The US giant will be the fourth car manufacturer to put a pollution-busting vehicle on the market. The Chrysler arm of DaimlerChrysler will offer a gas-electric hybrid car in the US in 2003, the company announced on 24 October. The hybrid Dodge Durango, like other planned or available hybrid models, will use an electric motor tied to a battery pack to increase mileage, and cost a few thousand dollars more than a regular version.
