The Antro Solo from Hungary is a gas-electric hybrid car with a unique power arrangement that also utilizes solar energy. When all power sources fail, you can even peddle your way.
The Antro Solo seats three people, with the driver in middle. It achieves over 100 mile per gallon and can go 87 mph. In order to keep its weight below 600 pounds (270kg), Antro Solo is built entirely out of carbon fiber and composites.
Currently in prototype, the $18,000 eco car is projected to be available in 2012.
