ISX15: Proven Technology Preferred by Fleets

Since its introduction in the late 1990s, Cummins ISX15 has been a market share leader in heavy-duty trucks, with both owner/operators and commercial fleets alike.

The current ISX15 illustrates how advanced planning allows Cummins to deliver a proven product to the market.

This fully integrated package includes engine and aftertreatment components designed and built by Cummins. Total integration allows us to optimize fuel economy, reliability and durability. It also allowed us to meet 2014 greenhouse gas (GHG) and fuel efficiency standards a full year in advance, so the engines that your customers are buying today already have been proven by thousands of customers running millions of miles in real-world applications.

Current ISX15 customers are seeing up to 2 percent better fuel economy over previous models – the result of continuous improvement to reduce parasitic loads. Plus, Cummins and Eaton® have teamed up to offer a SmartAdvantage™ Powertrain that delivers 3 to 6 percent better fuel economy, smooth shifting and torque when your customers need it.

More proven technology on the ISX15 includes the VGT™ Turbocharger from Cummins Turbo Technologies, which continues to set the industry standard for simplicity, efficiency and performance. The standard Intebrake™ feature provides additional braking capacity, for safer operation, and helps service brakes last longer. Oil drain intervals have also been extended by 5,000 miles (8,000 km) when Valvoline™ Premium Blue™ engine oil is used.

When you take the proven technology that is unique to Cummins ISX15, back it with North America’s largest and most capable parts and service network, then add the responsiveness of Cummins Care™ to the package, it’s clear why Cummins ISX15 is offered by so many OEMs – and the engine of choice for so many fleets.
