Our Take

from the Cars.com expert editorial team

What Is the 2019 Mercedes-Benz SL-Class?

The two-seat Mercedes-Benz SL-Class, a retractable-hardtop convertible, is constructed mostly of aluminum and is offered with a choice of V-6 or V-8 power. The base SL450 gets a 362-horsepower, twin-turbocharged 3.0-liter V-6 engine, while the SL550 uses a 449-hp, twin-turbo 4.7-liter V-8; a handcrafted 577-hp, twin-turbo 5.5-liter V-8 powers the AMG SL63. All models have rear-wheel drive. The SL competes with the BMW 6 Series.

What’s New on the 2019 Mercedes-Benz SL-Class?

The AMG SL65 version, which was powered by a V-12 engine, has been discontinued. The returning models receive no significant changes.

What Features in the 2019 Mercedes-Benz SL-Class Are Most Important?

The SL comes with features not found on many other cars. The power-retractable roof can be raised or lowered while the car is moving at up to 25 mph. When the top is up, an available panoramic glass section can automatically change from dark to transparent. An available active suspension adjusts to reduce body roll in corners and lowers automatically at high speeds.

Should I Buy the 2019 Mercedes-Benz SL-Class?

The SL roadster has been coddling Mercedes customers for more than 60 years, and though it doesn’t rank in the same performance league as the Porsche 911, the SL550 and AMG SL63 are hardly boulevard cruisers. They offer elegant surroundings and enough verve to keep most drivers entertained.

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
