"I think a lot of the cars were really complex," Dartmouth College engineering innovation professor John Collier says. "That's the problem that you get into with hybrid [technology] that all of the car companies have finally sorted out. But they've sorted it out with proprietary systems, whether it's Ford, Toyota or Chrysler." Pictured here is Texas A&M's racing team, which won last week's Hybrid Formula competition.

During inspection, judges check to ensure that electrical components are shielded, insulated, waterproofed and controllable. Pictured here is Brigham Young University's racer.

The Dartmouth car uses capacitors rather than a battery to store energy. This makes the car lighter, but there is a trade-off: the maximum charge lasts only about 15 seconds....[More]
The Dartmouth car uses capacitors rather than a battery to store energy. This makes the car lighter, but there is a trade-off: the maximum charge lasts only about 15 seconds. The idea is to use capacitors to store energy every time the driver applied the car's regenerative braking system as it rounded the track's curves and then tap that stored energy to accelerate out of the curve, Collier says.

The team from Sweden's Lund University ran the endurance test's first 20 laps on fuel and the final 20 laps on electric power. "This was a nice demonstration that both systems work," Collier says. Lund received the competition's highest score for endurance, even beating overall competition winner Texas A&M. [Less] [Link to this slide]

Add CommentInteresting. I'm curious to see how the next couple of years go.
Reply | Report Abuse | Link to thisIf I was doing it I would have used a honda 2kw power plant(almost silent(so I hear)) and all electric motors...just a thought for next years competitors....6 hours on a gallon of gas if I can believe what they print...good luck....
