Mercedes-AMG SL Roadster: Price, Specs, Review
The Mercedes-AMG SL Roadster is a luxury performance convertible that combines a power fabric roof, a four-seat 2+2 cabin, and a choice of high-output AMG engines. The current U.S. range includes the four-cylinder AMG SL 43, V8-powered AMG SL 55, and more powerful AMG SL 63.
The SL is made for buyers who want open-air driving without giving up modern technology, all-weather capability, or long-distance comfort. It is not a low-cost sports car, and the rear seats and trunk are limited, but it is more usable than a two-seat roadster.
For most buyers, the AMG SL 55 is the right choice. It offers the handcrafted V8, all-wheel drive, and a 3.8-second claimed 0–60 mph time while costing far less than the SL 63.
WheelPedia Rating: 7.9/10
The Mercedes-AMG SL Roadster earns a 7.9/10 WheelPedia Rating for its engaging performance, refined convertible experience, high-quality interior, and broad engine range.
Its main drawbacks are a six-figure starting price, small cargo space, tight rear seats, high V8 fuel use, and costly insurance, tires, brakes, and out-of-warranty repairs.

Expert Tip:
The AMG SL 55 is the recommended trim for most buyers. It has the V8 sound and power many shoppers expect from an AMG roadster, plus all-wheel drive and rear-axle steering, without the $42,750 step up to the SL 63.
About the Mercedes-AMG SL Roadster
The SL is Mercedes-AMG’s luxury grand-touring roadster. It is more comfortable and more technology-rich than a dedicated track car, but much more performance-focused than a traditional luxury convertible.
Unlike the Mercedes-Benz CLE Cabriolet, the SL is an AMG-only model. It uses a lightweight fabric roof instead of a retractable hardtop and has a compact 2+2 cabin. This provides occasional rear seating but not meaningful adult rear-seat space.
The lineup is easy to understand. The SL 43 is the lighter and more fuel-efficient entry model. The SL 55 brings the V8 experience and all-wheel drive. The SL 63 adds more power, active ride-control suspension, and higher-performance hardware for buyers who place driving ability above price and comfort.
Price and Trims
These are current U.S. starting MSRPs. Paint, wheels, carbon-fiber parts, luxury packages, destination, and dealer pricing can add substantially to the final amount.
| Trim | Starting MSRP | Powertrain | Drivetrain | Claimed 0–60 mph |
| AMG SL 43 Roadster | $114,900 | 416-hp 2.0L turbo mild hybrid | RWD | 4.6 sec |
| AMG SL 55 Roadster | $147,750 | 469-hp 4.0L twin-turbo V8 | AWD | 3.8 sec |
| AMG SL 63 Roadster | $190,500 | 577-hp 4.0L twin-turbo V8 | AWD | 3.5 sec |
The SL 43 costs meaningfully less, has four seats, and is the most efficient version. It is very quick, but its engine note and rear-wheel-drive layout give it a different character from the V8 models.
The SL 55 is the right fit for most V8 buyers. The SL 63 is faster and has more specialized chassis equipment, but the large price difference is difficult to justify unless its extra performance will be used regularly.
Engine, Powertrain, and Performance
| Model | Engine / Hybrid System | Power | Torque | Drivetrain |
| AMG SL 43 | Hand-built 2.0L turbo four-cylinder with mild-hybrid assist | 416 hp | 369 lb-ft | RWD |
| AMG SL 55 | Hand-built 4.0L twin-turbo V8 | 469 hp | 516 lb-ft | AWD |
| AMG SL 63 | Hand-built 4.0L twin-turbo V8 | 577 hp | 590 lb-ft | AWD |
The SL 43 uses an electrically assisted turbocharger and a belt-driven starter-generator. It provides quick response and gives the SL a more balanced feel than the heavier V8 models. It is also the only rear-wheel-drive version.
The SL 55’s V8 makes its torque from low engine speeds, which suits relaxed highway driving as well as quick acceleration. AMG Performance 4MATIC+ all-wheel drive varies power distribution between the axles as conditions and driving inputs change.
