2025 Mercedes-AMG SL-Class Review

2025 Mercedes-AMG SL-Class – Overview

The 2025 Mercedes-AMG SL-Class is a thoroughly modern take on the iconic blend of speed, style, and sophistication that has defined the SL for decades. Exclusively offered under the AMG badge since its 2022 revival, the SL-Class now sports a power-operated soft top and a pair of diminutive rear seats, granting it true two-plus-two functionality. While the rear seats are better suited for luggage or small passengers than adults, the cabin remains unmistakably Mercedes, featuring massaging seats, upscale trim, and a large central touchscreen that tilts when the top is lowered to reduce glare.

Performance is at the forefront, with an adaptive suspension that effortlessly transitions between sporty handling and luxurious comfort. Powertrain options span from the turbocharged four-cylinder in the SL43 to the twin-turbo V8s in the SL55 and SL63. For those chasing maximum performance, the SL63 S E Performance adds an electric motor, delivering a staggering 805 horsepower. In essence, the 2025 Mercedes-AMG SL-Class is a masterful balance of extremes—equally capable of scorching down winding roads at thrilling speeds or cruising with elegance on city streets.

When Is the 2025 Mercedes-AMG SL-Class Coming Out?

Mercedes-Benz plans to launch the 2025 Mercedes-AMG SL-Class in the late third quarter of 2025. Orders are expected to open a few months earlier, giving enthusiasts a chance to customize trims, packages, and options.

What’s New for 2025 Mercedes-AMG SL-Class?

The SL43’s 2.0-liter four-cylinder engine has been given a boost, now producing 416 horsepower—an increase of 43 hp. For those seeking more customization, Mercedes-AMG introduces a new dark blue fabric top and two fresh Manufaktur Signature exterior paint options: China Blue and Silicon Grey. Interior choices have also expanded, with new Manufaktur combinations in Signature Yacht Blue/Black and Mystic Red/Black. Additionally, black-painted brake calipers are now available on the SL55, SL63, and SL63 S E Performance models, adding a sportier visual flair.

Pricing and Which One to Buy

The 2025 Mercedes-AMG SL-Class ranges from $113,100 to $208,300, depending on the chosen trim and optional features.

All SL models come generously equipped with luxury features, including massaging seats, a head-up display, and a premium Burmester audio system. For those chasing peak performance, the SL63 stands out, delivering the full power of its twin-turbo V8. Both the SL55 and SL63 are available in Touring or Performance variants, with the Performance version adding a front-axle lift for easier clearance over speed bumps and darkened exterior trim for a more aggressive appearance.

Engine, Transmission, and Performance

All 2025 Mercedes-AMG SL-Class models except the entry-level SL43 are powered by a twin-turbo 4.0-liter V8 borrowed from the AMG GT, while the SL43 relies on a 416-hp turbocharged 2.0-liter inline-four. In the SL55, the V8 produces a robust 469 horsepower, which jumps to an impressive 577 hp in the SL63. A nine-speed automatic transmission is standard across the lineup. The SL55 and SL63 also feature all-wheel drive and four-wheel steering, whereas the SL43 comes exclusively with rear-wheel drive.

These potent powertrains put the SL in competition with convertible BMW 8 Series and Lexus LC models, as well as sportier rivals like the Porsche 911. During our Lightning Lap testing, the SL63 demonstrated remarkable track capability. On everyday roads, however, the multitude of selectable drive modes can feel a bit overwhelming, hinting that the car hasn’t quite settled on a single driving personality. At the top of the range, the SL63 S E Performance plug-in hybrid combines the twin-turbo V8 with an electric motor for a staggering 805 horsepower, delivering both electrifying performance and hybrid efficiency.

0–60-MPH Times

Acceleration is instantaneous across the 2025 Mercedes-AMG SL-Class lineup. In our testing, the SL63 sprinted to 60 mph in just 3.0 seconds, accompanied by a deep, throaty exhaust note. While we haven’t yet tested the SL55, the entry-level SL43 reached 60 mph in 4.5 seconds on our track. The SL63 S E Performance plug-in hybrid proved exceptionally potent during our initial drive, and we estimate it can hit 60 mph in an astonishing 2.4 seconds.

Fuel Economy and Real-World MPG

The 2025 Mercedes-AMG SL55 and SL63 both carry an EPA rating of 13 mpg city and 21 mpg highway. By comparison, the V-8–powered BMW 8 Series convertible edges out the SL by a few miles per gallon, as does the Lexus LC when equipped with its V-8 engine. The SL43, however, delivers notably better efficiency, with estimated ratings of 19 mpg city and 27 mpg highway. We have yet to test the new 2025 Mercedes-AMG SL-Class on our 75-mph highway fuel-economy track—a key part of our rigorous evaluation process—to determine its real-world performance. For additional details on the SL’s fuel economy, refer to the EPA’s official website.

Interior, Comfort, and Cargo

The 2025 Mercedes-AMG SL-Class places driver and passenger low in the cabin, with window bases roughly at shoulder height. Leather surfaces with contrasting stitching abound, while turbine-style air vents add a distinctive, stylish touch. Instrumentation is fully digital, and a large portrait-oriented center touchscreen handles most functions. Some controls, such as audio volume and the power top, rely heavily on touch inputs—a design choice that can feel fiddly.

Seats are equipped with heating, cooling, and massage functions, and feature Mercedes’ Airscarf system, which directs warm air to occupants’ necks on chilly days. The tiny rear seats, with their upright backs, aren’t intended for passengers but are useful for stashing briefcases or bags, especially given the modest trunk space.

Infotainment and Connectivity

Every 2025 Mercedes-AMG SL-Class comes equipped with Mercedes’ latest MBUX infotainment system, featuring the “Hey Mercedes” voice assistant and a large 11.9-inch touchscreen that can tilt for optimal viewing. A 12.3-inch digital gauge cluster is standard, providing clear, customizable information. Both Apple CarPlay and Android Auto are included, and the navigation system offers optional augmented reality guidance. Audio enthusiasts will appreciate the standard Burmester sound system, while the SL63 can be upgraded with a premium surround-sound version for an even richer listening experience.

Safety and Driver-Assistance Features

The 2025 Mercedes-AMG SL-Class comes standard with several key driver-assistance technologies, including automated emergency braking with pedestrian detection and blind-spot monitoring. Other features, such as adaptive cruise control with lane-centering and lane-keeping assist, are available as optional upgrades. For detailed crash-test results, refer to the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) websites.

Key Safety Features:

• Standard automated emergency braking with pedestrian detection

• Available lane-departure warning with lane-keeping assist

• Available adaptive cruise control with lane-centering functionality

Warranty and Maintenance Coverage

Mercedes-AMG’s standard warranty for the SL-Class is straightforward, covering four years or 50,000 miles with no added perks. Unlike competitors such as the BMW 8 Series or Lexus LC, which include complimentary scheduled maintenance, the SL does not offer any free service programs, making those rivals potentially more appealing for lease customers.

Key Warranty Details:

• Limited warranty: 4 years / 50,000 miles

• Powertrain warranty: 4 years / 50,000 miles

• Complimentary scheduled maintenance: Not included
