How Does the 2026 Mercedes-Benz AMG® SL 43 Roadster Perform?

The 2026 Mercedes-Benz AMG® SL 43 Roadster isn’t shy about showing off what it can do. This lightweight, open-air machine brings race-inspired engineering to everyday streets, and it does it with a playful attitude that makes every drive feel like you just stole the spotlight. Under the hood sits a handcrafted AMG 2-liter inline-4 turbo with hybrid assist, built under the “one man, one engine” philosophy. It pushes out 416 hp and 369 lb.-ft. of torque, using technology borrowed straight from Formula 1®. Thanks to its electric exhaust-gas turbocharger, the engine spools up instantly—even when you roll gently back onto the throttle after coasting—so power rushes in right when you want it. Paired with that engine is the AMG SPEEDSHIFT® MCT 9-speed transmission. It uses a wet startup clutch instead of a torque converter, which lets it fire off quick, crisp gear changes. Need to pass someone fast? The transmission can jump multiple gears down in one shot. Want a calmer ride home? Comfort mode can temporarily decouple the driveline and help you coast to save fuel. 

AMG DYNAMIC SELECT brings personality into the mix. You can scroll between modes like Comfort, Sport, Sport+, Slippery, and a customizable Individual setting. Each one changes how the throttle reacts, how loudly the exhaust growls, how stiff the suspension feels, and how the transmission shifts. If you want more control on the fly, the AMG DRIVE UNIT on the steering wheel lets you change settings instantly—perfect for switching from relaxed cruising to spirited canyon carving. Handling gets extra help from AMG DYNAMICS, which adjusts yaw behavior and steering response. In Sport+, the car feels tight and incredibly alert through turns. The two-stage direct injection, NANOSLIDE-coated cylinders, and Hybrid Starter-Generator in the SL 43 work together to deliver power efficiently, respond quickly, and keep temperatures in check during hard driving. The 4-wheel multilink suspension hugs the road, while the AMG Performance Exhaust System adds a throaty soundtrack that pops with every shift. And when it’s time to rein things in, the high-performance composite brakes—with silver AMG calipers—step in with serious stopping force. 

From the steering feel to the turbo rush, the 2026 AMG® SL 43 performs like a roadster that’s eager to play every chance it gets.
