Mercedes AMG SL55 Performance and Driving Experience
Despite carrying the “55” badge, the SL55 feels remarkably close to the SL63 in real-world performance. Acceleration from 0–60 mph is achieved in the mid-to-high 3-second range, only slightly behind the SL63’s low-3s benchmark. Four-wheel steering, AMG’s performance package, and an advanced 48-volt active anti-roll system ensure confident handling with minimal body roll, even on challenging tracks such as Toronto Motorsports Park.
The SL55’s all-wheel-drive system and performance differential deliver excellent traction, making it suitable for year-round driving, while the exhaust note delivers AMG’s signature crackles and backfires. An AMG Speedshift MCT 9-speed automatic transmission complements the car’s responsive and dynamic character.
Design and Styling
Visually, the Mercedes AMG SL55 is nearly identical to the SL63, with differences limited to badging. The test model showcased a striking Hyper Blue Metallic exterior paired with a cashmere leather interior, polished wheels, and a fabric roof finished in a contrasting shade rather than black. The overall design emphasizes elegance with a sporty edge, distinguishing it from the AMG GT line.
The cabin reflects Mercedes’ luxury DNA, offering heated neck-level air vents (Airscarf), ambient lighting, and optional massage seats. The infotainment screen tilts to reduce glare, supporting both Apple CarPlay and Android Auto (wired and wireless).

- Performance Package: Active anti-roll system, performance differential, yellow brake calipers, and nose-lift function.
- Driver Assistance Systems: Adaptive cruise control, lane-keeping assist, automatic lane changes, and advanced safety tech.
- Driving Modes: Comfort, Sport, Sport+, and Race modes for a tailored driving experience.
- Convertible Convenience: One-touch roof operation and insulated soft top providing coupe-like refinement when closed.
Pricing and Value
The 2025 Mercedes AMG SL55 starts at $170,000 CAD, with the tested model priced at $188,955 CAD. Compared to the SL63, which costs significantly more, the SL55 delivers nearly identical performance at a lower price point, making it an appealing choice for buyers seeking AMG thrills without stretching into the highest price bracket.
Verdict
The Mercedes AMG SL55 proves to be more than just a “toned-down” version of the SL63. It offers a blend of luxury, performance, and everyday usability, positioning itself as one of the most compelling roadsters in Mercedes’ lineup. For enthusiasts who value driving excitement without excessive badge prestige, the SL55 stands out as a near-perfect balance of performance and value.
