‘Not a me-too truck’: Inside the Mack Anthem cab The first thing you notice about the Mack Anthem is that Mack’s new Class 8 on-highway offering wears its edge on its sleeve. But the new truck is more than its chiseled lines and bold highlights; it’s been designed from the ground up both inside and out. The Mack Anthem’s aerodynamic enhancements improve fuel efficiency by up to 3% compared to the Mack Pinnacle, and it is available as a Day Cab, a new 48-in. Flat Top Sleeper, and a new 70-in. Stand-Up Sleeper. Come along as we crawl through the Mack Anthem on this episode of On the Road.
