Sunswift breaks 7 world records

UNSW engineering students tried to break the Guinness World Record with the Sunswift 7 and became the fastest solar powered vehicle. race car More than 1,000 km. Powered by a battery and solar panels mounted on its roof and hood HOUSE He went to a test truck that ran 1,000 km on a single charge in under 12 hours and reached an average speed of 85 km/h. The car, designed and built by students, weighs just 500 kg, about a quarter of a Tesla. To achieve this lightweight body, the team took out a number of features such as airbags and air conditioning systems. Moreover, the Sunswift 7 offers excellent efficiency thanks to its aerodynamic design, the efficiency of the engines and entire drivetrain, and impressively low rolling resistance.

ultimate efficiency

The Sunswift 7 is UNSW’s newest solar-powered car since the first vehicle was produced in 1996. On the test circuit at the Australian Automotive Research Center (AARC) in Wensleydale, Victoria, the car achieved a verified time of 11 hours 52.08 minutes. recording distance. This performance earned the Sunswift Racing team the “Fastest EV over 1000 km on a single charge” record.

The official honor and Guinness World Record certification were awarded a few days later after a team of experts verified the timing information and car telemetry data. As they explained in a press release, the record attempt was not without drama as the team faced a battery management issue that caused the car to stall completely. The team fixed the problem in 14 minutes 52 seconds and was back on track – because the rules of the event required Sunswift 7 not be inactive for more than 15 minutes.

“Two years ago, when we started building this car, everything was crashing and there were a lot of hard times.” But it has been very rewarding to see the whole team come together and make so much progress and get us to this great point. It was a lot of work, a lot of hours and stress, but it was all worth it. This world record is the validation of all the effort put in by everyone on the team,’ Shared Team Manager Andrea Holden, Mechanical Engineering student Works at UNSW Sydney.

For the record attempt, Sunswift 7 completed 240 laps on the AARC’s Highway Track, which equates to more than the driving distance from Sydney to Melbourne. The car only stalled every few hours to allow for a driver change – plus a tire change due to a puncture and annoying battery management repair.

“During this record, energy consumption was just 3.8 kWh/100km, whereas today even the most efficient EVs on the road only reach a rating of 15kWh/100km, averaging around 20kWh/100km.” He mentioned Hopkins. “The Sunswift 7 is not the production car of the future, because we have compromised on comfort and the cost is too high. But we have shown that it is possible if you want to make cars more efficient, more sustainable and more environmentally friendly.’
