2018 Mercedes-Benz AMG SL 63 Complete In-depth Review & Buying Guide

Mercedes-Benz created the SL Class back in 1954 to be a grand touring car by the German manufacturer. Since then there have been numerous iterations of the SL, each better and crazier than the last. Then there is the AMG sticker, which adds more horsepower to the mix. The 2018 Mercedes-Benz AMG SL 63 Roadster carries the same AMG animal inside.

Expert Review


CARHP Editorial September 24, 2018


For $152,850, you can have a 5.5-liter 577 horsepower V8, which is sure to always attract attention from the general crowd. The car looks just as good at speed as it does when standing stationary on a traffic signal, on in front of the valet line. Its dual personality makes it a perfect tool for a glamorous day to work and a glorious evening on the track.

2018 Mercedes-Benz AMG SL 63 Features

The 2018 Mercedes-Benz AMG SL 63 Roadster is a great performance car which offers excellent equipment on board. It uses a 5.5-liter Bi-Turbo V8 and a 7-Speed Automatic gearbox to get 577 horsepower to the ground via a rear wheel.

MSRP $152,850
Key Features High-performance drive and suspension
  Active Body Control
  Upgraded brakes
  Limited-slip differential
  Unique AMG gauges and other AMG-themed aesthetic flourishes
  Dash top analog clock
  Leather upholstery
  Simulated-suede headliner

The SL 63 Roadster is available in only one trim, and that is a great trim to have. All the bells and whistles that are necessary are provided as standard to the customer, and while it is a bit pricey, the high performance of the car justifies every penny of it. Buy the optional AMG racing steering wheel if you can stretch your budget till there.

2018 Mercedes-Benz AMG SL 63 Engine

"The SL-Class has slightly synthetic handling but extremely capable. Midcorner bumps don't throw it off too badly. It's equal parts boulevardier and sports car, depending on your whims. Expect mega-power, surprising grip, powerful brakes and good manners." - Edmunds

Engine and Transmission

The 2018 Mercedes-Benz AMG SL 63 is powered by the huge 5.5-liter AMG engine that churns out 577 horsepower and earth-shattering 664 pound-feet of torque. The torque is so much that you could easily shred the tires to little pieces if you wish to.

The Engine is mated to a 7-speed twin clutch automatic, which channels all that power to the rear wheels. It is a slick and smooth system with flappy pedals behind the steering wheel for manual control while changing gear. The huge mountain of torque, along with the taller top gears, make the Mercedes a joy to cruise down the open road.

The competition to the SL 63 consists of Porsche 911 Turbo Cabriolet, Jaguar F-Type SVR Convertible, and BMW M6 Cabriolet, which make 540 hp, 575 hp, and 560 hp respectively. Although their peak power is comparable to the Mercedes, their peak torque is nowhere near close.

Acceleration

The Acceleration of the AMG powered SL 63 is nothing short of breathtaking. Put your foot on the pedal and the car greets you with rapid progress in the forward direction. 60 mph takes just 4 seconds, while the quarter mile run takes just a little under 12 seconds.

The Jaguar is half a second quicker to the 60 MPH mark than the Mercedes, while the Porsche is half a second quicker still. The BMW is more of a luxury tourer than a performance convertible, and ties with the Merc on the acceleration run. The Porsche is a little more expensive than the Mercedes too, while the others are less so.

Braking and Handling 

The Mercedes has great braking power, which it owes to the 15.4-inch front pair and a 14.2-inch rear pair of disc brakes. The curb weight of 4112 pounds does take a lot of distance to come to a halt, 102 feet to be exact. The momentum is also felt on the pedals, especially under heavy footwork.

On the handling front, the AMG SL 63 is a joy to behold. The suspension minimizes roll and the tires offer a massive amount of traction. Under heavy footwork, the car will delight you with some sideways action. Beware though, the more fun you have, the faster the tires deteriorate, and rubber on an AMG Merc is never cheap.

The BMW M6 is the heaviest in here, thus confirming that it is indeed a luxury tourer. The brakes are good, although the weight disadvantage puts it behind all the others in this comparison. The Porsche and the Jaguar are relatively lighter, and thus manage to post braking distances under 100 feet, a very impressive feat.

2018 Mercedes-Benz AMG SL 63 Fuel Economy

Until a few years ago, expecting decent fuel efficiency figures from a 5.5-liter V8 would be considered moronic. But with the advancement in technology, the Mercedes manages to give 25 mpg on the highway and 16 mpg in the city. This brings the average efficiency to 19 miles per gallon.

