Back in June, Dutch sports carmaker Donkervoort celebrated the 70th birthday of the company's founder, with the bonkers Donkervoort D8 GTO-JD70. Based on the D8 GTO track car and limited to just 70 examples, the JD70 edition is extremely lightweight thanks to the extensive use of carbon fiber, making it thrilling to drive. But there's now an even more hardcore version. Say hello to the JD70's new track-only sibling: the Donkervoort D8 GTO-JD70 R. Designed to smash track records and win races, Donkervoort describes the new R version as the "fastest, most attacking, least compromised Donkervoort ever engineered."

Like the standard JD70, the track-only roadster sports car is powered by a 2.5-liter five-cylinder engine sourced from an Audi TT RS producing 415 horsepower and 383 lb-ft of torque. Donkervoort doesn't provide any performance specifications, but the JD70 R weighs only 1,576 pounds so it should be capable of setting some seriously fast lap times. A custom set of slick racing tires also improve the car's grip, and Donkervoort also offers lightweight carbon-fiber rims.

One of the biggest changes is the addition of a Bosch M5 Clubsport anti-lock braking system, which is more aggressive than the standard JD70 road car and provides a "massive advantage in driving consistency." To improve the JD70 R's cornering ability, Donkervoort added an adjustable racing power-steering system.

While the JD70 R is still offered with a traditional steering setup, Donkervoort claims the car is "faster and easier to correct" with an electronic power-steering system. The dampers, springs and anti-roll bars are 20 percent stiffer and the JD70 R rides 0.7 inches lower to the ground than its road-going sibling. There are also "major changes" to the gearbox.

Thanks to these modifications, Donkervoort claims the JD70 R will lap the Spa-Francorchamps five seconds faster than the standard JD70 and three seconds faster than the 1,100-hp Koenigsegg Regera. Whereas the Regera will cost you $2 million, pricing for the JD70 R starts at €198,000 ($234,225) before tax.
