Heavily Laden 40-Footer Averaged 325 Miles per Day

Battery bus manufacturer Proterra has released the results of a 106-day trial of a 40-foot Catalyst FC (fast-charge) bus with King County Metro in Seattle. The vehicle ran 24 hours per day to simulate one year and, with 14,500 pounds of water ballast representing 125% of a normal full load of 77 passengers, logged 32,545 total miles – “nearly twice the distance of standard industry tests at Altoona,” Proterra says. updated April 4

The Proterra Catalyst FC bus was charged more than 1,750 times during the 106-day King County Seattle trial.

“From mid-October to the end of January 2016, the bus achieved 98% uptime,” Proterra says. Average fuel economy was reported at 15 MPGe over the test period, 213% better than King County’s current 40-foot diesels, a figure projected to improve to 18 MPGe at normal loads.

Far Cheaper to Maintain

Total estimated maintenance cost, including parts and labor, was approximately 20¢ per mile, Proterra says, citing national fleet averages of 90¢ for diesel buses, $1 for compressed natural gas buses, and $1.10 for diesel-fueled hybrid electrics.

“The performance of this bus was outrageously great,” Proterra field service technician John Wagner, says in a video report. “Tremendous.”

The bus was laden with 14,500 pounds of water ballast, the equivalent of nearly 100 passengers, about 125% of a normal full 77-passenger load.