The tiny Porsche manages a miraculous 21 mpg overall, which defies belief by sports car standards. The Jag and the Beemer give 17 and 16 miles to a gallon respectively, which is quite decent.

2018 Mercedes-Benz AMG SL 63 Interior

"Aside from its propulsion by means of internal combustion­, the SL 63 surrenders nothing in terms of innovation and technology to anything coming out of Silicon Valley. It’s packed with nearly every feat of Magic (a registered trademark) that Stuttgart and Affalterbach can conjure." - Car and Driver

Mercedes-Benz is the leader in luxury and comfort, and it reflects in the SL 63 too. It only seats two people, which is a shame, but adequate for an expensive toy. The interiors are extremely plush and supple, and quite easy on the eyes too.

Sports cars aren't really meant for ferrying people around, which the F-type demonstrates by seating only two people. The 911 turbo and M6 seat four people, but the Porsches back seat is not comfortable for adults.

Infotainment 

The SL 63 AMG Roadster gets a Mercedes' Command infotainment system with a high resolution 11.4 cm TFT multifunction display. The stereo is a Bang & Olufsen unit, with the following:

  • AM/FM Stereo
  • CD player
  • Hard Disk Media Storage
  • MP3 Player
  • Auxiliary Audio Input
  • HD Radio and Satellite Radio

Cargo Volume

The SL 63 has a mediocre amount of space in the trunk, enough for your weekend getaway. One large suitcase, or maybe a golf bag, that is the extent of what the Merc can handle.

2018 Mercedes-Benz AMG SL 63 Exterior

"The SL 63 is not so much a car as it is a statement of what its maker’s engineers, designers, and craftspeople can produce when freed from the ordinary constraints of building a transportation tool. You can commute in it—quite comfortably, in fact—but doing so is akin to crop-dusting with an F-16 or shooting your Facebook profile pic with a Hasselblad; you’re using way more tool than the task demands." - Car and Driver

The 2018 Mercedes-Benz AMG SL 63 Roadster is a mid-size car in dimensions, but quite large in weight. It is more than 180 inches long and 80 inches wide. The ground clearance is just 3.7 inches, which is dangerously low for B-road bumps. The underbelly is way too easy to scrape on larger speed bumps.

Exterior Features 

Being a luxurious performance car, the SL 63 AMG gets a lot of features, some on the outside too. It gets:

  • Cross-spoke design wheels (19 and 20-inch rims)
  • Painted brake calipers (Black, Red, and Golden)
  • All LED lights, both headlamps, and tail lamps

2018 Mercedes-Benz AMG SL 63 Competition

Mercedes Benz AMG SL 63 Convertible vs Porsche 911 Turbo Cabriolet

Porsche is a maker of sports cars and a good one at that. Year after year, they have turned out consistently great cars, and they will continue to do so for the foreseeable future. The 911 turbo is a wonderful car if you wish to tear up the track; brag about the lap times you pulled. But the AMG can offer you just a little more.

The SL 63 is a blast to drive and will drift on every corner if you try a little. The fun factor is off the charts, and so is the desirability. I mean, who doesn’t want a Mercedes?

Mercedes Benz AMG SL 63 Convertible vs Jaguar F-Type SVR Convertible

Jaguar, now reinvigorated with Tata money, has rolled out a few new great cars recently, including the F-type. It has great power and performance, and it definitely is a pretty thing. But the ride will shatter your backbone, and that sweet V8 noise will turn annoying after a little driving.

The SL 63 is much easier on the back than the Jag, although it isn’t much easier on the pocket. But speaking of brand image, there is nothing that beats a three-point star, not even the leaping Jaguar.

Mercedes Benz AMG SL 63 Convertible vs BMW M6 Cabriolet

BMW and Mercedes have been automotive rivals for quite a long time. Both the SL 63 and M6 are great cars that offer great power for the money and are fun, luxuries, and very, very comfortable. But both have their distinct characteristics, much like everybody has a unique personality.

In between the BMW M6 Cabriolet and the Mercedes-Benz SL 63 Roadster, you would just have to decide on your own which car suits you better.

2018 Mercedes-Benz AMG SL 63 Final Verdict

The 2018 Mercedes-Benz SL 63 Roadster is a great car, especially if you are looking for a car with a split personality. The SL 63 can play the Jekyll, be the perfect urban gentleman when you need it to be, and then when the lights go out, it can play the Hyde too.

The Merc is more expensive than the competition though, so unless you have your heart set on this one, we would advise you to consider all options.
