What’s new
For 2015, Mercedes' SL lineup adds a new, more affordable V6-powered SL400 model. On the audio front, the standard Harman Kardon system drops to 11 speakers instead of 14, and the six-disc CD changer has been dropped. The SL AMG model's Performance package has also been eliminated, but its limited-slip rear differential, power boost and top speed increase are now standard.
Edmunds says
Though its styling may be an acquired taste, the 2015 Mercedes-Benz SL-Class roadster provides a beautifully executed blend of luxury, technology and performance.

Vehicle overview
You simply can't drive a 2015 Mercedes-Benz SL-Class without being amazed by both the depth and breadth of its skill set. The SL's slick three-piece retractable hardtop offers both the comfort and security of a coupe and the wind-in-your-hair motoring experience of a convertible. Four different engines are available, giving you a range of horsepower from 329 to 621. Then there's the exquisitely detailed cabin and long list of standard features and options. In pretty much every respect, this is a spell-bindingly excellent car.
The biggest news in the SL-Class lineup this year is the introduction of the new SL400 variant that has a V6 engine under that rather prominent hood. A V6? Blasphemy! But with still-respectable acceleration and an as-new MSRP $20,000 below its siblings' six-figure price tags, this new entry-level model promises to open up the possibility of SL ownership to more buyers than ever before. For those with more substantial budgets and more aggressive driving habits, of course, the SL550, and high-performance SL AMG and SL 65 AMG models return largely unchanged.
Expectedly, this elite luxury roadster realm is filled with appealing alternatives. If you want something with sportier handling, the 2015 Audi R8, 2015 Jaguar F-Type and 2015 Porsche 911 would all be better choices. And at the price of the SL 65 AMG, perhaps you'd find the exotic 2015 Bentley Continental GT more appealing. But overall we think it's a very good thing to be an SL driver, and Mercedes' iconic luxury roadster has arguably never been more appealing.
Performance & mpg
The new 2015 Mercedes-Benz SL400 is propelled by a turbocharged 3.0-liter V6 that produces 329 horsepower and 354 pound-feet of torque. The SL550 gets a turbocharged 4.7-liter V8 engine that puts out 429 hp and 516 lb-ft of torque. Both engines come mated to a seven-speed automatic transmission and rear-wheel drive.
Naturally, EPA estimated fuel-economy varies by engine. A standard automatic engine stop-start system helps the SL400 earn a respectable EPA estimated fuel-economy rating of 23 mpg combined (20 city/27 highway), while Mercedes-Benz claims acceleration to 60 mph should take about 5.1 seconds.
The SL550's numbers are a still decent 20 mpg combined (18/25), and in Edmunds testing, the SL550 accelerated from zero to 60 mph in just 4.4 seconds.
Powering the SL AMG is a turbocharged 5.5-liter V8 that pumps out 577 hp and 664 lb-ft of torque. The transmission is a specialized seven-speed automatic with quicker shifts than the standard version. The EPA rates the SL at 19 mpg combined, while Mercedes conservatively projects a 4.1-second sprint to 60 mph.
Finally, the SL 65 AMG comes fitted with a turbocharged 6.0-liter V12 that's rated at an impressive 621 hp and 738 lb-ft of torque, mated to the same specialized seven-speed automatic transmission. In Edmunds testing, the SL 65 AMG sprinted to 60 mph in just 3.9 seconds. EPA fuel economy ratings drop to 17 mpg combined.
Safety
Standard safety features on the 2015 Mercedes-Benz SL-Class include antilock brakes with automatic brake drying, stability and traction control, head- and thorax-protecting side airbags and knee airbags. Also standard are roll bars that automatically deploy, a PreSafe system that can tighten the seatbelts, adjust the seats and roll up the windows if a collision or rollover is deemed imminent, and Attention Assist, a feature that monitors a number of variables and will sound a warning if it detects signs that the driver may be becoming drowsy.
A rearview camera (optional on the SL400) and mbrace2 safety telematics are also standard, the latter of which includes automatic collision notification, an SOS button, stolen vehicle location, alarm notification and remote door lock/unlock.
The main safety option on SL models is the Driver Assistance package (standard on the SL 65 AMG) that includes adaptive cruise control with pre-collision braking, plus active lane-keeping assist and active blind-spot assist, both of which can automatically intervene if sensors detect a potentially dangerous situation.
