The online critics and competing automakers can cease their doubts and speculations regarding whether the Ford Mustang GTD Competition has achieved the impossible on street-legal tires.
The Drive has verified that the Ford Mustang GTD Competition, which shattered the Chevrolet Corvette ZR1X’s Nurburgring lap record, was indeed equipped with street-legal tires. These tires are Michelin Pilot Sport Cup FR, not slicks.
Ford brought the record-setting vehicle to Laguna Seca Raceway during Monterey Car Week on the very tires used to establish a ‘Ring time. There are even melted sections visible on the tire’s outer edge displaying feathering.
The FR in the Michelin Pilot Sport Cup tire designation stands for “Felgenrippe,” which translates from German to “rim rub” or “flange rib.” This refers to the integrated rim guard, a rubber ridge on the lower sidewall designed to protect wheels from curb damage.
In April, Ford announced that the Mustang GTD Competition had completed a lap at the Nurburgring in a remarkable 6:40.835. This is one of the fastest times for any street-legal car currently available, surpassed only by the Mercedes-Benz AMG One hypercar, which utilizes a Formula 1 powertrain.
Ford has remained tight-lipped about the enhancements the GTD Competition holds over the standard GTD, which is priced at over $325,000. However, it is known to produce more than the standard model’s 815 horsepower due to both upgraded components and tuning. Ford has also acknowledged modifications to the rear wing using the DRS system and the addition of dive planes on the front bumper. The carbon fiber aero discs on the rear wheels are quite noticeable. Those wheels are now made from magnesium, and carbon fiber bucket seats are another weight-saving measure. There are lighter dampers, though the exact implications of that remain uncertain. Ford also admitted to “additional actions to help minimize weight,” though specific details about those measures are not disclosed.
In 2024, the Ford Mustang GTD achieved the title of the fastest American car to lap the Nurburgring. Then, in May 2025, Team Ford reset and improved its own record by an astonishing 5.5 seconds.
However, Team Chevy soon exceeded the Blue Oval’s Nurburgring record, not once but twice, just two months later. Ford CEO Jim Farley took it as a personal challenge and stated, “Game on.”
Months later, The Drive observed a modified Mustang GTD aggressively lapping the ‘Ring, possibly to set a new record or test modifications. However, a record was not achieved since Ford returned to the ‘Ring in March to commence hot laps once more with a prototype. Ultimately, the modified and enhanced GTD shattered the Corvette’s records—and not by a small margin.
Incredibly, the GTD Competition trimmed an astounding 11.237 seconds off the GTD’s lap time. This remarkable discrepancy had rival manufacturers and online critics questioning whether the Mustang GTD Competition was indeed using street-legal tires. It was.
