Mitsubishi i

Two Mitsubishi i electric vehicles were "raced" at Indianapolis Motor Speedway last week by professional race car drivers Roger Yasukawa and Johnny Miller. The contest? To test how quickly the EVs could be recharged with Level 3 quick-charge stations make by Contour Hardening.

Yakusawa and Miller reached top speeds of about 56 miles per hour in the i EVs as part of the exhibition, which was filmed and available to you after the jump. The drivers "completed" the so-called EV500 in about 12 hours, Road & Track reported.

Contour Hardening organized the event to get a better idea of how quickly driving range could be added to the EVs with short charge cycles using higher-powered EV charging stations.

In late November, Mitsubishi started selling the i – known as the i-MiEV overseas – on the West Coast and in Hawaii, and will expand sales nationwide in mid-2012. The car, which is priced in North America at about $6,000 less than the $35,200 Nissan Leaf battery-electric vehicle, offers an EPA-rated single-charge range of about 62 miles, or 11 miles fewer than the Leaf's. Mitsubishi has sold about 16,000 i-MiEVs since debuting the model in Japan in July 2009.

In November, the U.S. Environmental Protection Agency and Department of Energy named the i the most fuel-efficient vehicle sold in the United States. The federal agencies' latest edition of their Fuel Economy Guide rates the i at 112 miles per gallon of gasoline equivalent. The Leaf came in second at 99 MPGe.
