GM at Challenge Bibendum
USPS delivers mail using a Chevrolet Equinox hydrogen fuel
cell vehicle in Irvine, California (July 2008 image). The U.S. Postal Service is partnering with General
Motors and Chevy's Project Driveway market test to report how fuel cell vehicles operate under demanding
conditions. The USPS will deploy two hydrogen-powered Chevrolet Equinox fuel cell vehicles on regular
routes six days a week in two locations, including Irvine.
30th May, 2010
General Motors will demonstrate its diverse portfolio of
alternative propulsion and advanced mobility technologies today at the Michelin Challenge Bibendum 2010 in
Rio de Janeiro, Brazil. This is the fifth year that GM will participate in the Challenge Bibendum, an
international event that promotes sustainable mobility for the future.
GM speakers will provide updates at Bibendum on several propulsion options that are considered, by GM, to
best meet the varied needs of customers around the world – from highly-efficient internal combustion engines
to electrically-driven vehicles such as hybrids, plug-in hybrids, electric vehicles with extended range and
hydrogen fuel cell vehicles.
Fuel Cell Vehicles
GM continues to evolve its production-intent fuel cell system that could be ready for use in 2015. Though
no production programme has been announced, the new system is half the size, more than 90 kg lighter and uses
one third of the platinum than the system in the current Chevrolet Fuel Cell demonstration fleet.
Motors core to EV Development
Electric motors are the “engines” that transform electric energy provided by a battery or generator into
mechanical energy to drive the wheels of vehicles. GM announced in January that it will build its own
electric motors for some vehicle applications, helping GM gain intricate knowledge on how to make the next
generation of hybrid and electric vehicles even more efficient, thus saving customers money, while at the
same time further reducing the motor vehicle’s perceived impact on the environment.
Later this year in the USA, Chevrolet will make a technological leap in the race to petrol-free driving
with the introduction of the Chevrolet Volt, an electric vehicle with extended-range capability. It debuts
GM’s Voltec electric propulsion technology, which combines a 16 kWh lithium-ion battery, an electric drive
unit and an engine generator. The Chevrolet Volt provides up to 60 kilometres of petrol-free and
emission-free electric driving. Once the Volt’s battery is depleted, the 1.4 litre engine generator provides
power to the electric motors, for hundreds of additional kilometres of extended range.
Vehicle Safety Goes High-Tech
Using cutting-edge wireless communication technology, GM is developing systems that can “see” the traffic
ahead, helping drivers avoid collisions. The system is called vehicle-to-vehicle (V2V) communication and it
uses a simple antenna, computer chip and GPS (Global Positioning System) to communicate with other vehicles
to detect position and movement up to several hundred metres. The system can be used to provide drivers
warnings if vehicles are stopped ahead and also can be used by vehicle navigation systems to alter routes
based on traffic load, reducing commute times and improving road safety.
EN-V: GM’s Vision of Sustainable Mobility in 2030
The rapid population growth predicted for some of the world’s megacities will put a strain on
transportation infrastructure. At the same time, people still will need to travel to their places of work or
for leisure, which is why GM developed the EN-V (Electric Networked-Vehicle) concept. EN-V combines the
benefits of efficient battery-electric propulsion with breakthrough sensing technology that paves the way
toward autonomous driving in a small package that will make personal mobility sustainable into the long-term
