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.
“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,” Mack highway marketing manager Jerry 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.”
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 – fully 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.
