ISX15 for 2013.  
Better. Where It Counts.

The Best Gets Better.
Cummins ISX15 is the industry leader in just about every type of heavy-duty application from 18-wheelers to fire and emergency vehicles. No other diesel can match it for proven performance with ratings from 455 to 600 hp (339-447 kW) and the highest power density in its class.

Better Means Cummins ISX15.
Cummins ISX15 is designed to deliver better performance, reliability, fuel economy and durability. The ISX15 is easily customizable, including many electronic engine features and adjustable parameters.  Maintenance is virtually unchanged from previous models. Plus, every ISX15 is backed by the largest and most capable customer support network in the business, with Cummins Care representatives available at 1-800-CUMMINS™ to answer product questions and provide assistance during a repair or service event.

For aerials, pumpers and other large fire equipment, you won’t find a better choice than Cummins ISX15.

Better Means Doing It All.
Cummins is the only engine manufacturer to design, develop and support every component from the air intake to the exhaust aftertreatment in a totally integrated system. This allows us to optimize critical systems and deliver performance to emergency responders in a way that other engine manufacturers using outside suppliers can’t match.

Better Means Total Confidence.
In addition to a comprehensive base warranty, Cummins offers a variety of extended coverage plans for up to 10 years/200,000 miles (321,869 km).
