The redesigned 2001 Aurora is available in two sedan models: the 3.5L and the 4.0L. The 3.5L DOHC V6 generates 215 horsepower, and the enhanced 4.0L DOHC V8 produces 250 horsepower. The new Aurora is six inches shorter than its predecessor, yet design changes increase interior space for front and rear passengers. Standard features for the 4.0L model include a Convenience Package, an All-Weather Package, and a Passenger Comfort Package. The Convenience Package includes an automatic day/night mirror with compass, memory controls for outside mirrors and driver seat, a universal garage door opener, and moisture-sensitive wipers. The Convenience Package, All-weather Package, and Passenger Comfort Package are optional on the 3.5L model.
