LOUISVILLE, Ky — Mack Trucks, Inc. unveiled an assortment of product enhancements, including new, optimized roof and chassis fairings for the MACK Pinnacle models, additional fuel-efficient Econodyne ratings for its Mack MP engines and interior enhancements to improve driver comfort and productivity. 

Mack rolled out redesigned roof fairings for its Pinnacle 70-inch high-rise, 70-inch mid-rise and 60-inch mid-rise sleepers.  The company also debuted stronger, lighter, longer chassis fairings, covering up to a 140 gallon fuel tank – yet costing considerably less than the previous option. Customers ordering Mack Pinnacle model sleepers with improved aerodynamics can expect up to a six percent fuel efficiency improvement, according to Jerry Warmkessel, marketing manager, highway products said. 

“The new roof fairings are optimized for the lowest possible coefficient of drag and a much smoother transfer of air from the truck to the trailer,” Warmkessel said. “The design of the new chassis fairings is simpler, and more aerodynamic. The fuel efficiency improvements achievable with these optimized aero aids and the proven performance of our MP engines with ClearTech SCR positions the Mack Pinnacle among the best in highway fuel efficiency.” 

 Warmkessel placed the fuel savings possible by this combination of features at 12.5%  and said he believes such savings at a time when fleets are so concerned about rising diesel prices will lead to greater interest in the Mack brand. 

“We will be in double digit figures in market share in the very near future. I absolutely guarantee it,” he said. 

 Building on the fuel saving performance of its EPA 2010 certified MP engines, Mack also announced the addition of four new Econodyne ratings – MP7-405E, MP8-415E, MP8-445E, MP8-505E –optimized for fuel efficiency without sacrificing power. Through an enhanced fuel mapping strategy, Mack’s EconoBoost intelligent torque management system offers an extra 200 lb-ft. of torque seamlessly through the system command. 

 “We found that drivers can significantly increase fuel efficiency by remaining in the top gear as much as possible,” said David McKenna, Mack director of powertrain sales and marketing. “EconoBoost initiates at 1300 RPM, providing additional power that allows drivers to remain longer in the top two gears. The engine torque reverts back to the lower profile when the engine senses situations with zero torque input, such as cresting a hill.” 

 Further enhancements to the Mack Pinnacle series include an optional one-piece windshield, and an updated Grand Touring trim package with button-tuck vinyl and ultraleather seats that provides drivers comfort and a welcoming environment, at no extra charge over the previous trim offering.  

Mack also introduced a new twin-steer package for its Granite model heavy duty Class 8 conventional straight truck. Available in axle-forward or axle-back packages, the twin-steer now offers vertical back-of-cab aftertreatment – DPF and SCR. Mack’s vocational trucks now also feature Body Link III. Designed with extensive input from body builders, the new Body Link III provides a conveniently located under-cab 29 pin connector, cab pass-through boot for a quick and reliable body hookup, and assignable in-cab switches.
