The new Mack Pioneer highway truck is now rolling off the assembly line at the company’s Lehigh Valley Operations (LVO) plant in Macungie, Penn.
The facility has been updated to produce the Pioneer alongside other Mack models. Upgrades have been underway since 2017 in preparation for the launch, which took place this April.

“Starting production of the Pioneer at our Lehigh Valley facility is a proud moment for our entire team,” said Stephen Roy, president, Mack Trucks. “Our skilled workforce has embraced the advanced manufacturing processes required for this next-generation truck, ensuring every Pioneer that rolls off the line meets Mack’s legendary standards for quality and durability.”
Mack aficionado Jamie Hagen, owner of Hell Bent Xpress, is among the first to receive a Mack Pioneer.
“The time I spent in the Pioneer left me with quite an impression,” he said. “I love the truck from top to bottom, inside and out. The level of efficiency and comfort this new truck brings sets a standard others will only hope to achieve. I can’t wait to have our entire fleet moving freight with happier drivers and more money to the bottom line. Once you’ve driven one, you will never want to go back to anything else.”
Mack is touting an 11% fuel economy improvement over previous models, enhanced safety systems, and a new, more luxurious 76-inch FlexSuite sleeper.
“Our manufacturing team has worked diligently to ensure a smooth production launch,” said Jonathan Randall, president of Mack Trucks North America. “The enthusiasm we’re seeing from customers like Hell Bent Xpress validates our investment in this groundbreaking vehicle and our commitment to advancing the long-haul trucking industry.”
