2027 Mack AN64T

Category, Truck (conventional daycab, tandem). Zero-mile, new build spec points to fleet-style regional and terminal work, where short dwell times and frequent stops matter more than sleeper amenities. GVWR at 52,500 with 12,500 front and 40,000 rears sets it up for legal-weight highway freight and distribution, not heavy-haul. Powertrain, Mack MP13 rated at 515 hp paired with a 12-speed mDRIVE overdrive and 3.08 ratio, leans toward low-RPM cruise and fuel-conscious linehaul or fast regional lanes. Gear and ratio combination favors staying in the torque band at highway speeds, while still giving enough steps for traffic and grade changes, assuming the intended duty cycle is not start-stop vocational. Running gear, 40k rears on Mack Maxlite air (standard height 51 bogie) supports stable ride quality and consistent fifth wheel height management for van and reefer work. Drum brakes are straightforward service items with predictable wear inspection points, check for even lining wear, cam travel, and heat checking during first PMs. Chassis and cab, 191-inch wheelbase keeps the footprint manageable for docks and yard turns while maintaining tandem stability. Day cab layout means cab storage and driver comfort are focused on daily routes, inspect seat tracks, pedal feel, and switchgear function at delivery, and verify build data against the serial and stock numbers for warranty start and spec compliance.
