Ricardo Showcases Hybrid Technology at the 2007 New York International Auto Show

Release date: 04 April 2007

Demand for fuel-efficient and environmentally friendly vehicles is on the rise as the public, governments and vehicle manufacturers look for ways to reduce fuel consumption and greenhouse gas emissions. Ricardo will showcase a cost effective micro hybrid powertrain system in the Taxi ‘07 exposition at the New York International Auto Show. This technology, which could have significant impact on emissions and fuel consumption, is very well suited for taxi and small delivery truck applications

“The hybrid system we are displaying at Taxi ’07 represents an excellent fit for New York’s stop-and-go traffic”, said Jeremy Holt, president of Ricardo US. “Although called a micro hybrid, the benefits can be very significant. Most vehicles can accommodate this system, including taxis. If this technology were applied to all New York City taxis, Ricardo estimates that 10.8 million US gallons (40.9 million litres) of gasoline per year could be saved, reducing greenhouse gas emissions by 105,000 US tons (95,000 tonnes) of CO2 per year.” In Ricardo’s micro hybrid system the standard alternator is replaced by a more efficient electric motor-generator. The system is termed micro because the hybrid system is a small increment to the existing powertrain and represents minimal additional cost. When the vehicle idles in traffic jams and at stoplights, the micro hybrid system shuts the engine down. This reduces fuel consumption while also reducing carbon monoxide, hydrocarbon and nitrous oxide emissions. When the driver moves his or her foot from the brake to the accelerator pedal, the electric motor starts the engine instantly and silently. Also, energy generated during braking can be captured and used to power the vehicle, again contributing to further efficiency gains.

The Taxi ’07 exhibit will be located at the inner roadway of the Jacob K. Javits Convention Center at 11th Avenue and 35th Street in New York City and will be open during the public days of the NYIAS, from Friday, April 6 until Sunday, April 15.
