2013 ISL9 and ISB6.7
Better. Where It Counts.

From dotted white lines to double yellow lines, business seems to be filled with lines. But there’s only one that really counts: your bottom line. And being better on the bottom line is what makes Cummins the most popular engines in medium-duty trucks throughout North America.

Better Fuel Economy.
Cummins is boosting the industry-leading fuel economy of our ISL9 and ISB6.7 engines up to 2% in 2013. How? The addition of an air intake throttle makes our Exhaust Gas Recirculation (EGR) more efficient. The VGT™ Turbocharger on the ISL9 has been modified for greater efficiency. The result is a reduction in parasitic losses that increases fuel economy and lowers operating costs.

Better Reliability And Durability.
Cummins designs, develops and supports every critical component from air handling to exhaust aftertreatment as a totally integrated system. This allows us to optimize every function better than any other engine manufacturer.

The ISL9 and ISB6.7 meet 2014 Environmental Protection Agency (EPA) and United States Department of Transportation (DOT) regulations for fuel economy and greenhouse gas reduction a year ahead of schedule without major hardware changes. This means you can expect the same proven reliability and durability you’ve come to expect from Cummins MidRange engines. On-Board Diagnostics are added in 2013, using a system already proven in thousands of on-road vehicles since 2007.

Better Customer Support.
Cummins engines come with a comprehensive base warranty, and multiple options for extended coverage. And they are backed by the largest and most capable parts and service network in North America, with over 3,500 locations.
