Lincoln Mark VIII: which version to buy
The Lincoln Mark VIII ran as 1 generation (1992–1998) in Coupe form with 3 versions. There is no second generation to “wait for,” so the buying choice is entirely between 4.6 AT (284 hp), 4.6 AT (294 hp), and 5.4 AT. All three use Gasoline, a Front, longitudinal engine, 8 cylinders in a V-shaped layout, No boost, Distributed injection (multi-point), a 4-speed Automatic, RWD, and 95 fuel.

There is no second generation to “wait for,” so the buying choice is entirely between 4.6 AT (284 hp), 4.6 AT (294 hp), and 5.4 AT. All three use Gasoline, a Front, longitudinal engine, 8 cylinders in a V-shaped layout, No boost, Distributed injection (multi-point), a 4-speed Automatic, RWD, and 95 fuel. The useful differences are power, torque, 0–100, top speed, weight, clearance, rear suspension, and which figures are not measured.
Mark VIII specs by version (what actually differs)
| Version | hp | Nm | Displacement (cc) | Fuel | Cylinders / layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|
| 4.6 AT (284 hp) | 284 | 387 | 4601 | Gasoline | 8, V-shaped | No | Automatic, 4 | RWD |
| 4.6 AT (294 hp) | 294 | 400 | 4601 | Gasoline | 8, V-shaped | No | Automatic, 4 | RWD |
| 5.4 AT | 232 | 447 | 5398 | Gasoline | 8, V-shaped | No | Automatic, 4 | RWD |
Both 4.6 AT engines share 4601 cc, 4 valves per cylinder, compression 9.9, and bore × stroke 90.2 × 90. 5.4 AT is 5398 cc, 2 valves per cylinder, compression 9, and 90.2 × 105.7. Peak power sits at 5750 rpm on both 4.6 AT versions and at 4250 rpm on 5.4 AT. Peak torque sits at 4500 rpm on both 4.6 AT versions and at 3000 rpm on 5.4 AT.
Power per litre (hp ÷ displacement in litres): 4.6 AT (284 hp) 61.7 hp/l, 4.6 AT (294 hp) 63.9 hp/l, 5.4 AT 43.0 hp/l. The 294 hp 4.6 AT is the densest; 5.4 AT trades density for displacement and torque.
Performance, mpg, and economy: measured vs not measured
| Version | 0–100 | Top speed | City | Highway | Combined |
|---|---|---|---|---|---|
| 4.6 AT (284 hp) | 7.9 | 215 | not measured | not measured | not measured |
| 4.6 AT (294 hp) | 7.9 | 215 | 13.8 | 9.4 | 11.8 |
| 5.4 AT | 7.1 | 200 | not measured | not measured | not measured |
5.4 AT reaches 100 km/h 0.8 s sooner than either 4.6 AT (7.1 vs 7.9). That is the only acceleration gap in the data. Top speed goes the other way: both 4.6 AT versions are listed at 215, 5.4 AT at 200 — 15 km/h less.
Fuel use is measured only for 4.6 AT (294 hp): 13.8 city / 9.4 highway / 11.8 combined. For 4.6 AT (284 hp) and 5.4 AT, city, highway, and combined consumption are not measured. CO2 and eco class are not measured on all three. Do not treat the 294 hp 4.6 AT figures as if they applied to the other two.
Tank volume is 68 on every version.
Dimensions, weight, ground clearance, wheels
Kerb weight: 1715 on both 4.6 AT versions, 1730 on 5.4 AT (15 kg more). Gross weight: 2175 on 4.6 AT (284 hp) and on 5.4 AT; not measured on 4.6 AT (294 hp). Payload from the two measured pairs: 2175 − 1715 = 460 kg on 4.6 AT (284 hp); 2175 − 1730 = 445 kg on 5.4 AT.
Ground clearance: 160 on 4.6 AT (294 hp); not measured on 4.6 AT (284 hp) and 5.4 AT. Wheel sizes: not measured on all three.
Front brakes Disc, rear brakes Disc on all three. Front suspension Independent, pneumatic on all three. Rear suspension: Independent, pneumatic on 4.6 AT (284 hp) and 5.4 AT; Independent, spring on 4.6 AT (294 hp). That rear-end difference is the chassis split inside the 4.6 pair.
Weight per horsepower: 4.6 AT (284 hp) 6.04 kg/hp (1715 ÷ 284), 4.6 AT (294 hp) 5.83 kg/hp (1715 ÷ 294), 5.4 AT 7.46 kg/hp (1730 ÷ 232). The 294 hp 4.6 AT is the lightest per horsepower; 5.4 AT is the heaviest per horsepower.
Which Mark VIII version to choose
There is 1 generation and 3 Coupe versions, all dated 1992–1998. Generation-to-generation change is not a factor. The arithmetic is version-to-version.
