Abstract

Calibration tests and road tests made with a car with a gas-electric drive are described. Runs have been made on concrete, treated gravel, untreated gravel, and wet muddy roads. Curves have been plotted to show gas consumption, power requirements and tractive resistance on these surfaces at speeds up to sixty miles per hour. During the course of these researches, several interesting discoveries have been made as to the effect of speed on tire diameters and the effect of tire inflation on power requirements.
