Kiwi driver Hayden Paddon’s bid to create an EV rally car has put him in a tech race along with his former employer – the Hyundai manufacturing unit.
Paddon is New Zealand’s most successful rally driver – and the one one to win a WRC spherical. His greatest achievement to date is successful the 2016 Rally Argentina. He has introduced an ambition to show the NZ’s hottest EV, the Kona Electrical, right into a rally monster.
However Hyundai Motorsport seems to be on an identical observe to its former driver. On August 7 the corporate additionally introduced it is working on an electrical competitors automobile.
The intention is to disclose this machine to the general public on the Frankfurt Motor Present in September.

The works group has not given any indication if its venture relies on the i20 it competes with on gravel or the i30N, which races on circuits.
Bets are going both manner – the rally group’s successes counsel it could profit most from that discussion board. A teaser video suggests it might be a observe automobile.
That is how Paddon sees it: “They’re miles aside – they’re constructing a observe automobile, one thing completely totally different from our automobile.”
Paddon’s plan is to be testing subsequent April, competing later within the 12 months then taking an improved second automobile into the NZ championship in 2021.
And, sure, he is driving – in addition to persevering with his bid to re-enter the WRC, most likely with Ford-aligned M-Sport.
Hyundai New Zealand, the College of Canterbury and an Austrian firm whose four-wheel-drive electrical competitors automobile appears positive to offer a suggestion are additionally concerned.
Paddon’s pitch has made huge headlines, right here and abroad – so maybe it’s going to attain consideration of Hyundai Motorsport, whose works rally group based mostly in Germany dropped the Kiwi after the 2018 season.
Both manner, the Paddon and works’ tasks are operating forward of the official strikes to introduce electrical drivetrains into the best stage of full-scale rallying.
The worldwide motorsport physique, the FIA, has introduced an all-EV rallycross sequence for 2021 but it surely has gone in a special course for the WRC.
For that competitors it has okayed a five-year homologation cycle heading towards a wholesale EV integration.
In June the physique’s world council gave the inexperienced gentle to a primary step – from 2022, WRC automobiles should run with a spec electrical energy unit hooked up to their very own inner combustion engines.
All automobiles will share a lot of their hybrid components for the primary three years, and electrical technical developments can be allowed starting in 2024.
The change will not occur in a single day for many groups both, because the FIA will permit a mixture of hybrid and totally electrical rally automobiles on the identical stage till everybody has utterly changed inner combustion engines.
The final word imaginative and prescient is for these powertrains to present automobiles further energy from recovered power in sure rally phases and run on full electrical energy throughout downtime and in cities.
Paddon doubts WRC might ever realistically help totally electrical automobiles; the present format of four-day occasion with a number of phases on every day is simply an excessive amount of for any current tech to deal with.
Discuss of Paddon’s automobile having 600kW suggests requirement for greater than a rework of the Kona EV drivetrain, which makes 150kW and 395Nm and runs on a 64kWh battery. Additionally, the highway automobile is entrance drive – for rallying, four-wheel-drive can be carried out, the Kiwi has confirmed.
The best challenges are to do with the batteries. Rally automobiles must be gentle and hardy; battery units are heavy and who is aware of how properly they’ll stand as much as the crash-bash? Batteries that run exhausting additionally run sizzling – and, in fact, the driving strategies for rallying would additionally possible be the quickest solution to deplete a battery.
It is honest to imagine Paddon will not count on his automobile to match the common Kona Electric’s 450km optimal range, but it surely should final a nationwide spherical, which normally delivers 150-200km in particular stage distance, plus a minimum of 100km touring.
Paddon has acknowledged it is no simple highway, however he is characteristically chipper.
“It is the way you harness that efficiency for rallying, for instance with torque vectoring for gravel/low grip conditions and the vary wanted to finish a full day’s rallying.”
Confidence for a venture that can eat the total power of a specifically shaped PRG division – Various Vitality Motorsport Growth (AEMD) – based mostly at Highland Motorsport Park in Cromwell is boosted by having highly effective backing, together with from an Austrian firm that has proved its mettle.
Three years in the past Stohl Superior Analysis and Growth, owned by former world Group N champion Manfred Stohl (a Rally NZ common for a number of works groups), revealed the world’s first totally electrical rally/rally cross automobile.
Primarily based on a transformed Peugeot 207 Tremendous2000 bodyshell, STARD’s four-wheel-drive mannequin has 410kW/780Nm, outputs then similar to the ability of a World Rallycross Supercar. It might attain a prime pace of 195kmh.
Though that efficiency solely allowed for operating at most energy for 15 minutes, the 1250kg mannequin might obtain 90 per cent of its full torque in an astounding 40 milliseconds.
Stohl recounted it was “essentially the most mind-blowing automobile” he had pushed, including that the impact of quick and steady torque meant “from nothing to 195kmh makes you are feeling such as you’re on a large rubber slingshot into area.”
The STARD automobile is not going to develop into the premise of Paddon’s machine as a result of, the Kiwi says, tech has moved on significantly since then. Nonetheless, STARD’s experience will drive the Kona venture, with the Austrians offering a battery and likewise popping out right here to take part within the bodily testing.
For his half, Paddon says he’s passionate in regards to the venture which can showcase PRG’s capabilities with their new mind-set about EV applied sciences and the way these can apply to the game.
“This… can be a showstopper by way of efficiency and can do issues in another way to electric-powered competitors automobiles seen thus far.
“Various power powerplants are in a short time evolving within the consumer-focused automotive sector, however the identical developments will not be as widespread in motorsport and definitely not in rallying.
“The extra I thought of it, the extra potential I might see to align prime tier rallying with the know-how goals of main car producers.”
Paddon Rallysport is NZ’s most profitable rally group and previous achievements embrace creating Hyundai’s first AP4 rally automobile.
