GM announces hybrid bus program in China

Shanghai, China – In conjunction with its participation in the Michelin Challenge Bibendum, General Motors China announced the first joint hybrid bus program with Shanghai Automotive Industry Corporation Group (SAIC) for the China market.

“The launch of our new hybrid bus program and our participation in the
Challenge Bibendum demonstrate that GM is not just focusing on today’s market
but helping drive the development of a sustainable automotive industry in
China through mutually beneficial partnerships,” said Phil Murtaugh, Chairman
and CEO of the General Motors China Group.

The joint hybrid bus program will utilize a hybrid powertrain developed
by GM’s Allison Transmission Division that uses dual electric motors to launch
the bus from a stop and regenerative braking to capture energy in an advanced
battery system. It will be packaged in a bus manufactured by Sunwin, SAIC’s
bus joint venture in Shanghai.

The hybrid technology is already being used to power public buses in
several American cities including Seattle, Philadelphia, Minneapolis and
Portland. It has demonstrated the capability to yield as much as 60 percent
better fuel economy and reduce certain emissions by up to 90 percent. Because
of the unique configuration of its hybrid electric drive, the bus will
generate less noise, require less brake maintenance and produce less engine

GM and SAIC will jointly produce one hybrid bus for commercial evaluation
in the primary stage of the program. The partners will then leverage real-
world in-use data to study the feasibility of mass-producing the hybrid bus
for Shanghai and China.

There are currently about 17,000 buses in operation in Shanghai. Each
runs an average of 155 miles (250 kilometers) per day. A 30 percent
improvement in fuel economy could result in savings of 12 tons of fuel per
vehicle per year.
