2026 Mercedes-Benz CLE450 Cabriolet: Beautiful, Powerful, and Frustratingly Unfocused
There is a version of the 2026 Mercedes-Benz CLE450 Cabriolet that could be one of the best open-top grand tourers on the market. It has the looks, the badge, the engine, and the pedigree to deliver a truly exceptional experience under the open sky. The problem is that Mercedes-Benz seems to want the CLE450 Cabriolet to be everything at once — a sporty performance machine and a silky-smooth luxury cruiser — and in trying to please everyone, it risks fully satisfying no one. If the brand would simply commit to what this car does best, it would be a much more compelling buy.
What Is the 2026 Mercedes-Benz CLE450 Cabriolet?
The CLE-Class is Mercedes-Benz's answer to consolidating its mid-size coupe and cabriolet lineup. It effectively replaces both the C-Class Coupe and the E-Class Coupe, slotting in as a single, more refined offering that bridges the two segments. The CLE450 Cabriolet is the drop-top variant of this new nameplate, powered by a turbocharged inline-six engine producing around 375 horsepower and mated to a nine-speed automatic transmission sending power to all four wheels via Mercedes' 4MATIC all-wheel-drive system.
On paper, those numbers impress. The inline-six is smooth, cultured, and more than potent enough to make highway merges feel effortless and open-road blasts genuinely exciting. Wrapped in flowing sheet metal that looks every bit the part of a luxury German convertible, the CLE450 Cabriolet is unquestionably a head-turner. And yet, something about the overall package leaves you wanting more clarity of purpose.
The Performance Case: Leave the Corners to AMG
Here is where the CLE450 starts to show its contradictions. Mercedes-Benz has engineered a degree of sportiness into this car that, frankly, it does not quite earn. The steering is weighted to feel more engaged than you might expect from a luxury cabriolet, the suspension tuning leans firmer than truly necessary, and the driving modes nudge you toward the idea that this is a car meant to be hustled through corners.
It isn't. Not really. And that's fine — but Mercedes needs to accept it. The AMG variants exist precisely for buyers who want a Mercedes-Benz that genuinely attacks corners with conviction and purpose. The CLE63 AMG, whenever it arrives, will be built from the ground up to be a performance machine. The CLE450, by contrast, is a different kind of car. It is longer, heavier as a cabriolet, and the fabric roof adds weight and alters the chassis dynamics in ways that no amount of sport-tuning can fully compensate for.
When you push the CLE450 Cabriolet into a corner with enthusiasm, you feel the mass. The body moves, the chassis communicates its limits, and the experience reminds you that you are in a 4,500-pound luxury convertible, not a sports car. That is not a failure — it is simply the nature of the vehicle. The failure is in pretending otherwise.
The Comfort Case: This Is Where the CLE450 Shines
Drop the roof on the CLE450 Cabriolet on a warm evening, dial the suspension to its most relaxed setting, and point it toward a long, winding coastal highway, and something magical happens. The inline-six burbles with a refined hum, the wind management is impressively well-sorted for a cabriolet, and the interior — dressed in quality leather, ambient lighting, and the latest MBUX infotainment system — wraps you in genuine premium comfort.
This is where the CLE450 Cabriolet is not just good but exceptional. As a grand touring convertible, it offers a combination of effortless power delivery, long-distance refinement, and open-air luxury that very few cars at any price point can match. The back seat, while tight, can accommodate adults for shorter journeys. The trunk is reasonably practical for weekend luggage. The fabric roof deploys quickly and seals impressively well against wind and road noise when raised.
In short, when the CLE450 Cabriolet leans into its identity as a comfort-first, long-distance luxury convertible, it is very, very good.

Who Should Buy the 2026 Mercedes-Benz CLE450 Cabriolet?
If you are shopping for a convertible and your priority is wind-in-the-hair grand touring — relaxed, refined, and luxurious — the CLE450 Cabriolet deserves serious consideration. It competes directly with the BMW 4 Series Convertible and the Audi A5 Cabriolet, and in terms of interior quality and powertrain refinement, it arguably leads that class.
If, however, you want a true performance convertible with AMG-level dynamics, save your budget and wait for the AMG variant. The CLE450 will leave you wanting more at the limit, and no amount of sport mode engagement will change the fundamental character of the car.
The Verdict: A Great Car That Needs to Commit
The 2026 Mercedes-Benz CLE450 Cabriolet is not a bad car — far from it. It is genuinely luxurious, beautifully styled, and powered by one of the smoothest six-cylinder engines available in a production automobile today. Its problem is one of identity. By trying to chase sportiness it cannot fully deliver, it muddies the experience of a car that would be significantly more satisfying if it simply leaned harder into comfort, refinement, and grand touring excellence.
Pick a lane, Mercedes. The CLE450 Cabriolet is at its best when it stops pretending to be something it is not. Embrace the comfort, embrace the cruising, and let the AMG badge handle the rest. Do that, and you will have one of the most enjoyable open-top driving experiences available at this price point. Continue straddling both worlds, and you risk building a car that is merely good when it could easily be great.
