Mack Trucks first electric refuse truck highlighted at WasteExpo 2021

The Mack LR Electric
Attendees of WasteExpo 2021 experienced the Mack LR Electric, Mack’s first refuse model with a fully electric integrated Mack drivetrain, firsthand, during a ride-and-drive at the show, June 28-30 at the Las Vegas Convention Center.

The Mack LR Electric, Mack's first refuse model with a fully electric integrated Mack drivetrain, was on display at this year's WasteExpo. 

The vehicle features twin electric motors with a combined output of 448  continuous horsepower. The powertrain delivers 4,051 lb.-ft. of torque available from zero RPM, which is fed through a two-speed Mack Powershift transmission to Mack's proprietary S462R 46,000-pound rear axles. 

Four NMC (Nickle Manganese Cobalt  Oxide) lithium-ion batteries, charged through a 150kW, SAE J1772-compliant charging system, offer vehicle propulsion and power for all onboard accessories, driven through  12V, 24V and 600V circuits.

The three-mode regenerative braking system accounts for the refuse truck's increasing load throughout the day and helps recapture energy from the hundreds of stops the vehicle makes each day.

The Mack LR battery electric vehicle was introduced as a prototype at  WasteExpo 2018. Mack delivered demonstrator pre-production Mack LR Electric vehicles in 2020 to the New York City Department of Sanitation (DSNY), the world's largest sanitation department, and Republic Services, an industry leader in U.S.  recycling and non-hazardous solid waste disposal, which is testing the LR Electric model on a residential collection route in Hickory, North Carolina.

According to Mack, the LR Electric may be fitted with equipment bodies from a number of manufacturers, allowing the truck to be tailored to each customer's unique needs. Customers will also be able to choose from the same driver/passenger side driving configurations, seating choices and door options offered on the diesel-powered LR.
