. . . A simple dashboard displays the vehicle’s functional layout, enabling users to monitor operation levels, see faults and resolve many issues directly through the interface without physically removing bus panels. A virtual mechanic, the Diagnostic Tool provides access to most of the vehicle’s operational features, including monitoring of the overhead charging system. . . .
To ensure safe and comfortable operation in winter conditions, the company is also introducing the Proterra Cold Weather Package . . . since the bus is electric and has no combustion engine, there is no excess heat to reuse within the vehicle. The Cold Weather Package addresses this issue with two different configurations, depending on the severity of climate.
For regions with occasional snow and below-freezing temperatures, the Standard Cold Weather Package offers a front door and ADA ramp diffuser to remove ice and minimize slipping, heated mirrors to ensure better visibility, and a heated charge blade and scoop on the roof of the bus for consistent charging all winter.
In areas with more extreme winter weather, such as northern or mountain climate zones, the Extreme Cold Weather Package offers the features of the Standard Package, with additional auxiliary heat for sub-zero conditions to keep riders and drivers comfortable. In addition, a heated rear exit floor prevents ice buildup. Optional features, including integrated chains and belly pans, add an extra layer of safety and operational reliability.

. . . A $7.5-million grant from the California Air Resources Board (CARB) will support the building of 13 battery-electric school buses as part of the Sacramento Regional Zero-Emission School Bus Deployment Project. The 13 buses will go to Elk Grove Unified School District and Twin Rivers Unified School District. . . .
The new all-electric buses will be powered by Motiv’s all-electric powertrains . . . The buses, Trans Tech’s all-electric eSeries built on the Ford E450 chassis, will be distributed by First Priority GreenFleet. Motiv’s powertrain replaces the diesel or gasoline engine on a standard chassis. . . .
The electric school buses support a battery capacity of 85 or 106 kWh, with a range of 68 to 85 miles. The 150 kW electric motor delivers 1,200 N·m of torque (885 lb-ft). Top speed for the bus is 60 mph. . . .
