Mack Trucks is set to showcase four trucks at this year’s WasteExpo, hosted at the Las Vegas Convention Center from May 6-9. Among the vehicles featured are two LR Electric models, Mack’s fully electric Class 8 trucks, which are noted for their significant battery capacity of 376 kWh—a 42% increase in energy storage compared to previous models, enhancing their range. These trucks are equipped with dual electric motors producing a combined 448 horsepower and 4,051 lb-ft of torque, supported by four Nickel Magnesium Cobalt Oxide lithium-ion batteries. They utilize a 150 kW charging system compliant with the SAE J1772 standard and feature complex electrical systems to power all onboard operations and accessories.

In addition to the electric models, Mack will also display the diesel-powered MD7 and TerraPro models. The Class 7 Mack MD7 4×2 features a 300 hp Cummins diesel engine, an Allison six-speed automatic transmission, and both front and rear suspension systems designed to accommodate a gross vehicle weight rating (GVWR) of 33,000 lbs, exempting it from the 12 percent Federal Excise Tax. Meanwhile, the Mack TerraPro is available in configurations suitable for refuse collection or as a concrete pumper, boasting 355 hp and 1,260 lb-ft of torque, supported by robust axle ratings and integrated Mack technology systems for enhanced vehicle monitoring and updates.

The highlight of the expo will likely be the opportunity to test drive the LR Electric, with demonstrations scheduled from 10 a.m. to 2:30 p.m. on May 7 and 8 at the West Hall Diamond Lot. This will provide attendees a close look at Mack’s advancements in electric vehicle technology, particularly in heavy-duty applications.
