Lincoln Mark IV: Which Version Should You Choose?
The Lincoln Mark IV was produced from 1972 through 1976 as a Coupe in a single generation. Its catalogue contains four versions, all named 7.5 AT, so the clearest way to distinguish them is by output: 203 hp, 214 hp, 223 hp, or 228 hp. Every version uses the same 7,536 cc Gasoline V-shaped 8-cylinder engine, Carburetor fuel system, 3-speed Automatic gearbox, and RWD.
The Lincoln Mark IV was produced from 1972 through 1976 as a Coupe in a single generation. Its catalogue contains four versions, all named 7.5 AT, so the clearest way to distinguish them is by output: 203 hp, 214 hp, 223 hp, or 228 hp. Every version uses the same 7,536 cc Gasoline V-shaped 8-cylinder engine, Carburetor fuel system, 3-speed Automatic gearbox, and RWD. The principal choice is therefore between different power, torque, kerb-weight, and measured top-speed figures rather than different body styles or driveline layouts. On the available numbers, the 228 hp version offers the strongest engine specification, while the 214 hp version has the lowest kerb weight and best weight-to-power ratio.
Lincoln Mark IV generations and versions
There is only one Lincoln Mark IV generation in the catalogue, covering 1972–1976. It has a Coupe body and four listed versions. All four carry the exact 7.5 AT name, making their power ratings essential identifiers: 7.5 AT (203 hp), 7.5 AT (214 hp), 7.5 AT (223 hp), and 7.5 AT (228 hp). There is no second generation in the supplied data, so a buyer cannot compare generational changes; the meaningful comparison is entirely among these four power specifications within the same generation.
Lincoln Mark IV 7.5 AT engine and specs
The common foundation is highly consistent. Each 7.5 AT has a 7,536 cc Gasoline engine with 8 cylinders in a V-shaped layout, 2 valves per cylinder, no boost, and a Front, longitudinal installation. Every engine is fed by a Carburetor, has a compression ratio of 8, and uses a 110.74 × 97.8 bore-and-stroke specification. Power is delivered through a 3-speed Automatic gearbox to RWD.
| Version | Power | Torque | Displacement | Fuel | Cylinders and layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|
| 7.5 AT (203 hp) | 203 hp / 149 kW at 3,800 rpm | 471 Nm at 2,600 rpm | 7,536 cc | Gasoline | 8, V-shaped | No | 3-speed Automatic | RWD |
| 7.5 AT (214 hp) | 214 hp / 157 kW at 4,400 rpm | 458 Nm at 2,800 rpm | 7,536 cc | Gasoline | 8, V-shaped | No | 3-speed Automatic | RWD |
| 7.5 AT (223 hp) | 223 hp / 164 kW at 4,400 rpm | 481 Nm at 2,800 rpm | 7,536 cc | Gasoline | 8, V-shaped | No | 3-speed Automatic | RWD |
| 7.5 AT (228 hp) | 228 hp / 168 kW at 4,000 rpm | 496 Nm at 2,600 rpm | 7,536 cc | Gasoline | 8, V-shaped | No | 3-speed Automatic | RWD |
Because displacement is identical, power per litre makes the outputs easy to compare. The 7.5 AT (203 hp) produces approximately 26.9 hp per litre, the 7.5 AT (214 hp) 28.4 hp per litre, the 7.5 AT (223 hp) 29.6 hp per litre, and the 7.5 AT (228 hp) 30.3 hp per litre. Moving from 203 hp to 228 hp adds 25 hp and 25 Nm without changing displacement, gearbox, or drive.
The torque figures do not rise in exactly the same order as horsepower. The 7.5 AT (214 hp) develops 458 Nm, which is 13 Nm less than the 203 hp version’s 471 Nm. The 7.5 AT (223 hp) adds 23 Nm over the 214 hp specification, while the 7.5 AT (228 hp) adds another 15 Nm and reaches the group’s highest figure of 496 Nm. It also produces peak torque at 2,600 rpm, compared with 2,800 rpm for the 214 hp and 223 hp versions.
Lincoln Mark IV performance and mpg
Acceleration from 0–100 km/h was not measured for all four 7.5 AT versions. City fuel consumption, highway fuel consumption, and combined fuel consumption were also not measured for every version. As a result, the supplied specifications cannot support an mpg comparison or a claim that one engine output is more economical than another.
