Mack Trucks will showcase its Mack LR Electric, a Mack MD7, and a Mack TerraPro during WasteExpo 2024 next week in Las Vegas, Nevada. Plus, two LR Electric refuse models will be part of the ride-and-drive.

The Class 8 Mack LR Electric

The next generation Class 8 Mack LR Electric refuse model offers a standard 376 kWh total battery capacity for 42% more energy and an increased range between vehicle charges. Twin electric motors produce 448 continuous horsepower and 4,051 lb.-ft. of peak torque output from zero RPM.

Four NMC (nickel manganese cobalt oxide) lithium-ion batteries, charged through a 150 kW, SAE J1772-compliant charging system, power the vehicle and all onboard accessories through 12V, 24V and 600V circuits. The two-stage regenerative braking system helps recapture energy from the hundreds of stops the vehicle makes each day with an increasing load.

Mack LR Electric specs are:

  • Body: Heil Automated Side Loader (ASL)
  • Battery: Four lithium NMC batteries, 376 kWh
  • Front Axle: Mack FXL20, rated up to 20,000 lbs., with Mack Multileaf springs

The Class 7 Mack MD7

The Mack MD7, a Class 7 model with a gross vehicle weight rating (GVWR) of 33,000 pounds, is exempt from the 12% Federal Excise Tax (FET), as is the Mack MD6.

Available in 4x2 configurations, the Mack MD7 is ideal for refuse collection in tight or weight-restricted areas and other applications. The MD model also offers a clear back-of-cab and top-of-frame rail, making it easier for body builder adaptations.

  • Front Axle: Meritor MFS+ 12,000-lb. taperleaf suspension

The Mack TerraPro for Refuse or Concrete

Mack said the TerraPro model is a versatile and powerful truck. The TerraPro model can handle the toughest of applications, whether it’s being utilized as a refuse vehicle or as a concrete pumper.

Mack TerraPro specs are:

  • Body: McNeilus Atlantic Front Loader
  • Engine: Mack MP7 Powerleash, 355 horsepower and 1,260 ft.-lb. torque
