Proterra and Freightliner Custom Chassis Corporation (FCCC) announced a collaboration to develop the MT50e, a new all-electric delivery truck chassis. The production-ready MT50e will be on display at the upcoming NTEA Work Truck Show, 4-6 March in Indianapolis.

Built on FCCC’s MT platform, the MT50e will feature a Proterra battery system with 226 kWh of energy capacity and an all-electric drive system. The all-electric chassis can support a GVWR of 16,000 to 23,000 pounds, with no reduction in cargo volume capacity. The vehicle is designed to enable more than 125 miles (201 km) driving range and can fully charge in three hours with SAE J1772 CCS DC fast charging.

The MT-50e is designed to combine the reliability and durability of FCCC’s products with the efficiency and performance of a factory-installed, fully integrated electric power system. Launched as a prototype at the 2019 Work Truck Show, the MT50e is the first planned product in what will be a portfolio of all-electric products for a variety of vocations including pick-up and delivery, baker and linen vocations.
