The 2027 Mercedes-AMG SL 55 Roadster brings the engine many buyers expect when they see the letters AMG: a handcrafted 4.0-liter biturbo V8. Producing 469 horsepower and 516 lb-ft of torque, it sends the SL from 0–60 mph in an estimated 3.8 seconds and on to an electronically limited 183-mph top track speed. Standard AMG Performance 4MATIC+ all-wheel drive, adaptive AMG RIDE CONTROL suspension and rear-axle steering give the SL 55 far more sophisticated performance hardware than its open-air grand-touring shape might initially suggest.

The V8 delivers its maximum torque beginning at just 2,250 rpm and holds it through 4,500 rpm, giving the SL 55 the broad midrange surge that makes a large-displacement AMG feel effortless. Twin turbochargers sit within the engine’s hot V for quicker response, while SL-specific changes include repositioned intercoolers, active crankcase ventilation and increased boost pressure. Each engine is assembled by a single AMG craftsperson and carries that builder’s signature.

AMG Performance 4MATIC+ continuously changes the front-to-rear torque split according to driver input, road conditions and available grip. The system can send 100 percent of available power to the rear wheels, allowing the SL to retain a rear-driven feel when conditions permit. An AMG SPEEDSHIFT MCT nine-speed transmission handles the V8’s output without relying on a conventional torque converter.

The SL 55 also receives AMG RIDE CONTROL suspension with three-stage adaptive damping. Comfort, Sport and Sport+ settings progressively tighten the dampers according to wheel movement, lateral acceleration and vehicle speed. Standard 2.5-degree rear-axle steering helps make the 185.2-inch-long roadster easier to maneuver at lower speeds while contributing to stability and response as speeds rise.

The three-layer Z-fold acoustic soft top weighs substantially less than the retractable hardtop used by the previous SL. It can operate in approximately 15 seconds at speeds up to 37 mph, letting the driver lower or raise the roof without finding a place to stop. Seating for four makes this generation of SL substantially more versatile than a traditional two-seat roadster, while 7.5 cubic feet of cargo space remains available behind the cabin.

Inside, third-generation MBUX supplies the digital interface, while Active Distance Assist DISTRONIC handles adaptive cruise-control duties. Standard 20-inch AMG wheels carry staggered summer performance tires, and available personalization ranges from MANUFAKTUR paint and Nappa leather to carbon-fiber trim and 21-inch forged wheels. Starting at $147,750, the 2027 AMG SL 55 is the first V8 in the lineup and arguably the model that most closely captures the classic SL formula: fast enough to be thrilling, comfortable enough to cross states, and at its best with the roof down.

AMG RIDE CONTROL

Electronically controlled three-stage adaptive damping adjusts suspension behavior according to vehicle speed, road conditions and selected drive mode.

Rear-Axle Steering

The rear wheels can steer up to 2.5 degrees, improving maneuverability at low speeds and contributing to stability and agility at higher speeds.

Active Distance Assist DISTRONIC

Radar-based adaptive cruise control automatically varies speed according to surrounding traffic and can brake the SL to a stop when required.

20-Inch AMG Wheels

Standard staggered 20-inch AMG twin five-spoke wheels carry 265/40R20 front and 295/35R20 rear summer performance tires.
