Georgia Tech Students Unveil Sun-Powered Audi TT for World Solar Challenge

A team of students from Georgia Tech recently rolled out a hyper-modified electric Audi TT that runs on electricity harvested from the sun. The solar-electric hybrid was designed to participate in the World Solar Challenge in Australia, which challenges designers to race for thousands of miles using solar power.

Who said students are useless layabouts? Not me, that’s for sure – especially when they take time out from drinking beer and watching TV to convert an Audi TT into a solar-electric hybrid. The Georgia Tech students presented their car at the Buckhead Eco-Collection and showcased its features.

The electric car is equipped with two batteries, one of which is charged via solar panels. This battery is responsible for running the power brakes, windows and power steering. The other battery runs the car’s drivetrain and can be charged from an electric socket. A 120-volt battery pack powers the Audi engine, giving it a 70-mile radius between charges. The Solar Jackets plan to add a lithium-ion battery system to the car that will increase the travel radius to 140 miles.

The World Solar Challenge, which was started way back in 1987, challenges solar-powered vehicles to race thousands of miles in order to advance solar and electric vehicle technology. The race brings together the world’s top engineering colleges and this year’s challenge looks to be the closest yet. The six-day race will take place in October this year, and will go from Darwin to Adelaide. Over 50 students are said to be working on their college’s entry.

While the vehicle is a remarkable feat of engineering, we’re not entirely comfortable with the fact that the battery that powers the breaks could potentially go flat in drab weather

    This vehicle is what the Solar Jackets call a solar-assisted electric vehicle (SAEV). It is incapable of competing in the World Solar Challenge.

    The team is building a more traditional solar racer, which doesn’t look anything like an Audi TT and almost certainly doesn’t have power brakes, steering, or windows:

    Also, your fear of losing your breaks[sic] in drab weather is unfounded. Your source article quotes one of the team members as saying:
    the car is capable of anything the standard production car is, including highway travel at night and cruising around town on a rainy day.
    This would indicate that the solar-powered functions are able to use the stored energy in the 12V system to function, and are not dependent on the solar panels.
