The car, which was designed and built by engineering students from the University of New South Wales (UNSW), departed Sydney, Australia, on Sept. 20 and will travel about 2,700 miles (4,300 kilometers) to Darwin, on the continent's northern coast. This scenic route allows the team to test the car, and serves as a regional outreach tour, introducing their fellow highway drivers to the car's futuristic design.

The race will take them from Darwin in the Northern Territories to Adelaide in South Australia, covering 1,877 miles (3,021 km). Though the event is scheduled to last from Oct. 8 to Oct. 15, the winner is expected to cross the finish line in Adelaide's Victoria Square in the early hours of Oct. 12, officials with the World Solar Challenge announced in a statement.
Violet is the sixth iteration of a solar-powered race car produced by UNSW's Sunswift team, which formed in 1995 to compete in the World Solar Challenge. Described by UNSW representatives as "a four-seater sedan" and larger than previous generations of Sunswift's solar race cars, Violet was deliberately crafted to resemble commercially produced vehicles, in order to showcase solar technology as a potential energy source for practical, daily use in transportation, Sunswift representatives explained on the group's website.
With a shell made of carbon fiber, the car weighs about 880 lbs. (400 kilograms) and it uses about 7 kilowatts of horsepower at 68 mph (110 km/h) — "as much power as a four-slice toaster," Sunswift team leader Simba Kuestler said in a statement.
Clean energy and comfort
Lined with solar panels on its roof and hood, Violet can travel for 497 miles (800 km) on power generated by its rooftop panels alone, and it can run for 249 miles (400 km) on solar power stored in its lithium batteries, with a maximum speed of 81 mph (130 km/h), according to UNSW representatives.
However, Violet was also designed for comfort. It includes numerous features associated with consumer vehicles, such as an entertainment system, storage space in the front and rear, reverse camera parking sensors, air conditioning, an interactive dashboard display with GPS "and many more," according to the Sunswift website.
"There's even Wi-Fi aboard," Kuestler added.
But once the race begins, more than Violet's Wi-Fi performance will be put to the test. Teams will drive as far as they can until 5 p.m. local time, when they must stop and camp for the night, wherever they may be, race officials explained on the World Solar Challenge website. There are also seven mandatory checkpoints where teams can perform basic maintenance and receive updates about their field position and weather conditions, according to the website.
Violet suffered a minor mishap during recent road tests prior to the team's departure for Darwin, when a suspension bolt broke during braking tests. But the Sunswift team redoubled their efforts to fix the damage, reinforce the car's structure and still meet the deadline for the race, Mark Hoffman, UNSW's dean of engineering, said in a statement.
"That's what an engineering degree should be about — learning about demanding, real-world challenges," Hoffman said.
