Summary:

Fuel economy, performance and driveability are three important subjects for evaluating vehicle performance. Evaluations in both simulations and real vehicles prefer objective and quantitative measures. Subjective and descriptive metrics cannot be easily implemented in simulations, and these evaluations vary with changing time or evaluators. Fuel economy is usually estimated under various city, highway and some other user-defined driving cycles. Performance criteria consist of acceleration/deceleration performance, gradeability and towing capability. Driveability measures deal with pedal responsiveness, operating smoothness and driving comfort. This includes interior noise level, jerk and acceleration parameters. Numerical references and some interpretations of the above metrics are presented in this paper, as well as how these metrics can be used to evaluate vehicle powertrain design and control strategy development
