Mack Trucks has unveiled its 2017 11-liter MP7 and 13-liter MP8 engines with a handful of advancements designed to simplify maintenance and improve efficiency and productivity.
John Walsh, vice president global marketing and brand strategy for Mack Trucks, says Mack’s new generation engines boost fuel efficiency from 2.1 to 8.8 percent compared with prior model year engines with additional upgrades in power and productivity, while reducing greenhouse gas emissions.
“We have become a leader in innovation,” adds Dennis Slagle, president of Mack Trucks. “We’ve got the best products [now] that we’ve ever made.”
“The product looks amazing,” says Jonathan Randall, Mack’s senior vice president of of sales. “Even the components look amazing, but they perform even better.”
Both engines feature an updated wave piston design that Mack says raises the compression ratio and enables more complete combustion of fuel and a common-rail fuel system that more precisely injects fuel and reduces soot.
“With the pressurized system [and wave piston design], you have much more control and better combustion,” says Stu Russoli, Mack highway and powertrain products marketing manager.
Combined with a two-speed coolant pump, Russoli says these features help increase MP7 fuel efficiency by up to 5.1 percent and MP8 fuel efficiency by up to 5 percent.
