- Driven: 2014 Mercedes-Benz CLA45 AMG
- Mercedes – Benz Announce New 2015 C-Class
- 2013 Mercedes-Benz GLK350
Starting this fall, the gull-winged SLS AMG coupe and its non-winged roadster counterpart will officially become the SLS AMG GT. Along with the new suffix comes a host of hardware upgrades for the 2013 model year.
By reducing internal flow restrictions and dialing up combustion pressure on the naturally aspirated 6.2-liter V8 (which Mercedes generously rounds its 6208 cc all the way up to 6.3 liters for marketing purposes), the hand-built AMG engine now musters 583 horsepower at 6800 rpm, up 12 horses from the previous figure. Peak torque remains the same at 479 lb-ft at 4750 revs. Power still feeds the rear wheels through the seven-speed AMG Speedshift dual-clutch gearbox, though shifting times have been shortened for a more engaging driving experience as well as a new 0-to-60-mph time of just 3.6 seconds.
The adaptive sport suspension has been sharpened as well, with a refined algorithm for better body control on a variety of road surfaces, resulting in faster lap times should you take your new GT to the track.
In addition to the drivetrain and suspension tweaks, the interior now receives M-B’s “designo” design elements in the cockpit, including upgraded leather and Alcantara on the seats and door panels. New black gauge faces compliment the piano black center console and door trims for the full effect.
The updated SLS AMG coupe and roadster will be available from November of 2012 as the 2013 Mercedes-Benz SLS AMG GT. Pricing will be announced closer to availability.
