Challenger Class
AERODYNAMIC MASTERPIECES 
The Challenger Class is the classic solarcar born of original concept: Build a car capable of driving from Darwin to Adelaide on the silent power of nature. They are required to travel from Darwin to Adelaide (c.3000km) in a single stage, with teams stippling and making camp in the desert wherever they are at 5pm (NT time). It is an extreme endurance challenge where the secrets of success will include efficiency, reliability and attention to detail.
The 2023 design parameters for Challenger Class solar cars:
Max. Length: 5m
Max. Width: 2.2m
Max. Solar Array: 4m2
Wheels: At least 3
Driver: 1
Stages: Single stage, Darwin to Adelaide
What do we observe from Challenger Class Entries?
The smaller solar collector area and broader design envelope included in recent year's regulations allow a greater variety of designs. Expect to see some differently shaped cars! Challenger Class cars tend to be smaller and sleekr, with improved design vision.
A great deal of lateral thinking is required to meet conflicting needs of maxmising the solar collection area, minimising aerodynamic drag and other design regulations needed to qualify for the Challenger Class and contest the World Solar Cup.
