BMW 340 generations: what changed (and what did not)
Because the generation count is 1, a buyer cannot “step up a generation” for more power, a different gearbox, or another drive layout. Production window arithmetic: from the first day of 1949 through the last day of 1955 is the entire run of this model in the data.
1 generation ran from 1949-01-01 to 1955-12-31. Body: Sedan. Versions in the sheet: 1 (`modifikaciy`: 1). There is no restyling listed as a separate generation, so you do not get an “11th generation” repeated under a facelift name.
Because the generation count is 1, a buyer cannot “step up a generation” for more power, a different gearbox, or another drive layout. Production window arithmetic: from the first day of 1949 through the last day of 1955 is the entire run of this model in the data. The version 2.0 MT uses the same start and stop dates as the generation, so you are not choosing an early versus late factory spec by name — the sheet does not split 2.0 MT into two power figures.
What the generation does lock in for a purchase decision:
- Body type is Sedan only — not a second body to compare.
- Drive is RWD only.
- Gearbox is Manual with 4 gears only.
- Brakes are Drum front and Drum rear — no mixed list to pick from.
- Suspension is Dependent, leaf spring at both axles.
If you wanted AWD, Automatic, or a later turbo layout, those strings do not appear here. The “which version” answer is not a ladder of trims; it is a go / no-go on this one Sedan package.
BMW 340 specs: the only version named in the data
Exact name from the base (do not rename it): 2.0 MT.
| Version | hp | kW | rpm (power) | Nm | Displacement (cm³) | Fuel | Cylinders | Layout | Valves per cylinder | Boost | Gearbox | Gears | Drive |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 2.0 MT | 51 | 37 | 3750 | not measured | 1971 | Gasoline | 6 | Inline | 2 | No | Manual | 4 | RWD |
Engine feed: Carburetor. Engine location: not measured. Compression ratio: not measured. Bore and stroke: not measured. Extra fuel label (`toplivo_en`): not measured.
Power density (allowed arithmetic on given numbers): 51 hp ÷ 1971 cm³ = 25.9 hp per litre (51 / 1.971 L ≈ 25.88 hp/L). 37 kW ÷ 1.971 L ≈ 18.8 kW per litre.
There is no second row to subtract from. You cannot compute “the other engine has +X hp” because `modifikaciy` is 1. If two versions had shared the name 2.0 MT, they would be split by horsepower; they do not.
Engine: size, hp, kW, layout — buying implications
People search “bmw 340i engine hp”, “engine cc”, “engine size”, “horsepower”. For this BMW 340 sheet, the engine of 2.0 MT is:
- 1971 cm³ Gasoline, 6 cylinders, Inline, 2 valves per cylinder, boost No.
- Peak listed power: 51 hp / 37 kW at 3750 rpm.
- Torque (Nm) and torque rpm: not measured.
- Induction: Carburetor, not a second system.
What that means for a buyer who only has this row:
1. Displacement vs name. The version is called 2.0 MT. Displacement is 1971 cm³, not a round 2000 written in the sheet. Do not treat “2.0” as a second measured volume; 1971 is the measured figure. 2. Specific output is modest by arithmetic, not by storytelling. 25.9 hp/L with No boost is the whole power story. You are not buying a second, higher-hp calibration of the same name. 3. kW vs hp. 37 kW and 51 hp are both given; they describe the same 2.0 MT, not two engines. Search queries that ask for kW are answered by 37, not by converting in your head from a number we do not have. 4. No torque figure to rank drivability. “M340i horsepower and torque” style questions cannot be answered with Nm here: torque is not measured. Do not invent a torque curve. 5. Reliability, oil, engine code, engine bay, engine for sale. None of those fields exist in the data. They are not measured. A buying article that invented an engine code would be false.
Valves: 2 per cylinder × 6 cylinders = 12 valves total (arithmetic on given counts). That is the valve count you are buying; there is no 4-valve alternative in the list.
