The X15 is here.

Cummins rolled out the latest generation Heavy Duty engine, the 2017 X15, at its Jamestown Engine Plant in Jamestown, NY on Oct. 1, 2017. The engine is a game-changer in terms of reliability and fuel economy.

The next-generation X15 heavy-duty engines exceed U.S. Environmental Protection Agency (EPA) 2017 greenhouse gas (GHG) and fuel-efficiency standards, with lower fuel consumption, extended service intervals, enhanced performance and the highest quality standards across a 400 to-605 horsepower ratings range. The X15 introduces an innovative approach to duty-cycle optimization, with two configurations, available as the X15 Performance Series and the X15 Efficiency Series. Both configurations are available in limited production through the remainder of 2016 with full production beginning in January, 2017.

“I am proud of the innovative, hard work that has gone into this game-changing engine platform, and we are excited to see these important products rolling off the line,” said Srikanth Padmanabhan, President, Engine Business, Cummins Inc. “Attention to detail was paramount from product design, to our talented colleagues bringing them to life on the manufacturing floor, to every step in between.”

The X15 Performance Series engine, pictured here, is rated at 485 to 605 horsepower and provides an ideal power match for heavy-haul, vocational and emergency vehicles.

The new X15 builds on the current ISX15 product with the implementation of an optimized compression ratio, air handling system and combustion process to increase both fuel efficiency and performance capability. Customers will realize big savings through lower operating costs with up to 20 percent better fuel economy and 40 percent lower maintenance costs than 2010 ISX15 engines.

With the two separate engine platforms in 2017, the Cummins X15 marks a new era in trucking by allowing customers to optimize their engine to best meet their needs without compromise.

“The X15 engines are a sign of what is to come from Cummins. We are firmly focused on understanding the industry trends that are shaping our markets and anticipating the future to develop innovative products and solutions that maximize our customers’ success,” added Padmanabhan.

“A result of this is the X15, which provides customers with improved quality, performance and fuel-economy, while reducing emissions and the environmental footprint. At the core, it’s simple, we win in the marketplace by seeing the future first and beating the competition to it. At Cummins, this is what we mean by innovation you can depend on.”

Every X15 also comes factory-ready to connect to a capable telematics system that enables Over-the-Air (OTA) engine programming, customization, and diagnostics. With Connected Solutions, drivers and fleet managers can manage their vehicle, make quick decisions remotely and even update an engine with the latest calibration without having to bring it to a service bay.

The X15 Performance Series is rated at 485 to 605 horsepower and provides an ideal power match for heavy-haul, vocational and emergency vehicles with a peak torque of up to 2050 lb-ft delivered across a wide engine rpm range, and up to 600 horsepower engine braking at 2100 rpm. For line-haul and regional-haul applications, the X15 Efficiency Series offers an unmatched level of fuel efficiency and payload productivity, with a 400 to 500 horsepower ratings range and up to 1850 lb-ft of peak torque available at 1000 rpm.
