Dynamic performance of IZA, developed by TEPCO (Tokyo Elect. Power Co.) has been investigated by using on-board monitoring system since it got car license number in 1992. Observed data have been analysed in detail by comparing with simulation results in order to evaluate and verify realized dynamic performance of the vehicle. The dynamic performance of IZA, maximum speed and acceleration, was first measured at a test course, and then energy efficiency and ranges per one charge for various driving patterns were measured on a dynamometer just after its completion. Then, dynamic performance on highways or in city roads are continuously evaluated. Finally, last year, authors tried a running test on a mountain roads for evaluation of motor temperature as well as regenerating capacity at the severe condition. Through these performance evaluation analysis, the accuracy and validity of the simulation analysis with the model are also evaluated and verified. By those evaluation, it is verified that IZA realized expected performance well within 10 % of specified value. In the paper, results of evaluation methods, procedures and obtained conclusion are summarized.
