The Buick Electra is a full-size luxury car manufactured and marketed by Buick from 1959 to 1990 over six generations — having been named after heiress and sculptor Electra Waggoner Biggs by her brother-in-law Harlow H. Curtice, former president of Buick and later president of General Motors. The Electra was offered in coupe, convertible, sedan, and station wagon body styles over the course of its production — with rear-wheel drive (1959-1984) or front-wheel drive (1985-1990, except station wagon). For its entire production run, it utilized some form of GM's C platform. The Electra was superseded by the Buick Park Avenue in 1991.
Third generation (1954-1970)
All GM passenger vehicles received a major redesign in 1965 dominated by flowing "Coke bottle" lines and fastback roof profiles on its coupe models, and the 6 window-body style was eliminated. For 1965, Buick also changed its marketing strategy and offering the Electra 225 in two trim levels, base and Custom. Along with the new body came a new chassis with a full perimeter frame including side rails that replaced the previous "X" frame used since 1961. Engine offerings were unchanged from 1964 including the standard 325 hp (242 kW) 401 V8, and two versions of the larger 425 V8 that were rated at 340 hp (254 kW) with a four-barrel carburetor or 360 hp (268 kW) with two four barrels. The three-speed Super Turbine 400 automatic transmission was standard equipment. A new body style introduced for 1965 was the thin-pillar 4-door sedan, which featured frameless window glass with a thin, chrome fixed "B" pillar.
The 1966 Electra 225 saw only minor styling changes including a new grille and a revised full-width taillight and trunk lid that included an "Electra 225" script rather than the "BUICK" nameplate spelled out in 1965. Engine offerings were unchanged from 1965 with the exception that the dual-quad 360 hp (268 kW) 425 was downgraded from a factory option to dealer-installed. Inside, a revised instrument panel featured a horizontal sweep speedometer, fuel gauge and warning lights. Front seat headrests became an option.
A moderate facelift highlighted the 1967 Electra 225 including a Pontiac/Oldsmobile-like divided split grille. Both base and Custom models were continued with a new "Limited" option package available Electra 225 Custom 4-door hardtop reviving a nameplate that graced Buick's ultra-luxury flagship in the late 1930s (and again in 1958), which included an ultra-luxurious interior trim. Under the hood a new 430 cubic-inch V8 rated at 360 hp (268 kW) with four-barrel carburetor replaced the previous "Nailhead" 401 and 425 V8s. Power front disc brakes were available as a new option along with a stereo 8-track tape player.
The 1968 Electra 225 received a revised grille and taillight trim along with concealed windshield wipers. Inside, there was a revised instrument panel with a square speedometer and other instruments, plus a new steering wheel. Shoulder seat-belts were standard for both the driver and front passenger. Base and Custom models were still offered, with the Limited trim option available on the Electra 225 Custom hardtop sedan.
1969 brought a major restyling to the Electra 225 and other GM B-body and C-body cars with somewhat crisper bodylines than 1965–68 models, but continued with the same chassis and inner body structure introduced with the 1965 model, however the wheelbase was increased one inch to 127 in (3,226 mm). The 1969s were also the first to offer headrests as standard equipment due to a federal safety mandate, and the steering column with ignition switch that also locked the steering wheel with the transmission in "Park", a feature found on all 1969 GM cars one year before it became a federal safety mandate in 1970. Also new was a variable-ratio power steering system combined with revised front suspension tuning called "Accu-Drive." Other changes included ventless front windows. The same assortment of base and Custom models were offered in 1969 with the "Limited" trim package available on Custom sedans and coupes. A new option available with the Limited package was a split 60/40 bench seat with center armrest. Finned aluminum drum brakes were again offered as standard equipment, while the Bendix four-piston disk brake units were also available. 12" x 1" vented steel rotors were coupled with the cast iron caliper assemblies. A dual exhaust was available as an option. Five different rear axles were available: a 2.56 Economy as well as 2.73, 3.08, 3.23:1 gear ratios. The special PX-Code "AC Delete" 3.91 performance gear option was also available. The standing quartermile was completed in 15.5 seconds at a terminal velocity of 90 mph (145 km/h) for the dual exhaust engine with the 2.73 gear ratio in a 4,700 lb (2,132 kg) Custom Convertible.
Only a minor facelift with revised grille and taillight trim marked the 1970 Electra 225. The big news was under the hood, where a new 370 hp (276 kW) 455 cubic-inch V8 replaced the 430 V8 used from 1967 to 1969. This was the final year for the Electra convertible, finned aluminum brake drums and high compression engines. New this year was a concealed radio antenna, which amounted to two wires embedded in the windshield. Also new for 1970 was the Estate Wagon, which shared the Electra's 455 V8 and four VentiPorts, but was a B-body car like the LeSabre and the Wildcat and consequently shared the smaller cars' 124.0-inch (3,150 mm) wheelbase and interior. This was Buick's first full-sized station wagon since 1964. The following year the Buick Estate would move up to Electra's larger body and more voluminous interior.