In Edmunds brake testing, the SL550 came to a stop from 60 mph in 114 feet, which is a bit long for such an expensive performance car with summer tires. The SL 65 was better, with a stopping distance of 108 feet.
Driving
While the long list of techno-gadgetry and top-quality materials go a long way to bolstering the Mercedes SL-Class' "yes, you can have it all" image, driving this luxury roadster seals the deal.
While we have yet to drive the new SL400 model, we can say its SL550 sibling is among the most accomplished sports cars on the road, with an abundance of acceleration, powerful brakes and exemplary handling capabilities, especially when fitted with the available Active Body Control suspension option that all but eliminates body roll. Perhaps more remarkable is the fact that in normal everyday motoring, the SL's smooth ride and sophisticated transmission give it an air of relaxed refinement that is decidedly uncommon in cars with this much performance potential, even the mightiest SL 65 AMG which earned an Edmunds "A" rating.
Those seeking to make a substantial impression on passers-by will likely find themselves lusting for one of the two AMG models, by virtue of their sexier stance and more muscular engines. With these, however, it's mostly style points or bragging rights, as the SL550 offers all the power and handling anyone could realistically ever take advantage of in a street car.
Interior
Of course, the big problem with having everything (or nearly everything) is where to put it. In this regard, the 2015 Mercedes SL-Class is a model of efficient use of space.
For example, Mercedes designers and engineers have managed to pack the passenger cabin with an enormous amount of technology without making the cockpit look overly cluttered. Accessing most of these features is done via the COMAND system's console-mounted knob, which calls up menus on the 7-inch center display. Worthy of special mention are unique features like the optional SplitView central display that allows the driver and passenger to see their own unique content like the nav system's map and a DVD movie simultaneously.
In more practical terms, head- and legroom are abundant, and the 12-way power-adjustable seats offer a particularly large amount of fore-and-aft travel which, combined with the power tilt-and-telescoping steering wheel, makes it easy for a wide range of individuals to find an ideal driving position. The sun-reflective perforated leather upholstery offers heating, ventilation and a massage function that makes the SL an excellent road-trip machine. Add the power mesh wind blocker that rises from behind the seats and the AirScarf neck-level heating system and it becomes possible to enjoy open-air motoring in conditions where owners of lesser convertibles feel compelled to put the top up.
When it comes to loading up for a trip to the golf course or a romantic weekend getaway, the trunk offers 10.2 cubic feet of storage with the roof up and 7.2 cubic feet with it folded down (there's also a significant amount of storage behind the seats). Accessing the trunk is made easier by a hands-free power opener that can be activated by waving a foot under the rear bumper.
2015 Mercedes-Benz SL-Class models
The 2015 Mercedes-Benz SL-Class is a two-seat, retractable-hardtop convertible that's now offered in four trims: SL400, SL550, SL AMG and SL 65 AMG.
The new entry-level SL400's list of standard features includes 18-inch wheels, an adaptive suspension, adaptive xenon headlights, automatic high-beam control, front and rear foglights, LED daytime running lights, automatic wipers and a see-through power-folding hardtop. Inside you'll find dual-zone automatic climate control, perforated leather upholstery, 12-way active multicontour power-adjustable seats, heated seats, memory settings, a power-operated wind blocker panel, an auto-dimming rearview mirror and cruise control. Technology features include Bluetooth phone and audio connectivity, Mercedes' COMAND electronics interface and mbrace telematics systems, a navigation system and an 11-speaker Harman Kardon surround-sound audio system with a CD player, satellite radio, HD radio and USB/iPod interface.
The most notable option on the SL400 is a Premium package that bundles a rearview camera, an automatic parallel parking system, ventilated seats with massage, the AirScarf neck-area heating system, keyless entry and ignition and a power trunk closer. The SL550 includes all of the above, and adds a more powerful V8 engine and front and rear parking sensors.
Both the SL400 and SL550 are also available with a Sport Wheel option package that includes 19-inch alloy wheels, larger front brakes with painted calipers and drilled rear brake discs, plus a sport steering wheel accented with perforated leather trim and silver shift paddles.
