ENGINES. THE RECORD BOOK.
The Cummins ISX15 has been the best-selling engine in its category for years.
Today, when customers purchase the X15, they not only get the legendary
reliability and durability they’ve come to expect, they also get an engine that’s
tailored to their application. The X15 Performance Series offers exceptional
power to go along with class-leading dependability and a lowered total cost of
operation. Ideal for heavy-haul applications and extreme duty-cycles, the X15
Performance Series lives up to its reputation as the king of the heavy-duty class.
MORE POWER. MORE CAPABILITY.
With the change in rating strategy, the X15 provides the broadest torque and
horsepower range of any engine in its class. In 2020, the X15 Performance
Series provides up to 565 hp and 2,050 lb-ft torque. The extra muscle of
15 liters means that the X15 doesn’t have to work as hard pulling the load,
so you’ve got an engine that’s going to use less fuel, last longer and be
worth more at the end of the run. Yeah, going big pays big dividends.
But you already knew that.
X15 PERFORMANCE RATINGS.
With a broad range of performance ratings from 485 hp to 565 hp, there is
an optimized solution to deliver the ideal level of power for your application.
