Cal State LA Solar Car Team
The Cal State LA Solar Car Team is an engineering team from California State University, Los Angeles. The team develops the Solar Eagle, a series of solar cars that have taken part in solar car races in the United States and in Australia.
Solar Eagle
- 1990: Solar Eagle - GM Sunrayce USA: 4th place.
- 1990: Solar Eagle - World Solar Challenge: In the top ten.[1]
- Now on display at Cal State LA.
The Solar Eagle is a world-class, solar powered car designed and built by the Cal State L.A. School of Engineering & Technology students, faculty and staff.
In July, the Solar Eagle placed fourth in the 1,643 mile GM Sunrayce. California's number one solar car finished ahead of 28 other colleges and universities including such prestigious institutions as MIT and Stanford.
The team's out-standing capabilities will be further demonstrated at the November 1990 World Solar Challenge in Australia.

Solar Eagle II
- 1993: Solar Eagle II - GM Sunrayce USA: 3rd place;
- 1993: Solar Eagle II - World Solar Challenge: 13th place.
- Now on display at the California Science Center in Los Angeles.
In June 1993, the Solar Eagle II placed third in the 1000 mile SUNRAYCE 93 — a cross-country race from Dallas, Texas to Minneapolis, Minnesota. The Solar Eagle II started the race in the pole position having qualified with the fastest time. Solar Eagle II finished ahead of 33 other universities including such prestigious institutions as Stanford, George Washington University and UC Berkeley. The car and team were honored with a second place award in Technical Innovation for Chassis Design, Propulsion and Aerodynamic Systems by the SUNRAYCE 93 judges and they received a third place award from the Society of Automotive Engineers (SAE) for Design Excellence in Engineering Safety. In November 1993, the Solar Eagle II gained international recognition by placing thirteenth out of a fifty-four car field, and became the fourth U.S. team to cross the finish line at the 1993 World Solar Challenge, a grueling 1,882 mile race across the Australian outback.
Cal State L.A. was selected as one of 30 universities granted entry in the SUNRAYCE 95 competition and work will soon begin revamping the Solar Eagle II for that event.

Solar Eagle III
- 1997: Solar Eagle III - GM Sunrayce USA: 1st place.
- Now on display at Cal State LA.
Solar Eagle III is the third chapter in Cal State L.A.'s exciting trilogy of solar-powered electric vehicle design projects. Engineered by students under the guidance of faculty and staff, the Solar Eagle III represents the culmination of learning, trial and redesign gleaned from the University's first two solar race cars, the Solar Eagle and the Solar Eagle II.
On Saturday, June 28, 1997, the Solar Eagle III won the prestigious Sunrayce 97, the national intercollegiate solar car race, crossing the Colorado Springs finish line under fittingly sunny skies. Setting a Sunrayce record for average speed of 43.29 mph, Cal State L.A. finished nearly 20 minutes ahead of second-place Massachusetts Institute of Technology (MIT). The combined team of Stanford University/UC Berkeley finished third. Texas A&M, whose team used the molds from Cal State L.A.'s Solar Eagle II to build their entry, the MACH V, finished fourth.
Solar Eagle III's first-place finish at Colorado Springs marked the end of ten days of exciting intercollegiate solar car racing. Throughout the competition, Cal State L.A., MIT and Stanford/ UC Berkeley jockeyed in the top three positions. In the end, good design and solid engineering won the race: the beautifully built Solar Eagle III never broke down during the entire 1,230 mile course, . (The car never even had a flat tire.)
The Texas A&M MACH V was the only other car in the field that completed the entire event without an unscheduled stop. The Texas A&M car was built entirely by the students in just 1 year. It was no mistake that robust design was a significant contributor to a strong finish.
The Solar Eagle III's technical specifications, described below, give the blueprint for a national champion — a world-class, space-age solar vehicle, meticulously refined and built on the successes of its first two solar cars, Solar Eagle and Solar Eagle II.
