2028 Mercedes-Benz SL 55 Roadster : Price, Range, Specs, and Features

2028 Mercedes-Benz SL 55 Roadster continues the legendary SL formula with a modern AMG twist, combining handcrafted V8 power, open-top luxury, advanced technology, and everyday usability in one of the most desirable grand touring convertibles on the market. While Mercedes-Benz has not officially revealed every final specification for the 2028 model yet, the upcoming SL 55 Roadster is expected to build on the current AMG SL platform with subtle styling refinements, upgraded infotainment software, improved driver-assistance systems, and enhanced performance tuning.

Designed for drivers who want a luxurious roadster that can also deliver thrilling acceleration and sharp handling, the 2028 SL 55 sits perfectly between comfort-oriented cruising and full AMG aggression. It offers the emotional appeal of a classic V8-powered convertible while still embracing modern digital technology and premium craftsmanship.

Estimated Price of the 2028 Mercedes-Benz SL 55 Roadster

The estimated starting price of the 2028 Mercedes-Benz SL 55 Roadster is expected to begin around $150,000 USD, depending on options, customization packages, and regional taxes. Fully loaded examples with AMG Performance packages, carbon fiber trim, premium leather interiors, and advanced driver assistance systems could easily exceed $170,000.

The pricing places the SL 55 directly against rivals such as the Porsche 911 Cabriolet, BMW M8 Convertible, and Aston Martin Vantage Roadster.

Performance and Engine

Under the hood, the 2028 SL 55 Roadster is expected to continue using Mercedes-AMG’s handcrafted 4.0-liter twin-turbocharged V8 engine paired with AMG Performance 4MATIC+ all-wheel drive and a 9-speed automatic transmission. Current AMG SL 55 models produce around 469 horsepower and 516 lb-ft of torque, and the 2028 version could receive minor performance improvements for even sharper acceleration and responsiveness. 0

Acceleration from 0 to 60 mph is expected to remain around 3.7 to 3.8 seconds, delivering explosive launches with the unmistakable AMG V8 soundtrack that enthusiasts still love. The adaptive suspension system helps the SL 55 remain comfortable during highway cruising while transforming into a surprisingly agile sports car in Sport+ mode.

The steering feels precise, the all-wheel-drive system provides excellent traction, and the AMG-tuned exhaust creates a deep aggressive note that makes every drive memorable.

Battery, Driving Range, and Charging Time

Unlike the plug-in hybrid AMG SL 63 S E Performance, the 2028 SL 55 Roadster is expected to remain a traditional gasoline-powered performance convertible rather than a fully electric vehicle. Because of this, there is no large EV battery pack or charging requirement.

However, Mercedes-Benz may integrate a mild-hybrid system for improved efficiency and smoother engine start-stop functionality. Fuel economy is expected to remain similar to current SL 55 models, offering approximately 14 mpg city and 21 mpg highway. 1

The estimated driving range should comfortably exceed 350 miles on a full tank, making the SL 55 a capable long-distance grand tourer.

Exterior Styling

The 2028 SL 55 Roadster features one of the most elegant yet muscular designs in the luxury convertible segment. Mercedes-AMG has successfully blended classic SL proportions with modern aerodynamic details and aggressive AMG styling cues.

The long hood, wide stance, Panamericana grille, slim LED headlights, sculpted bodywork, and retractable soft top give the roadster a dramatic presence whether parked or moving. Large AMG wheels, quad exhaust outlets, and performance-focused air intakes reinforce its sporty personality.

Unlike older generations that used folding hardtops, the modern soft-top design reduces weight and improves cargo practicality. Some enthusiasts still prefer the old retractable hardtop setup, but many owners appreciate the cleaner proportions and lighter feel of the current SL platform. Discussions among AMG enthusiasts also praise the SL 55 for balancing comfort, style, and everyday usability. 2

Cabin Interior and Comfort

Inside, the 2028 Mercedes-Benz SL 55 Roadster delivers a cabin that feels both futuristic and handcrafted. Premium leather upholstery, metal speaker grilles, ambient lighting, contrast stitching, and AMG-specific trim create an upscale atmosphere worthy of the Mercedes-Benz flagship roadster.

The seats are supportive enough for spirited driving while remaining exceptionally comfortable for long highway journeys. Heated and ventilated seating, neck-level AIRSCARF heating, and advanced climate management allow drivers to enjoy open-top motoring even in cooler weather.

Unlike many strict two-seat sports cars, the SL 55 offers a small rear seating area, making it slightly more practical for short trips or additional storage.

Infotainment and Technology

The infotainment system is expected to feature the latest generation of Mercedes-Benz MBUX software with a large vertically oriented touchscreen, wireless Apple CarPlay, Android Auto, voice controls, navigation, and AMG performance displays.

One of the SL’s clever features is the adjustable center touchscreen that can tilt to reduce sunlight glare while driving with the roof down. The digital instrument cluster remains crisp and highly customizable, while optional Burmester premium audio transforms the cabin into a concert hall.

Mercedes-Benz also continues improving connectivity features, over-the-air software updates, and AI-powered voice assistance for a more modern ownership experience.

Safety Technologies

The 2028 SL 55 Roadster is expected to include a wide range of advanced safety and driver assistance technologies. Features should include adaptive cruise control, blind-spot monitoring, lane-keeping assist, automatic emergency braking, parking assist, surround-view cameras, and traffic sign recognition.

The rigid chassis structure and advanced stability systems help maintain confidence even during aggressive driving, while modern driver aids make the SL easier to handle in daily traffic situations.

Practicality

Although the SL 55 Roadster focuses heavily on performance and luxury, it remains more practical than many exotic convertibles. The trunk space is usable enough for weekend luggage, and the comfortable ride quality makes long-distance touring enjoyable.

The soft top operates quickly and quietly, allowing drivers to transition from coupe-like comfort to open-air freedom in seconds. Visibility is good for a performance convertible, and the cabin provides enough storage for everyday essentials.

Still, rear-seat space remains limited, and maintenance costs are expected to be high due to the AMG performance engineering and premium luxury components.