Choose 4.6 AT (294 hp) if you want the strongest 4.6 and the only measured mpg
Versus 4.6 AT (284 hp): +10 hp (294 vs 284), +10 kW (216 vs 209), +13 Nm (400 vs 387), same 4601 cc, same 7.9 to 100, same 215 top speed, same 1715 kerb weight. Specific output rises from 61.7 to 63.9 hp/l; mass per hp falls from 6.04 to 5.83 kg/hp. You also get the only consumption set (13.8 / 9.4 / 11.8) and the only measured clearance (160). The trade: rear suspension is Independent, spring instead of Independent, pneumatic, and gross weight is not measured.
Versus 5.4 AT: +62 hp (294 vs 232), +45 kW (216 vs 171), but −47 Nm (400 vs 447). Displacement is 797 cc smaller (4601 vs 5398). 0–100 is 0.8 s slower (7.9 vs 7.1); top speed is 15 km/h higher (215 vs 200). Kerb weight is 15 kg lower (1715 vs 1730). Power per litre is 20.9 hp/l higher (63.9 vs 43.0). Mass per hp is 1.63 kg/hp lower (5.83 vs 7.46). 5.4 AT has no measured mpg; this 4.6 AT does.
Choose 4.6 AT (284 hp) if you want pneumatic rear suspension and a measured gross weight on the 4.6
It matches 4.6 AT (294 hp) on 0–100 (7.9), top speed (215), displacement (4601), valves (4), compression (9.9), kerb weight (1715), tank (68), drive (RWD), and gearbox (Automatic, 4). It is 10 hp and 13 Nm down. Rear suspension stays Independent, pneumatic (same as 5.4 AT). Gross weight is 2175, so payload is 460 kg. City, highway, combined, CO2, eco class, clearance, and wheels are not measured. Use this version when the pneumatic rear and the 2175 gross figure matter more than the extra 10 hp and the only mpg table.
Choose 5.4 AT if you want peak torque and the shortest 0–100
5.4 AT is the torque leader at 447 Nm at 3000 rpm: +60 Nm versus 4.6 AT (284 hp) and +47 Nm versus 4.6 AT (294 hp). It is also the only version with 2 valves per cylinder and the longer stroke (90.2 × 105.7 vs 90.2 × 90). Power is the lowest: 232 hp at 4250 rpm — 52 hp below the 284 hp 4.6 AT and 62 hp below the 294 hp 4.6 AT. Compression is 9 versus 9.9. 0–100 is the best listed figure at 7.1; top speed is the lowest at 200. Kerb weight 1730, gross 2175, payload 445 kg. Front and rear suspension Independent, pneumatic. Fuel consumption, CO2, eco class, clearance, and wheels: not measured.
If the buying question is “fastest to 100 in this catalogue,” 5.4 AT is the answer by 0.8 s. If the question is “highest listed speed,” both 4.6 AT versions at 215. If the question is “highest hp and only mpg numbers,” 4.6 AT (294 hp). If the question is “4.6 with pneumatic rear and a known gross weight,” 4.6 AT (284 hp).
Problems, reliability, and what the numbers do not say
This dataset does not include failure rates, service intervals, or used-car prices. What it does show is where two cars with the same name 4.6 AT are not the same car: 10 hp, 13 Nm, rear Independent, spring versus Independent, pneumatic, clearance 160 versus not measured, mpg measured versus not measured, gross not measured versus 2175. Mixing those two 4.6 AT listings as one spec sheet is a buying error.
5.4 AT is not a “bigger 4.6.” It is 797 cc larger, 2 valves per cylinder instead of 4, lower compression (9 vs 9.9), lower peak rpm (4250 vs 5750 for power; 3000 vs 4500 for torque), 232 hp instead of 284 or 294, 447 Nm instead of 387 or 400, 7.1 instead of 7.9 to 100, 200 instead of 215 top speed, and 1730 instead of 1715 kerb weight.
Short pick
- 4.6 AT (294 hp): most hp (294), highest hp/l (63.9), lowest kg/hp (5.83), only measured mpg (13.8 / 9.4 / 11.8), only measured clearance (160); rear Independent, spring; gross not measured.
- 4.6 AT (284 hp): same 7.9 / 215 as the 294 hp 4.6 AT, rear Independent, pneumatic, gross 2175; 10 hp and 13 Nm less; mpg not measured.
- 5.4 AT: most Nm (447), best 0–100 (7.1), pneumatic both ends, gross 2175; least hp (232), lowest top speed (200), mpg not measured.
One generation, three versions, same RWD Automatic Coupe envelope. The version to buy is the one whose measured column (hp, Nm, 0–100, top speed, weight, rear suspension, mpg) matches the job; the rest of the sheet is not measured, not implied.
