Electrifying drive sets new energy benchmark

Science - Energy

Internode managing director, Simon Hackett, has driven the world’s first fully-electric production supercar 3000 kilometres from Darwin to Adelaide at a cost of $126.11, or four cents a kilometre, and equal to fuel use of 1.6 litres per 100 kilometres.

The ISP boss and founder said the energy consumption of his car – a Tesla Roadster – was measured in watt hours per kilometre (Wh/km), which translates into fuel-equivalence with the online calculator.

The cost of the journey at $126.11 using 100 percent GreenPower was calculated at on-peak rates, and according to the consumption report, using off-peak GreenPower .that cost could be as low as $69.11 (2.2 cents per km).

According to Hackett, the Tesla’s best energy performance was on its record-breaking trip when it travelled more than 500km on a single charge from Alice Springs to south of Marla in South Australia, with the car consuming 108 Wh/km – equal to a fuel-powered car consuming 1.22 litres of fuel per 100 km. “That’s 193 miles per gallon in US measures,” Hackett said, adding that “in addition to its spectacular energy efficiency, the Roadster produced no carbon emissions during the epic road trip.”

Hackett described the Tesla’s energy efficiency figures as “amazing,” and said that “in effective terms, this EV (Electric Vehicle) is more than twice as efficient as any petrol or diesel car on the road – no contest.

“We feel that we have tested the Roadster in a very harsh environment indeed – and in that environment, it has come through with flying colours. We couldn’t be happier about the results of our efforts.”
