Very disappointed with gas mileage. Only 10-15 percent better than non hybrid Saturn. Honda Civic and Toyota Prius hybrids get 40% better gas mileage than non-hybrid Civic. Chevrolet dealer calls Saturn hybrid system the "Half-Hybrid" because it is only belt driven from the heavy duty alternator-generator when the gas engine shuts off at intersection red lights. Will only run 2mph on … battery after stopping, compared to 20mph for Toyota Prius. Saturn Hybrid battery is much smaller. Also, only qualified for one-half the tax credit compared to a Honda Civic hybrid. Also very disappointed in General Motors restricting their dual stage hybrid to their large SUV gas guzzlers and pickup truck
