A zero-emission bus tours California, Toyota flirts with ethanol, and more green auto news
Thursday in San Francisco, it was easier to get an electric bus than an electric car. Proterra, a commercial hybrid- and electric-vehicle manufacturer in Golden, Colo., finished its weeklong California clean bus tour in the city by the bay. The sleek EcoRide BE35 climbed the hills of San Francisco, flaunting its environmental and fiscal charms before California municipal and transit stakeholders.
Why California? Besides being the ultimate destination for fair-weather roadtrips, the California Air Resources Board mandated that 15 percent of all municipal urban bus fleets purchased for the 2012 model-year and beyond must consist of zero-emission buses.
The EcoRide features an energy storage system that can be charged under 10 minutes as well as a regenerative braking system, which captures over 90 percent of the vehicle’s kinetic energy available while braking.
Proterra claims that a BE35 can result in up to a 400 percent improvement of fuel economy, which the company calculates to be a $310,000 savings in fuel expenses ($3.50 per gallon of diesel) over the lifetime of the vehicle. Sarahjane Sacchetti, a spokesperson for Proterra, declined to state the retail price for an EcoRide, but said that it was competitive with the fuel economy savings.
The most high-profile contract that Proterra has signed to date is the supply of a hydrogen fuel-cell bus to the city of Burbank, Calif.
