    Its not everyday when news of an automaker refreshing their supercar comes out, but that is what Mercedes-Benz is doing. Today, the company announced the 2013 SLS AMG GT. The GT is to make note of the light refresh when it goes on sale in November.

    Starting under the hood, the SLS AMG GT naturally-aspirated 6.2L V8 sees its output climb from 563 HP to 583 HP. Torque remains at 479 lb-ft. Mercedes claims a 0-60 run of 3.6 seconds and a top speed of 197 MPH (electronically limited).

    Mercedes also recalibrated the 7-speed dual-clutch transmission for quicker and more direct shifts in manual mode. The SLS AMG GT's suspension is stiffer thanks to recalibrated springs and dampers.

    Inside, the SLS AMG GT gets piano black accenting on the center console and doors, red seat belts and red-trimmed floormats, and a custom AMG Performance steering wheel with Alcantara grips.

    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)

    The key data at a glance: Mercedes-Benz SLS AMG GTCylinder arrangement V8 Valves per cylinder 4 Displacement 6208 cc Bore x stroke 102.2 x 94.6 mm Compression ratio 11.3:1 Output 583 hp at 6800 rpm Max. torque 479 lb/ft at 4750 rpm Fuel economy 14 city / 20 highway / 15 combined Acceleration 0-60mph 3.6s (est) Top speed 197mph*

    Please note, preliminary figures.

    * electronically limited

    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.

    Other attractive optional extras for the SLS AMG GT include (extract):

    • AMG carbon-fiber exterior mirrors
    • AMG carbon-fiber engine compartment covers
    • AMG Interior Carbon-Fiber package (carbon-fiber trim, trim on seat backrest and side, door sill panels)
    • AMG carbon ceramic high-performance composite braking system
    • AMG Performance Media
    • AMG 10-spoke forged wheels in additional colors
    • AMG carbon-fiber interior trim
    • Bang & Olufsen BeoSound AMG surround sound system

    The specific assembly area for the SLS AMG is located in the largest Mercedes-Benz production plant in Sindelfingen. The AMG 6.3-liter V8 engine comes directly from the AMG engine workshop in Affalterbach, where it is hand-assembled according to the traditional "one man, one engine" philosophy.

    40 significant awards for the Mercedes-Benz SLS AMG

    The SLS AMG has succeeded in winning numerous comparison tests against a host of international competitors conducted by the international specialist media – both as the gullwing model and the Roadster. Since its world premiere at the IAA International Motor Show in Frankfurt in 2009 and the presentation of the SLS AMG Roadster in May 2011, the super sports car from Mercedes-AMG has picked up a total of 40 awards – including such major prizes as the "German Design Award", the "Red Dot Design Award", the "Golden Steering Wheel 2009", "Classic of the Future", "Sports Car of the Year", "Best Performance Car" and "Legends on Wheels".

    Freakin HOT HOT HOT!!! :explode:

    I have to say that I do dig this new model both the gullwing door version and the convertible. I wish Caddy still had their XLR as it was a great halo car even though it was a slow seller. I cannot imagen it was costing them that much to poach the main parts from the corvette.

    Should have just had it as a XLR-V edition only. It would have still sold. :banghead:

    I love this car, it looks good from every angle. The 1954 is still the best, but this is a close second. I wish they left GT off the name, it has enough letters already.

    "SL-SAM-GUHT" ??

    Why, if it's a 6.2L, does mercedees bill it as a 6.3??

    They should've made the A/C vents 3-pointed thingies and then could've had 5 MB emblems across the dash. :P

    Don't like the design- too busy & cluttered.

    I agree with the AC vents, would have been a good idea. Someone was asleep at the interiors decorating meetings. :D

    Yea the dash is busy, but it does make a statement of look at me. It is rememberal compared to so many other bland blah dashes.

    In this regards, when you have an ubber exclusive car like this, you want it to stick out in the minds of others and I think they have done that except for the oversight on the AC vents.
