The Invicta received several updates for the 1961 model year.
It was the last year the 364 cubic inch Nailhead V8 engine was offered before the engine was retired.
The station wagon did not reappear until the 1962 model year.

1962 saw the debut of the Wildcat two-door hardtop within the Invicta series.
The Wildcat featured most of the interior trim of the Invicta Custom, which included standard bucket seats and upgraded door panels.
 Instead of the Invicta Custom's short console, however, the Wildcat had a long console with a tachometer and a shift lever.
Other Wildcat features included special badging and exterior trim, along with a vinyl top and Electra 225-like taillights, rather than those of the LeSabre/Invicta.
These features placed the Wildcat well in step with the shift towards sports-oriented models.

For 1963, the Wildcat would replace the Invicta four-door hardtop, two-door coupe, and convertible.
The Invicta series had a 6-passenger station wagon as its sole model.
Only 3,495 Invicta station wagons were built for 1963, after which the name disappeared.
