Catalyst XR Bus ‘Shatters Electric Vehicle Range Perceptions,’ Company Says

Proterra is reporting today that its 40-foot Catalyst XR bus logged 258 miles on a single charge at the Michelin Laurens Proving Grounds in Mountville, S.C. The bus was fitted with eight NMC/nickel manganese cobalt lithium ion battery packs with a total energy capacity of 257 kilowatt-hours.

“Based on these test results, Proterra predicts its ten pack XR configuration (321kWh) will achieve 300 miles on a single charge,” states a release.

The Michelin Laurens result “shatters electric vehicle range perceptions,” Proterra says.

“According to available General Transit Feed Specification (GTFS) data, typical urban and rural bus routes in the United States run less than 200 miles a day, bringing most routes within reach of Proterra’s current technology.”

‘Best Efficiency Rating Ever’

“The purpose-driven Catalyst design affords the best efficiency rating ever for a 40-foot transit bus, at 22 MPG equivalent,” Proterra chief engineer John Sleconich says in the announcement. “Proterra buses are the only mass transit vehicle built from the ground up as an electric vehicle. With a unique aerodynamic body made from carbon fiber and advanced composite materials, we are able to reduce mass for maximum efficiency.”

‘Pushing the Bounds of EV Technology’

“While diesel buses pollute our communities and are increasingly more costly to own and operate, Proterra is pushing the bounds of EV technology and steadily driving down costs,” said CEO Ryan Popple.

“Achieving this range is validation for our technology and gives us the confidence that Proterra is capable of what we initially set out to accomplish – replacing every fossil fuel bus in the United States with a fully electric one. ”

“We’re the first company that took the time, the capital and engineering resources to really figure this out from the ground up as a purpose-built EV,” Popple says in a video about the recent tests.

Proterra said today that it has sold more than 110 vehicles to 14 different transit agencies in North America.