The SL 63 adds 108 hp over the SL 55, along with AMG ACTIVE RIDE CONTROL suspension. It is the most focused current SL, but it remains a roadster rather than a stripped-out circuit car.
0–60 MPH Performance
| Model | Manufacturer-Claimed 0–60 mph Time |
| AMG SL 43 Roadster | 4.6 sec |
| AMG SL 55 Roadster | 3.8 sec |
| AMG SL 63 Roadster | 3.5 sec |
These manufacturer figures come from controlled test conditions. Road surface, weather, tires, passenger load, elevation, and launch technique can affect real-world results. The SL 43 is already quick enough for nearly any public-road situation, while the V8 models provide much stronger passing performance and a more dramatic character.
Driving Experience
The AMG SL blends grand-touring comfort with performance-car responses. Its seating position is lower and more focused than in a standard luxury convertible, but the cabin has enough adjustment and refinement for long trips.
The SL 43 is the easiest version to live with. It is lighter than the V8 models, has rear-wheel drive, and uses 19-inch wheels. It feels more agile than its power figure suggests, though the four-cylinder does not deliver the sound or low-speed torque of the V8.
The SL 55 is the sweet spot. Its V8, all-wheel drive, adaptive damping, and 2.5-degree rear-axle steering give it strong traction and composure without the more intense setup of the SL 63. It is the better choice for buyers who want to drive the car often in different weather conditions.
The SL 63 is firmer and more urgent. Its active suspension helps reduce body movement in corners, but rough pavement, large wheels, and summer tires are still noticeable. A front-axle lift system is particularly worthwhile if your regular routes include steep driveways or parking-garage ramps.
Fuel Economy
| Model | City | Highway | Notes |
| AMG SL 43 Roadster | 19 mpg | 27 mpg | Most efficient current SL |
| AMG SL 55 Roadster | 14 mpg | 21 mpg | V8, AWD |
| AMG SL 63 Roadster | 14 mpg | 21 mpg | V8, AWD |
All AMG SL models require premium unleaded gasoline and use an 18.5-gallon fuel tank. The SL 43 is the better choice for buyers who will cover high annual mileage. V8 fuel costs will be significant, especially in city traffic or enthusiastic driving.
Interior, Comfort, and Technology
The SL cabin feels special without becoming overly complicated. Its driver-focused dash uses a portrait-format MBUX touchscreen, digital instruments, and AMG-specific displays for performance information.
Standard and available equipment includes:
- Digital instrument display and central MBUX touchscreen
- Voice control and connected-services capability
- Wireless Apple CarPlay and Android Auto compatibility
- AMG Performance steering wheel and drive-mode controls
- Power front seats with memory
- Heated and ventilated front seats
- AIRSCARF neck-level heating
- Nappa leather and available MANUFAKTUR upholstery
- Burmester surround-sound system
- Head-up display
- Surround-view camera system
- Available front-axle lift system
The 2+2 layout is useful, but rear-seat accommodation is limited. The rear seats work better for children, small bags, or occasional short journeys than regular adult travel. Front-seat occupants have enough room for long drives, and the available neck heating makes cool-weather top-down use more comfortable.
Dimensions, Cargo, and Practicality
| Dimension | Measurement |
| Length | 185.2 in. |
| Width without mirrors | 75.4 in. |
| Width with mirrors | 82.7 in. |
| Height, roof up | 53.5 in. |
| Wheelbase | 106.3 in. |
| Front headroom | 37.7 in. |
| Front legroom | 41.5 in. |
| Front shoulder room | 56.3 in. |
| Rear headroom | 32.7 in. |
| Rear shoulder room | 44.1 in. |
| Cargo capacity | 7.5 cu. ft. |
| Seating capacity | 4 |
The power Z-fold fabric top opens or closes in around 15 seconds at speeds up to 37 mph. It is quieter and more weather-resistant than older soft tops, but it still takes trunk space. The 7.5-cubic-foot cargo area is enough for soft luggage and day-trip items, not several large suitcases.
