First Look: 2013 Mercedes-Benz SLS AMG GT
Mercedes-Benz has upped the ante on its SLS AMG super car for 2013. The gull-winged brute has seen its power output bumped to 583 Teutonic stallions (up from 563 horsepower in 2012). Torque remains the same at 479 pound-feet. Internal tweaks to the combustion pressure, among other things, are responsible for the power increases from the 6.3-liter V-8.
The newly enhanced SLS can now sprint to 60 miles per hour in a manufacturer-estimated 3.6 seconds (a tenth faster than the 2012 model), before topping out at an electronically limited top speed of 197 miles per hour (at which point electronic limiting seems a bit superfluous).
Other tweaks to the seven-speed AMG Speedshift dual-clutch transmissions should help with that sprint to 60, thanks to the tranny’s improved reaction times and recalibration.
The biggest piece of news is the new AMG Adaptive Performance Suspension. In the default Sport mode, the SLS AMG GT features a stiffer spring/damper arrangement compared to last year’s model. Sport Plus increases the stiffness further, thanks to the electronically controlled dampers.
Finally, an AMG designo Style offers three distinct color packages in single and bi-tone arrangements. Buyers will get exclusive designo leather and contrast stitching in a diamond pattern. A fair majority of the interior is also finished in leather, while the roof (in the hardtop) and roll hoops (in the roadster) are lined with Alcantara suede.
Pricing has not been released as of this writing, but we’d suspect that the 2013 models will see a slight price increase over the 2012s ($189,875 for the coupe, and $196,975 for the roadster). The SLS AMG GT goes on sale in November of 2012.

The New SLS AMG GT
June 05, 2012
The new 2013 Mercedes-Benz SLS AMG GT boasts enhanced driving dynamics and even better on-track performance. With an enhanced maximum output of 583 hp (435 kW), a re-calibrated AMG SPEEDSHIFT DCT 7-speed sports transmission and the redeveloped AMG Adaptive Suspension, the new SLS AMG GT – which is available both as a Coupé and a Roadster – has raised the bar even higher. As a further highlight, a new optional AMG designo STYLE interior package is now also available for the 2013 SLS AMG GT. According to Tobias Moers, Board Member and Head of Overall Vehicle Development for Mercedes-AMG GmbH: "The new SLS AMG GT demonstrates the sort of potential which lies in AMG’s super sports cars. With its even higher levels of performance, the SLS AMG GT excites out on the race track in particular by providing an emotionally enjoyable and passionate driving experience."
For MY2013 in the U.S., Mercedes-Benz will now exclusively offer the new SLS AMG GT. Available as a Coupe and Roadster, it will go on sale in mid-November 2012, replacing previous SLS AMG versions.
Masculine and decidedly athletic the new SLS AMG GT is distinguished by darkened headlamp and tail light lenses a unique wheel color and red-painted brake calipers. The wing-shaped cross fins and the star recess in the radiator grille are given a new high-gloss black finish, as do the exterior mirrors and the fins on the hood and front fenders. The AMG logo on the right of the trunk lid also features the additional letters "GT" to clearly identify this new model.
One look at the technical specifications highlights the fact that AMG successfully elevated the dynamic profile of the SLS AMG GT even further. The maximum output of the AMG 6.3-liter V8 front mid-engine has been increased to 583 hp at 6800 rpm, while the maximum torque is maintained at 479 lb/ft at 4750 rpm. These changes yield a 0-60 mph acceleration time of 3.6 (est) seconds with a max speed of 197mph (electronically limted)

Mercedes-AMG has achieved the output of 583 hp through internal dethrottling measures in conjunction with an increase in peak combustion pressure. The SLS AMG GT M159 6.3-liter eight-cylinder engine responds with even greater agility to accelerator pedal movements and excites with even sportier-tuned performance characteristics. The AMG SPEEDSHIFT DCT 7-speed sports transmission located on the rear axle is more direct and aggressive in the manual "M" transmission mode. Thanks to newly developed gear change logic and optimised transmission control, it has been possible to shorten reaction time significantly during shifts.
When changing gears manually via the alloy shift paddles on the AMG Performance steering wheel, gear change are executed crisply and markedly quicker than previously – all of which is ideal when striving to achieve ambitious lap times on a closed race circuit.
