What We Like

Bulletproof construction with a seemingly endless list of luxury features; satisfying performance across the lineup; hard to beat the SL-Class' heritage and brand equity

What We Don't

Lacks the visual appeal of earlier SL models; hardtop limits trunk space when folded

Overview

What's New in the 2015 Mercedes-Benz SL 400?

The entry-level SL400 debuts with a turbocharged V6 engine; it's the first 6-cylinder SL in the United States since 1997. Otherwise, the SL sees just minor equipment adjustments this year. 

Which SL 400 is the Best?

If the SL were just a little prettier to look at, it would be a virtually flawless luxury convertible. Even with that somewhat bulbous nose in the mix, it's still one of the finest automobiles on the planet. Find a Mercedes-Benz SL-Class for sale

 

How Much Does a 2015 Mercedes-Benz SL 400 Cost?

The 2015 Mercedes-Benz SL-Class is available in SL400, SL550, SL63 AMG and SL65 AMG trim levels.

The SL400 ($84,925) includes standard amenities such as 18-inch alloy wheels, xenon headlamps, fog lamps, LED accents in the front and rear, adaptive suspension dampers, a power hardtop with a panoramic glass roof, leather upholstery, active power seats with memory, the COMAND infotainment system with navigation, Bluetooth and a Harman Kardon audio system with USB connectivity.

The SL550 ($107,825) steps up to the 4.7-liter V8, plus keyless entry/start, massaging seats, neck-level heating vents, an advanced parking system with self-parking capability and a power trunk lid.

The SL63 AMG ($148,975) boasts the 5.5-liter V8 and all manner of styling, handling and interior upgrades befitting of its AMG status. Highlights include 19-in AMG wheels, special dampers with active roll resistance (known as Active Body Control or ABC), big brakes and performance telemetry.

Ultimate SL-Class performance comes from the SL65 AMG ($217,475), which features the only V12 in the lineup, plus 20-in rear wheels, a Magic Sky Control roof that turns from transparent to opaque on command, power-closing doors, an enhanced infotainment display and Bang & Olufsen audio.

Options include some of the higher trims' standard features, plus carbon-fiber trim (exterior and interior), black chrome trim and carbon-ceramic brake rotors.

The SL's trunk is pretty roomy by roadster standards, measuring about 10 cu ft. with the top up. Folding the top takes a big bite out of that space, though -- three cubes, to be exact -- so remember not to go al fresco if the boot's fully loaded.

Safety

Is the 2015 Mercedes-Benz SL 400 a Safe Car?

Mercedes-Benz claims that the 2015 SL is "the world's safest convertible." Along with side and knee airbags, there's a pop-up roll bar, a driver-drowsiness monitor and the company's pre-collision system, which tightens seat belts and primes the brakes. On the options list are a blind spot monitoring system, active lane-keeping assist and adaptive cruise control with automatic emergency braking.

Competition

2015 Mercedes-Benz SL 400 vs the competition

2016 BMW 6 Series Convertible -- The drop-top 6 Series features four seats and a vinyl roof rather than a hardtop, but it's comparable to the SL in terms of power and technology.

2015 Jaguar F-TYPE Roadster -- Jaguar's first genuine sports car in years is stiffer and louder than the SL-Class, but that might be a good thing.

2015 Porsche 911 Cabriolet -- The open-air 911 has a soft-top, just like the BMW and Jag, but it also has timeless beauty on its side, not to mention the unique rasp of its flat-6, rear-mounted engine.

Used Bentley Continental GTC -- If you want to activate full baller mode, you can find a lightly used Bentley drop-top for the price of an SL. Just make sure you have some kind of warranty.
