The Aura uses the same platform as the Pontiac G6. The XE model has a coarse 3.5-liter V6 paired with a four-speed automatic. A smoother, stronger 252-hp, 3.6-liter V6 with a six-speed automatic is in the up-level XR. Both returned 20 mpg overall in our testing. Our tested XE had a better ride than the XR, which is stiffer and harsh over bumps. Both were nimble and responsive, but easily slid their tails at their handling limits. The interior has considerably nicer materials than past Saturns. Curtain air bags and ABS are standard, but ESC is standard only on the XR and the hybrid version. 2009 was its last year.
