Abstract:
"Eight 3-wheel passenger
vehicles of both one-front and one-rear wheel configurations were tested and
compared to similar-sized 4-wheel vehicles. The tests produced measures of
overturn resistance, oversteer/understeer, transient responses to control and
external disturbance inputs, and braking performance and stability. A
comparison was also made of a 4- to 3-wheel conversion, and the effects of
various handling modifications were evaluated. The results indicate that a
properly engineered 3-wheel car can be made as stable as a properly engineered
4-wheel car, although the single front wheel configuration may be less stable in
limit maneuvers."
At the end it indicates a 1F2R Trike may be 'less stable', but some designs of our 2F1R Trikes actually have the capability to be more stable than 4 wheels.