The high-performance SL AMG features an even more powerful V8 engine, a limited-slip rear differential, 19-inch alloy wheels, Active Body Control suspension with more aggressive tuning, upgraded brakes and a higher top-speed limiter. The cabin gets illuminated door sills, upgraded leather upholstery and an AMG Performance Media system that can display G-forces and other related information.
A Driver Assistance option package that includes adaptive cruise control, a blind-spot warning system and active lane-keeping assist is available on the SL400, SL550 and SL AMG.
The top-of-the-line SL 65 AMG gets a V12 engine, 19-inch front and 20-inch rear wheels, the contents of the Driver Assistance option package, a panoramic roof with a Magic Sky feature that darkens the tint at the touch of a button, soft-closing doors, a night-vision infrared camera system, a split-view front entertainment system and a premium 12-speaker Bang & Olufsen audio system. Both the AMG models can also be optioned with an exterior Carbon Fiber Trim package that includes a carbon-fiber front airdam, mirror covers and rear spoiler. The AMG High-Contrast Styling package includes distinctive 19-inch front and 20-inch rear alloy wheels, a gloss black hardtop and rear spoiler, black chrome exhaust tips, a performance steering wheel and unique interior trim. Carbon-ceramic high-performance brakes are also available.
Stand-alone options include 19-inch alloy wheels, upgraded designo leather upholstery and interior trim, plus many of the features found on the two AMG models.

2013 Mercedes-Benz SL-Class SL550 2dr Convertible (4.7L 8cyl Turbo 7A)
I was approached not long after purchasing the SL by a gentlemen who has owned a good number of exotic and sports cars. In his words, "the SL is what all cars want to be when they grow up". I could not agree more. You may find a sportier car or two, a better looking luxury car, or a car that covers great distances in extreme comfort; but the SL does all of that, and more. This car … loves to eat road, top up is like a coupe; solid and silent. Top down is like, well, a high performance convertible. The SL has become our grand touring car and it has proven itself to be most worthy in every instance. We went the CPO route, which lessens the pain of the check book, but provides solid Mercedes warranty and support. Drive the other contenders, then drive an SL. It continues to amaze with it's power, torque, ease of operation, and rock solid build quality. And while the looks may be contentious to some, this car draws admiring looks in even the most discerning crowds. It does not disappoint. 2019 UPDATE: the car is now six years old, and has over 40,000 miles, and still makes me smile while I drive. It has become our weekend touring GT car; delivering performance, style and reliability. In many trips of over 1,000 miles, the car is a joy to drive, on the interstate or the back roads. My only area of issue has been the AMG wheels; as I have had two that cracked; I have replaced them with an aftermarket set with great success. It would appear that the next-gen of the SL will be on a shared modular platform with other models. That would make the R231 the last of the bespoke SL's; so this vehicle is destined to be in our garage for a long time. Looking for a competent coupe / convertible? This is a great choice.

2013 Mercedes-Benz SL-Class SL550 2dr Convertible (4.7L 8cyl Turbo 7A)
For my money, the best all-around way to spend money on a used convertible.
Any car I mention in this review I have owned or driven for an extended period of time. I have owned well over 100 cars. I bought my 2013 SL550 2 years old with ~45,000 miles.
General: Just to provide some context to how I think, I have a budget for cars, it is not tight, but it is not crazy to me, to others … including my wife, it borders on insanity. I don’t buy new because I don’t want to pay the new depreciation. I sometimes buy carefully inspected, and well repaired branded title cars (I don’t suggest this for others, if you don’t take the time to learn the game you will lose your shirt, maybe your pants, and sometimes your shoes).
I will probably never own the likes of a Bentley, Rolls, Ferrari or McLaren, and couldn’t pretend to play in the world of Pagani, even if I gave up my entire net worth. Although I really like them, I can never seem to justify the relative cost for a 911 (at the age I buy them, generally 2 to 5 years old) – maybe if I kept my cars longer.
For me, this SL550 is my favorite car that I have owned to this point. For the first time I could see myself trading this for a newer version of the same car. When I change this car, if I change it for a different car, it will likely be an S class cabriolet. In terms of SLs, I have owned a 1996 SL500 (great car!) and a 2004 SL55 AMG (not so great, but maybe the specific example I owned).
