The Mercedes-Benz SL-Class has long been synonymous with luxury, performance, and timeless design, and the SL 600 variant within the R230 chassis exemplifies the pinnacle of these qualities.

Introduced as part of the fifth generation of the SL-Class, the R230 chassis, the SL 600 combines sophisticated engineering with opulent features to create a driving experience that remains unparalleled. With a V12 engine under the hood, the SL 600 delivers an impressive blend of power and refinement.

The R230 chassis, produced between 2003 and 2011, has earned its place as a modern classic, and is becoming coveted by enthusiasts and collectors alike. For those who are lucky enough to own a SL, or considering ownership, RENNtech’s comprehensive catalogue of performance and handling upgrades provides improvements to the SL, ensuring owners can enjoy the Mercedes-Benz roadster for many years to come.

February 24 AMG G63 R1

Loaded with motorsport derived solutions, the 2021 AMG GT Black Series is arguably the most track focused road vehicle from Mercedes-Benz AMG since the (homologated) street version of the CLK GTR in 1998.

On the power side,RENNtech’s Hand Held ECU Tuner  instantly produces an additional 99 HP and 95 LB-FT, bumping the AMG GT Black Series up to 843 HP and 739 LB-FT.  If that is not enough, the R3 -upgrade delivers an mind-blowing 1066 HP and 831 LB FT running on 93 octane pump gas, making the AMG GT Black Series RENNtech R3 the most powerful Black Series in the world. 

At the heart of the R3 -upgrade is a set of larger and more capable Turbo’s, a set Stainless Steel Downpipes, Blow Off Valves, and BMC Airfilters for improved exhaust sound and flow. To control the power increase, RENNtech has developed a TCU- tune (Transmission Control Unit) for faster and more firm shifts while increasing the torque capacity of the Mercedes-AMG 7-speed dual clutch transmission. The addition of the Stainless Steel Downpipes and Electronic Valve Module (EVM) improves the sound of the M178 V8, and fills the cabin with a raw and unrestricted sound punctuated with the occasional down-shift crackle. 

In late January we received a call from a customer who acquired a low mile AMG GT63S Edition One. The customer wanted to know about our GT63 (S) and M177 Engine development, and if it was possible to turn his Edition One into a 9 Second ¼ mile car. This had to be achieved without removing any seats or adding nitrous, and the car needed to run on factory Michelin Pilot Sport 4S street tires, and 93 Octane fuel for daily comfort.
