Hydraulic hybrid cars to be mass produced by Chrysler. Using a brake-stored "launch assist" technology developed and tested by the EPA since 2004, the lesser known hydraulic hybrid vehicle is relatively clean-burning and fuel efficient, easy to deliver, and isn't powered by batteries. How it all works.
The Chevy Volt, GM's new plug-in hybrid electric car. For a customer driving about 40 miles a day or about 15,000 miles a year, compared to a 30 mpg car, the Volt would save about 500 gallons of gasoline per year. If the car is charged every night, the driver should be able to achieve that mileage using virtually no gasoline. That same example would also save 4.4 metric tonnes of CO2 every year from each car. All it needs for mass production is a supplier for its untested lithium ion battery concept.
