On sale in the spring of 1994 as an early '95 model, Oldsmobile's new luxury sedan was built on a new front-drive chassis shared with the Buick Riviera coupe. Oldsmobile essentially created the Aurora from scratch, borrowing no parts from other models except the audio systems. Aurora's only engine was a 250-horsepower 4.0-liter V8 with dual-overhead camshafts. It teamed with an electronically controlled 4-speed automatic transmission that incorporated Performance and Normal shift modes. Only a single model was offered. Standard equipment included dual airbags, antilock 4-wheel disc brakes, and traction control with an on/off switch.
