The Westfield iRacer pictured here represents 99% of the production model, say its exhibitors at the Geneva Motor Show.
When discussing the concept with friends recently…the query was raised as to whether the cars would have massive sound systems emitting the sound of high-revving petrol engines to deliver the full atmosphere of motor racing. IMHO, though, it will just add a new dynamic – dramatic racing amidst more resonant sounds of nature and social intercourse? Think of it more as a sailing race – only on a track and with more speed?
The car was designed by Elliott Hawkins, a graduate from the Royal College of Arts vehicle design course. A number of materials were used for body construction, including aluminium and recyclable plastics and the iRacer has the pulse of electric power running through its veins.
Whilst the use of materials such as fabrics has limited scope for road use, they do have major benefits for racing. You can 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 concept weighs 600kg (1,323 lbs), is 3.6 metres long and is rear-wheel-driven. Its Lithium Phosphate battery helps the motor make 80kW (109 PS) and 1,000Nm at the wheels. The 0 – 60mph sprint is said to take under 5 seconds and top speed is limited to 177km/h. Westfield reckons a race range of between 80km and 97km (50 and 60 miles) is possible.
The iRacer will make its racing debut at the EV Cup one-make race car series launching in 2011.
