Abstract: A relatively low-cost, lightweight vehicle has a traction belt drive system, a force-spreading air bag suspension, and operational efficiency features. The traction belt cooperates with track wheel assemblies on each side of the vehicle to spread the suspension forces and to provide efficient steering ability. Each traction belt can be in the form of a Moebius strip. The air bag suspension uses integral air bags on each side of the vehicle cooperative with plural flaps pivotable on a central keel to spread varying suspension forces and to smooth the ride over a variety of terrains. The vehicle lends itself to efficient relatively low cost manufacturing techniques using standard materials.
