Cummins bus engines


Better Where It Counts. Every Route.


At Cummins, our goal is to make sure the wheels keep turning – every hour of every day, on every type of route, whether it’s the most demanding urban transit routes or from the airport to the hotel or from the local neighborhood to the regional school.

What counts is cleaner, more fuel efficient and more reliable engines to keep your buses on schedule. That’s what Cummins engines deliver, whether you are looking for diesel, natural gas or diesel electric hybrid engines to power your bus fleet.

Not only do all of our Cummins bus engines meet U.S. Environmental Protection Agency (EPA) 2013 emissions standards, but they also meet 2014 greenhouse gas (GHG) and fuel efficiency standards a full year ahead of schedule. Our ISL9 and ISB6.7 clean diesel engines get up to 2 percent better fuel economy versus 2010 engines, while the Cummins Westport ISL G takes advantage of an abundance of domestically produced natural gas to provide lower total cost of ownership. These engines share common base engine components, for exceptional reliability and durability.
