Abstract
A 3-wheeled commuter car (model 511) has been developed to carry two people from home to work at freeway speeds. Many radical design and construction features are employed. The car is small and lightweight, a combination offering high fuel economy, low exhaust mass emissions and some help for the parking problem. The 511 car, in its present form, is still a test vehicle. Although several major problems are unresolved, the car has demonstrated the technical feasibility of its basic concept.
