Safety: Providing a substantial crash/rollover safety cell for the driver is vital. Wings and other aero devices may be of significant help if the racing takes place on a circuit with high speed corners. Intake, Cooling and exhaust need to be considered in relation to chassis design, bodywork and aerodynamics.Īerodynamic: Minimizing the drag created by the bodywork frontal area is important to maximize speed on long high speed runs. Powertrain: Weight distribution is heavily impacted by engine position. The suspension pickup point locations impact the chassis design.Ĭhassis: Providing openings to make internal components accessible for maintenance is important. Springs and dampers (shock absorber) must be matched to the calculated forces. Suspension, wheel and tire weights ( Unsprung weight) affect the compliance of the suspension, which in turn affects handling, so keeping all these components as light as possible is an advantage. Body roll may also be an issue if not properly controlled. Some camber may be of benefit in cornering, but excessive camber will likely mean less traction. Because of the long suspension travel there can be significant camber change.

Suspension: Maximizing the contact patch of the tires with good suspension geometry is of key importance. Left/right weight distribution will usually be 50/50. Weight Distribution: Typically the front will be lighter in front/rear weight distribution due to the rear/mid-engine configuration.
After the iterations are completed, the design will be complete and optimized.īecause of the varied environments where off-road buggies can operate, knowledge of the terrain is important to ensure the vehicle will handle the demands of the surface and speed. Much of the design work is iterative, meaning re-designing areas based on new changes to another area. These six major areas of the car design work as an integrated unit and the designer must have an understanding of how changes to one area affect the others. Superbuggy, Buggy1600, JuniorBuggy (European Autocross), SCORE classes Build Your Own Dune Buggy Knowledge Levelĭue to the scratch-built nature of off-road buggies, you should be knowledgeable in handling, chassis, suspension, powertrain, aerodynamic and safety design.
