After just a couple of years on the market, Mercedes-Benz is readying the subtlest of facelifts for the SLS AMG GT Roadster. The front fascia appears to be the main focus of attention where a new bumper and restyled grille will be added. When Mercedes unveiled the SLS AMG GT coupe, it not only added the "GT" to its refreshed supercar but also bumped output to 583 hp, retuned the AMG Adaptive Performance Suspension and sharpened the seven-speed dual-clutch box. The Roadster variant has already received these upgrades, so this facelift will almost certainly be purely cosmetic.
