Brits Go Green with Eco-M 100 MPG Sports Car
Eco-M, a bare-bones sporty car with a 1.4-liter gasoline engine. The car will be able to sip fuel and still go fast, capable of far greater than 100 miles per gallon because of its lightweight carbon fiber construction.
I wonder if cars like this will lead to rally-races where the winner is the team that can drive above a certain speed for the most number of laps on a fixed amount of fuel. That would be an amazing engineering challenge with a lot of real world value.
