Engineered to be reliable and durable

With Croner we have created a reliable and durable truck, built with proven robust components without compromising on quality. It’s an enduring and easily serviced truck, so you'll spend less time on maintenance and more time making money on the road. Each component is the result of years of development and harsh stress testing to create the ultimate medium-duty platform.

Reliability and durability testing

Croner’s development has been done with quality and reliability at the forefront, right from the start of the design, through engineering, testing and manufacturing. Over 3 years of development and testing by our expert engineers, from initial concept to serial production, who spent 1,700,000 engineering hours, 30,000 hours of testing hours, using 90 test rigs and over 100 test trucks. The result is a vehicle that is ahead of its class in robustness, reliability and durability.

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.

    “This truck, and UD trucks in general, handle the extreme conditions here very well. The weather is extremely hot, yet we never had any issue with the engine over-heating. During the testing, this truck proved very helpful for our business. Croner consumes less fuel and also emits less harmful emissions. Our driver is very happy with the performance of the A/C. Croner is safe, reliable, and always offers a smooth drive – we are definitely planning on buying Croner or similar UD models in the future.”
