2014 Mercedes-Benz SL-Class Expert Review

By

KBB Expert Rating: 7.2

Beloved by Hollywood and Silicon Valley alike, the Mercedes-Benz SL is iconic as both a classic roadster and as a symbol of success. The latest SL-Class was revamped just last year with fresh design, lighter materials and gee-whiz technology to create a hardtop convertible that remains true to its "Sport Lightweight" nomenclature. Convertible editions of the Jaguar XK, Porsche 911 and BMW 6 Series offer varying degrees of performance, panache and luxury in the SL's 6-figure territory, but few can match this Mercedes' level of prestige. And thanks to its well-insulated retracting hardtop, twin-turbocharged V8 and abundance of innovative features, the 2014 SL-Class remains a sublime grand touring car.

You'll Like This Car If...

If you can afford the SL's $100,000-$200,000 price, you'll be treated to a 2-seater with impeccable craftsmanship, thunderous power and cutting-edge technology, not to mention the intangible nature of having a $100,000-$200,000 Mercedes-Benz. Need more justification? Think of the SL as two cars in one: coupe with the hardtop up, roadster with it down.

You May Not Like This Car If...

If you're all about raw performance, you'll find more seat-of-your-pants thrills in a Porsche 911 or the new Jaguar F-Type. While neither can match the 621 horsepower churned from the SL65 AMG's V12 engine, they can slice roads like a steak knife through butter.

2014 Mercedes-Benz SL-Class Low/wide front photo What's New for 2014

With the Mercedes-Benz SL-Class being all-new last year, it carries over unchanged for the 2014 model year.

Driving the SL-Class

Driving Impressions Because the 2014 Mercedes SL's electromechanical Direct-Steer system filters out more road feedback than necessary, you won't experience the razor-sharp handling of, say, a Porsche Boxster. Then...

... again, Mercedes' hardtop convertible doesn't aspire to be a Porsche Boxster, and even with the SL's eyes on comfort, you'll still find an engaging driving experience when a twisty road calls. Should you decide to answer with your right foot, you'll enjoy tenacious grip with the Active Body Control system that virtually eliminates body roll. The system is available on SL550 models and standard on the AMG versions. Braking power is also more than adequate, especially with the carbon-ceramic setup on AMG models. At $12,625, they cost nearly as much as an economy car. Also not surprising should be the 2014 SL-Class's monstrous power, sent to the rear wheels via a slick 7-speed automatic transmission. Ranging from 429 horsepower to 621, rest assured that merging isn't a problem.

MBRACE2
The 2014 SL-Class touts Mercedes-Benz's newest-generation information and entertainment system, dubbed mbrace2. Even if you can't embrace its spelling, you'll find much usefulness and enjoyment from the system's 24-hour concierge assistance, embedded emergency services and access to mobile apps such as Facebook and Yelp.


MAGIC SKY CONTROL
Dilemma: It's sunny and you have a beautiful convertible, but you also have a business meeting and mustn't ruffle your hair. The solution for catching rays while maintaining your perfectly coiffed hair is Magic Sky Control, which magically changes the SL's panorama roof from dark to clear and – should it get too sunny – vice versa.

The 2014 Mercedes-Benz SL-Class remains without equal in opulence and spaciousness among 2-seat roadsters. With the hardtop roof in place, even 6-footers will enjoy ample headroom and legroom. Intrinsic to the cabin's appeal are the top-notch materials and exacting construction long appreciated in any car wearing Mercedes' 3-pointed star. Among impressive features is the aforementioned Magic Sky Control. Storage space is laudable for a roadster. With the top up, the 2014 Mercedes SL has 13.5 cubic feet, and with it down offers 8.5 cubic feet. You can pick up your friend at the airport, and she won't have to cradle luggage in her lap.

Exterior

The SL's recent design revamp is at once evolutionary yet highly respectful of a heritage that dates to the 1950s. At roughly 182 inches in length, the Mercedes-Benz roadster is over 10 inches shorter than the 4-seat BMW 6 Series convertible, yet the SL has considerable presence. Its finely contoured sheetmetal, bright bi-xenon headlights with LED accents and fender-filling 18-inch wheels (19 inches on AMG models) add up to a modern take on a classic sports-car aesthetic. As a purpose-built hardtop convertible, the SL looks as elegant with its top up as it does with it down.

Notable Equipment
Standard Equipment

As should be expected in a car costing six figures, the 2014 Mercedes-Benz SL-Class is generously equipped even in its SL550 "base" form. Standard on that model are heated and ventilated 16-way power seats with massage function, Mercedes' Airscarf neck-level heating system, driver-selectable adaptive suspension, rearview camera and a 10-speaker harman/kardon surround-sound audio system with navigation, real-time traffic and digital music storage via an integrated hard drive. A hands-free system lets you open the trunk by waving your foot underneath. Besides their more powerful engines, the SL63 and SL65 AMG models feature AMG styling adornments along with a performance-tuned suspension, exhaust system, brakes and transmission.

