It featured a red and white fiberglass body, airplane-like interior design, a fully clear "bubble top" roof and the first backup camera in place of a rear-view mirror, although it was never shown to be functional.

The two-door hardtop shared the handsome semi-fastback roofline with the LeSabre and other GM B-body cars (such as the Chevrolet Impala Sport Coupe and the Olds Delta 88) along with a standard vinyl roof.

The Centurion was offered initially with only the 455-cubic-inch (7.5 L) big-block V8 in two power output ranges determined by the presence of either a single or dual exhaust.

The Centurion was also offered in the 455 Stage 1 and manual transmission configuration as well during the early portion of the 1971 model year, shared with the Buick GSX.

Interior trim was upgraded from LeSabres with a notchback bench seat including center armrest standard equipment along with more luxurious cloth-and-vinyl or all-vinyl upholstery.
