2020 Mercedes-Benz SL-Class Review

  • Smooth ride and comfortable seats
  • Effortless acceleration
  • Folding hardtop still allows for decent cargo space
  • Not as agile as similarly priced luxury convertibles
  • Dated technology features
  • A new Grand Edition model debuts
  • 2020 likely marks the last year of this SL generation
  • Part of the sixth SL generation that was introduced in 2013

The 2020 Mercedes-Benz SL-Class continues the lineage of one of the most iconic touring roadsters ever. It's been eight years since the SL received a full redesign, though, and its age is showing in the face of fresher competitors. To its credit, the SL remains an excellent luxury convertible that delivers high levels of refinement.

Inside, the SL is very much a last-generation Mercedes, lacking the latest MBUX (Mercedes-Benz User Experience) infotainment system and maintaining the dated interior design. It's a functional cockpit, no doubt, but it's missing a lot of the latest tech features and the visual sophistication of current stablemates. If you don't need the latest and greatest features, though, this SL still has the comfort and performance you'd expect.

There are strong rumors that this may be the last year for this Mercedes-Benz SL generation since some poorly disguised test mules have been spotted in Europe. If that's the case, you may want to wait and see what the next SL has in store for us. Otherwise, the newer rivals from BMW and Porsche should easily satisfy.

EdmundsEdmunds' Expert Rating
Rated for you by America’s best test team
The sixth-generation Mercedes-Benz SL has been on sale since the 2013 model year. That's a long time, but Mercedes' consistent updates have kept it from growing overly stale. It's not the fastest or most athletic convertible around, but it is comfortable and practical thanks to a smooth ride, excellent seats and a large trunk. If you're looking for a handsome, understated and comfortable convertible, the SL is worth a look.
We tested the SL 550. Its turbocharged V8 delivers plenty of easy low-end torque. In testing, the SL 550 covered 0-60 mph in an impressive 4.4 seconds. That's not as quick as some rivals, but it doesn't feel any slower on the street.

Driving in the city or passing on the highway feels effortless. Just dip your right foot a little and the SL's V8 emits a warm burble as you're thrust forward with an almost effortless grace. The transmission shifts smoothly and always seems to be in the right gear. And, hey, if you want to make a show of it, the SL is more than willing to light up the rear tires.

Around turns, the SL is capable but feels softer and more imprecise than other sports cars, including the Mercedes-AMG GT. It trades that extra performance for more on-road comfort.
The SL's ride quality is excellent. You feel the road surface, but it's well damped and never harsh. The seats help too. The shape is excellent, striking a great balance between comfort and support. Heated, ventilated and massaging seats are standard, and all three work well. There's even a trick setting you can turn on that automatically increases the thickness of the side bolsters during cornering to help keep you from sliding around in the seat.

The climate control works well too. It runs on the cool side, though that's better than not blowing cold enough. The vents are well placed for even air distribution, and the standard Airscarf (a warm-air vent just underneath the headrest) keeps your neck toasty when the top's down. The SL is fairly quiet on the road too, though it's not as quiet as we expect from a convertible with a retractable hardtop.
The current SL debuted in 2013, making it one of the oldest vehicles in Mercedes' portfolio. That's not to say it feels totally dated, just from a different era. The SL uses Mercedes' old control system, including the outgoing COMAND infotainment system. Though functions such as seat adjustments for lumbar and bolstering are linked to the system, there are buttons for almost all radio and climate control settings — a plus since we find physical controls easier to use.

Despite its low-slung design, the SL is relatively spacious inside. The cabin is wide and offers a good amount of head and elbow room. It's easy to find a comfortable driving position without much fussing. The low-placed windows mean visibility isn't an issue. The SL's rear window is larger than those on most other convertibles too.
This is where the SL really shows its age. It uses last-generation Mercedes-Benz tech, including the infotainment and navigation system. Both lack the features and refinement you'll find in more modern systems, including those in the competition. The SL does come with Apple CarPlay and Android Auto smartphone integration, but the lack of a touchscreen means they're not as easy to use. We also found the sound quality of the Harman Kardon audio system to be subpar compared to systems in other cars at this price point.

