Optional new rules require fewer solar cells

Entrants to the 2007 race chose between racing in the Adventure and Challenge classes.

Challenge class cars were restricted to 6 square meters of solar collectors (a 25% reduction), driver access and egress were required to be unaided, seating position upright, steering controlled with a steering wheel, and many new safety requirements were added. Competitors also had to adhere to the new 130 km/h speed limit across the Northern Territorial portion of the Stuart Highway. Click here see more rules.
