2015 Mercedes Benz SL-Class
2015 Mercedes Benz SL-Class

New for 2015

The Mercedes Benz SL-Class adds a twin-turbo 3.0-liter V-6 to the model line, creating the entry-level SL400 for thousands below the least-expensive SL550. The SL-Class remains otherwise unchanged for the 2015 model year.

Vehicle Overview

The Mercedes Benz SL-Class Roadster is an iconic two-seater that combines the luxury of the S-Class with a sporty grand-touring nature. The SL-Class fits above the SLK-Class and below the outgoing, high-performance SLS-Class in the Mercedes-Benz lineup.


The 2015 Mercedes Benz SL-Class roadster is a hardtop convertible that pairs a range of capable engines with a seven-speed automatic and rear-wheel drive. Luxury and options abound, as the SL takes cues from the S-Class, resulting in a great grand tourer.

Notable features on the 2015 SL include a semi-active suspension with active damping, torque vectoring braking, an engine stop-start system, active body control, a power retractable hardtop (raises/lowers in 20 seconds, but must be stopped), Magic Sky Control (can make the glass roof transparent or opaque via electrical current), adaptive HID headlights, adaptive high beam assist, Attention Assist (if the driver is falling asleep system will alert the driver and suggest a break), Magic Vision Control (sprays washer fluid from the windshield wipers, eliminating vision-obscuring haze and the possibility of overspray with the top down), adaptive cruise control, blind spot assist, lane keep assist, active parking assist (can assist going into and out of parking spaces), heated/ventilated seats, Airscarf (warmed air is blown on the neck/head/shoulders), and a massaging seat function.
Also of note, we found the standard Harman Kardon audio system to be superior to the expensive Bang & Olufsen premium audio system.
The 2015 Mercedes Benz SL-Class has not been crash tested by the NHTSA or the IIHS.

What We Think

The iconic Mercedes Benz SL-Class roadster makes an excellent touring car, but not a good sports car. In a Driven Review of a 2013 SL63 AMG we said, “The SL63 AMG is not a track car and it’s not supposed to be. The AMG SL’s character makes further sense when you remember that Mercedes now offers the SLS AMG Roadster for those looking for a more focused (and normally-aspirated) two-seat convertible.” We preferred the steering of the SL63 to the standard SL550 because of the base car’s variable system, which would change the steering ratio in a non-linear fashion as the wheel was turned past 5-degrees. Handling was impressive and we noted, “No matter what the setup, the SL63 is not an overly communicative sports car. It’s incredibly fast and extremely capable but slightly too synthetic as it goes about its business at a very rapid pace.”
In a Driven Review of a 2013 Mercedes Benz SL550 we looked inside and said, “This is Benz's most glamorous and well-constructed interior. It's very roomy, too, feeling as spacious as a full-size luxury sedan that happens to be missing the back of its cabin. The seats are as comfortable as they are attractive, with shoulder supports that cascade down from the headrests like the collar of Cruella de Vil's puppy-fur overcoat.”
Our one complaint with the sixth generation of SL Roadsters is the styling. We said, “It lacks the visual punch of a $100,000 jewel, too closely resembles the cheaper SLK, and is saddled with disjointed front, rear, and sides that look like they were designed by three different people. That is because they were, in fact, designed by three different people.” Interestingly the SL63 gets a combined fuel economy rating of one less mpg versus the SL550, (16/25 mpg vs. 17/24 mpg), which leads us to recommend getting the AMG. With gas savings like that, who can say no to more than 100 extra horses?

2016 Mercedes Benz SL550 Special Edition Mille Miglia 417 Front Three Quarter 02
Sixty years ago, drivers John Fitch and Kurt Gessl piloted a 1955 Mercedes-Benz 300SL to a fifth-place overall win at the famed 1955 Mille Miglia race, finishing ahead of an entire field of purpose-built race cars and sports cars.The 300SL ran with the “417” on its flanks as the race registration number, and just so happened to begin the race at 4:17 in the morning. To commemorate this important anniversary in Mercedes’ history, a special edition SL-Class roadster is being offered for modern-day customers. The Mercedes-Benz SL-Class Special Edition “Mille Miglia 417” adds a healthy dose of visual flair to either an SL400 or SL-Class roadster.
Mercedes Benz Sl63 World Championship Edition Black And White Front Three Quarters
The latest special edition of the Mercedes-Benz SL convertible is a sort of victory lap for the brand, as it celebrates the Mercedes-Benz Formula 1 team’s 2014 world championship win. Two versions of this limited-run SL, each said to be created by drivers Lewis Hamilton and Nico Rosberg, will be sold at quite a price premium to an exclusive set of buyers.

When it comes to cars, what's in a name? In today's diverse automotive universe, a car's nameplate can totally change meaning depending on the prefixes or suffixes attached to it. Take acronyms like SRT, EV, and AMG, for instance: these simple letter combinations can turn workaday economy cars or mainstream SUVs and transform them into something wildly different.
2014 Mercedes Benz SL550 Passengers Above View In Motion
The entry price for Mercedes-Benz’s most prestigious droptop gets considerably lower for 2015 with the addition of the new SL400 model that’s powered by a turbocharged V-6 engine. This 329-hp version of the SL starts at $84,925, more than $20,000 less than the V-8-powered SL550 (pictured) that previously sat at the bottom of the SL model range.

The new twin-turbocharged V-6 engine that debuted recently on the redesigned Mercedes-Benz C-Class and ML-Class will find its way into the 2015 Mercedes-Benz SL400 as well, creating a new entry-level model for this hardtop convertible. The SL400 model will join the existing SL550, SL63 AMG, and SL65 AMG models, presumably at a lower price point than the $107,825 SL550.