The SL is available with plenty of driver aids, including adaptive cruise control, lane keeping assist and blind-spot monitoring. Most are not included as standard equipment, and, as with the infotainment, they don't feel as refined as the aids in new models.
With the top up, the SL's 13.5-cubic-foot trunk is larger than almost anything else in the class. It drops to 8.5 cubic feet with the hardtop lowered, but that's still twice the space of the Lexus LC convertible. The trunk is wide enough for a golf bag and deep enough to fit small luggage.

In the cabin, there's a shelf behind the seat that's good for a couple of soft bags and a hidden bin that's perfect for a purse. The center console and door pockets aren't massive, but they're large enough to be useful for sunglasses or other small items. There's no ideal location to put a smartphone, however.
The SL is available with two engines. The SL 450 uses a turbocharged V6 that gets an EPA-estimated 22 mpg combined. Go with the V8-powered SL 550 and the estimate drops to 20 mpg combined. That's actually pretty good for a V8-powered luxury convertible. We observed an impressive 26.1 mpg from our SL 500 test car on our 115-mile test route.
The SL doesn't feel cheap or overly dated even though it's one of the oldest vehicles in Mercedes' lineup. Some of the buttons and knobs don't have the same premium feel as the ones in newer Mercedes models, but the soft leather and handsome wood trim that adorn nearly every surface make it easy to forgive some of that dated switchgear. Value is decent as the SL 550 includes features such as heated, ventilated and massaging seats, LED lighting, and keyless entry and ignition as standard equipment.

The SL includes a four-year/50,000-mile basic, drivetrain and rust warranty, which is pretty standard for the class. And while we like that Mercedes also includes four years/50,000 miles of roadside assistance, some automakers now include scheduled maintenance.
If you're aiming to stand out or turn heads, you may want to look elsewhere. That's not to say the SL is boring or bland. We like the understated design, and it's handsome without being flashy. Sure, it's been on sale for so long that it doesn't catch your eye like it used to, but it doesn't seem dated either. The exhaust note is killer too, but even that is relatively tame.

The SL is enjoyable to drive, but there are faster and more athletic cars at this price. Where the SL really shines is day-to-day driving or long highway cruises. It's comfortable for hours behind the wheel, and the fat torque curve means giggle-inducing acceleration only takes a small push from your right foot.

Which SL-Class does Edmunds recommend?

As competent as the base SL 450 may be, we recommend stepping up to the V8-powered SL 550 for the full luxury touring experience. It has the right amount of effortless power with a more accessible price than the AMG model. It also has a much more comfortable ride quality. To that, we'd add the Driver Assistance package for more advanced safety features.

Mercedes-Benz SL-Class models

The 2020 Mercedes-Benz SL is a two-seat convertible with a power-folding hardtop that's available in three trim levels based on engine size and output. The base SL 450 is powered by a turbocharged 3.0-liter V6 (362 horsepower, 369 lb-ft of torque) and sends power to the rear wheels through a nine-speed automatic transmission. The SL 550 ups the power with a turbocharged 4.7-liter V8 (449 hp, 516 lb-ft).

Standard features for the SL 450 include 19-inch wheels, a power windblocker, LED headlights and running lights, automatic high beams, automatic wipers, a panoramic sunroof, front and rear parking sensors, forward collision warning and mitigation, keyless entry and ignition, a power trunklid with hands-free activation, selectable drive modes and an adaptive suspension.

Inside, you get dual-zone automatic climate control, sun-reflecting leather upholstery, heated seats, a navigation system, a COMAND infotainment system, Apple CarPlay and Android Auto, two USB ports, and an 11-speaker Harman Kardon sound system with a six-CD changer and satellite and HD radio.

