Lincoln Mark III: which version to buy

If you are choosing a Lincoln Mark III from this catalogue, the decision is already made by the data: there is 1 generation (1968-01-01 to 1971-12-31), Coupe body only, and 1 version — 7.5 AT. There is no second engine, no restyle as a separate generation, and no later generation to trade against.

If you are choosing a Lincoln Mark III from this catalogue, the decision is already made by the data: there is 1 generation (1968-01-01 to 1971-12-31), Coupe body only, and 1 version — 7.5 AT. There is no second engine, no restyle as a separate generation, and no later generation to trade against. What you are buying is that one specification, and the arithmetic below is what that specification actually is.

Which generation changed what

The catalogue lists 1 generation. Production of 1 generation runs from 1968-01-01 to 1971-12-31. Body type is Coupe. Number of versions in 1 generation: 1 (7.5 AT).

There is no second generation to compare, so nothing in this catalogue “changed” from generation 1 to generation 2: there is no generation 2. Years, body, engine, gearbox, and drive of 7.5 AT are the same window as the generation itself (start 1968-01-01, stop 1971-12-31). Restyling is not listed as a separate generation and is not listed at all.

If your question is “which generation to buy,” the only generation in the data is 1 generation. Buying a Mark III in this catalogue means buying 1 generation, Coupe, 7.5 AT.

Specs of the only version: 7.5 AT

7.5 AT is the sole modification. Named exactly as in the data: 7.5 AT.

Further figures that belong to 7.5 AT and nowhere else in this catalogue:

Gross weight: not measured. Ground clearance: not measured. Wheel sizes: not measured. Eco class: not measured. CO2: not measured.

Engine: what 370 hp and 7536 cc buy you

There is no second engine to pick. The comparison is internal: how much power and torque 7.5 AT extracts from 7536 cc, and how that sits against the 2152 kerb weight.

Power per litre for 7.5 AT: 370 hp ÷ (7536 / 1000) = 370 ÷ 7.536 ≈ 49.1 hp per litre. In kilowatts: 272 kW ÷ 7.536 ≈ 36.1 kW per litre.

Torque per litre: 678 Nm ÷ 7.536 ≈ 90.0 Nm per litre.

Valves in total: 8 cylinders × 2 valves per cylinder = 16 valves. Boost is No, so those 370 hp and 678 Nm are the naturally aspirated figures in the data, not a boosted pair.

Peak torque (678 Nm) is listed at 2800 rpm; peak power (370 hp / 272 kW) at 4600 rpm. The gap is 4600 − 2800 = 1800 rpm between the torque peak and the power peak. Compression is 10.5. Fuel is 92. Fuel system is Carburetor.

Bore and stroke for 7.5 AT are 110.7 × 97.8. Bore minus stroke: 110.7 − 97.8 = 12.9 (bore larger than stroke). That is the only bore/stroke pair in the catalogue.

Displacement 7536 cc with 8 V-shaped cylinders is the only engine size listed. You cannot “step down” to a smaller engine or “step up” to a larger one: those versions are not in the data.

Gearbox, drive, and what extra money cannot buy

7.5 AT is Automatic with 3 gears and RWD. There is no manual, no 4-speed, no FWD, and no AWD in this catalogue. If you wanted a different gearbox or a different drive, this model’s data does not offer it.

Engine position is Front, longitudinal. That is the only layout listed.

Because there is only one version, “what the extra money buys” cannot be answered as a price delta: prices are not in the data. What the single specification buys, in numbers, is 370 hp, 678 Nm, 7536 cc, Automatic 3, RWD, tank 91, kerb 2152.

Weight per horsepower and dimensions

Kerb weight of 7.5 AT is 2152. Gross weight: not measured. Ground clearance: not measured. Wheel sizes: not measured. Tank: 91.

Weight per horsepower: 2152 ÷ 370 ≈ 5.82 kg per hp. Weight per kilowatt: 2152 ÷ 272 ≈ 7.91 kg per kW.

Tank relative to kerb: 91 ÷ 2152 ≈ 0.0423 units of tank per unit of kerb weight (91 / 2152). There is no second tank size to compare.

You cannot choose a lighter or heavier Mark III from this catalogue: 7.5 AT is the only kerb weight (2152). You cannot choose a different clearance or a different wheel size: both are not measured.

Performance and mpg: what is not measured

0–100 for 7.5 AT: not measured. Top speed for 7.5 AT: not measured. City fuel consumption: not measured. Highway fuel consumption: not measured. Combined fuel consumption: not measured. CO2: not measured. Eco class: not measured.

A buying choice based on 0–100, top speed, or mpg cannot be made from this catalogue, because those figures are not measured for 7.5 AT. The measured performance-related numbers you do have are 370 hp at 4600 rpm, 678 Nm at 2800 rpm, 2152 kerb, Automatic 3, RWD, and the ratios above (≈49.1 hp/L, ≈5.82 kg/hp).

Problems and reliability: what the spec sheet does and does not say

This catalogue does not list failure rates, recalls, or reliability scores. Those are not measured here.

What the sheet does fix for 7.5 AT: Carburetor (not another fuel system), boost No, 8 V-shaped cylinders, 2 valves per cylinder, Front, longitudinal, Independent, spring front, Dependent, spring rear, front brakes Disc, rear brakes Drum, Automatic 3, RWD, fuel 92, compression 10.5, tank 91, kerb 2152.

Front and rear brakes are not the same type: Disc in front, Drum at the rear. Front and rear suspension are not the same type: Independent, spring in front, Dependent, spring at the rear. Those are the only brake and suspension pairings listed.

Which version to choose

There is one named version: 7.5 AT. There is no second 7.5 AT with a different horsepower, so you do not split the name by 370 vs another hp figure.

Choose 7.5 AT if you want the only Mark III in this catalogue: 1 generation (1968-01-01–1971-12-31), Coupe, 370 hp / 272 kW at 4600 rpm, 678 Nm at 2800 rpm, 7536 cc, fuel 92, 8 V-shaped, 2 valves per cylinder, boost No, Carburetor, compression 10.5, Front, longitudinal, Automatic 3, RWD, tank 91, kerb 2152, ≈49.1 hp per litre, ≈5.82 kg per hp.

Do not expect to choose by 0–100, top speed, mpg, gross weight, ground clearance, wheels, CO2, or eco class: those are not measured. Do not expect a second generation or a second engine: pokoleniy is 1 and modifikaciy is 1.

That is the whole buying set: 7.5 AT, or this model is not the one you are choosing from this catalogue.
