There’s a contest underway to build 100-mile-per-gallon (mpg) cars that are practical and feasible for mass-production. Known as the Progressive Insurance Automotive X Prize, it will award $10 million to whomever can crack the 100-mpg puzzle and best demonstrate the achievement during cross-country races. When the races start in 2009, I’ll be behind the wheel of a sporty two-seater that will be as cool as it will be fuel-efficient. Through a series of Mother Earth News articles and updates online, you can come along for the ride.
this is a worthy challenge
