Trev (two-seater renewable energy vehicle)

Trev has been entered in the around-the-world Zero Race. See the Team Trev web site for details.

In October 2008, Trev featured on a New Inventors special, Re-Inventing the Wheel. Video is available on the New Inventors web site.


Suppose you decided that you weren't going to use fossil fuels anymore. How would you get around?

Solar racing cars are able to travel 750 km per day, at highway speeds, powered only by sunlight. Surely it is possible to use similar technologies to build a car in which you could do your daily commuting, but without the noise and pollution of a petrol engine.

Staff and students at the University of South Australia have designed and built such a car—Trev. Its features include:

Most importantly, it uses less than 1/5 of the energy required by a conventional car, and can be recharged using electricity from clean, renewable sources such as solar and wind.

And it doesn't look too bad...



In October 2007 we drove Trev from Darwin to Adelaide in the Greenfleet Technology Class of the World Solar Challenge. For most of the journey, we drove 80 - 120 km at speeds of 80 - 90 km/h before stopping to recharge from a generator. We completed the 3020 km trip in just over 6 days.

Our energy consumption was 6.2 kWh/100 km. Recharged from solar, wind or hydro, there are no emissions.

Electricity costs about $0.18 per kWh. The cost of recharging Trev is 1.1 cents per kilometre, so the entire journey cost us $33 of electricity

It makes petrol look silly.

For more information, see our Q and A about Trev. We also have images and movies.
