So much racing is done primarily in two dimensions… even if the tracks have elevation changes, it isn’t like the racers are having to account for terrain.
Not so with off-road racing. Rally, desert racing, stadium and short course off-road racing. These each have a lot of terrain that needs to be accounted for in the design of the suspension. None more than desert racing. It might be whoops that are two feet deep, or it might be jumps that send the vehicle 20 feet in the air and 100 feet downrange.
Trophy Trucks and Truggies are amazing, with suspension travel at each corner that is about the same as an entire field of F1 cars. These things might allow as much as 24″ of controlled wheel travel on the race course. They will drive through washboard at 100mph and barely jostle the drivers… and fly with ease… and land with ease.
Thanks for watching.
