What better way to mark a 35th Anniversary than by achieving a remarkable milestone? RENNtech, the renowned #mercedesbenz #amg #cartuning
specialist, has once again pushed the boundaries of automotive performance by establishing a new record. In early January. Their meticulously crafted RENNtech-built AMG GT63 Edition 1 achieved an astonishing quarter-mile time of 9.78 seconds, firmly securing its position as the fastest Mercedes-AMG GT63 on the quarter-mile strip.
This exceptional achievement eclipses the previous record of 9.99 seconds, which had been held by the same vehicle since June of 2023. The quarter-mile sprint is a fiercely competitive arena where every fraction of a second matters, and RENNtech’s latest triumph underscores their relentless pursuit of automotive excellence.
Owner of the record-setting vehicle commented, “I did not resort to any unconventional methods to enhance performance. The car remains street-legal and can seamlessly transition from the garage to everyday cruising without any modifications. That’s the driving experience I envisioned for this car.”
The Dragy measured results reveal a momentary deceleration around the 1100-foot mark, reminiscent of Usain Bolt’s effortless glide to victory at the 2008 Beijing Olympics. When asked about this, the owner remarked, “I simply chose not to push the car to its limits.”
In addition to its quarter-mile prowess, the AMG GT63 Edition 1 showcased its remarkable power with a staggering 60-130 mph time of 4.92 seconds during a follow up run. Equipped with lightweight magnesium wheels and high-performance Nitto 555 R2 tires, this four-door powerhouse outperforms exotics like the LaFerrari and competes neck-and-neck with the Ferrari SF90 on the rolling 60-130 mph sprint.
So, how did RENNtech achieve this feat? Through meticulous engineering, relentless dedication, and considerable investment of time and resources. For over three decades, RENNtech has been at the forefront of developing performance-enhancing components that elevate Mercedes-Benz AMG vehicles’ capabilities without compromising their quality or reliability.
The RENNtech parts list for the AMG GT63 S Edition 1 includes larger turbochargers, advanced ECU tuning, carbon fibre air intakes, high-flow downpipes with 200-cell catalytic converters, lightweight sport mufflers, upgraded high-pressure fuel system, and enhancements to the transmission (TCU) and drivetrain (CPC). By using 100-octane fuel, drivers can unleash over 1000 horsepower or slightly less, with 93-octane fuel.
With RENNtech’s expertise and performance upgrades, owners of AMG GT63 (X290) and other Mercedes-Benz AMG, Aston Martin, Porsche, and European performance cars can elevate their driving experience to new heights.
