Rugged durability is ensured by the use of proven hardware while continuous improvements have resulted in reliability that provides peace of mind for trucking operations. With the best “Percent Zero Touch” and lowest “Touches Per Thousand” metrics to date, Cummins expects the trend to continue with the 2024 X15 product lineup.

The X15 Efficiency Series for 2024 has demonstrated up to 1% fuel economy improvement for select customers when comparing their powertrain configuration to the 2021 product. With EX ratings providing up to an additional 1.75% fuel economy improvement in certain duty cycles the X15 Efficiency Series continues to help you get the most out of every drop of fuel. And with the longest service intervals in the industry – you’ll spend less money on maintaining your equipment and get more out of it.

Cummins' EPA24 X15 offers a proprietary, prognostic-based maintenance monitoring system that utilizes the expertise and ingenuity of Cummins’ engineering teams combined with the millions of miles of testing data, to deliver life-remaining forecasts on engine consumables including oil, oil filter, stage 2 fuel filter, DPF, and urea filter. This technology utilizes proprietary algorithms, expansive datasets, OilGuard™ insights (where applicable), and virtual sensor data to accurately forecast the appropriate change intervals for filters and oil through an easy-to-understand life remaining prediction.

Features may include:

• Highly reliable and precise design for rapid acceleration

• High pressure enables multiple injection events per cycle for industry-leading fuel economy and quieter operation

• A compact and lightweight system that offers increased ash capacity and extended maintenance intervals

• Superior holding capacity provides better protection and enables longer service intervals

• This allows full integration of data inputs from all subsystems, optimizing performance

• With up to 600 braking horsepower, it’s the most powerful in the industry. Stronger braking capacity reduces wear on service brakes and replacement costs
