Other battery chemistries are allowed but the weights are restricted accordingly to maintain the 1kwh capacity limit. This type of lightweight car appeared in Australia in the late 1970s and was warmly embraced and introduced into American culture as early as 1980.

is an electric vehicle endurance racing competition. The winner is determined by who traveled the farthest in two 1-hour races on 1kwh of battery power in each race. The cars are generally 3 wheeled, hand built vehicles although some kit-built cars have been available in the past. Cars are similar in

Electrathon racing started in
England, spread to Australia, and arrived in the United States in 1990. The basic format is to determine which car can travel the furthest in one hour within the limitations of battery weight and other factors mentioned above. Design teams must compromise speed in order

In 2007, the Utah Salt Flats Racing
Association invited several Electrathon Competitors after adding an Electrathon class. It used the same vehicle design rules, but instead of a 60 minute endurance event, it's a straight line top speed event on a one mile course. Speed was/is measured using a 30

The relatively low cost of the electrathon racing has made the sport a popular activity for high school age students worldwide who learn skills related to design, problem-solving, teamwork, mathematics, physics, and electricity. Prizes are awarded for high school, college and open divisions, and

Races are held on parking lots, road courses, and oval speedways, but size is a major factor, as cornering friction decreases efficiency. At present, the world record for distance travelled in one hour is 62.05 miles (99.86 km), set in July 2009 on the 5-mile (8.0 km) oval at the Ford

Electrathon class vehicles are principally defined and constrained by length and width (12 feet long and 4 feet wide or 3.6 m × 1.2 m maximum) and by battery weight and chemistry (73 pounds or 33 kilograms,
