Pushing the GT Pro to its thermal and dynamic limits on a closed circuit.
Willow Springs' Big Willow circuit is 2.5 miles of high-speed elevation changes and off-camber corners. It's designed to punish every weakness in a vehicle's chassis and powertrain. We ran 40 laps over 6 hours.

Lap times settled into a consistent 1:42 — competitive with 600cc sport bikes despite our significant weight penalty. The instant torque more than compensated on corner exits, and the low center of gravity (battery pack below the seat) gave us confidence in high-speed direction changes.
Thermal management was the focus. After 8 consecutive hot laps, motor temperature plateaued at 152°C and the controller held at 89°C. The system never entered thermal derating. This validated our oversized cooling system design.
