Are traditional luxury cars too staid and dull for your taste? A good remedy is to consider a coupe-like sedan with a sporty fastback roofline. The Mercedes-Benz CLS started the trend nearly two decades ago, and it remains an excellent alternative to more conventional sedans. Based on the Mercedes E-Class, the CLS puts a trendy twist on luxury vehicles. Yes, you sacrifice some rear headspace and overall practicality, but it'll be worth it if you find the CLS' look appealing.

To keep the current offering relevant, Mercedes-Benz has updated the CLS to include the company's excellent MBUX infotainment system as standard this year. It's now armed with an advantage in the tech department over competitors including the Audi A7, BMW 8 Series Gran Coupe and Porsche Panamera. What else is there to like?

Performance
8.5/10How does the CLS-Class drive? The Mercedes-Benz CLS is a well-rounded sport luxury sedan that stands out both for its power and its extreme refinement. There are no flat spots in the power delivery. We tested the AMG 53 version and recorded a 0-60 mph time of 4.3 seconds, which is impressive.
The CLS' handling is capable and secure, and overall it's a more rewarding car to drive than the lower-trim E-Class sedans. Precise steering gives you a clear sense of the on-center position. Even if you're just cruising around town, the CLS provides a sporty and refined driving experience.
Comfort
9.0/10How comfortable is the CLS-Class? The CLS is extremely comfortable on long drives thanks to minimal noise, outstanding seat comfort and an excellent climate control system. The engine is impeccably smooth too. The front seat's combination of soft leather and firm padding provides great long-distance support and comfort.
At highway speeds, the CLS provides exceptional isolation from wind noise. There's little engine noise aside from a muted growl during hard acceleration. Engine vibration is nearly nonexistent. The only minor demerit is that tire noise over seamed or ridged pavement is more noticeable than we expect for a car like this.
Interior
8.0/10How’s the interior? The CLS' controls are easy to use thanks to intuitive and straightforward interfaces. The screen menus can seem overly complicated at first, but they are well organized. The many ways to interface with the infotainment screen (hard keys, knob, touchpad, steering wheel touch nubs, voice) make it easier to use.
As for interior space, the CLS provides plenty of elbow room and legroom in front. But headroom is compromised a bit compared to the related E-Class. That's especially true in the back seat because of the sloped roofline.
Technology
8.5/10How’s the tech? The CLS' display screen is large and impressive, and the infotainment interface has a lot of capability. Sound quality from optional Burmester premium audio is exceptional. Using the knob is natural and effective, or use the nubs on the steering wheel (they take a brief period to learn).
The driver aids constitute a long list and work quite well. Our test car was equipped with the optional Driver Assistance package that includes every assist feature imaginable. All are extremely well calibrated, and false positives are rare.
Storage
7.5/10How’s the storage? The CLS' trunk has less storage space than the E-Class sedan's as well as the trunks of most other midsize luxury sedans. Still, there's enough room here to swallow a few weekend luggage bags. The 40/20/40-split folding rear seatback helps improve utility, so practicality remains decent for a sedan whose existence is predicated on style. In the cabin there's adequate small-item storage with huge door pockets and a divided center console.
Fuel Economy
8.0/10How’s the fuel economy? The AMG CLS 53 we tested gets an EPA-estimated 23 mpg combined. This is above-average fuel economy for a performance-oriented luxury sedan.
Value
8.0/10Is the CLS-Class a good value? The CLS is impeccably built. It looks and feels special. This is not an inexpensive car, but owners will be satisfied that they got their money's worth every time they get in. That said, it's hard to justify buying a CLS over a regular E-Class sedan considering it costs thousands of dollars more and has less rear headroom.
Wildcard
8.5/10Plenty of power and a delightfully refined driving experience underscore this sedan's appeal. It's quite capable even on fast drives, though it stops short of hooliganism. Stylewise, the CLS stands out.
Which CLS-Class does zzdcar recommend?
Go for the AMG CLS 53 to make the most of the stylish and powerful ethos of the CLS. This top-level version comes with a serious bump in horsepower over the base model, plus sporty upgrades and AMG interior trimmings to add an air of exclusivity. If you're already considering a luxury sedan big on personality, why not go all the way?
