Supercars with style

"The super-efficient cars of the future don't all have to look like glorified motorcycles. Illuminati Motor Works' swoopy Seven, for example, looks as if it were beamed down from a retro "Dick Tracy" universe, complete with gull-wing doors and an aerodynamic teardrop profile. The Seven was among, um, seven cars that went through fuel-efficiency road tests today at the Michigan International Speedway in Brooklyn, Mich., as part of the Knockout stage of the $10 million Progressive Insurance Automotive X Prize competition."
