Our current car, SR-3 Endurance, debuted at the 2019 Formula Sun Grand Prix. Endurance was built in record time, going from the drawing board to the Circuit of the Americas racetrack in just over a year. From 2019 to 2021, Endurance has received numerous improvements (including a new aerobody and solar array!)

Our third-generation car offers substantial performance and efficiency improvements over SR-2 Odyssey, and continues to provide exciting opportunities for optimization.

Endurance features a complete rethinking of our approach to aerodynamics, with a new carbon fiber monohull aerobody, designed and manufactured in-house. Energy is generated via a state-of-the-art 4 m2 solar array and delivered to the ground via high-efficiency in-wheel motors.
