The 2009 Saturn Aura Hybrid gets average gas mileage for a regular car. For stop and go driving in the city, the Aura Hybrid gets a low 26 miles per gallon. For highway driving the car averages 34 miles per gallon. These are not great numbers considering the car is a Hybrid. While most cars in this class are two-mode hybrids, meaning they can power the car without the engine for up to 35 miles per hour, the Aura Hybrid’s electric motor can only power the Saturn up to 3 miles per hour. This cuts deeply into the fuel economy expected of a Hybrid.
