The University of Kentucky Solar Car Team is an independent, student-led project that operates as part of the University of Kentucky College of Engineering. The team's primary goal is to compete in the American Solar Challenge (held every two years) and the Formula Sun Grand Prix (held every year) over the summer, but they also perform outreach events in which they display and discuss their car with nonmembers.
The team's mission is to design, build, and race solar-powered cars while developing team members through practical experience with much-needed hands-on experience outside their demanding course load, all while contributing to STEM outreach in the Bluegrass region. Over the past 20 years, there have been 6 solar cars built, each following naming convention of Gato del Sol followed by a Roman numeral. Gato del Sol VI is the current solar car in use, first formed in 2017.
Membership is open to all University of Kentucky students (Undergraduate and Graduate), professors, and members of the community.
The Solar Car Team strives to:
In 2008, the Solar Car Team completed its first North American Solar Challenge, finishing 11th of 15 teams in the 2400 mile race from Plano, TX, USA to Calgary, AB, Canada. In 2009, the team placed 2nd (out of 11 teams) in the Formula Sun Grand Prix at the Texas Motorsport Ranch in Cresson, TX. In 2010, the team placed 9th in the American Solar Challenge, from Broken Arrow, OK to Naperville, IL. The team celebrated their 20th anniversary in 2019 and secured the track record lap time at Circuit of the Americas for solar cars at 3:48.975. In 2021, the team scored its best results to date: first place in FSGP 2021 and second place and most improved in ASC 2021.
The team began in 1999 when University of Kentucky sophomore, Bianca McCartt, approached then Assistant Professor Lyndon Scott Stephens to serve as founding advisor. Together, McCartt and Stephens envisioned a student led organization that focused on solar-based renewable energy. The first UK solar car was originally named Firefly and was a heavy, lead acid battery leviathan that competed as a demonstration vehicle in the organizations first event. Shortly thereafter, then student, and now Professor of Mechanical Engineering, Dr. Christine Trinkle proposed the perennial name for the car, Gato Del Sol ("Cat of the Sun"), and the solar car team had a name befitting the University of Kentucky mascot "the Wildcats". With generous support from benefactors including UK Alums Ralph G. Anderson and Billy Harper, and many businesses including Hyro Aluminum, Inc., Toyota, Sunpower, and Stone Farm (owner of 1982 Kentucky Derby Winner Gato Del Sol), 6 generations of solar cars (Gato I-VI) have resulted with success along the way. The team was the winner of the Sportsmanship Award in the 2003 North American Solar Challenge, finished 2nd at the 2009 Formula Sun Grand Prix and finished 3rd at the 2019 Formula Sun Grand Prix. It has participated in more than 10 race events and hundreds of special events including the annual Kentucky State Fair and regional parades. As of 2020, it is estimated that more than 1500 students from majors across the university have participated in the Solar Car team since its founding 21 years ago. More importantly, through its outreach and education efforts the team has exposed renewable solar energy technology to countless thousands.

A solar car is a solar vehicle for use on public roads or race tracks. Solar vehicles are electric vehicles that use self-contained solar cells to provide full or partial power to the vehicle via sunlight. Solar vehicles typically contain a rechargeable battery to help regulate and store the energy from the solar cells and from regenerative braking. Some solar cars can be plugged into external power sources to supplement the power of sunlight used to charge their battery.
Solar car racing refers to competitive races of electric vehicles which are powered by solar energy obtained from solar panels on the surface of the car. The first solar car race was the Tour de Sol in 1985 which led to several similar races in Europe, US and Australia. Such challenges are often entered by universities to develop their students' engineering and technological skills, but many business corporations have entered competitions in the past. A small number of high school teams participate in solar car races designed exclusively for high school students.
