From GM press: The GM Sunraycer solar-powered vehicle was a radical step in aerodynamic design and won the world’s first solar-powered vehicle competition, the 1,950-mile World Solar Challenge Race.
Powered by 7,200 solar cells that covered an area of 90 square feet, it could reach a top speed of 45 miles per hour on a sunny day using solar power alone. In cloudy conditions, it used a battery for extra power and acceleration, giving it a top speed of 60 miles per hour. It measured 19.7 feet long, 6.6 feet wide and only 3.3 feet high. Total weight was only 360 pounds. Many of its technological and design innovations later influenced the development of GM’s EV1 electric car and the Chevrolet Volt E-Flex concept.
