Major changes to the Aura line include the discontinuation of the Green Line name, 3.5-liter V6 XE model and four-speed automatic transmission. The upscale XR trim can now be ordered with a 2.4-liter four-cylinder, while Saturn's six-speed automatic transmission with tap shift becomes standard on all models except the Hybrid. StabiliTrak stability control is also made standard, as are redundant audio controls (XE, XR). On the Aura Hybrid, 17-inch alloy wheels with low rolling resistance tires replace 16-inch alloys.
The Aura sedan is the second piece of the puzzle that promises to reveal, within a short couple of years, a completely reinvented Saturn. Like the SKY roadster introduced earlier in 2006, the Aura is more stylish and more confident than anything Saturn produced in its first 15 years of existence. Although the Aura shares a platform with the Pontiac G6, Saturn's version feels significantly more refined inside, outside and on the road. Later, a gas-electric Aura is scheduled to arrive as GM's first hybrid sedan. Even as Saturn begins unleashing its most appealing cars ever, the automaker has committed to maintaining its popular "no haggle" pricing policy.
