An experimental urban car was designed and built by Western Washington State College as an entry in the international Urban Vehicle Design Competition. The car was designed with a novel form of mid-engine rear drive chassis.
A novel (pyramid link) rear suspension solves many problems. Extreme Ackerman steering allows a 9 ft turning radius. New systems were developed for adjustable pedals, steering, and seat squab height. The chassis quick-disconnects into three major sections to facilitate servicing. A bias beam brake linkage allows easy adjustment of front-rear brake bias.
The low emission engine runs on propane and is equipped with a thermal reactor and an EGR system. The body chassis center unit is made from epoxy fiberglass surface aluminum honeycomb.
Passive restraint seat belts are attached to semigull wing doors. Five mph bumpers are fitted to each end. The front uses extrusion bolts and the spare tire; the rear uses beverage cans in compression.
A headrest window provides whiplash protection while the Ensolite foam-covered dash protects against impact.
