The 2024 X12 is focused on improved reliability, lower maintenance cost, better performance, while meeting more stringent EPA Greenhouse Gas standards. At just 2050 pounds, it has the highest power-to-weight ratio of any heavy-duty engine from 10 liters to 16 liters in size. The combination of power and efficiency is striking. With the response and power of larger displacement engines, the X12 delivers the performance drivers desire while maximizing efficiency for every job.

A legacy of proven performance goes into every Cummins X12. From L10 and M11 in the 1980s to ISM and ISX engines through the turn of the century, we’ve been building on a proven platform designed for maximum uptime and productivity. The X12 is manufactured in Jamestown, N.Y., in the same production facility as the Cummins X15,™ and shares many heavy-duty components, including our proprietary Cummins Holset VGT® Turbo, XPI fuel system, Electronic Control Module (ECM), Single Module™ aftertreatment system and integrated powertrain features. It’s an engine platform that’s been tested in the toughest, most challenging operations around the world – from the outback of Australia to the Rockies of Colorado, it just keeps rolling.
