Performance
The performance test includes the following:
- Acceleration — Using a large-roll chassis dynamometer, the vehicle is accelerated and the speed verses time data is recorded and plotted.
- Gradeability — From the acceleration data, the gradeability is calculated at 5-mile-per-hour increments.
- Top Speed — The top speed obtained on the dynamometer is recorded. It is noted whether the top speed is power-limited or goverened.
