AS a basis for the analyses of this symposium, a hypothetical car has been used to evaluate the engine power distribution in performance.
Effects of fuel,-engine accessories, and certain car accessories are evaluated. The role of the transmission in making engine power useful at normal car speeds is also discussed.
Variables encountered in wind and rolling resistance determinations are reevaluated by improved test techniques.
Net horsepower of the car in terms of acceleration, passing ability and grade capability are also summarized.
