needed to be looked at closely. Cold-resistance tests were conducted in winter in 1996 and 1997 in Shibetsu and in Canada. In the summer of 1997, the car was shipped to New Zealand for another cold-resistance test on a farm. At the same time, another group installed the THS in a Corona and drove 4,000 kilometers from California to Nevada. Five engineers, including an engine expert, a THS expert, and mechanics, participated in the excursion, and rode in one car. The hardest experience of all was the five-day journey, travelling 3,000 kilometers in the 45degree (Celsius) weather. Fortunately, there were no problems. While the five members felt confident with the car, they also felt disarmed, because they had expected some problems to come up. The battery, the cause of great concern just a few months ago, was finally complete, and Muramatsu was overcome with emotion. More than 100 batteries had been used on test vehicles. Once they were installed in the Prius, the rear seats had to be removed to set the batteries out every time it discharged or had other problems. The batteries, then would be sent back to Panasonic EV Energy for inspection. When Prius is driven for a long time in conditions that causes stress on the battery, a turtle-shaped indicator lights up in the Center Meter gauge that shows battery charge volume. It means that the driver must 325
drive as slowly as a turtle, because the battery is empty and the car is powered by the engine. Muramatsu suggested a silly idea. "Why don't we first have the whole turtle as a warning, and then have a turtle without hands or feet to show that the battery is empty, that the turtle is finished and can't do anything about it?" "Muramatsu-san, this turtle indicator is not a joke. It is the uniform standard for our eco-friendly car. I'm sorry, but we can't do that." The idea was flatly rejected. This time, it was Muramatsu that was finished. 326