Top speed was measured for only two versions. The 7.5 AT (203 hp) has a measured maximum speed of 190 km/h, while the 7.5 AT (223 hp) reaches 200 km/h. That is a 10 km/h advantage for the 223 hp specification. Maximum speed is not measured for the 7.5 AT (214 hp) and 7.5 AT (228 hp), so the highest-power version cannot automatically be described as the fastest on the available evidence.
| Version | 0–100 km/h | Top speed | City consumption | Highway consumption | Combined consumption |
|---|---|---|---|---|---|
| 7.5 AT (203 hp) | not measured | 190 km/h | not measured | not measured | not measured |
| 7.5 AT (214 hp) | not measured | not measured | not measured | not measured | not measured |
| 7.5 AT (223 hp) | not measured | 200 km/h | not measured | not measured | not measured |
| 7.5 AT (228 hp) | not measured | not measured | not measured | not measured | not measured |
Lincoln Mark IV dimensions, weight, and tank capacity
External dimensions are not measured in the supplied data, and wheel sizes are not measured for every version. Ground clearance and gross weight are likewise not measured throughout the range. All four versions have a 100-litre fuel tank.
Kerb weight provides a useful distinction. The 7.5 AT (214 hp) weighs 2,297 kg, whereas the 7.5 AT (203 hp), 7.5 AT (223 hp), and 7.5 AT (228 hp) each weigh 2,428 kg. The 214 hp version is therefore 131 kg lighter than each of the other three.
| Version | Kerb weight | Gross weight | Ground clearance | Tank | Wheel sizes |
|---|---|---|---|---|---|
| 7.5 AT (203 hp) | 2,428 kg | not measured | not measured | 100 litres | not measured |
| 7.5 AT (214 hp) | 2,297 kg | not measured | not measured | 100 litres | not measured |
| 7.5 AT (223 hp) | 2,428 kg | not measured | not measured | 100 litres | not measured |
| 7.5 AT (228 hp) | 2,428 kg | not measured | not measured | 100 litres | not measured |
The resulting weight-to-power figures are approximately 12.0 kg per hp for the 7.5 AT (203 hp), 10.7 kg per hp for the 7.5 AT (214 hp), 10.9 kg per hp for the 7.5 AT (223 hp), and 10.6 kg per hp for the 7.5 AT (228 hp). The 228 hp version has the strongest ratio overall, but the lighter 214 hp version narrowly beats the heavier 223 hp version despite producing 9 hp less.
Suspension and brakes do not separate the four choices. Every version has Independent, spring front suspension and Dependent, leaf spring rear suspension. All use Disc front brakes and Drum rear brakes.
Lincoln Mark IV problems and reliability
Problems and reliability are not measured in the supplied data. No version-specific failure rates, repair records, or durability figures are available, so the 203 hp, 214 hp, 223 hp, and 228 hp versions cannot be ranked for reliability. Their shared engine displacement, fuel system, transmission type, drive layout, suspension descriptions, and brake types show specification similarity, but that similarity is not evidence of equal reliability.
Which Lincoln Mark IV 7.5 AT should you buy?
Choose the 7.5 AT (228 hp) when the strongest paper specification matters most. It leads with 228 hp and 496 Nm, offering 25 hp and 25 Nm more than the 203 hp version. It also has the best power density at approximately 30.3 hp per litre and the best weight-to-power ratio at roughly 10.6 kg per hp. Its maximum speed and 0–100 km/h time are not measured, however, so its numerical engine advantage should not be turned into an unsupported performance claim.
Choose the 7.5 AT (223 hp) if a measured top speed is important. Its recorded 200 km/h maximum is 10 km/h higher than the only other measured result, the 190 km/h of the 203 hp version. It also provides 481 Nm, which is 10 Nm above the 203 hp specification and 23 Nm above the 214 hp specification.
The 7.5 AT (214 hp) is the weight-focused choice. At 2,297 kg, it is 131 kg lighter than every other listed version. Its approximate 10.7 kg-per-hp ratio is only slightly behind the 228 hp version and better than the 223 hp version’s approximate 10.9 kg per hp. The trade-off is the lowest torque in the range at 458 Nm, and its top speed is not measured.
The 7.5 AT (203 hp) offers the least power and the weakest weight-to-power result, but it still develops 471 Nm at 2,600 rpm and has a measured 190 km/h maximum speed. It is the only alternative to the 223 hp version with a recorded top-speed figure.
No supplied price data shows what the extra power costs, so value for money cannot be calculated. Based strictly on the available specifications, the 7.5 AT (228 hp) is the most convincing all-round numerical choice, the 7.5 AT (223 hp) is the choice with the highest measured top speed, and the 7.5 AT (214 hp) is the notably lighter option.