These changes in shift reaction time and feel provide an even more emotional experience for the driver. The automatic double-declutching function when downshifting is also more pronounced in the SLS AMG GT. Due to a modified engine mapping profile that changes the engine torque delivered in manual mode, the shift procedure is even quicker than previously – and is accompanied by some passionate acoustic feedback for the driver. Overall, the optimization of the dual clutch transmission complements the sportier focus of the SLS AMG GT perfectly.
New AMG Adaptive Performance Suspension
It is not just the enhancements to AMG’s M159 6.3-liter V8 and the optimized dual clutch transmission which are responsible for increasing the driving dynamics of the SLS AMG GT. The newly developed AMG Adaptive Performance Suspension also enhances the vehicle’s sportiness. In the case of the SLS AMG GT, Mercedes-AMG has combined the sophisticated suspension layout of twin aluminium wishbones all round with specially tuned variable, electronically controlled dampers. Compared with the AMG Adaptive Suspension from the 2012 Model Year SLS AMG, the new AMG Adapative Performance Suspension for the SLS AMG GT features stiffer and more aggressive spring/damper tuning for a more dynamic feel.
"Sport" mode is tuned as the optimum setting for undulating road surfaces and routes requiring increased suspension travel – such as found on rural roads or the legendary North Loop of the Nürburgring, for example.
The control algorithm of the AMG Adaptive Performance Suspension reacts best to fluctuations in the road surface with a tendency towards lower/softer damper force levels. The resulting effect is the best possible performance by effectively preventing body roll for enhanced contact with the road when adopting a sporty driving style. The enhanced driving dynamics and even better race track performance are measureable: as part of an internal comparison with the SLS AMG, the SLS AMG GT is able to achieve faster lap times on a race track.
"Sport plus" provides higher/firmer damping forces and features specific control algorithms which have been adjusted for a decidedly sporty driving style on routes with a level road surface – such as when trying to achieve ambitious lap times on a race circuit such as Hockenheim.
Selection of suspension modes via the AMG DRIVE UNIT
Depending on the driving conditions, speed and vehicle load, the AMG Adaptive Performance Suspension adjusts the damping characteristics at lightning speed and automatically reduces the roll angle of the body. The two modes can be selected via a button on the AMG DRIVE UNIT. The activated suspension mode is indicated by means of indicator lamps on the button and the display in the AMG main menu.
As standard, the vehicle comes with 265/35 R 19 tires on the front and 295/30 R 20 tires on the rear, fitted to weight-optimized AMG forged light-alloy wheels featuring a 10-spoke design and that are inlayed in a matte black finish and with machine polished high-sheen finish on the face of the wheel. Three additional optional AMG light-alloy wheel styles/colors are also available.
Interior with consistently sporty highlights
The interior of the SLS AMG GT features a distinctivly sporty design: combining the high-quality, exclusive ambience of a true AMG model with the emotional atmosphere of a racing car. The sports seats covered in designo leather, feature center sections finished in Alcantara® and are accented with an embossed AMG crest on the head restraint. Complimenting the styling design of the seats, Alcantara® is also found as an accent on the door panels. These premium materials are combined with red seat belts, red trimmed floormats and red contrast stitching thoughout the interior on the sports seats, center console, dashboard, and door panels.
The high-gloss black trim on the center console and door panels perfectly match the new high-gloss black finish found on the trim rings of the air vents and the real metal insert on the AMG Performance steering wheel. The steering wheel has been enhanced as well with side grips finished in Alcantara®, a flat bottom section and now features a new red 12 o’clock marking for easier orientation while driving. The instrument cluster of the SLS GT has also been visually enhanced with new black dials and a black accent surrounding the LED shift lights.
AMG designo STYLE interior package for all SLS AMG GT
Also now available with the introduction of the SLS AMG GT, is a new, highly exclusive option in the form of the AMG designo STYLE package. This expressive option is available in three different color combinations in both single and two-tone finishes. It comprises a distinctive upholstery design featuring full designo leather with a contrast stitching and a diamond quilt design on the seats and door panel inserts.
Other highlights include designo leather for the entire dashboard, the beltlines, door armrests and the handrest on the centre console. AMG floor mats are in black with porcelain leather edging and the roof lining and parcel shelf (Coupé) or roll-over bar (Roadster) are finished in porcelain Alcantara.® Seat piping is also finished in contrasting colors which offer an exciting highlight and underscores the exclusive, hand-finished nature of this new styling package. Available color combinations include mocha brown/porcelain, titanium grey/porcelain and mystic red/porcelain.