Performance, mpg, 0–100: what is not measured
For 2.0 MT:
- Acceleration 0–100: not measured
- Top speed: not measured
- Fuel consumption city: not measured
- Fuel consumption highway: not measured
- Combined consumption: not measured
- CO2: not measured
- Eco class: not measured
So: you cannot pick 2.0 MT because it is “quicker to 100” or “uses less fuel” than a sibling — there is no sibling, and those tests are not in the sheet. Search phrases like “bmw 340i specs 0 60” and “mpg” do not get numbers from this launch data. Saying the car has no such parameter would be wrong; the correct line is not measured.
The only energy-related hardware number that is measured besides power and displacement is the 70 L tank (next section). Without consumption, range is not measured (70 L ÷ unknown L/100 km is not a number we can publish).
Dimensions, weight, tank: what extra money cannot buy here
For 2.0 MT:
- Kerb weight: not measured
- Gross weight: not measured
- Ground clearance: not measured
- Wheel sizes: not measured
- Tank: 70 L
Weight per horsepower: not measured, because kerb mass is not measured. You cannot compute kg/hp and you cannot claim the car is “light for 51 hp.”
Tank vs missing mpg: 70 L is large relative to many later catalogue cars in a qualitative sense we will not quantify with invented fleet averages. Within this model, 70 L is the only tank figure — there is no 50 L vs 70 L choice.
Chassis you are buying with 2.0 MT:
- Front suspension: Dependent, leaf spring
- Rear suspension: Dependent, leaf spring
- Front brakes: Drum
- Rear brakes: Drum
No generation later in the data swaps in a different axle or brake type. A buyer comparing “which generation changed the brakes” gets the answer: none did, because there is only 1 generation.
Which version to choose
There is one named version: 2.0 MT. Choose it if the following measured package is the car you want. Walk away if you need a figure the sheet leaves not measured, or a layout the sheet does not list.
Take 2.0 MT when you want:
- BMW 340, 1 generation, Sedan, years 1949-01-01 … 1955-12-31.
- Gasoline 1971 cm³, 6 Inline, 2 valves per cylinder, boost No, Carburetor.
- 51 hp / 37 kW at 3750 rpm — about 25.9 hp/L and 18.8 kW/L.
- Manual 4, RWD.
- Tank 70 L.
- Dependent, leaf spring front and rear; Drum / Drum brakes.
Do not treat 2.0 MT as a stand-in for search terms it does not match:
- Not xDrive — drive is RWD, not another string.
- Not a second gearbox — only Manual, 4.
- Not a 2016–2025 340i horsepower table — those years are not in `start`/`stop`.
- Not a dual-power 2.0 MT (no 51 vs another hp under the same name).
- Not a torque comparison — Nm is not measured.
- Not a 0–100 or top-speed contest — both not measured.
- Not a weight or clearance contest — kerb, gross, clearance, wheels not measured.
What “extra money” would buy — arithmetic with one row: With one version, extra money cannot buy more hp, more gears, or another drive inside this model. The delta versus a non-existent second version is 0 hp, 0 kW, 0 cm³, 0 gears. Versus leaving the model entirely, you give up this unique measured set: 51 hp, 37 kW, 1971 cm³, 70 L, Sedan, RWD, Manual 4.
Generation vs generation: `pokoleniy` is 1. Nothing in the data shows a later generation adding boost, changing cylinder count, or moving off leaf springs. The buying question collapses to: is 2.0 MT the right car, not the right trim.
How to read a listing against this sheet: If a car is labelled BMW 340 and the seller’s spec does not match 2.0 MT as above (51 hp, 37 kW, 1971 cm³, Gasoline, Inline 6, Manual 4, RWD, 70 L tank, Sedan, 1949–1955 window), it is not this catalogue version. Do not merge it with 340i / F30 / M Sport / xDrive queries; those are other products, and this article has no prices and no for-sale data.
Short verdict: buy 2.0 MT as the only BMW 340 in the data — a 1949–1955 Sedan with 51 hp (37 kW) at 3750 rpm from a 1971 cm³ Gasoline Inline 6, No boost, Carburetor, Manual 4, RWD, 70 L tank — and treat 0–100, top speed, consumption, torque, weights, clearance, and wheels as not measured rather than as reasons to prefer a phantom second version.
