Mercedes-AMG GT R’s tuner Renntech says there’s more potential in the car for even lower Nurburgring lap times.

Mercedes-Benz is known worldwide for its wild fire-breathing AMGs. What happens when aftermarket tuner RennTech gets their hands on a SL55?

The SLR McLaren still holds a special place in the hearts of MB fans, especially when its tires are blazing.

OEMs have been battling for years to see who can accelerate fastest, but for this one, we get a peek at two renowned tuners: Evotech and Renntech.

This RENNtech-tuned Mercedes-Benz CL65 AMG is so powerful, it ran a quarter mile in 10.62 seconds at 133.7 mph. But we’re not here to watch it skip across the track.

If you don’t think the already-mean SLS AMG Black Series is quite hardcore enough, RENNtech can help you out with that.

If you’re looking to turn up the horsepower and volume of your Mercedes-Benz SUV, look no further than Renntech’s line of performance add-ons.
