Rear-drive luxury sport sedan (2005-2011). Northstar V6 or V8, the larger sibling to the CTS.
The Cadillac STS was a rear-drive luxury sport sedan that sat above the CTS, offering Northstar V6 and V8 power with available all-wheel drive. It blended Art and Science styling with a more traditional luxury focus, competing against mid-to-full-size German and Japanese sedans. A high-performance STS-V used a supercharged Northstar V8. On WhipJury, the STS appears as a comfortable, rear-drive used luxury sedan with available V8 power.
