POWER BEGINS
WITH THE SUN.
The solar array supplies energy to the vehicle while the electrical system manages generation, storage, protection, and distribution.

ABOUT
ENGINEERING BY DOING
THE CAR IS
THE CLASSROOM.
We learn engineering by building something that has to work outside the classroom.
Electrical decisions affect packaging. Mechanical decisions affect wiring. Software determines what the driver sees. Every subsystem eventually meets at the vehicle.

CONTROL IS
DISTRIBUTED.
Custom electronics connect vehicle controls, sensors, driver displays, power systems, and telemetry across the car.
DATA REACHES
THE DRIVER.
Vehicle information is collected and presented to the driver so operating decisions can be made while the car is moving.
EVERY SYSTEM
MEETS HERE.
Electrical, mechanical, structural, software, and race operations become one system when the vehicle reaches the road.
