Team Profile
Warwick Racing is a team of 15 fourth-year undergraduate students specialising in either a Mechanical or Automotive Engineering MEng degree. Their latest Formula Student car, WR4, has been designed and manufactured with innovation and light-weighting in mind. The overall project and team is managed by the Project Manager; the Chief Engineer is responsible for delivering the technical aspects. Chassis and Powertrain sub-team leaders, and the Sponsorship and Finance Manager, offer additional managerial support.
WR4 is the fourth petrol engined single-seat race car built by Warwick Racing, and the most promising iteration to date.
The powertrain team have sourced a number of new components, most notably the KTM single-cylinder engine and Drexler LSD. This has seen a switch to a new hand-clutch and shifter system for greater drive-ability, but, perhaps the most exciting part from the powertrain team is the final drive anti-shock sprocket system.
To house this new powertrain set-up, the chassis team have produced
a steel tubular spaceframe complete with optimised removable aluminium bulkhead to aid accessibility. CFRP and sandwich composites have been used extensively to minimise weight without compromising on performance, most notably in the new impact attenuator design.
