Racing car gets Lycra makeover

The bodywork uses a range of materials, including composites, aluminium, recyclable plastics and, most notably, a stretched lycra skin over an aluminium framework to create a lightweight, aerodynamically efficient and low-cost body.

Project manager Paul Faithfull commented: ’The use of materials such as fabrics has limited scope for road use, but has major benefits for racing. Imagine being able to change your bodywork in a matter of minutes, with a new body stretched over the framework, changing the colour, sponsors or just effecting rapid repairs. It is also extremely light compared to almost all alternative materials.’

The iRacer has been developed by Westfield Sportscars in conjunction with project partners Potenza Technology, Delta Motorsport, RDM Automotive and Coventry University, following funding from Regional Development Agency Advantage West Midlands.

Operational trials are currently underway in the West Midlands on a development vehicle that uses two 40kW electric YASA motors (with a peak power output equivalent to 200bhp) delivering 1,000Nm of torque. The motors are sited in place of the differential, removing the requirement for a gearbox and propshaft, and provide direct drive to each of the rear wheels.
