BMW 321: Which Version Should You Buy?
The BMW 321 catalogue contains only one generation and one version, so there is no higher-powered engine, alternative gearbox, different body style, or later generation to compare. The sole choice is the 2.0 MT, a Sedan 2-doors with a 1,971 cc Gasoline engine, 46 hp, a 4-speed Manual gearbox, and RWD. It produces approximately 23.3 hp per litre.

Because no price data is available, it is not possible to say what extra money would buy or whether one example represents better value than another.
BMW 321 generations compared
The catalogue records 1 generation of the BMW 321. The 1 generation ran from 1937-01-01 to 1941-04-30 and was offered as a Sedan 2-doors. It contains 1 version, the 2.0 MT, so there are no generations to compare and no recorded restyling to assess separately.
The version record for 2.0 MT spans 1937-01-01 to 1950-12-31, while the generation itself is dated from 1937-01-01 to 1941-04-30. These are the catalogue dates as supplied. They do not create another generation or an additional version.
BMW 321 engine and specs
The only BMW 321 engine in the catalogue is the 2.0 MT unit. Its displacement is 1,971 cc, and it develops 46 hp (34 kW) at 3,750 rpm. That equals approximately 23.3 hp per litre or 17.3 kW per litre.
The engine uses Gasoline, has 6 cylinders in an Inline layout, and has 2 valves per cylinder. Boost is listed as No, the fuel system is Carburetor, and the compression ratio is 6. Bore and stroke are 66 × 96. Torque and the engine-speed figure for torque are not measured.
| Version | Power | Torque | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 2.0 MT | 46 hp (34 kW) at 3,750 rpm | not measured | 1,971 cc | Gasoline | 6 | Inline | No | 4-speed Manual | RWD |
There is no Automatic, AWD, diesel, boosted, or alternative-displacement BMW 321 in the supplied catalogue. Searches such as “BMW 321i,” “BMW 321d,” or “BMW 321 coupe” therefore do not identify additional versions in these data. The sole recorded model is the BMW 321 2.0 MT in Sedan 2-doors form.
Performance, top speed, and mpg
The BMW 321 2.0 MT has a maximum speed of 109 km/h. Acceleration from 0 to 100 km/h is not measured.
City fuel consumption is not measured, highway fuel consumption is not measured, and combined fuel consumption is not measured. Consequently, an mpg figure cannot be calculated from the supplied data. CO₂ emissions and ecological class are also not measured.
| Version | 0–100 km/h | Top speed | City consumption | Highway consumption | Combined consumption | CO₂ |
|---|---|---|---|---|---|---|
| 2.0 MT | not measured | 109 km/h | not measured | not measured | not measured | not measured |
The lack of acceleration and economy measurements prevents a meaningful performance-versus-efficiency comparison. The only numerical performance conclusion available is that the 2.0 MT combines 46 hp with a recorded maximum speed of 109 km/h.
BMW 321 dimensions, weight, and chassis
Kerb weight is not measured, and gross weight is not measured. Ground clearance and wheel sizes are likewise not measured. Because kerb weight is unavailable, weight per horsepower cannot be calculated for the 2.0 MT.
Fuel-tank capacity is 50 litres. Both the front and rear suspension are listed as Dependent, leaf spring. The front brakes are Drum, and the rear brakes are also Drum.
| Version | Kerb weight | Gross weight | Ground clearance | Tank | Wheel sizes |
|---|---|---|---|---|---|
| 2.0 MT | not measured | not measured | not measured | 50 litres | not measured |
No catalogue dimensions are supplied, so a numerical comparison of length, width, height, wheelbase, or cargo capacity cannot be made.
BMW 321 problems and reliability data
Problems and reliability are not measured in the supplied data. There are no numerical records for failure rates, maintenance costs, component life, or repair frequency. The catalogue therefore cannot support a claim that one BMW 321 version, production year, engine, or transmission is more reliable than another.
For the same reason, the specifications should not be used to invent an ownership-cost ranking. The 2.0 MT is the only version listed, and no price, sales-listing, or condition data is available.
Which BMW 321 version should you buy?
Choose the 2.0 MT if you specifically want the BMW 321 represented in this catalogue: it is the only available specification. It provides a 1,971 cc Gasoline engine with 46 hp, approximately 23.3 hp per litre, a 4-speed Manual gearbox, RWD, and a maximum speed of 109 km/h. It is paired with the Sedan 2-doors body and a 50-litre tank.
There is no second version against which to trade power, fuel use, transmission type, or drivetrain. There is also no later generation that adds a different body or engine. In practical buying terms, the decision is therefore not between BMW 321 specifications but between individual examples of the same 2.0 MT specification. Price, condition, history, mileage, and availability are outside the supplied data and cannot be compared here.
