Battery-compelled vehicles are moving into motor racing and the sport’s national governing body is now working out how to accommodate them.

THE public unveiling of Hayden Paddon’s highly-anticipated Hyundai Kona electric rally car tomorrow is being accompanied by a review of MotorSport NZ regulations to encourage electric vehicles in competition.

Motorsport’s national body says it is supportive of including EVs in competition and 18 months ago it established a Working Group to produce guidelines for their inclusion. The regulations are now at a final draft stage.

 ``The draft guidelines were to be released a couple of months ago but the United Kingdom recently published their regulations and guidelines so we are reviewing some of the differences,’’ said Terry Carkeek, Motorsport NZ technical manager.

``We hope to have something published by the end of November.’’

EVs can already be accommodated in some events but Carkeek says car clubs wishing to invite any battery-compelled cars to an event should contact Motorsport NZ in the first instance.

``We will then provide them with requirements based on the event and the type of vehicle being used. To date, I think we have had three requests all of which we have been able to provide guidelines for,’’ Carkeek said.

``We currently don’t see any need to limit what competition EVs may run in. There is likely to be a requirement for the venue owner to approve the use of EVs to compete on their property and we would also require the approval of the local fire and emergency agency.’’

He said EVs could compete in a separate category but there is also potential to create an equivalency formula to allow competition against conventional powertrains.

``We currently believe that standard, largely unmodified series production EVs, will be relatively easy to include in a number of motorsport disciplines,’’ said Carkeek.

``We also believe that professionally designed and constructed EVs, like Hayden’s Hyundai, should also be relatively easy to include in some events.

``For EVs that have had the high voltage system modified, we will be looking to establish a certification process for those modifications. We have had initial discussions with LVVTA with a view to using their existing standards to accept those vehicles.’’

Kiwi drag racing has been an early EV adopter with a Tesla Model S and Nissan Leaf appearing at recent Meremere Dragway street car events. 

And Taupo engineer Tom Short has built four electric drag racing cars and received a mixed reception in the straight-line sport.

Short has modified classic cars – a Datsun 1200 Coupe, an LH Torana, HT Holden Ute and most recently a 1970 LC Torana GT-R – by installing battery packs and an electric motor.

He achieved early success winning the NZ Drag Racing Association (NZDRA) Super Street national points title in the 2014-15 season with the Datsun. Other than the fact they are near-silent there is little about the performance - or appearance - of Short’s cars that identifies the pioneering role they have played in Kiwi motorsport.

Short said EVs were banned after this title win, re-admitted and then banned again by the NZDRA. At present his car is welcome at events run under International Hot Rod Association (IHRA) rules.

``They [NZDRA] said the ban was for Health and Safety reasons. Some people don’t like change,’’ said Short. 

Another area of New Zealand EV competition has been in moto trials.

A small number of Electric Motion electric trials bikes were introduced several years ago. They’ve been used in competition but are now mainly used by riders for training. 

At present the big area of EV interest is in mini trials and trail riding with the Oset brand of electric off-road bikes becoming a popular choice for 3-12-year-old riders. 

Editor’s note: The end result of a project announced two years ago, Paddon’s car is based on the Hyundai Kona, a compact fully-electric crossover that has been in the market for three years. The rally edition is a world-first for the type and delivers with four-wheel-drive, raised suspension and all the other addenda required for rallying.

It has been developed by the driver and a handful of employees, all hand-picked Kiwi engineers, working from a lock-up at Highlands Motorsport Park at Cromwell. Hyundai New Zealand, the University of Canterbury, Yes Power have supported. STARD, an Austrian racing team that specialises in electric rallycross cars, supplied the battery, inverter and motors. 

 The car is being unveiled tomorrow night in Auckland at Hyundai NZ’s headquarters.
