If you were Mercedes-Benz, and you wanted to breathe a few more years of life into the range-topping SLS AMG, how would you do it? You wouldn’t alter the design much, because the car’s retro-futuristic lines pay homage to the iconic 300 SL Gullwing, while delivering a presence that few other cars on the planet can match. You’d be hard pressed to up the content level, since the SLS AMG (in coupe or roadster form) already delivers just about any amenity you could ask for.
If you guessed “up the performance,” you’d be correct. For 2013, the SLS AMG adds “GT” to its name, gets an additional 12 horsepower and receives a revised seven-speed dual-clutch gearbox, which makes perhaps the biggest contribution to its added capabilities. There’s a new AMG Adaptive Performance Suspension, complete with electronically-adjustable dampers, as well as a few tweaks to the car’s styling.
Thankfully, these changes are minor and tasteful....
