Since 2008, Georgia Tech Solar Racing students have designed, manufactured, and raced five generations of solar-powered vehicles—evolving from single-seat Challenger class cars to North America’s first four-passenger Multi-Occupant solar race car to compete in FSGP.
SR-4, Aurora
Our current car, SR-4 Aurora, is our first multi-occupant vehicle. This major shift in vehicle design has provided our team with engineering challenges and opportunities for innovation. After several years of development, Aurora made its Formula Sun Grand Prix debut in 2025 as the first ever North American solar car to race with four passengers, earning a 3rd place podium finish.

SR-3, Endurance
Our third-generation car, Endurance, debuted at the July 2019 Formula Sun Grand Prix. Endurance was built in record time, going from the drawing board to the Circuit of the Americas racetrack in barely over a year. Nonetheless, Endurance offered substantial performance and efficiency improvements over Odyssey, and in 2021 became our first vehicle to complete the entirety of the American Solar Challenge route.

SR-2, Odyssey
Our second-generation car, SR-2 Odyssey, competed in the American Solar Challenge 2018 after having qualified at the Formula Sun Grand Prix. This vehicle features an aluminum 6061-T6 frame, carbon fiber aerobody, lithium-ion batteries, two 98.4% efficient motors, carbon fiber wheels, and 20.9% efficient single-junction solar cells generating 1.2 kW of power.

SJ-1, Endeavour
Endeavour was the first fully functioning, 100% solar-powered car raced by Georgia Tech. Silicon solar cells (17% efficient) are attached to the top of the aerobody made from carbon fiber. Endeavour weighs in at a little less than 900 pounds with driver and has seen top speeds of 45 mph. All of this runs on about 1.0 kW, or roughly the same power as a hair dryer.

Audi Project (2008)
The idea behind the first Georgia Tech solar-powered project was to take apart a car and reconfigure it with only electrical components. The team removed the combustion portions of the engine and integrated the circuitry required for power via solar energy—inspiring generations of solar racers.