The SL 550 adds AMG-branded 19-inch wheels, an automated parking system, an Airscarf neck-level heater, and ventilated seats with active side bolsters and massage functions.

Most of the SL 550's premium features are optional on the SL 450. All SLs are eligible for mobile Wi-Fi hotspot service and many interior upholstery and trim upgrades. AMG models can be outfitted with carbon-ceramic brakes and carbon-fiber exterior trim. For 2020, a Grand Edition model debuts with 20-inch rear wheels, pre-selected paint and interior trim choices, and diamond-quilted Designo leather upholstery.

2020 Mercedes-Benz SL-Class video

Read Description

NOTE: This video is about the 2017 Mercedes-Benz SL-Class, but since the 2020 Mercedes-Benz SL-Class is part of the same generation, our earlier analysis still applies.

It's been four years since Mercedes-Benz redesigned the iconic SL roadster, so the company picked the 2015 Los Angeles Auto Show to roll out a mid-cycle refresh. The 2017 Mercedes-Benz SL now sports a front fascia that pulls some inspiration from the high-performance AMG GT, with a wider grille, larger air inlets and slightly modified headlights. Inside, the changes are subtle: a new steering wheel, larger infotainment screen and remodeled seats.

[MUSIC PLAYING] ALISTAIR WEAVER: This is Alistair Weaver for Edmunds. Now, consider this for a moment. When is a Mazda Miata not a Mazda Miata? Well, the answer is when it's carrying a Fiat badge, and dubbed a 124. Fiat did a deal with Mazda to use the platform of the wonderful MX5. And to re-clothe it with a bit of Italian flare, which they've done, sort of. Looks are obviously subjective, but to our eyes, it lacks the sort of simple beautiful elegance we might have expected of our Italian cousins. These lights, for example, feel a little bit clumsy. We don't even like it as much as we do the MX5. The Fiat, though, has a very different engine, a 1.4 liter turbo, developing 160 horsepower. It places the two liter naturally aspirated version in the Mazda. That engine's mated to either a six speed manual or like this model, a six speed automatic gearbox. Fiat says they've changed the door casing and played with the instruments. Though to be honest, that's probably no notable change. The rest of the cabin is pure MX5, not that that's necessarily a bad thing. The quality is good, and we like the simplicity of the design, and some of the features like these built-in speakers in the headrest. The only thing we would say, though, is whether the modernist vibe of the aesthetics is at odds with the retro feel of the Fiat's exterior. The 124 is expected to hit US showrooms next summer, priced from around $25,000, bringing it in line with the little Mazda. Which you choose, of course, will come down to personal choice. Me? I'd go with the MX5. But isn't it great that we've now got so many little affordable roadsters on the market?

Mercedes-Benz SL-Class vs. the competition

Mercedes-Benz SL-Class vs. BMW 8 Series

A year after the revival of the BMW 8 Series, the lineup has filled in nicely. There's now a six-cylinder 840i that serves as an entry-level trim to rival the SL 450, at least in regard to price. The newer 8 Series handily beats the SL when it comes to features and technology. It has a slightly smaller trunk than the Benz, but the rear seats fold flat to allow greater cargo capacity.

Compare Mercedes-Benz SL-Class & BMW 8 Series features

Mercedes-Benz SL-Class vs. Jaguar F-Type

The Jaguar F-Type is biased more toward performance and driver engagement, as opposed to the SL's touring luxury. As a result, the Jaguar isn't as spacious or comfortable as the Benz, but it does tend to turn more heads. The F-Type also offers a much more accessible entry-level four-cylinder model. The Jag's smaller trunk limits space for weekend getaway luggage.

Mercedes-Benz SL-Class vs. Porsche 911

For those looking to push performance past luxury touring, the Porsche 911 is a legitimate sports car. At the same time, it's surprisingly comfortable, well-mannered for daily commuting and its interior is appointed with quality materials. The main drawbacks are price (especially with options) and the lack of cargo space.

Should I lease or buy a 2020 Mercedes-Benz SL-Class?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
