ALLENTOWN, Pennsylvania—There is a distinct sense of history when you walk into the Mack Experience Center here. Originally constructed in 1975 as a research and development facility, it has been the birthplace of modern manufacturing triumphs by one of America’s oldest and most iconic brands. Today, it serves as the 126-year-old OEM’s customer experience hub, celebrating Mack Trucks’ rich history while focusing on its powerful future.

Part of that future is Mack’s reinforced focus on on-highway trucking. Until recently, the legacy Mack Anthem acted as the brand’s versatile tractor for both regional and long-haul fleets. However, with its 117-inch bumper-to-back-of-cab (BBC) length, the legacy Anthem functioned primarily as a short BBC regional truck, pulled into double duty on U.S. highways. 

Last year, as the OEM turned 125, Mack told its customers they didn’t have to compromise. It launched the all-new Mack Pioneer long-haul tractor and a revamped Anthem model to solidify the Bulldog’s place in the crowded North American Class 8 segment. 

Mack tractors head-to-head: Fuel vs. maneuverability 

The Pioner and the new Anthem share identical DNA: the same frame rail options, interior trim choices, and underlying uptime structures. When you step into the cab, you immediately notice the increased width compared to previous legacy models, along with premium amenities and rugged controls. 

The critical difference lies in the BBC spacing, creating two purpose-built tools designed to eliminate fleet compromise:

“If you want maximum fuel efficiency, the Pioneer is the answer,” Blake Routh, Mack’s senior highway product manager, explained during our visit. “If you want maximum maneuverability, the Anthem is the answer. The Pioneer, with its longer nose ... is going to be a little bit more fuel efficient because of the aerodynamics.” 

By shaving 12 inches off the BBC compared to the Pioneer (and 4 inches off the legacy Anthem), the new Anthem excels on tight, urban delivery routes. Its sloped hood increases visibility, allowing drivers to see 12 feet closer to the front bumper. For bulk liquid haulers or LTL operations backing into narrow city docks, that footprint change can be the difference between a clean shift and a costly front-corner collision. 

I asked Routh how mixed fleets are responding to this sudden expansion of choice. He noted that having two separate arrows in the quiver is opening up new territory for both Mack and its customers. 

“We have a lot of customers where they had an Anthem—that’s all we had—and they might be going to the Pioneer because they want to prioritize getting a little bit better fuel efficiencies, or they want a 76-inch sleeper,” Routh told us. “But some of their fleet within the same customer might be more inside the city, so they want to have the shorter nose and prioritize maneuverability. We are actually seeing customers running both to maximize their applications.” 

Behind the wheel of the Anthem day cab

After the highway drive experience, we visited Mack’s test track to get a taste of how the redesigned Anthem handles. 

Adjusting the steering wheel is handled via a single floor-mounted kick-panel lever that controls both tilt and telescoping. Dropping into gear via the column-mounted mDrive automated manual transmission stalk is completely seamless. Moving the gear selector off the secondary dash panel onto the column means you never take your eyes off the pavement. 

The Anthem track experience quickly proved that Mack has addressed cab roll stability. On tight turns, the cab tracks incredibly flat. When taking the Anthem over simulated, deeply rutted Lehigh cobblestones, the redesigned cab suspension elegantly isolated the vertical shock. 

On a 20% incline grade, we tested the Grade Gripper system. Letting my foot completely off the service brake, the truck held dead-still on the steep slope. The electronic brain will safely hold the truck for up to 2 minutes and 45 seconds before automatically applying the parking brakes if it senses driver inactivity.

We also engaged Low-Speed Modulation, a specialized low-speed cruise control adjusted via thumb toggles on the steering wheel. For bulk liquid fleets hauling unbaffled tankers, this tool eliminates the violent, rhythmic “trailer slosh” that occurs during stop-and-go traffic. The engine precisely modulates throttle inputs to keep the load steady, protecting the truck from being jerked forward into a leading vehicle. 

Pushing the guardrails of proprietary active safety

The definitive highlight of the track run was putting our absolute trust in Mack Protect, the OEM’s new proprietary collision mitigation system, replacing third-party technology on past models.

Routh emphasized that bringing active safety software completely in-house was a watershed moment for the OEM. 

“When you want to change something that you don’t design on your truck, it’s always harder,” Routh noted during our roundtable discussion. “When you actually design it yourself, it’s integrated in the truck... and you can dictate what features you want to release without having to wait for a vendor. Functionally, the feedback we’ve heard from customers is that our system walks a really good line of being helpful without being annoying or too in-your-face.” 

Beyond integration, the proprietary shift allowed Mack to implement a standard forward heads-up alert, active lane-keeping assist, and a newly added driver-side blind-spot radar to complement the passenger-side array. 

To test it, we accelerated the Anthem to 20 mph, locked the cruise control, and targeted a stationary target vehicle dummy placed directly in the center of our lane. 

“Just don’t touch anything,” my passenger instructor warned as the dummy loomed large through the windshield. “It’s going to wait till the last second.” 

The truck’s radar and forward camera array calculated our closing rate, fired an aggressive audible warning, automatically activated the hazards to alert traffic behind us, and slammed on the brakes. The stopping sequence is violent but highly effective, bringing 16,000 lb. of bobtail steel to a dead stop exactly three feet from the target’s rear bumper. 

The fleet verdict: Mack Pioneer or Mack Anthem

With 2026 order boards already full, Mack’s dual-truck highway strategy appears to be working. The market response highlights a gapless portfolio that addresses distinct pain points across fleets. 

Carriers running high-mileage, over-the-road freight can leverage the Pioneer to achieve an 11% aerodynamic efficiency gain while retaining premium options such as the factory-integrated Parking Cooler APU and the massive 76-inch high-roof sleeper. Meanwhile, weight-conscious bulk haulers, regional freight, and LTL carriers can spec the shorter, steel-bumpered Anthem to maximize payload visibility and city maneuverability without giving up a premium wide-cab interior. 

By stepping up to an entirely in-house safety platform and engineering their new environment from the driver’s seat outward, Mack has successfully modernized their highway lineup. They haven’t just built a new set of trucks; they have built precision tools tailored to the reality of 21st-century fleet economics.
