Uptime

The 2020 X15 Efficiency Series incorporated key product improvements to meet the 2021 emissions standards. Cummins measures the performance of product launches through metrics like “percent zero touch” and “touches per thousand” in order to quantify product reliability and uptime. The 2020 product launch was the best performing product launch to date, and with minimal changes for the 2021 launch, we expect he trend to continue.
Cummins offers the longest service intervals in the industry – keeping you on the road and out of the service bay.