Optional Equipment

Mercedes offers plenty of features for the SL-Class to make it more opulent, more potent and safer. Highlights include a Bang & Olufsen audiophile system, the Magic Sky Control roof tinter (both standard on the top-line SL65 AMG), and wood-and-leather steering wheel. The Driver Assist Package (also standard on the SL65) bundles a slew of safety features that include blind-spot monitoring, lane-departure warning and radar-based cruise control. The mid-level SL63 AMG model offers a performance package that increases engine power, raises the top speed and adds a limited-slip differential. For those seeking the most customization, Mercedes offers the designo commission process.

Under the Hood

To say all 2014 Mercedes SL roadsters are potent would be an understatement. With 429 horsepower and a 0-60-mph time of 4.5 seconds, the SL550's twin-turbo V8 will get you wherever you need in a hurry. Step up to the SL63 AMG, and its larger twin-turbo V8 will deliver that performance benchmark in 4.2 seconds. At the top of the SL food chain is the SL65 AMG with its twin-turbo V12. Its 621 horsepower can rocket the roadster to 60 mph in 3.9 seconds. All SL models direct power to the rear wheels through a 7-speed automatic transmission, with AMG models sporting a quick-witted Speedshift version. To improve city fuel economy, every SL-Class includes a start/stop function. The SL65 is still not immune to a gas-guzzler tax, though.

The 2014 Mercedes-Benz SL550 has a starting Manufacturer's Suggested Retail Price (MSRP) of over $107,000, with the AMG-tuned SL63 and SL65 beginning around $148,000 and $216,700, respectively. Options can increase these prices by the thousands. Convertible rivals such as the Jaguar XK, BMW 6 Series and Porsche 911 start under $100,000, while the Audi R8 convertible begins at roughly $130,000.

Cons: "Not for winter, hard to get into"

"Even with Pirelli summer tires I could get my 2003 SL55 up the slight incline into my garage with a running start especially if I turned off the ESP when there was some snow and ice in the driveway. With the replacement 13 SL550 and Bridgestone run flats summer tires, be prepared with two strong pushers and a bunch of cinders to get it back in the garage if you are dumb enough to try driving it in the winter. Also without the easy entry feature that my old SL55 had, its not too easy for the driver to get into when the top is on. Otherwise it is superior in every way to my 2003 SL55 which I owned since fall of 2003. All the electronics are up to date and look like they will be trouble free. The car is a beast as far as handling and acceleration just like my 03 SL55 but also gets 18 mpg in city driving, not 12mpg. Be sure to get the bigger AMG wheels which also come with bigger brakes. Wish it had a heated steering wheel option, but on the other hand its undrivable in the winter. All in all a great car, but not if you live in snowy climes and don't have a winter car. It will have to be stored for the winter."

"In the early 70s I owned a high-performance Mustang. Until just recently, I couldn't get a car that tickled my fancy like it did. Power to weight ratio and handling went out the window. After experiencing the SLK and then the SL 550 I can report that my humor has been restored. While not a 7 Liter car, this Mercedes is absolutely wonderful. Even my sports car driving (Miata) girlfriend is impressed, commenting favorably on the handling of the SL. One of the main benefits is improved interior room over what I experienced in the SLK. A properly designed roadster in my opinion. You will be inspected by the local Highway Patrol for your speed settings. Fortunately if you drive exactly the speed limit they don't seem to bother you. I am thankful for the precise speed gauging in the SL."

"Having just traded in my 2011, his is my 2nd consecutive MB SL550. The 2014 is a vastly improved car in many, may ways- it drives better, handles better, feels more solid and has more power. Candidly, the 2014 feels like a far superior vehicle and makes it almost impossible to believe that I had been driving the same car for 3 years. There are a few knocks however. First, the styling takes some getting used to. The nose of the car maintains a decidedly MB look however the rear and rest of the car feel somehow disconnected and somewhat pedestrian. The rear of the car could be almost any luxury brand based on looks alone. Next, the interior of my car has a pretty bad odor to it. From my past experiences, I realize that MB doesn't not have the typical "new car" smell but this vehicle almost smells like a drunk mechanic. I've had the car for less than a week and have an air freshener in the car which is a tragedy given the six figure price of the car. I have reached out to the dealership and am waiting for their reply. Also, the interior redesign, which is far superior to the 2011 also comes with sacrifices. Fit and finish are amazing. The ridiculous cup holders from the old model have been addressed. The seats are on a whole new level comfort-wise. However, the storage spaces are terrible. The fantastic door compartments of the 2011 are gone. Beyond the glove box, the dash has no storage. And, the center console, which was redesigned to make room for cup holders, offers a storage box that opens at the elbow, making it nearly impractical to use as a driver. It makes the day to day driving experience a little frustrating. Finally, the audio system is far superior to that of the 2011, however, the centering of the surround is WAY forward in the car. It sounds like someone is singing from under the hood directly in your face. This hinders the true magic of the new system, which includes the best bass EVER. The SL line of MB is without question their pinnacle of their brand. Driving the 2014 feels like driving a completely new type of car, which isn't a bad thing at all even if it is a quantum leap over the same car. Most of the shortcomings of the car, including the exterior design, are ones that will improve over time, however, the smell and creature comforts you expect in a car of this price are completely lacking and, at times, make me wonder if I have made a mistake in committing to a second SL."
