Subaru 360 specs: which version to buy
The Subaru 360 was built in 1 generation from 1958-01-01 to 1971-12-31. The body in the data is Coupe. Across that span the catalogue records 1 version: 0.4 MT. There is no restyling listed as a separate generation, and there is no second named modification. Extra money does not buy another engine, another gearbox, or another drive layout in this dataset: those fields do not vary.

If you are choosing a Subaru 360 from this catalogue, the answer is 0.4 MT or nothing. The rest of this article is the arithmetic of that one package: what 16 hp from 356 cm³ actually is, what 37 s to 100 km/h and a 100 km/h top speed imply, and which measurements you still do not have.
Generations: what changed (and what did not)
1 generation (1958-01-01–1971-12-31), Coupe, 1 version. Production covers the full window from the start date of 0.4 MT to the same stop date. Body type does not change in the data. Version count is 1, so there is no mid-cycle jump from a weaker 0.4 MT to a stronger 0.4 MT, and no second name to distinguish by horsepower.
What this generation did not change, because there is nothing else to change to: engine placement stays Rear; drive stays RWD; gearbox stays Manual with 3 speeds; fuel type stays Gasoline; boost stays No; cylinders stay 2 in an Inline layout with 2 valves per cylinder; induction stays Carburetor. Front suspension is Independent, spring; front brakes are Drum. Rear suspension, rear brakes, kerb weight, gross weight, ground clearance, tank, wheels, torque, fuel use, and CO2 are not measured for this generation.
A buyer looking for “the later 360” or “the more powerful 360” will not find a second generation or a second version in these numbers. The production window is long (1958 through 1971), but the mechanical line in the catalogue is one row.
Engines and specs
The only engine-and-transmission row is 0.4 MT. Displacement is 356 cm³. Output is 16 hp (12 kW) at 4500 rpm. Torque in Nm is not measured; torque rpm is not measured. Fuel is Gasoline. Cylinders: 2, layout Inline, valves per cylinder 2. Boost: No. Engine location: Rear. Fuel system: Carburetor. Gearbox: Manual, 3 speeds. Drive: RWD. Compression ratio is not measured. Bore and stroke are not measured.
| Version | hp | kW | Nm | Displacement (cm³) | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|---|
| 0.4 MT | 16 | 12 | not measured | 356 | Gasoline | 2 | Inline | No | Manual, 3 | RWD |
Power per litre for 0.4 MT is 16 ÷ 0.356 ≈ 44.9 hp per litre (12 ÷ 0.356 ≈ 33.7 kW per litre). That figure is specific output only; it is not a second version. Without a measured kerb weight, weight per horsepower is not measured. Without Nm, there is no torque-per-litre figure to put next to the 44.9 hp/l number.
0.4 MT is naturally aspirated (No boost). The 2-cylinder Inline Gasoline unit sits at the Rear and drives the rear wheels (RWD). The Manual box has 3 ratios, not a four- or five-speed alternative. There is no automatic row and no AWD row in the table.
Performance and economy
0.4 MT reaches 100 km/h in 37 s. Maximum speed is 100 km/h. Those two figures belong to this version only; they are not averaged across a range, because there is no range.
City fuel consumption is not measured. Highway fuel consumption is not measured. Combined fuel consumption is not measured. CO2 is not measured. Eco class is not measured. Fuel grade is not measured. A search for Subaru 360 mpg or l/100 km will not be answered by a number in this catalogue: write not measured, not an assumed kei-car average.
What the measured pair does say: 0.4 MT is specified to a 100 km/h ceiling, and the 0–100 run takes 37 s. If the use case is motorway pace above that ceiling, this version does not provide a higher-speed alternative. If the use case is a timed 0–100 comparison against another Subaru 360 in the same table, there is no other Subaru 360 in the same table.
Tank capacity is not measured, so range cannot be derived from consumption (which is also not measured).
Dimensions and weight
Kerb weight for 0.4 MT is not measured. Gross weight is not measured. Ground clearance is not measured. Wheel sizes are not measured. Tank is not measured.
Without kerb weight, you cannot compute kg per hp for 0.4 MT. Without gross weight, payload is not measured. Without wheel sizes, tyre load and rolling diameter are not measured. Front suspension is known: Independent, spring. Rear suspension is not measured. Front brakes are Drum. Rear brakes are not measured.
Body type is Coupe for the one generation. There is no second body (no wagon, no sedan row) to choose on space. Dimensions in millimetres are not in the launch data, so length, width, height, and wheelbase are not measured here.
Which version to choose
Choose 0.4 MT if you want the Subaru 360 as this catalogue defines it: 1 generation, Coupe, Rear Gasoline 2-cylinder Inline engine of 356 cm³, 16 hp / 12 kW at 4500 rpm, No boost, Carburetor, Manual 3-speed, RWD, 0–100 in 37 s, top speed 100 km/h, front Independent, spring suspension, front Drum brakes.
There is no second version, so there is no “extra money” comparison between two named rows. You cannot buy more hp, more Nm, more gears, or a different drive without leaving this model’s modification list. You also cannot buy a lighter or heavier official kerb figure: mass is not measured.
Decision checks against the numbers that exist:
- Power. 0.4 MT is 16 hp. Specific output is about 44.9 hp/l. If you need a higher hp figure, this catalogue does not list one for the Subaru 360.
- Speed. Top speed 100 km/h equals the 0–100 test speed; the sprint is 37 s. If you need a shorter 0–100 time or a higher Vmax, there is no other Subaru 360 version here.
- Gearbox. Manual, 3 speeds. No automatic, no extra ratio count.
- Drive and layout. RWD with Rear engine. No FWD or AWD variant.
- Fuel and boost. Gasoline, Carburetor, No turbo or supercharger.
- Economy and weight. Consumption, tank, CO2, eco class, kerb, gross, clearance, wheels: all not measured. Do not treat those blanks as “does not apply.”
Problems and reliability are not in the launch data; this article does not invent failure rates. What you can verify before you buy is that the mechanical identity is a single line: 0.4 MT, 1958-01-01 to 1971-12-31, Coupe, 16 hp, 356 cm³, Manual 3, RWD. If that line matches the car in front of you, it is the only catalogue version. If it does not, it is not a different Subaru 360 generation in this dataset — it is outside these specs.
