The Toyota Mirai excelled during its 100,000-km road test

While many automakers are concentrating on releasing all the crossovers or taking the EV market by storm, Toyota has been busy promoting its first-ever mass-produced hydrogen fuel-cell vehicle, the Mirai. Hydrogen-powered cars are still in their infancy, thanks largely to a lack of infrastructure, but if and when they become more widespread, Toyota wants to be at the center of it all. In this light, the Japanese automaker just finished a brutal 100,000-km road test of the Mirai in Germany, and the sedan came out looking pretty darn good.

The mega road test was carried out on Toyota’s behalf by KJ Tech Services—a German company whose sole purpose is to drive cars thousands of kilometers to see how they fare. Prior to the test, Toyota met with the firm to discuss the required distance and various terrains and conditions the test should cover. With this information, KJ Tech Services devised a route in and around the Hamburg area and began work.

The Mirai was driven for a total of 16 hours each day, six days per week. A total of eight drivers worked in two eight-hour shifts per day, following the predetermined route on autobahns, city streets, and rural roads for a total of 107 days. At the conclusion of the test, the Mirai had reached a whopping 100,000 kilometers.

But how did the Mirai fare overall? KJ Tech Services project manager Patrick Hake reported that the “Mirai performed excellently with no mechanical breakdowns. The fuel cell operated with 100 percent reliability. This was also the case during a week in which the outside temperature dropped to -20 degrees Centigrade (-4 degrees Fahrenheit), when no problems with cold starts were reported.”

In addition to its reliability, drivers reported that the Mirai was extremely comfortable and spacious—an especially important trait when covering multiple hours at a time behind the wheel. Additionally, testers described the Mirai as easy to maneuver and good at handling curves, with responsive steering and smooth acceleration. Two tire changes and one front brake pad replacement were the only required maintenance over these 100,000 kilometers.

In all, the Mirai was refueled more than 400 times with over 2,205 pounds of hydrogen used. Drivers touted the car’s three-minute refueling time as a definite advantage over traditional EVs, which typically require hours to reach their fully-juiced states.

Currently, the Mirai is available in limited quantities in Japan, California, the UK, Denmark, Germany, and Belgium, though Toyota will add Sweden and Norway to that list this summer.
