The 2026 Mercedes-AMG SL is an impressive luxury roadster with a glorious heritage.

Cons

Power, Ride and Handling

Driving Impressions

Drivetrains in the 2026 AMG SL go from great to good gracious. The SL 43 flexes its 416 horsepower to sprint from standstill to 60 mph in a perfectly zippy 4.8 seconds. Most SL buyers don’t need to go faster than this. But the ones who do can put the SL 55’s 469 horsepower to the ground and hit 60 mph a second sooner. Or shave off another 0.3 of a second in the 577-horsepower SL 63.
To compare with the SL 43, the “base” Porsche 911 Carrera Cabriolet has 379 horsepower and is about half a second quicker to 60 mph, while the Mercedes beats the BMW 840i Convertible by a small margin. Anyway, it isn’t all about the numbers with an SL.
Although there is another twist with the AMG SL 63 S E Performance, which harnesses electric power as well as combustion to push the SL to extremes it’s never known before. It develops a truly awesome 805 horsepower and up to 1,047 lb-ft of torque. The 60-mph mark is but a fleeting event that happens just 2.8 seconds (gasp) into its rush to a top speed of 198 mph.
In general, we’ve found the SL does a fantastic job of balancing engaging performance with a luxurious ride quality. We could cruise for hours on the highway with no complaints. Yet the SL is equally in its element on twisting back roads, thanks to the all-wheel steering system (in the V8-powered models) and the well-tuned AMG Ride Control suspension system.
<h3>Fuel Economy</h3>
It’s unlikely that SL buyers will care too much about gas bills. That said, the SL 43 achieves 22 mpg in combined city/highway driving. Which is fine, we suppose. The BMW 840i Convertible gets 24 mpg combined, about as good as this class gets. The SL 55 and SL 63 both run to 16 mpg combined. The SL 63 S E Performance achieves the equivalent of 29 mpg combined (MPGe) or 18 mpg combined once the battery is depleted. Its battery-only range is negligible.

Athletic Exterior

Exterior

We’d say the Mercedes-AMG SL is handsome. It looks simultaneously expensive and athletic, with sports-car proportions and stylish wheel options. This current SL forgoes the retractable hardtop of previous SL generations in favor of a powered soft top. We think it looks great with the roof down.
This year, the Manufaktur program adds Ireland Mid-Green Magno (not mango), Cote d’Azur light blue, and Orange Flame Metallic. And then there’s the impressive list of Manufaktur Exclusive finishes.

FAQs

Our Favorite Features and Tech

Favorite Features

11.9-inch touchscreen 
The SL’s infotainment system has excellent graphics and user-friendly features, including standard navigation and voice control. We love that the angle of the screen is adjustable to reduce glare.
Airscarf 
Warm-air vents in the front seats make the SL more comfortable to drive with the top down in cooler weather. Factor in all-wheel drive and the SL could be a car for all seasons.
AMG Performance 4Matic+ 
This high-performance all-wheel drive system comes standard in V8-powered SL models. It optimizes torque to all four wheels for a sublime driving experience.
AMG Active Ride Control 
This sophisticated adaptive suspension system can adjust each corner for ultimate stability, even in tight corners at high speeds. We’ve experienced it and found it does everything Mercedes-Benz claims. It’s standard in the SL 63 and optional in the lower trims.
AMG Dynamic Select 
The standard AMG Dynamic Select system includes Comfort, Slippery, Sport and Sport+ modes, plus an Individual setting that drivers can fine-tune to their liking. We’ve found that each one has its own distinct feel.
Driver Assistance Package 
This optional package adds an array of safety tech such as adaptive cruise control, evasive steering assistance, active lane keeping, active emergency stop assistance, and route-based speed adaptation. We think it’s worth choosing.

Classy Interior

Interior

We could sit in these front seats all day, they’re so well-shaped and comfortable. Mercedes-Benz invariably impresses us with its superb cabin materials and build quality, and that’s exactly what’s going on here. Everything we touch feels classy. We also appreciate the technology, like the highly customizable digital gauge cluster and the user-friendly infotainment system with gorgeous graphics.
The back seats are an afterthought &#8212; we could hardly fit back there without sliding the front seats all the way forward. Maximum trunk space is 8.5 cubic feet &#8212; more than the Lexus LC 500 Convertible, less than the BMW 8 Series Convertible.
We cover the ultra-luxurious new-for-2026 <a href="https://www.kbb.com/mercedes-benz/mercedes-maybach-sl/">Mercedes-Maybach SL</a> in a separate review.

KBB Editors' Overview

Ah, the SL. One of the most recognizable <a href="https://www.kbb.com/mercedes-benz/">Mercedes-Benz</a> cars of all time. As the full name suggests, this is the AMG-fettled lineup. If those letters don’t already ring a glorious bell, then you’ve now been notified that AMG variants are the fastest, most driver-focused versions of vehicles wearing that evocative 3-pointed star badge.
Although the SL name has been around since 1954, this current generation is still fresh &#8212; having launched for the 2022 model year. The tech remains impressive while the car also exhibits timeless qualities of classiness and a fantastic driving experience.
We’ve logged hundreds of hours driving and evaluating this generation of <a href="https://www.kbb.com/cars/highest-horsepower-luxury-cars/">high-horsepower luxury cars</a>, including the Mercedes-AMG SL.
