The Sunswift eVe solar-powered car broke a 26-year-old land speed record for electric vehicles

The Sunswift eVe solar-powered car broke a 26-year-old land speed record for electric vehicles on Wednesday at the Australian Automotive Research Center in Victoria. While the record still has to be ratified by the Fédération Internationale de l’Automobile, it would make eVe the fastest electric car to ever compete a 500 km set distance course by a significant margin, Gizmodo reported. The previous record, set in 1988, was an average speed of 73 kilometers per hour; the Sunswift eVe reached 100 km per hour average over the 500 km course.

Sunswift eVe, designed and built by students at the University of New South Wales, seeks to overcome the traditional obstacles that have impeded solar-powered cars, namely, offering both speed and range in the same vehicle.

“There are many solar cars out there with a long range, and many other solar cars capable of even higher speeds,” Rob Ireland, business team leader at Sunswift, told International Business Times. “However, we’re trying to do something ground-breaking and overcome both.”

The zero-emission solar and battery storage electric vehicle is capable of covering 800 km on a single charge and has a top speed of 140 km per hour (87 miles per hour). The car’s solar panels have an 800-watt output and when the sun isn’t shining, eVe relies on its battery pack, reducing drivers’ range anxiety. The car’s motor, “supplied by Australian national science agency CSIRO, operates at 97 percent efficiency, meaning eVe consumes as much power as a kitchen toaster,” according to IB Times.

For Wednesday’s record attempt, the solar panels on the roof and hood were used to charge the battery, but were covered for the actual run, as the attempt had to be completed on a single charge.

While the Sunswift eVe is not fully road legal, the team believes that isn’t far out of reach, telling Renew Economy they hope to have the vehicle on Australian roads within the year as “a symbol for a new era of sustainable driving.” And Ireland said the practicality of the two-seat, four-wheel car is unmatched among solar-powered vehicles.

In the run-up to their attempt at the land speed record, project director and third-year engineering student Hayden Smith explained to Renew Economy why it was so significant. “Five hundred kilometers is pretty much as far as a normal person would want to drive in a single day,” Smith said. “It’s another demonstration that one day you could be driving our car.” More
