Cummins: Next Generation

                There has been a lot of buzz in the trucking world recently. Cummins has announced their new generation of highway engines for 2017 that will replace the current ISX15 engine line. This new X15 line of engines is an evolution of the current ISX 15 engines. This new line boasts improved efficiency, higher horsepower, and higher torque ratings. Cummins has estimated a fuel efficiency increase of up to 20% over the 2010 models, and a 40% decrease in the cost of ownership over the first 500,000 miles.
                Cummins has divided the X15 into two different options. Cummins will offer a performance version and an efficiency version of this engine. The performance option will boast 475-605 horsepower and 1,650-2,050 lbs.-ft of torque. The performance X15 will have an upgraded high-flow air intake system for increased pedal response and improved drivability under heavy loads and steep grade conditions.
                The X15 efficiency series engine will increase fuel economy 3% over the 2016 model and 10%-20% over the 2010 model ISX engines with equal displacement. This engine will have up to 500 horsepower and 1,850 lbs.-ft of torque. The X15 efficiency series engines are also designed to dramatically reduce the cost of ownership. Oil-drain intervals have been extended by up to 80,000 miles through Cummins’ new OilGuard program, and fuel filter intervals have been extended up to as much as 50,000 miles. Cummins’ engineers have designed the crankcase breather filter to be maintenance-free, eliminated the hydrocarbon doser, and made the coolant filter optional.
                Both the X15 Performance and Efficiency series engines have several new features that make this new generation of engines appeal to owners and operators alike. The 2017 models have an overall reduction of the number of components and simplified systems to minimize downtime. Full production is scheduled to take off in January 2017.