Crazy performance: If visions of track days dance in your head – buy a corvette Grand Sport or Z51 with magnetic ride. In my opinion, if you are anything short of a professional or every weekend armature, you will never be able to competently test the limits of the Corvette, and you can pick up a manual C6 for practically nothing now days. Budget no object? Knock yourself out with something more exotic. Porsche cocksters . . . err . . . Caymans are also fantastic for track days if you are willing to give up grunt for precision.
Reasonable performance: When it is dry, with good tires, there isn’t a road that I can’t easily, and safely, send myself to jail on with the SL550. I can generally take sweeping canyon corners, easily and safely, at 2+ the posted limit while staying planted. Very tight corners, same thing, but I admit this is the one place where this generation SL feels its size and weight. The rear end doesn’t predictably kick out like a gen3 RX7, but what does? Plus, the electronic nanny’s will stop it anyway, which is probably a good thing. Steering is lighter than a sport car, and not as communicative as some, but for public roads, any public road, absolutely more than competent. There is noticeable turbo lag under certain circumstances.
Styling: I am tired of reading about how ugly the exterior of latest couple of generations of the SL are. I like them, but styling is subjective, if you hate the styling, I assume you aren’t reading this. In my opinion, the interior is absolutely top notch in quality and aesthetics, and most of the reviews seem to agree with me. Not spartan, and not busy. Things are accessible and intuitive. I have a maroon and black interior color combination; with white exterior, and I really like it, again maybe the best of any car I have owned.
Comfort: Not going to beat it at any price.
Budget/reliability: If budget is no object, and you are willing to pay twice as much for an incrementally better ‘drivers’ car, with similar performance, go for a 911 S. Repairs aren’t cheap, after 25,000 miles I have found reliability to be on par with similar cars, but there will be repairs, and repairs will be on the pricier side of ‘normal’.
Driving: I have never owned a car that is more enjoyable for a weekend road trip. As I have said, but I will repeat, nothing is more comfortable, especially after several hours. If I hit a canyon, I can set sport mode, stiffen the suspension and the steering gets a little heavier, the throttle and shifts are downright snappy, and the car stays nearly as flat as a corvette with magnetic ride in sport in the corners. There is also a nifty feature that stiffens the seat bolster on the side you are turning into to keep you in your seat without cramping you. When the freeway straightens out, turn on the massage and relax. I have heard complaints about the sound system, but for me it is literally the best sound system I have anywhere, including any room of my home.
With all of the climate options (heated seats, air scarf, and very good heater) my wife and I have traveled with the top down, on sunny days, but temperatures well below freezing, and were completely comfortable.
Final Word: I love this car! I accept that when a car is a ‘general’ car, it can lose its ‘purpose’. The SL550 isn’t a Ferrari, or even a Corvette. It is a car that serves nearly every purpose for 2 people driving anywhere for less than a week, and does everything much much better than is ‘necessary’.
First SL550 but third Mercedes Benz

2013 Mercedes-Benz SL-Class SL550 2dr Convertible (4.7L 8cyl Turbo 7A)
If you are a Mercedes enthusiast and considered buying an SL550 for your retirement years, don't hesitate but choose the 2013 or newer. The improvements with this new redesign starting with the 2013 are well worth the extra it costs. It is a fantastic car and worth every penny. I have no regret purchasing mine and plan to keep it as long as I can drive, and then park it in the garage … and just look at it.

2015 Mercedes-Benz SL-Class SL 550 2dr Convertible (4.7L 8cyl Turbo 7A)
This is my dream car. I love that its fast as lightning , beautiful to look at and the way it handles, but does it all in an effortless, professional way. It is so packed with luxury but is still a masculine car. do we really like to get punished in a Porsche just because we want to drive in a sports car? Maybe getting soft in my 40's but I like a quiet, smooth, UN-jarring ride mixed … with massive power and agility. I'm not competing on a race track. anyone saying this SL is anything less than totally sophisticated understated and beautiful is maybe upset that they don't own it.
Update: excellent reliability still just as beautiful as the day I bought it.
We have a limited number of reviews for the 2015 Mercedes-Benz SL-Class, so we've included reviews for other years of the SL-Class since its last redesign.
