2017 Mercedes-Benz SL-Class Review

It's been a few years since the iconic SL roadster's last redesign, so this is a perfect time for a little nip and tuck. The 2017 Mercedes-Benz SL-Class gets a significant styling refresh that incorporates the company's latest design language, making it look sleeker and more modern. The improvements aren't just skin-deep, though, as the base SL450 (previously the SL400) and SL550 both get power increases and a new nine-speed transmission. Add a smattering of extra standard features, and you've got a compelling case for upgrading to this year's model.

With these improvements, the 2017 Mercedes-Benz SL-Class reaffirms its position at the top of the luxury-roadster hierarchy. Few cars can compete with the SL's intoxicating blend of performance, luxury, class and refinement. Even the base V6-powered SL received one of the strongest Edmunds "A" ratings we've ever awarded. Step up to V8 or V12 power, and you'll enjoy the same superb fundamentals along with even more silky-smooth thrust.

As good as this Mercedes roadster is, it's not the only choice. The Porsche 911 is a fantastic alternative, though it's definitely more of a sports car than a touring car. The same holds true for the new Audi R8 and Jaguar F-Type. At the top of the range, the $200,000-plus AMG SL65 could be cross-shopped with the exquisite Bentley Continental, too. But the bottom line is that the SL-Class lineup is an embarrassment of riches. When so many things are so right, you really can't go wrong.

Standard safety features for all 2017 Mercedes SL-Class models include antilock brakes, traction and stability control, side airbags, side curtain airbags, knee airbags, a drowsy driver warning system, a forward collision warning system with automatic emergency braking, Mercedes' Pre-Safe system (cinches seat belts and raises the windows when an imminent collision is detected), Mbrace emergency telematics, pop-up roll bars and active head restraints.

A rearview camera is standard on the SL550 and above (optional on the SL450). The SL65 comes standard with the otherwise optional blind-spot monitoring, lane keeping assist and the Pre-Safe Plus system that detects potential rear collisions, engages the Pre-Safe protection measures and can apply the brakes to prevent secondary collisions.

The 2017 Mercedes-Benz SL-Class is a two-seat convertible with a power-folding hardtop. There are four trim levels: SL450, SL550, AMG SL and AMG SL65.

Even the "entry-level" SL450 delivers smooth and potent power that will quicken your pulse, while the new nine-speed automatic is unobtrusive yet gratifyingly responsive. Add in strong brakes and confident handling, and it's easy to see why the V6-powered SL is so highly regarded by our editors. Choose a V8 or the V12 and you'll have still more capability, especially when Active Body Control (ABC) is specified. ABC now boasts a "curve tilting function" that actually tilts the car into a corner rather than allowing it to roll to the outside.

As strong as the SL-Class is on performance, it remains a comfortable touring car at its core. If you're looking for a sportier alternative, the AMG GT should hit the spot. For most, however, the class and refinement of the Mercedes-Benz SL will make it hard to beat.

The 2017 Mercedes-Benz SL-Class is built more for comfort than all-out performance. Taller and larger drivers will find an abundance of space, and the wide range of seat adjustments ensure that virtually all occupants will find their ideal position. The multi-contour seats (standard on the SL550 and above) further enhance comfort with adjustable side bolsters for lateral support and massage functions to alleviate fatigue on longer drives. On warmer days, the sun-reflective leather and cooled seats will keep you from overheating, and when the weather turns, the Airscarf will keep you comfy with a warm breeze on the back of your neck.

The SL also benefits from the available Magic Sky glass roof that allows you to enjoy a clear panoramic sunroof or transition to dark-tinted glass at the flip of a switch. Obviously, there's still the allure of open-top touring, and now the power-folding top can be operated at speeds up to 25 mph. Buffeting and wind noise are kept in check by the power windblocker, allowing you to have a conversation on the highway without raising your voice.

Materials quality is excellent throughout the cabin, meeting expectations for a car in this lofty price range. As with other Mercedes vehicles, the COMAND infotainment system takes a little time to get acquainted with, but after a short while the menu structure begins to make sense.

Convertibles with folding hardtop roofs typically sacrifice quite a bit of cargo space when the top is down, but the SL manages to provide a decent 8.5 cubic feet of capacity. With the top up, there's a full 13.5 cubic feet available. The hands-free trunk opener (standard on the SL550) makes loading easier by popping the trunk with just a swipe of your foot under the rear bumper.
