Shifting to Cummins X15™ with the Endurant™ Transmission.

If you have customers that previously spec’d the Cummins ISX12 in their commercial trucking fleet, the best option for 2019 is for them to upgrade their next truck order to a Cummins X15 Efficiency Series engine paired with the Endurant 12-speed automated transmission from Eaton Cummins Automated Transmission Technologies.

The X15+Endurant powertrain is almost identical to comparable ISX12 powertrains in terms of total system weight. At 3,814 lb it is just 31 lb more than a typical ISX12 engine and transmission.

However, the performance benefits are huge, especially for customers that need the pulling power of a big bore engine.

Where the ISX12 maxed out at 425 hp, the X15 Efficiency Series delivers up to 500 hp.

Torque ratings for the ISX12 ranged from 1150 to 1650 lb-ft The X15 starts at 1450 lb-ft and goes all the way up to 1850 lb-ft.

Your customers will be getting an engine that never has to strain, even when hauling 80,000 lb up a 6 percent grade. And fleet managers will never have to worry about drivers missing shifts or using less than efficient driving habits, as the Endurant Automated Transmission helps novices as well as experienced pros perform safely behind the wheel. It’s even geared to make slow-speed maneuvering easier.

Plus, with the lowest cruising rpm among competitive automated transmissions and the best overall ratios, the Endurant is ideally engineered to fully support the growing move to downspeeding, helping your customers save fuel. This, coupled with longer service intervals, can help fleet customers lower their cost of operation while improving driver satisfaction.
