The guys at Shelby Supercars know a thing or two about defying odds and breaking records. Back in September, the fledgling company's 1,183-HP Ultimate Aero jacked top-speed bragging rights from Bugatti's 16-Cylinder, $1.8 million Veyron. But the Aero's limited to just 50 examples, so the drawing board is particularly important to the West Richland, Washington-based manufacturer. Along with the 220 mph luxury sedan it's got in the pipeline, SSC has announced plans to build a top-speed, 100 percent green supercar.
