KWSP set out to create a modern version of the classic March 75S race car.
- Only 5 March 75S cars were ever made, aimed at competing in the European 2 Litre Sports Championship.
- KWSP set about reverse engineering the March 75S to create a modern breed of the classic race car suitable for the Sports 2000 motorsport series regulations.
- Despite being based on a historic vehicle, the full vehicle programme had to adhere to all of the technical requirements of modern motorsport series, including:
- Safety regulations
- 2 Litre engine restrictions
- Competitive pressures of a modern series
- KWSP firstly reverse engineered the 09R from the bodywork of the original March 75S.
- CAD data was then transferred in to CFD software to optimise the aerodynamic shape.
- The monocoque was then constructed in aerospace aluminium incorporating a safety cell, front impact crash box and roll over structure.
- The entire design was validated using computer simulation and FEA.
- Down force to drag ratio was increased from 1 to 4.5.
- The 09R was immediately competitive, taking numerous podiums in its first season.
- Following further development, the 09R shone at the Brands Hatch GP enduro, taking the lead early and leading almost every lap before taking victory.
