Better. 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 from the airport to the hotel or from the local neighborhood to the regional elementary school. We offer three different engines that are widely used for school buses and shuttle buses. Two are clean diesels – the ISB6.7 and the ISL9, which replaces the ISC8.3. The third option is our natural gas Cummins Westport ISL G. All of these engines help you reduce fuel expenses and greenhouse gas (GHG) emissions. The 2013 ISL9 and ISB6.7 get up to 2...

New Standards. Proven Technology. The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Transportation (DOT) have enacted new GHG and fuel-efficiency standards scheduled to take effect in 2014 and 2017. Lowering fuel use results in less carbon dioxide (CO2) emissions, so achieving better fuel economy actually reaches both standards. The fact that Cummins is continuing to use technology proven on commercial vehicles – including currentmodel school bus and shuttle bus engines – is one of the reasons we are meeting these requirements a full year ahead of schedule. Our...
