2020 Mercedes-Benz SLC Class Review

2020 Mercedes-Benz SLC Class Review
  • SLC 43 is a true sports car
  • Foldable hard-top refinement
  • More affordable SL-Class
  • Available features like Airscarf
  • Not being replaced after 2020
  • Tight for tall or wide drivers
  • SLC 300 is not as fun as it should be
  • The SLC-Class is not being replaced after 2020, so look for a good deal on any remaining models on dealer lots as they attempt to get rid of inventory.
The 2020 Mercedes-Benz SLC-Class sings a pretty swan song—and you can hear it even when the top’s down.

The 2020 Mercedes-Benz SLC-Class will be the last small sports car to wear the badge, at least for the near future. Mercedes says it will discontinue the SLC-CLass after this year, with no replacement in sight. 

Though much older than contemporaries such as the Porsche 718 and BMW Z4, the SLC isn’t without its charms, including its clever folding top and its ample power. We give it 5.6 out of 10.

For 2020, both the SLC300 and hotter SLC43 AMG add a Final Edition, which includes gray paint on the SLC300 and bright yellow on the SLC43. Both also get special styling details and badging to commemorate 24 years on the market.

The SLC has been tweaked several times over the years and redesigned twice, resulting in a cabriolet with current Mercedes styling cues on what is clearly an older body. It still works: It sports forward-leaning proportions and just the right amount of attention to detail inside and out, though the interior has aged in the new era of touchscreens.

In SLC300 form, a turbo-4 generates 241 horsepower for a 0-60 mph time of 5.7 seconds via rear-wheel drive and a 9-speed automatic transmission. We’d have the hotter SLC43 from AMG, however, with its twin-turbo V-6 and 385 hp and improved driving dynamics. The SLC isn’t as engaging to drive as its direct competitors, though we’ve got no complaints from a ride comfort standpoint.

Fit for just two passengers, the 2020 SLC is snug in terms of leg and shoulder room, and trunk space is lacking, even for a small sports car. The quick action of the top does help make up for some of these shortcomings, as does the joy of open-roof motoring.

No crash test data exists for the SLC, and fuel economy ranges from 23 mpg to 27 mpg combined depending on the model you choose, but with trademark Mercedes convertible features like the “Airscarf” neck warmer system and a power hardtop with available active polarized glass roof, it’s hard to go wrong. If you’re one of the very few buyers who still covets a new SLC, this is your last chance.


The 2020 Mercedes-Benz SLC-Class has aged better than most long-lived sports cars.

The 2020 Mercedes-Benz SLC-Class has remained stylish over the years, thanks to its attention to detail and regular updates. We still like its pert, shapely body, so we give it 7 out of 10.

Sports cars generally have some of the longest product development cycles of any new vehicles because of their low sales volumes, and by the time they’re due to be replaced or cancelled, most look seriously outdated. The SLC-Class has managed to fight this phenomenon even in its final year ever, with forward-leaning proportions and trademark Mercedes details like the LED lights and grille that keep it contemporary.

The interior hasn’t fared quite as well, with a slew of center stack buttons and a small infotainment screen with last-generation software. It reads older, but material quality is great.


The 2020 Mercedes-Benz SLC-Class is best in AMG form, but not as engaging as some competitors.

The 2020 Mercedes-Benz SLC-Class ranges from tame weekend toy to downright joyful sports convertible, but some competitors offer more fun. We give it 6 out of 10 here, based on the SLC300 that more drivers have purchased.

Mercedes’s smallest sports car comes in two flavors, one for the mainstream and one more hardcore. The base SLC300 comes with a 2.0-liter turbo-4, a 9-speed automatic, and rear-wheel drive. This tried-and-true powertrain is good for 241 hp, which is enough to motivate it quickly off the line but not with as much character as the former V-6 in the old SLK350.

The upgraded engine comes in the form of the SLC43 AMG, which uses a twin-turbocharged V-6 with 385 hp. As its improved power figure would suggest, this engine is much quicker and more responsive, thanks to a tougher version of the same transmission. In Sport+ mode—one of five selectable drive modes along with Eco, Comfort, Sport, and Individual—it’s a raucous little sports car, and a Dynamic Handling package improves the suspension, brakes, and rear differential.

Ride quality is good thanks to adaptive dampers, but a short-wheelbase car with big wheels is still subject to plenty of choppiness regardless of how competent the suspension is. While fun, even the AMG version of the SLC isn’t as engaging as competitors like the Porsche 718 or new BMW Z4. It’s a better cruiser than carver.

Comfort & Quality

The 2020 Mercedes-Benz SLC-Class is a mixed bag of great interior quality and subpar storage space.

It’s hard to fault a Mercedes-Benz for quality, but the 2020 SLC-Class is an exercise in compromise. Great seats and materials offset terrible cargo space and limited interior space. We give it 4 out of 10 here. 

Stacked up against the competition, the SLC-Class offers average people space…for a two-seat convertible sports car, that is. Head room is good (infinite with the top down), and knee room is decent, but leg room is in short supply for taller occupants. The trunk is similarly limited, with 10.1 cubic feet of capacity with the top up, but only 6.4 cubes with the hard-folding roof stowed away. There is a backpack-sized storage compartment under the cargo floor.

Interior quality is great, as is Mercedes’s way, with comfortable and supportive seats available with convertible-friendly features like “Airscarf” vents to keep your neck warm. The hard top folds away quickly and can be lowered or raised at speeds slower than 25 mph.


The 2020 Mercedes-Benz SLC-Class has no crash test data but does include some active safety features as standard.

The 2020 Mercedes-Benz SLC-Class has never been crash-tested and never will be due to its low sales volume. Without any data, we can’t give it a score here. 

However, there are extensive safety features made standard and optional on the SLC, including active head restraints and automatic emergency braking with forward-collision warnings. Options include adaptive cruise control, automatic high-beam headlights, blind-spot monitors, and active lane control, but can cost nearly $10,000 all together on the SLC 300.


The 2020 Mercedes-Benz SLC-Class is loaded with features in Final Edition form.

In its final year, the 2020 Mercedes-Benz SLC-Class offers better features than ever and a new special edition to commemorate the end of the line. We give it 6 out of 10.

Every SLC300 gets power-adjustable leather seats, automatic climate control, two USB ports, and a Bluetooth infotainment system with a finicky wheel interface. Automatic emergency braking is also standard, as is a clever active head restraint system. A power folding hard top is also included, and stows away quickly at speeds up to 25 mph.

Options include other safety features, ambient lighting, and a Harman Kardon sound system.

The SLC43 AMG includes performance and appearance extras, as well as a twin-turbo V-6 and LED headlights. Most options are included on the AMG, and sport suspension and an optional handling package make it a bona fide sports car.

For 2020, the two SLC models each get a Final Edition package. The SLC300 is adorned with special gray paint, AMG styling, and unique badging inside and out. The SLC43 Final Edition comes in a brilliant Sun Yellow paint with gloss black trim, as well as AMG accents and Final Edition badging.

Fuel Economy

The 2020 Mercedes-Benz SLC-Class manages average fuel economy for a small convertible sports car.

The 2020 Mercedes-Benz SLC-Class manages moderate fuel economy for a small sports car, even in high-performance guise. We give it 5 out of 10.

With its turbo-4, the SLC300 gets an EPA rating of 23 mpg city, 32 highway, 27 combined while requiring premium fuel.

The SLC43 AMG manages predictably worse with its twin-turbo V-6 and 150 or so additional horsepower, clocking in at 20/29/23 mpg on premium fuel.
