Continued from page 32 "We're also going to offer better performance from these next-generation engines," Wenzler says. "Drivers will no- tice improved response to their throttle inputs, along with taller gearing and 'smarter' electronics, which will allow them to drive better by helping manage power demands while still delivering improved fuel economy. " The ISX15 I'm driving is a prototype engine mounted in a 2012 Peterbilt 386 that Cummins keeps at its product evalu- ation lab on the outskirts of Columbus, about an hour south of Indianapolis off Interstate 65. The engine churns out an impressive 450 horsepower while run- ning at 1,750 rpm. Cummins plans three versions of the ISX15 based on torque and horsepower. This test engine – which Cummins calls a Family One – will be introduced for fleets next year. A Family Two version for premium fleet and owner-operator trucks, as well as a 600-hp Family Three variant for heavy haul, will follow soon afterward. To help boost fuel economy, Wenzler www.contitechairsprings.us Aftermarket Air Spring Assemblies Manufactured to OEM Standards says, engineers worked hard to reduce parasitic loads inside the engine design, including a new optimized fuel pump with reduced internal friction, a newly designed variable geometry turbocharger and a new intake throttle design to optimize exhaust gas recirculation flow in the engine. "We're looking at every detail, no matter how small," Wenzler says. "For example, how fast do you need to spin a water pump to maintain cooling ef- ficiency? And how does that affect fuel economy? Nothing is off the table." Cummins also has taken advantage of more powerful electronic engine controls to make drivers' lives more comfort- able during long days behind the wheel. To that end, the new ISX15 will feature multiple new driving tools.
