College students from the College of New South Wales (UNSW) have taken their Sunswift 7 solar-powered electrical automobile (EV) and achieved a provisional Guinness World Document for being the quickest EV over 1000km on a single cost.
The staff was in a position to clock up 1000km in 11 hours, 53 minutes, and 32 seconds at a median pace of 85km/h throughout its world file try on the Australian Automotive Analysis Middle (AARC) in Victoria.
The Sunswift 7 accomplished 240 laps of AARC’s Freeway Circuit, and achieved a median vitality consumption of three.8kWh/100km. For context, the Tesla Model 3 RWD has a claimed mixed vitality consumption of 13.4kWh/100km.

The EV solely stopped for a change of driver each few hours, in addition to as soon as for a tire change as a consequence of a puncture. The staff additionally had a battery administration concern at one level in the course of the file try which introduced the automobile to a whole cease.
The principles of the occasion acknowledged the Sunswift 7 couldn’t be stationary for greater than 15 minutes at a time. It took the staff 14 minutes and 52 seconds to repair this concern and get it again on monitor.
The official Guinness World Document will likely be conferred as soon as timing data and automobile telemetry information has been analyzed and confirmed by a staff of specialists.
The Sunswift 7 is the newest UNSW student-designed and constructed solar-powered EV in an extended line that dates again to 1996.
This newest iteration weighs in at round 500kg, has a hyper aerodynamic exterior design, and “extremely low” rolling resistance. It isn’t highway authorized and would not have options corresponding to airbags or air-conditioning.
The staff principal, Professor Richard Hopkins, received 4 Components 1 titles in his earlier position as head of operations at Purple Bull. He ranks this file simply as extremely although.
“Let’s keep in mind, these should not the very best paid skilled automobile makers in Stuttgart working for Mercedes,” mentioned Professor Hopkins.
“It is a bunch of very sensible amateurs who’ve taken all of the substances and put it collectively in an excellent means.
“This staff has centered on final effectivity to be able to break this world file. They’ve proven what’s in the end achievable in the event you consider aerodynamics, and rolling resistance and the usage of sensible supplies,” Professor Hopkins added.
“It feels very bizarre to assume that we have helped to make one thing that is the very best in the whole world,” mentioned Sunswift staff supervisor and UNSW Sydney mechanical engineering pupil Andrea Holden.
“Two years in the past, after we began to construct this automobile, every little thing was going into lockdown and there have been quite a lot of tough moments.
“However it’s been so rewarding to see the entire staff come collectively and make a lot progress and get us to this superb level. It was quite a lot of work and quite a lot of hours and quite a lot of stress, nevertheless it’s all been value it.”
