Phil Cady, from Nissan, show off the new 2007 Nissan Altima Hybrid  at the Third Street Promenade during the KABC Clean Air Car Showcase on Saturday, June 9, 2007. The new Altima Hybrid gets 42 miles per gallon in the city and 36 MPG on the highway. Unlike gasoline powered cars, hybrids get better gas mileage in the city than on the highway because they manly use batteries in the city and gasoline on the highways.
