2014 Mercedes-Benz SLS AMG GT Convertible - Rating Details


A
Edmunds Rating
Vehicle Tested 2013 Mercedes-Benz SLS AMG GT Convertible (6.2L 8-cyl. 7-speed Automated Manual) Driven On 2/12/2013 Ratings Summary This rating has been carried forward from a prior year because the newer model has no substantial differences.

With iconic, head-turning style and breathtaking performance, the 2013 Mercedes-Benz SLS AMG GT certainly qualifies as an exotic supercar. It's also just comfortable and practical enough for daily driving.
A
Performance By the numbers, the SLS is little shy of supercar acceleration, handling and braking, but the experience is otherwise exceptional. The engine itself is worthy of an A+.
Acceleration
A
Few cars offer a "race-start" program that, once accessed, launches the car perfectly, time and again. Even without it, expect 60 mph to rush by in 4 seconds.
Braking
B
Confident and powerful brakes are able to withstand repeated, heavy use without loss of performance or stability. Optional carbon-ceramic brakes are only necessary for heavy track use.
Steering
B
Friction-free and precise steering is appropriate for a grand tourer, but it lacks the tactile feel and feedback of a more dedicated sports car.
Handling
B
With its standard two-mode active suspension, this SLS's ability to grip without excess body roll is impressive. That said, as the limits approach, handling gets very edgy.
Driveability
A
Despite its performance credentials, the SLS also can be a remarkably docile traveling companion and everyday driver.
A
Comfort For an exotic sports car, the SLS is one of the most comfortable there is. Excellent seats, a multi-mode suspension and a reasonably hushed interior aren't rare, but they are nearly perfected in the SLS.
Seating Comfort
A
Standard premium-leather 12-way power-adjustable seats are heated, and the Roadster's "Air Scarf" is remarkably effective. Even tall drivers will find the SLS a comfortable car.
Ride Comfort
B
With standard two-mode active suspension, the SLS's ride comfort is either firm and controlled or track-ready. Even so, it's well suited to highway journeys.
Quietness
B
In Comfort mode, the transmission upshifts seamlessly at low engine speeds to keep the sonorous engine at bay. Even at a 70-mph cruise, our instruments showed it to be very quiet.
A
Interior The SLS's interior blends old-world craftsmanship with new-world tech in a way that few makers can. As a 2-seater, there's more room than most and its quick-operating soft top still allows for decent luggage space.
Ergonomics
A
Within the realm of 1-knob multi-controllers, M-B's version is reasonably intuitive with few mistakes. Other controls (e.g. HVAC) are very natural and logically located.
Ingress/Egress
B
Long doors (or the Coupe's long-reach gullwing doors and wide doorsills) can cause difficulty in some situations. Seating is low so miniskirts are not recommended SLS attire.
Space/Room
B
The SLS's cabin is remarkably airy. Plenty of seat travel and headroom for tall occupants; decent small storage nooks.
Visibility
B
Surprisingly slender A-pillars offer good forward visibility over the long hood. Standard parking sensors and rearview camera help tremendously.
Cargo/Storage
B
For a roadster, the SLS offers adequate cargo capacity and storage. With the top up or down, it holds 6.1 cu-ft of luggage.
Convertible Top
A
The one-touch retractable multi-layer soft-top retracts or closes in little more than 10 seconds up to 30 mph. Standard wind baffle does an excellent job keeping the interior calm.
B
Value Impeccable engineering, impressive comfort, standard equipment, and easily accessed performance are expected at this price. Mercedes-Benz heritage and classic styling rendered in a modern language are hard to put a price on.
Build Quality (vs. $)
A
Every material and surface is of high quality and each switch, knob, rocker, and hinge operate with a well-oiled and substantial action. Paint and body panels are also impeccable.
Features(vs. $)
A
With a hand-built and personally signed engine, and an impressive list of standard equipment, the SLS is expensive, but you get what you pay for.
Cost
B
About average for this elite class of vehicle.
MPG
B
The 6.2-liter V8 is thirsty, so expect to earn about 15 mpg in mixed driving like we did.
Warranty
B
With so many manufacturers offering up to 100,000-mile warranties, a 4-year 50,000-mile (with Roadside Assistance) warranty seems rather weak.
Ownership
B
Scheduled maintenance is determined by your driving habits, but is not included in the lofty price. Yet, most dealerships offer free pick-up/drop-off or loaner-car services.
A
Fun To Drive Accelerating to enter a freeway, cruising along the coast with the top down, or snaking up a mountain road, the SLS always manages to put a smile on our faces. Few cars offer this much fun in as many environments.
Driving Experience
A
Every drive has a sense of occasion and is cause for celebration. You"ll make up excuses to pull the shift paddles and lower the top just to hear the engine and feel the Air Scarf.
Personality
A
Unlike some other exotics, the SLS is sophisticated, elegant and instantly recognizable. The valet will always put it right up front, making the restaurant look classy.