If you need regular rear-seat use or a larger trunk, the Mercedes-Benz CLE Cabriolet is a more practical luxury convertible. The SL is for buyers who put the driving experience first.
Exterior Design
The AMG SL has a long hood, short rear deck, wide stance, and a fabric roof that gives it a classic roadster profile. The SL 43 is relatively understated, while the SL 55 and SL 63 add V8-specific bodywork, larger wheels, and a more aggressive exhaust treatment.
With the roof down, the SL has the open-air look buyers expect. With it raised, the three-layer fabric top retains a clean silhouette without the weight and mechanical complexity of a retractable hardtop.
Safety Features and Ratings
The SL includes driver-assistance and parking technology, but those systems cannot overcome the limits of tires, road surface, visibility, or driver judgment.
Standard and available features include:
- Active Brake Assist
- Active Distance Assist DISTRONIC adaptive cruise control
- Active Steering Assist
- Active Lane Keeping Assist
- Active Blind Spot Assist with exit warning
- Active Emergency Stop Assist
- Traffic Sign Assist and active speed-limit assistance
- ATTENTION ASSIST driver monitoring
- Crosswind Assist
- Surround-view camera system
- PARKTRONIC with Active Parking Assist
- DIGITAL LIGHT LED headlamps and Adaptive Highbeam Assist
- Mercedes-Benz Emergency Call service
IIHS has not published a crash-test rating for the current AMG SL Roadster. Buyers should check IIHS vehicle ratings and NHTSA’s current listings before purchase in case a rating becomes available.
Reliability, Warranty, and Ownership
The AMG SL contains complex powertrains, adaptive suspension systems, a power fabric roof, large performance tires, and expensive brakes. Purchase decisions should account for the full ownership cost, not only the starting MSRP or monthly payment.
The SL 43 will generally have lower fuel costs, but it is still a sophisticated performance car. The V8 models carry higher costs for fuel, insurance, tires, brake work, and repairs. Regular top mechanism checks and proper roof care also matter on a convertible.
| Coverage | Length |
| New Vehicle Limited Warranty | 4 years / 50,000 miles |
| Roadside Assistance | 4 years / 50,000 miles |
| Federal Emissions Warranty | Up to 8 years / 80,000 miles on selected components |
| Scheduled maintenance interval | Once per year or 10,000 miles |
Mercedes-Benz offers prepaid maintenance and extended-warranty coverage. Used-car buyers should inspect the roof operation and seals, tire condition, wheel damage, brake wear, electronic functions, service history, and signs of track use. A pre-purchase inspection by a Mercedes-Benz or AMG specialist is a sensible step.

Before financing a six-figure convertible, review car loan preapproval and the difference between APR and interest rate on a car loan.
Used-car buyers should read how to check a car’s accident history and how to read a VIN number before making an offer.
For a larger Mercedes luxury car, compare the SL with the Mercedes-Benz S-Class. Buyers considering a fixed-roof performance coupe should also look at the Mercedes-AMG GT.
Should You Buy the Mercedes-AMG SL Roadster?
Buy the AMG SL if you want an open-top Mercedes with serious performance, a premium cabin, usable front-seat comfort, and occasional rear seating. It makes sense for buyers who will enjoy weekend drives, road trips, and top-down travel in favorable weather.
Choose the AMG SL 43 if you want the lowest purchase price, lower fuel use, and a lighter rear-wheel-drive car. Choose the AMG SL 55 if you want the V8 experience and the strongest balance of price, speed, all-weather traction, and daily usability. Choose the AMG SL 63 only if the additional performance and active chassis hardware matter more than the large price increase.
Skip the SL if you need a roomy rear seat, large luggage capacity, low running costs, or a vehicle that will be regularly used in harsh weather. A coupe, sedan, or SUV will be more practical.
