University of New South Wales (UNSW) students set a new Guinness record when entering the competition Bridgestone Biennial Global Sun Challenge. Violet is a solar powered car prototype that incorporates 318 monocrystalline photovoltaic cells.

Sunswift team

Sunswift is the solar running team at the University of New South Wales (UNSW) in Sydney. Set a new Guinness World Record for the youngest energy consumption in a solar car, while driving through Australia.

The team designs and manufactures solar vehicles to compete in the Bridgestone Biennial World Solar Challenge, a 4000 km race across Australia in which universities from all over the world compete.

Created in 1996, the project is run entirely by students and on a non-profit basis. Since its inception, Sunswift has produced six solar cars and has gained a good reputation for rapid prototypes.

The significant achievement they achieved was marked by setbacks that they managed to overcome. They faced rear suspension failures during the Bridgestone World Solar Challenge 2017 and a battery fire in October.

Violet, the solar car.

The students gave it the name of “Purple” to your prototype. In their design, they included strategies to monitor the vehicle’s systems, to make it even more efficient and safer.

Actual energy consumption during the entire journey on average 3.25 kWh / 100 km, which is about 17 times less than the average Australian car.

Traveling an average of 600 km per day, the violet consumed about the same energy per day as that of a standard house. (20 to 24 kWh). The cost of driving the car from Perth to Sydney was also inexpensive, costing less than $ 50.

The students drove 4,000 km in a solar-powered electric car in an effort to break the previous record of 5.5 kWh / 100 km, almost five times more efficient than a Tesla Model 3.

The model is built on a carbon fiber chassis which makes it lighter: it weighs only 360 kg without a driver. He has 318 photovoltaic cells monocrystalline covering 5 square meters of hood, roof and trunk lid.
