MEASUREMENT OF CHEVROLET AVEO CAR MOTION RESISTANCE BY COAST-DOWN METHOD

Abstract

At road coast-down test of Chevrolet Aveo sedan the aerodynamic drag coefficient Cd = 0,367 and the coefficient of rolling resistance  = 0,0143 is defined. The reference values of coast-down are calcu-lated. There have been revealed discrepancies between the real slowdowns and the calculated ones.
