Executives featured more deluxe trim, more standard amenities and a longer wheelbase and overall length than the lower-priced Catalina models, but were not quite as luxurious as the top-line Bonneville, whose wheelbase and other dimensions the Executive shared.

Mechanically, the Executive was virtually identical to the Catalina, sharing similar standard and optional V8 engines starting with the base 400 CID V8 with two-barrel carburetor rated at 265 hp (198 kW), and ending with a 390 hp 428 CID HO V8 through 1969 and a larger 455 CID V8 rated at 370 hp (276 kW) in 1970.

The standard transmission each year was a three-speed manual with column shift, with a floor-mounted four-speed with Hurst shifter optional in 1967 and 1968.

However, 98 percent of Executives were equipped with the three-speed Turbo Hydra-Matic automatic during the model's four-year run.

Executives were available as a four-door pillared sedan, two-door hardtop coupe, four-door hardtop sedan, and Safari station wagons in two and three-seat versions.
