Aptera at Progressive?s X-Price

The X Tracer leads the pack with some impressive mpg results? The Knockout Stage, which began June 21, whittled the field of competitors down to a choice few. Every event could have meant potential elimination for any of the remaining 22 teams. Successful completion of all events except the 'Highway Acceleration' and 'Lateral Acceleration' Tests was required for vehicles to be eligible to compete in the Finals Stage of the X PRIZE in August and September.
