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.
