Cardiff Racing is a team of multi-disciplined Engineering students from first year undergraduates through to post graduates. This year's entry, CR07, has been designed mainly by fourth year design students, while the volunteers carry out manufacturing, marketing and dynamic testing.
CR07 builds upon the experience gained by the team in previous years. The chassis is a complete monocoque, constructed from lightweight, high stiffness aluminium honeycomb composite panels. The sidepods house cooling and electrical systems allowing space at the rear for more efficient packaging and easier engine maintenance.
Power is provided by an Aprilia SXV 550 V-Twin engine with optimised intake and exhaust systems. The engine uses a custom ignition and fuel map developed in-house using the Cardiff University engine dynamometer. Power is transmitted through a student designed aluminium spool that has resulted in faster lap times in testing than a differential.
The suspension system is the lightest yet from Cardiff Racing, utilising Fox Van RC dampers. Significant testing was carried out using last year's entry, CR06, in order to develop driver controls which were simplified to improve gear changes, and refine the adjustable launch/traction control which makes the car suitable for drivers of varying experience.
