GM invests $6 million in electric bus manufacturer Proterra

General Motors Ventures
has announced that it will invest $6 million in Proterra, a manufacturer of battery-electric commercial transit buses. GM Ventures is part of an investment group, led by venture capital firm Kleiner Perkins Caufield & Byers, that will fork over a total of $30 million to Proterra.

Proterra says that its EcoRide BE-35 electric bus is averaging approximately 24 miles per gallon ( diesel equivalent) in real-world use, a claimed 600 percent improvement over a typical diesel-fueled coach. Using technology developed by Proterra, the composite-bodied BE-35 can recharge via its roof-mounted Fast Fill system in about ten minutes and whoosh on down the road for 40 miles before needing another energy dose.

Currently, three EcoRide BE-35 buses are in use near Pomona, CA. This investment will supposedly allow Proterra to complete federal validation testing of for the BE-35 and increase production to 400 units a year at its Greenville, SC manufacturing facility.

GM Ventures Invests in Battery Electric Bus Company

Part of a $30 million package to commercialize technology, including rapid-charging transit system


DETROIT – General Motors Ventures LLC will invest $6 million in Proterra Inc., a leading maker of zero-emission commercial transit buses, as part of its mission to invest in next-generation technologies that support innovation in the global transportation industry.

GM Ventures is part of an investment group, led by venture capital firm Kleiner Perkins Caufield & Byers that will invest a total of $30 million in the bus manufacturer.

Proterra's EcoRide™ BE-35 battery electric bus is averaging up to 24 mpg (diesel equivalent) in service, a more than 600-percent improvement over a typical diesel bus. Using technology developed by Proterra, the lightweight, composite-body bus recharges in about 10 minutes.

"This equity investment further demonstrates GM's commitment to electric propulsion and supports our commitment to identify and invest in technology solutions that help advance the global transportation industry," said Jon Lauckner, president of GM Ventures. "While this investment will help Proterra commercialize its electric bus and fast-charging technology, it also helps to address the future challenges of urban mobility."

Proterra Inc. was founded in 2004 and is currently manufacturing buses in a temporary plant in Greenville, S.C. near Clemson University International Center for Automotive Research. Proterra's TerraVolt™ energy storage system consists of 54-72 kWh lithium titanate battery packs that recharge in 10 minutes using the company's roof-mounted Fast Fill™ recharging system.

Three EcoRide BE-35 buses are currently in a test fleet near Pomona, Calif., with additional buses to be added, and new buses and charging stations are also headed to San Antonio and Tallahassee, Fla., later this year. This investment allows Proterra to complete federal validation testing of its bus, roll out additional pilot fleets and complete initiatives to significantly reduce costs and increase volume production at its Greenville, S.C. manufacturing plant, which will have the capacity to produce 400 buses annually.

With up to a 40-mile range for the under 10-minute fast charge application, the EcoRide BE-35 can easily replace 80 percent of diesel buses in typical transit and shuttle use without altering schedules or passenger service. The EcoRide can also be configured for longer ranges while charging at a central location.

"With the support of GM's automotive expertise and technology leadership, we can achieve a better, cleaner future for public transportation," said Jeff Granato, president of Proterra. "We are proud to have General Motors on board."
