam Assist feature that can detect traffic coming from ahead or behind. City dwellers might also find Parktronic useful; it uses sonar sensors to show nearby obstacles. Active Park Assist will actually steer the vehicle into a parking space at speeds below 7 mph.
All CLS-Class models include COMAND, the Mercedes-Benz screen-based interface, navigated by a rotary controller, to access audio, climate, and navigation functions. Also of note is the available Harman/Kardon Logic 7 surround-sound system, which has 14 speakers, a 610-watt amplifier and a subwoofer for a studio-quality experience.
Both of the CLS-Class models include electronic stability control, anti-lock brakes with Brake Assist, a Distronic Plus cruise control system that lets drivers follow at a safe distance, and a Pre-Safe emergency braking system that can spot slowdowns ahead and bring the car to a full stop. Attention Assist studies movements of the steering wheel to spot times when drivers might be falling asleep, sounding a chime and displaying a coffee-cup symbol. Rain-sensing wipers even feature a heated washing system and headlight cleaners.
I vividly remember the first time I saw the Mercedes-Benz Vision CLS concept car. It graced the December 2003 cover of Automobile Magazine alongside other iconic concepts from that year's Frankfurt Auto Show, but the Vision CLS was special. A near-production look at the first modern "four-door coupe," the Vision CLS was the genesis of a trend that truly disrupted the industry. For 10-year-old me, the gorgeous design was revolutionary.
Now, 19 years later, the CLS is nearing the end of its third generation, and while it's still beautiful, it's no longer the showstopping trendsetter it once was. Instead of putting a sparkle in my eye, the 2022 CLS450 just makes me sad.
That disappointment is in large part due to the CLS' styling. As I said, it's still a great looking car, but the proliferation of the four-door coupe-style roofline throughout every size and class of sedan makes the slippery shape less novel. It doesn't help that Mercedes' other four-door coupes, the CLA and AMG GT, look even better. The blacked-out trim from the $400 Night package and the nonmetallic Midnight Blue paint on my test car does the car no favors, and as part of the Manufaktur catalog, that shade costs $6,500. This third-gen model has always kind of looked like a bar of soap -- not always in a good way -- but at least gave it a more interesting front fascia and star-pattern grille.
One bright spot is the CLS' cabin, even though it's nearly identical to the E-Class. The pair of 12.3-inch screens features Mercedes' MBUX software, and while it's feeling a little old compared to the touchscreen setup in cars like the new C-Class, it's still a great system. Navigation comes standard, as do and . I love this CLS' combination of Sienna Brown leather and flowing lines of piano black trim (a $1,300 option), and as a whole, the interior feels well put together. There's definitely less headroom and legroom in the CLS compared to the E-Class, but I don't find it to be too cramped or claustrophobic.
The Good ~ Flashy interior ~ Fantastic powertrain
The Bad ~ Too-sedate styling ~ Rough ride ~ Very pricey
The Bottom Line The 2022 Mercedes-Benz CLS is a good car, but a far cry from the showstopping original.
Diesel Sprinters will soldier on, though, and an electric variant is also on the way.
Over 50 people are involved in the dozen-plus stages required to build this $3 million machine.
Customer deliveries will start before the end of this year.
We rounded up the best of the battery-powered cars just for you.
The EQB takes everything great about the GLB and adds an electric powertrain, which might make it even better than the original.
After two impressively long jaunts of increasing distance, Mercedes-Benz's rolling EV test bed proves it's not done quite yet.
Despite not riding on a dedicated EV platform, you'd have a hard time telling the EQB wasn't designed as an electric car from the start.
The efficiency tech in this car could very well end up in your next EV.
