Students from the University of New South Wales (Australia) have created the most economical car in the world. To drive 4100 km from Perth to Sydney, it only needed $50. 
Violet (that’s the name of the car) is equipped with an electric motor, and its hood and roof are covered with solar panels. However, there are also battery cells, as the energy from the sun is insufficient. The electric car traveled approximately 600 km daily, which required 20-24 kWh of electricity – five times less than the Tesla Model 3.
However, Violet still needed to be recharged at night, and over six days, it accumulated those same $50. 
This is the third attempt to set a record with Violet. In 2017, the car’s rear suspension broke, and in October 2018, the battery caught fire. Now the achievement will be recorded in the Guinness Book of Records.
