The Lucerne is a large, front-wheel-drive four-door sedan that replaced the LeSabre and the Park Avenue.
The standard powerplant is a rough-sounding 3.8-liter V6; a potent 4.6-liter, 275-hp V8 powers the CXS.
The four-speed automatic transmission shifts smoothly enough.
The Lucerne has a quiet and comfortable ride, especially at low speeds.
Handling is not agile and the steering lacks feedback.
A tendency to fishtail easily at its limits reduces confidence.
Stability control was available only on the CXS V8, and helped counteract that tendency.
Braking is unimpressive.
The roomy backseat is better than the one in the LaCrosse.
The last year for the Lucerne was 2011.
