NYC study of actual fuel economy of fleet finds hybrids more fuel efficient as compared to conventional vehicles than expected

Green Car Congress

Using telematics, NYC Fleet, part of New York City’s Department of Citywide Administrative Services (DCAS), recently analyzed actual fuel economy in its hybrid and non-hybrid vehicles and compared it to the EPA ratings for each make and model. The results showed that hybrids performed better against their EPA ratings than non-hybrids—i.e., hybrids are even more fuel efficient as compared to regular fuel vehicles than expected.
