The Aura Green Line was a mild hybrid, following the Vue Green Line as the second vehicle in Saturn's lineup incorporating GM's belt alternator starter system.
 It rode on the XE's suspension.
It was sold from late March 2007 to 2010.

As in the Vue, the Aura Green Line was equipped with the 2.4L Ecotec engine mated to an electric motor/generator and the 4T45-E four-speed automatic transmission.
The powertrain was rated at 164 hp (122 kW) and 159 lb⋅ft (216 N⋅m) of torque.
The electric motor/generator augmented the gasoline engine during launch and under wide-open throttle.
The Aura Green Line had an EPA estimated fuel economy of 26 mpg‑US (9.0 L/100 km; 31 mpg‑imp) city and 34 mpg‑US (6.9 L/100 km; 41 mpg‑imp) highway (for the 2007-08 model years it was 28 mpg‑US (8.4 L/100 km; 34 mpg‑imp) city and 36 mpg‑US (6.5 L/100 km; 43 mpg‑imp)), which Saturn claimed was up to a 30% improvement over the Aura XE.

The Saturn Aura Green Line was eligible for a $1300 US Federal tax credit, as well as several state tax credits.

Prior to the shutdown of Saturn, General Motors said that they would introduce a new hybrid system in summer 2010.
