The 58-inch mid-rise sleeper is well-suited for operators who go out for two or three days at a time and don't need a full-size studio sleeper. Also newly available on the 579 is Paccar's MX-11, which recently was rolled out for sister Paccar company Kenworth. Other options rounding out the Model 579 Epiq enhanced fuel economy spec are a new Predictive Cruise Control System, as well as Eaton and Paccar's jointly developed optimized drivetrain. The sleeper's reduced size doesn't mean it's cramped. It offers plenty of room to stretch out, a standard HD TV mounting bracket, a combination work/storage station, an optional mini- fridge and an array of cli- mate and lighting controls. The MX-11, designed by Paccar's DAF subsidiary in The Netherlands, is being built in Columbus, Miss., for global distribution. Anthony Gansle, Peterbilt's on-high- way marketing manager, says that although the engine was designed primarily with voca- tional applications in mind, technology has advanced so much that drivers for regional- and long-distance line-haul fleets looking to maximize fuel economy should consider spec'ing the Peterbilt adds new sleeper, predictive cruise, 11-liter engine to Epiq spec BY JACK ROBERTS The high-power version of the MX-11 delivers an impressive 430 horsepower.
