Formula Lightning was an electric type of single-seat open-wheel formula racing. Rather unknown to the public, it was held for Colleges of Engineering student teams who built and designed these vehicles which were able to reach speeds up to 143 mph (230 km/h) and competed on both oval and road course type race tracks. These vehicles raced first in 1994 at the Grand Prix of Cleveland CART race and since then have participated in venues across the country. The final official series race was held in October 2004 at Mid-Ohio Sports Car Course.
