Reliability and Durability Testing

UD Trucks Croner Ozono-san
Months and years of development and testing
Strong endurance has been a UD Trucks trademark since the start of our foundation, which is why our reliability and durability testing programs are so rigorous. And Croner has excelled in all of them.
Durability testing was conducted for an equivalent of 3 million kilometers, putting the Croner to the test in the toughest weather conditions and terrains around the world. In addition, 1.4 million kilometers of field tests in actual customer operations were carried out across 6 countries and 3 continents over a period of 18 months.
