Grand Prix Masters

Grand Prix Masters was a one-make motor racing series featuring retired Formula One drivers. The inaugural (and sole 2005) event, at the Kyalami Grand Prix Circuit in South Africa, took place on 11–13 November, but the series folded after a two-race season in 2006.

Concept
Grand Prix Masters was modeled on the lucrative seniors tours of golf and tennis. In order to compete, drivers must:


 * Have retired from all forms of open wheel racing
 * Have competed in (and retired from) F1 for two complete seasons
 * Have passed a medical examination
 * Be more than 45 years (later 40 in 2006) on 1 January for the season to follow

Car
All participants raced identical open wheel cars, which are based on the 2000 Reynard 2KI. The chassis was built by English constructor Delta Motorsport, and was powered by a naturally aspirated, 3.5-litre, 80-degree V8 engine produced by Nicholson McLaren. The engine was based on the Cosworth XB engines previously used in Indy car racing, and according to the series' organisers, it produced more than 650 bhp at 10,400 rpm with over 320 lbft torque at 7,800 rpm.

In 2007 cars were to have been powered by a Mecachrome 90-degree V8 4.0 litre. It developed 600 bhp and revved to in excess of 9500 rpm.

Gearbox operation was controlled by a contemporary paddle shift arrangement.

Grand Prix Masters promoters boasted that the 650 kg (1433 lb.) cars reach 200 mi/h. Claiming that the combination of stable aerodynamics and considerably simpler technology (than in use in modern Formula One) better demonstrate driver skill and promoted overtaking, electronic "drivers' aids" (such as traction control, power steering and ABS) were absent, and brakes were made of steel rather than carbon (as in many contemporary single seater race cars) to increase braking distances.

On track
The Grand Prix Masters car first ran in late-September 2005 in the hands of Delta Motorsport Operations Director Simon Dowson. He reported a successful shakedown, despite appearing to sit very high in the car, his helmet appearing to sit level with the top of the roll-over hoop.

In mid-October 2005, Nigel Mansell and René Arnoux tested the car at the Pembrey Circuit in South Wales. 26 October saw the first multi-car test for the series, with Mansell, Andrea de Cesaris, Stefan Johansson, Derek Warwick, Alex Caffi, Hans-Joachim Stuck, Patrick Tambay and Christian Danner running at the Silverstone Circuit in England. De Cesaris was fastest, Danner slowest whilst Tambay crashed.

Controversy
There were questions surrounding the fitness of the former Formula One stars who ended up competing in the series. Participant Christian Danner questioned the ability of 1980 World Champion Alan Jones and former GP winner Patrick Tambay in particular, given the rapid expansion of these drivers' waistlines since retiring from racing. Jones hit back claiming the only time Danner had seen a Grand Prix podium was when he passed it on the way to the lavatory. Jones' lack of fitness at the first GP Masters event might suggest Danner's assessment had some merit.

2005
The first event, and the only event of the 2005 season, took place at Kyalami in South Africa on 13 November 2005. Nigel Mansell took pole then won after battling hard with Emerson Fittipaldi. Riccardo Patrese was third. Andrea de Cesaris finished fourth after a storming drive, where he pushed past Derek Warwick. Stefan Johansson spun out early on. Jacques Laffite retired with damaged right-front suspension after colliding with René Arnoux. As predicted, Alan Jones proved a disappointment. In practice he was up to ten seconds off the pace of Mansell, before pulling out of the race –- ostensibly due to neck injury. He was replaced by Eliseo Salazar.

Bankruptcy
On 18 September 2007, Delta Motorsport, supplier of the GP Masters chassis, announced they were filing a petition with the British High Court to have the GP Masters Operating company placed in liquidation due to non-payment of invoices. Following a hearing on 28 November 2007, the Grand Prix Masters series was officially wound up.

In the first quarter of 2008 Delta Motorsport stated that they intend to re-launch the series under the name F1 Masters using the original car that they manufactured for the GP Masters series.
