GM at Challenge Bibendum (copyright image)

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.

Chevrolet Volt

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 future.
