Oldsmobile's near-luxury Aurora was redesigned for a spring 2000 debut, as a 2001 model. In the fall, Oldsmobile's flagship gained a standard automatic load leveling suspension. GM's OnStar system became standard on all Auroras in fall 2000. Smaller than the 1995-99 first-generation design in most dimensions, the 21st century Aurora shared its basic platform with the Buick LeSabre and Pontiac Bonneville. Both V6 and V8 engines were offered. The only transmission was a four-speed automatic. Certain rivals, such as the Lincoln LS and Acura TL, offered a five-speed automatic. Seating five, the Aurora had standard front side airbags, antilock four-wheel disc brakes, automatic climate control, leather upholstery, and wood interior trim. The V8 versions rode 17-inch wheels, in place of the V6's 16-inchers, and included traction control and Oldsmobile's antiskid Precision Control System. Both of those systems were optional with V6 sedans.
