START Bus and Proterra unveiled the community’s first of eight Proterra ZX5 battery-electric transit buses. They are the first battery-electric buses in Wyoming and first Proterra ZX5 buses to be deployed in the United States.
START selected the 40-foot Proterra ZX5 MAX battery-electric transit bus with 660 kWh of onboard energy and the DuoPower™ drivetrain.
Just available in September, the Proterra ZX5 MAX can deliver up to 329 miles of drive range, which represents the most energy storage and longest drive range of any 40-foot electric bus available in the market today.
The DuoPower drivetrain delivers nearly twice the horsepower and five times better fuel efficiency than a standard diesel engine. It features two electric motors that deliver an impressive 550 horsepower, accelerating a ZX5 bus from 0 to 20 mph in under six seconds.
In addition, the DuoPower can propel a bus up a 25% grade, making it an ideal option for routes with steep hills. By combining this drivetrain with Proterra’s industry-leading battery technology and lightweight composite bus body, this vehicle provides superior performance and is designed to tackle Jackson’s routes and winter climate.
START utilized Proterra’s battery lease program to help lower the upfront price of their buses and ensure funding to deploy eight at once, representing one-third of START’s total fleet.
Darren Brugmann START Director notes, “START Bus and the Town of Jackson are thrilled to add battery-electric buses to our fleet. These buses will provide cost effective, clean, efficient transportation, and help START reduce emissions to improve air quality. START is committed to transitioning 40% of its fleet to electric by 2022 and deploying these first eight buses is a major step toward that goal.”
“Proterra is excited to partner with START to bring the first battery-electric transit buses to Wyoming and deliver clean, quiet transportation to local riders,” said John Walsh, Proterra’s Senior Vice President.
Manufactured in the United States, Proterra electric buses feature zero tailpipe emissions, saving approximately 230,000 pounds of greenhouse gases annually when replacing diesel buses. The purpose-built electric buses further offer a quieter ride for reduced noise pollution, greater efficiency, and lower operating costs than combustion engine vehicles.
