EPA invents battery-less hybrid system

The Environmental Protection Agency says it can help drivers save fuel. It has said that for a long time, of course, but this time it’s not talking about providing fuel mileage data for car shoppers. It’s talking about a new invention created in its own Ann Arbor, Mich. research laboratories.

The UPS truck could get as much a 70 percent increase in fuel efficiency in city routes, the EPA estimates, and the added cost of the trucks should be paid off in fuel savings in about 2.5 years.
