Which Buick Electra Version Should You Buy?
The Buick Electra version to choose depends on whether you prioritize outright output, lower engine capacity, or a later drivetrain layout.
The Buick Electra version to choose depends on whether you prioritize outright output, lower engine capacity, or a later drivetrain layout. Among the four documented versions, the 1971–1976 7.5 AT is the strongest overall proposition for maximum torque, with 488 Nm and 228 hp, while the 1959–1960 6.0 AT produces the highest power at 254 hp and the best power-to-displacement figure at about 42.6 hp per litre. The 1985–1990 3.8 AT is the smallest-engine option and the only version here with FWD, a 4-speed Automatic gearbox, and Distributed injection (multi-point). The 1977–1984 4.1 AT sits between the older and newer layouts, combining RWD and a 3-speed Automatic gearbox with 125 hp.
Buick Electra generations compared
The first generation, produced from 1959 to 1960, is represented by a Cabrio and one version, 6.0 AT. Its 5,957 cc Gasoline V-shaped 8-cylinder engine produces 254 hp at 4,400 rpm and 515 Nm at 2,400 rpm. Power is sent through a 2-speed Automatic gearbox to RWD. This generation offers the highest horsepower and torque of all versions in the supplied data.
The second generation ran from 1961 to 1964 as a Cabrio. It has no documented versions in the supplied catalogue data, so its engine, gearbox, drive, performance, economy, dimensions, and weight cannot be compared and are not measured here.
The third generation, built from 1965 to 1970, is also listed as a Cabrio with no documented versions. Consequently, figures for searches such as 1969 or 1970 Buick Electra specs—including engine size and horsepower—are not measured in this data.
The fourth generation covers 1971 to 1976 and uses a Coupe Hardtop body. Its single version is 7.5 AT, powered by a front, longitudinal 7,468 cc Gasoline V-shaped 8-cylinder engine. It develops 228 hp at 4,000 rpm and 488 Nm at 2,600 rpm, paired with a 3-speed Automatic gearbox and RWD. This is the only version with a documented kerb weight: 2,315 kg.
The fifth generation was offered from 1977 to 1984 as a Coupe, with one documented version: 4.1 AT. Its 4,130 cc Gasoline V-shaped 6-cylinder engine delivers 125 hp at 4,000 rpm and 278 Nm at 2,000 rpm through a 3-speed Automatic gearbox and RWD. Compared with 7.5 AT, it uses 3,338 cc less displacement but also gives up 103 hp and 210 Nm.
The sixth generation, produced from 1985 to 1990, is a Coupe with one version, 3.8 AT. Its 3,791 cc Gasoline V-shaped 6-cylinder engine produces 175 hp at 4,700 rpm and 305 Nm at 3,200 rpm. A 4-speed Automatic gearbox and FWD distinguish it from every earlier documented version. Against 4.1 AT, it has 339 cc less capacity yet adds 50 hp and 27 Nm.
Buick Electra engine and specs
| Generation and version | Engine | Power | Torque | Fuel | Cylinders and layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|
| 1959–1960 6.0 AT | 5,957 cc | 254 hp | 515 Nm | Gasoline | 8, V-shaped | No | 2-speed Automatic | RWD |
| 1971–1976 7.5 AT | 7,468 cc | 228 hp | 488 Nm | Gasoline | 8, V-shaped | not measured | 3-speed Automatic | RWD |
| 1977–1984 4.1 AT | 4,130 cc | 125 hp | 278 Nm | Gasoline | 6, V-shaped | No | 3-speed Automatic | RWD |
| 1985–1990 3.8 AT | 3,791 cc | 175 hp | 305 Nm | Gasoline | 6, V-shaped | No | 4-speed Automatic | FWD |
Displacement alone does not determine output. The 6.0 AT makes approximately 42.6 hp per litre, compared with about 30.5 hp per litre for 7.5 AT, 30.3 hp per litre for 4.1 AT, and 46.2 hp per litre for 3.8 AT. On this measure, 3.8 AT leads the group, producing about 15.7 hp per litre more than 7.5 AT despite having 3,677 cc less displacement.
