Challenger Class

Challenger Class cars tend to be smaller and sleeker, with improved design vision. A great deal of lateral thinking is required to meet conflicting needs of maximising the solar collection area, minimising aerodynamic drag and other design regulations needed to qualify for the Challenger Class and contest the World Solar Cup.

The 2025 design parameters for Challenger Class solar cars:

Max. Length: 5.8m

Max. Width: 2.3m

Max. Solar Array: 6m²

Wheels: At least 3

Driver: 1
