Sunswift 7 – More Than 1000 KM Without Recharging
A team of engineers with Sunswift 7
A team of engineers from Australia is claiming a new world record for their Sunswift 7 electric car. The solar-powered car recently passed a test cycle in which it covered 1,000 km on a single charge in less than 12 hours. The Sunswift 7 electric car weighs only 500 kg. This is about a quarter of the mass of a typical Tesla car.
Of course, in order to invest in such a small weight limit, engineers had to abandon the air conditioning system, ABS brakes, airbags, wipers and other functions. Instead, engineers focused on aerodynamic efficiency and rolling resistance. If the Tesla Model S has an aerodynamic drag coefficient of 0.208, then the Sunswift 7 has this indicator of only 0.095.
The team spent two years creating the Sunswift 7, setting a goal to set a Guinness World Record and demonstrate the fastest solar–powered electric vehicle that can cover a distance of more than 1,000 km. An attempt to set a record was recently made at the Highway Circuit test track at the Australian Automotive Research Center, when the Sunswift 7 overcame 240 laps on a single charge.
To overcome the 1000-kilometer distance, it took 11 hours, 53 minutes and 32 seconds, and the average speed was 85 km / h. The change of drivers took place every few hours. There were several problems on the way to the finish line: with battery management and a punctured tire.
So far, the Sunswift 7 is unofficially considered the fastest electric car, covering more than 1000 km without recharging. The team is waiting for official confirmation of the time and data of automotive telemetry to receive a certificate of the Guinness World Record.
Within the framework of this record, energy consumption was only 3.8 kWh/ 100 km, whereas today even the most efficient electric vehicles on the roads reach a rating of only 15 kWh/ 100 km, and the average is about 20 kWh / 100 km..
