The Aura XR has an EPA rating of 18/26 (give or take). We consistently average 20+ in town and for 252hp, it averaged a respectable 28.5 - 30.3npg on a recent 18hr road trip. Did I mention we were fully loaded (4 humans and a full trunk)! see full Saturn AURA review

Its six cylinder engine could not realistically be compared with a four. I really wanted to consider the Aura GL, and had had a request in to a dealer to let me know when they got one in. I never received a response to the call. see full Saturn AURA review