The 3.8 AT also has Distributed injection (multi-point), while 6.0 AT uses a Carburetor. The fuel system is not measured for 7.5 AT and 4.1 AT. The compression ratios are 8.5 for 6.0 AT, 8.5 for 7.5 AT, 8 for 4.1 AT, and 9 for 3.8 AT.
Buick Electra performance and economy
Acceleration from 0–100 km/h is not measured for 6.0 AT, 7.5 AT, 4.1 AT, and 3.8 AT. Top speed is likewise not measured for all four versions.
City, highway, and combined fuel consumption are not measured for every documented version. No mpg comparison can therefore be made from the supplied figures. CO₂ output and environmental class are also not measured across the range.
The available output figures still establish clear differences. 6.0 AT has 26 hp and 27 Nm more than 7.5 AT. In turn, 7.5 AT exceeds 4.1 AT by 103 hp and 210 Nm. The later 3.8 AT reverses part of that decline, beating 4.1 AT by 50 hp and 27 Nm while using the smaller engine.
Buick Electra dimensions, weight, and capacity
Complete exterior dimensions, including length, width, and height, are not measured for every generation and version. Gross weight and wheel sizes are also not measured throughout the supplied data.
| Version | Kerb weight | Gross weight | Ground clearance | Fuel tank | Wheel sizes |
|---|---|---|---|---|---|
| 6.0 AT | not measured | not measured | not measured | not measured | not measured |
| 7.5 AT | 2,315 kg | not measured | not measured | 95 L | not measured |
| 4.1 AT | not measured | not measured | not measured | not measured | not measured |
| 3.8 AT | not measured | not measured | 110 mm | 68 L | not measured |
For 7.5 AT, the documented 2,315 kg kerb weight and 228 hp produce a weight-to-power ratio of approximately 10.2 kg per hp. No equivalent comparison is possible for the other versions because their kerb weights are not measured. The 7.5 AT tank holds 27 L more than the 68 L tank of 3.8 AT.
The 3.8 AT, 4.1 AT, and 7.5 AT all use Independent, spring front suspension. Their rear layouts differ: 3.8 AT and 4.1 AT retain Independent, spring suspension, whereas 7.5 AT uses Dependent, leaf spring suspension. The rear suspension of 6.0 AT is not measured.
Which Buick Electra version to choose
Choose 3.8 AT when the priority is the smallest displacement and the highest power per litre. Its 3,791 cc engine makes 175 hp and 305 Nm, while its 4-speed Automatic gearbox provides one more gear than 4.1 AT and 7.5 AT, and two more than 6.0 AT. It is also the only documented FWD version and the only one with Distributed injection (multi-point).
Choose 6.0 AT for maximum documented output. Its 254 hp exceeds 7.5 AT by 26 hp, 3.8 AT by 79 hp, and 4.1 AT by 129 hp. Its 515 Nm is also the highest figure, although the gearbox has only 2 speeds and performance and consumption remain not measured.
Choose 7.5 AT if the combination of a Coupe Hardtop body, the largest engine, and strong output matters most. It offers 7,468 cc, 228 hp, and 488 Nm. It is also the only choice whose kerb weight is documented, permitting the calculated ratio of about 10.2 kg per hp. Its 95 L tank is the largest measured capacity, but range cannot be calculated because fuel consumption is not measured.
Choose 4.1 AT for the 1977–1984 Coupe generation and its RWD, 3-speed Automatic configuration. Numerically, however, 3.8 AT is the stronger six-cylinder choice: it produces 50 hp and 27 Nm more from 339 cc less displacement. Without price, condition, reliability, or repair data, there is no factual basis for claiming that 4.1 AT is cheaper or easier to own.
For the broadest specification advantage, 3.8 AT is the most balanced choice in the available data. For peak horsepower and torque, 6.0 AT is the clear selection. Prices and current vehicles for sale are not included, so purchase value must be judged separately from these specifications.
