Donkervoort D8

Donkervoort D8 is a series of ultra-light weight sports cars manufactured by Dutch car manufacturer Donkervoort in Lelystad, Netherlands since 1993. They have been produced in several variants, starting with the original Donkervoort D8 Zetec (1993-1998), which used engines made by Ford; since 1999 the cars have used engines built by German automobile manufacturer Audi.

Ford engines (1993–1998)
The Donkervoort D8 Zetec Classic replaced the Donkervoort S8AT in 1993; while the S8AT used a turbocharged OHC 2.0L Ford engine, the D8 Zetec used the recently-introduced Ford Zetec engine (1.8L and 2.0L Zeta engines). In 1994, the Zetec Sport was introduced, with weight reduced by swapping some metal body parts for carbon fibre, downsizing the battery, and replacing the cast iron clutch housing with an aluminum equivalent. Externally, the Classic can be distinguished by the traditional long front fenders which extend from the front wheel to the forward edge of the doors, while the Sport is equipped with cycle fenders covering just the front wheels.

The Donkervoort D8 Cosworth was introduced in 1995, available in both Classic and Sport models. The turbocharged Cosworth YB engine, better known as the powerplant for the Ford Sierra and Escort RS Cosworth homologation specials, had an output of either 220 or, resulting in a top speed of 235 km/h and acceleration from 0 – of 4.1 to 4.8 seconds. The Cosworth can be distinguished from the Zetec by the number and arrangement of vents in the bonnet.

Audi engines (1999–2012)
Donkervoort D8 Audi (1999-2003) and D8 (E-gas) Wide Track (2004-2012) followed the Zetec-engined cars. The first Audi model used the 1.8T 20V Audi R4 engine (AGU), with a choice of outputs initially selectable from 150 or; in 2003, the Wide Track model was made available with an electronic throttle ("E-gas") version of the same Audi engine. The D8 Sport received an uprated 155 kW version of Audi's turbocharged 1.8-liter engine that year. These were made available as Touring, Sport, and Race models and sometimes carried the nominal output as a designator, for example, the D8 150 was the original Audi (AGU) engine with 150 hp output, while the D8 e210 had the E-gas engine with 210 hp.

The chassis of the Audi models was new, using lessons learned from the D20 project. Styling of the D8 with Audi engines followed that of the D8 Cosworth Sport, with minor changes to distinguish the former until the Wide Track model received a new nose and front light arrangement along with a wider stance.

In 2004, the Wide Track-based Donkervoort D8 RS broke the lap record for street-legal cars at the Nürburgring Nordschleife by 15 seconds; a limited series of 25 D8 270 RS cars were built with an output of 270 hp and made available to celebrate the lap record; the D8 270 subsequently was placed into regular production in 2008. The D8 270 was the seventh fastest production car on the Nordschleife in 2011, with a lap time of 7:14.9. The 270 can be distinguished from lower-powered models by the shape of the nose and front grille, which was revised to accommodate a larger cooler and extra radiator on the side.

The first Donkervoort hardtop, the D8 GT, was introduced in 2007 at the Geneva Motor Show. It features butterfly doors for access and a revised headlamp housing; the track was widened by 8 and 4 cm in the front and rear, respectively; overall length increased by 30 cm with no change in wheelbase. Weight increase over the regular D8 cabriolet is minimized by extensive use of carbon fibre in the roof, rear end, doors, and fenders. A similar selection of engine outputs of 180, was available. Production of GT models was limited to 50 examples per year starting from 2008.

GTO (2013–2022)
Donkervoort announced the next-generation D8 GTO in December 2011, which was larger and slightly heavier than earlier D8 models. All GTOs are powered by the five-cylinder 2.5T 20v Audi R5 engine.

The D8 GTO models include the Donkervoort D8 GTO (2013-2021), D8 GTO Premium (2013), D8 GTO Bilster Berg Edition (2014-2015) and the D8 GTO RS (2016-2021). In 2015 the all-carbon fiber GTO Bare Naked Carbon (BNCE) appeared. In 2019 a special edition, Donkervoort D8 GTO-JD70, was created, followed by the Donkervoort D8 GTO-JD70 R the next year, in honor of founder Joop Donkervoort's 70th birthday.

Donkervoort released the Donkervoort D8 GTO Individual Series in September 2021 which offers the ability to customize the vehicle to the client's exact specifications. Donkervoort claims that the only limit is what's legal in the European Union. It also marks the end of D8 production. The starting price is €162,900 but the final price depends on the customizations chosen. Donkervoort released the Donkervoort D8 GTO Individual Series in the US in July 2022; it was the first Donkervoort officially released in the US with a starting price of US$240,000 and the first example was delivered to a buyer in Florida. Two others were shipped to clients in California and Colorado.
