Willys MB: which version to buy

The Willys MB catalogue entry covers 1 generation (1941–1945) and 1 named version: 2.2 MT.

The Willys MB catalogue entry covers 1 generation (1941–1945) and 1 named version: 2.2 MT. There is no second engine, no restyling row, and no automatic alternative in these data, so a buyer is not choosing between MB trims — the arithmetic below is how to read 2.2 MT against its own figures (power per litre, mass per horsepower, speed versus clearance, tank versus kerb weight) and against the fields that are not measured.

Which generation to buy

1 generation (1941-01-01 to 1945-12-31) is the only production window. Body: SUV cabriolet. Versions in this generation: 1.

That means a “later facelift,” a “pre-restyling,” or an “11th generation listed three times” pattern does not apply. Years, body, and the single modification sit in one block. If the question is generation versus generation, the data give no second generation to subtract from: production start and stop for both the generation and 2.2 MT are the same dates, 1941-01-01–1945-12-31.

Specs: the only named version

Use the database name exactly: 2.2 MT.

Further engine numbers that belong to 2.2 MT and not to a second row:

There are not two 2.2 MT lines with different horsepower, so no “same name, 299 vs 309 hp” split. One name, one power figure: 60 hp.

Engine: what 60 hp and 2199 cc actually buy

Power per litre (2.2 MT): 60 ÷ (2199 / 1000) = 27.3 hp per litre (60 / 2.199).

That is the specific output of this Gasoline 4-cylinder Inline unit with boost No. The extra displacement versus a round “2.0” label is 199 cc (2199 − 2000); the catalogue does not list a 2.0 sibling, so that 199 cc is not “what you pay extra for versus another MB” — it is simply the published capacity of 2.2 MT.

Torque versus power: 142 Nm against 60 hp. Per horsepower, torque is 142 ÷ 60 = 2.37 Nm per hp. Peak power is tied to 3600 rpm; peak torque rpm is not measured, so you cannot rank this engine on “low-rpm pull” from a torque-rpm number that is not in the data.

Compression 6.48 with Carburetor and boost No is the induction package as listed. Cylinder count is 4, layout Inline — not a guessed V or six. Valves per cylinder 2.

Layout of the car, not the block: engine Front, longitudinal, drive AWD, gearbox Manual with 3 gears. There is no second gearbox in the table, so “what the extra money buys” cannot be Automatic versus Manual: only Manual / 3 / AWD exists here.

Performance and mpg

For 2.2 MT:

A buyer comparing “which is quicker” has no 0–100 to subtract. The only speed figure is top speed 104. Fuel use in city, highway, mixed, and mpg terms is not measured — omitting those lines would look as if the car had no such parameters; the data simply do not measure them.

Speed versus clearance (same version): ground clearance is 220 and top speed is 104. Those two numbers sit on one car; there is no second MB with less clearance and more speed to trade against.

Dimensions, weight, tank, wheels

2.2 MT:

Mass per horsepower: 1020 ÷ 60 = 17.0 kg per hp. That is the kerb-weight load on each of the 60 hp. Gross mass is not measured, so payload (gross minus kerb) cannot be calculated without inventing a number.

Tank versus kerb: 57 litres of tank on a 1020 kerb. Litres per 100 kg of kerb: 57 ÷ 10.20 = 5.59 L per 100 kg. Range from tank × mpg cannot be stated: consumption is not measured.

Wheels: size not measured. Do not treat missing wheel data as “no wheels”; the field is empty in the source.

Which version to choose

Choose 2.2 MT because it is the only named version in these data. Arithmetic on that row, not a trim ladder:

1. Power density: 27.3 hp/L from 60 hp and 2199 cc. 2. Weight penalty: 17.0 kg/hp from 1020 kg and 60 hp. 3. Drivetrain: AWD + Manual + 3 gears — no two-wheel-drive or Automatic MB in the table to “save money” on. 4. Body and years: SUV cabriolet, 1 generation, 1941–1945. No later generation with more hp or less mass. 5. What you cannot buy with a second checkbox: a faster 0–100 ( not measured ), a different mpg ( not measured ), a different wheel size ( not measured ), a higher-output twin of the same name, or a restyle inside another generation key.

Problems / reliability: the launch data do not include failure rates, common faults, or service intervals. Those topics are not measured here; do not fill them from outside knowledge.

Bottom line: the Willys MB in this catalogue is one generation, one body (SUV cabriolet), one version name (2.2 MT): Gasoline 4 Inline, boost No, 60 hp, 142 Nm, 2199 cc, Manual 3, AWD, kerb 1020, tank 57, clearance 220, top speed 104. The buying decision is whether those measured numbers (and the explicit not measured gaps) match the use case — not which of several MB versions to pick.
