Adler 2.5-litre

Adler 2.5-litre: which version to buy

The Adler 2.5-litre catalogue lists one generation and one named version: 2.5 MT. If the question is which Adler 2.5-litre to choose, the data leave no second engine, no second gearbox, no restyle, and no later generation to trade against. 2.5 MT is a Cabrio, Gasoline, 6 Inline cylinders, 2494 cm³, 57 hp (43 kW), Manual 4, RWD, top speed 125 km/h, built from 1937-01-01 to 1940-12-31.

The Adler 2.5-litre catalogue lists one generation and one named version: 2.5 MT. If the question is which Adler 2.5-litre to choose, the data leave no second engine, no second gearbox, no restyle, and no later generation to trade against. 2.5 MT is a Cabrio, Gasoline, 6 Inline cylinders, 2494 cm³, 57 hp (43 kW), Manual 4, RWD, top speed 125 km/h, built from 1937-01-01 to 1940-12-31. Torque, 0–100, mpg, weights, tank, and clearance are not measured. There is no extra version that “buys” more power or more gears; the arithmetic below is the whole choice.

Which Adler 2.5 litre version to buy

2.5 MT is the only row. Specific output from the given figures is 57 hp ÷ 2494 cm³ × 1000 = 22.85 hp per litre, or 43 kW ÷ 2494 cm³ × 1000 = 17.24 kW per litre. Peak rpm for power is not measured, so those ratios cannot be tied to a crank speed. Torque (Nm) is not measured, so there is no Nm-per-litre figure and no way to rank 2.5 MT as “torquey” versus “peaky” against a sibling that does not exist.

Gearbox and drive do not split the range: 2.5 MT is Manual with 4 gears and RWD. There is no Automatic, no AWD, no FWD, and no extra ratio count in the data. Boost is not measured. Fuel system on 2.5 MT is Carburetor. Engine position is Front, longitudinal. Body on this generation is Cabrio only.

Because there is only one named version, “which version” is not a comparison of two catalogue lines. It is a check that 2.5 MT matches the use case that the measured numbers actually support: a Cabrio with 57 hp, 125 km/h, RWD, Manual 4. Anything else (weight, economy, 0–100, tank, wheels) is not measured and cannot be used as a buying argument.

Generations compared: what 1 generation changed

The Adler 2.5-litre has 1 generation (`1 generation`), 1937-01-01–1940-12-31, body Cabrio, 1 version. There is no 2nd generation in the data, so there is no year-to-year jump in hp, litres, gears, or drive to subtract. Restyling is not listed as a separate generation and must not be counted as one: the reader would otherwise see a generation that the data do not contain.

Span of the listed dates: from 1937-01-01 to 1940-12-31 is four calendar years of the same 2.5 MT specification. Power stays 57 hp / 43 kW; displacement stays 2494; cylinders stay 6 Inline; layout stays Front, longitudinal; gearbox stays Manual 4; drive stays RWD; top speed stays 125 km/h. No later generation adds hp, so there is no “extra money for a later engine” calculation. No earlier generation subtracts hp, so there is no “buy the last year for more power” calculation either.

If the choice is generation rather than version, the data still point to the same car: 1 generation, Cabrio, 2.5 MT.

Engine and specs: the only catalogue line

Version names must stay exactly as in the data.

2.5 MT also has: power 43 kW; power rpm not measured; torque rpm not measured; valves per cylinder not measured; Carburetor; compression not measured; bore × stroke not measured; engine Front, longitudinal.

Arithmetic on that single row: 57 hp at 2494 cm³ is 22.85 hp/l; 43 kW at 2494 cm³ is 17.24 kW/l. 6 cylinders on 2494 cm³ is 2494 ÷ 6 = 415.67 cm³ per cylinder (displacement share only; bore and stroke remain not measured). 57 hp across 6 cylinders is 9.5 hp per cylinder if power were split evenly — a ratio from the given counts, not a measured dyno split.

There is no second Adler 2.5-litre engine in the table to subtract from 57 hp or from 2494 cm³. A buyer looking for a higher-hp 2.5 MT or a smaller-displacement 2.5 MT will not find it in this model’s data.

Performance, mpg, and what the numbers do not buy

2.5 MT top speed is 125 km/h. 0–100 is not measured. City consumption is not measured. Highway consumption is not measured. Combined consumption is not measured. CO2 is not measured. Eco class is not measured. Fuel grade is not measured.

Without 0–100, there is no seconds-per-hp ranking and no way to say 2.5 MT is quicker than another version. Without consumption, there is no mpg comparison and no “thirstier engine” trade-off. The only performance number that can be used in a choice is 125 km/h on 2.5 MT. Relative to 57 hp, that is 125 ÷ 57 = 2.19 km/h per hp (a ratio of two measured figures, not a test of drag or gearing). Relative to 2494 cm³, 125 km/h is 50.12 km/h per litre of displacement.

If a buyer needs a documented 0–100 or a documented mpg figure to decide, this catalogue does not supply one for 2.5 MT. Those fields are not measured, not “typical of the class.”

Dimensions, weight, tank: what is not measured

For 2.5 MT: kerb weight not measured; gross weight not measured; ground clearance not measured; tank not measured; wheels not measured; front suspension not measured; rear suspension not measured; front brakes not measured; rear brakes not measured.

Weight per horsepower cannot be calculated: both kerb and gross mass are not measured, so there is no kg/hp and no payload figure. Tank range cannot be calculated: tank volume and consumption are both not measured. Clearance and wheel size cannot be used to prefer one version, because there is only 2.5 MT and those fields are empty.

A choice that depends on kerb weight, towing-related gross mass, winter clearance, or wheel fitment is not supported by this model’s numbers.

Problems, reliability, and what the extra money buys

Problems and reliability are not measured in the supplied data: there is no fault count, no service interval, and no generation that later “fixed” a listed defect. Do not infer durability from the Carburetor, Manual, or RWD labels; those are equipment names, not reliability scores.

“What the extra money buys” cannot be priced: prices are not in the data. Within the mechanical list, extra money also cannot buy a second Adler 2.5-litre version, because modifikaciy is 1. There is no +hp pack, no extra gear, no extra driven axle, and no later generation with a higher maks_skorost than 125. The difference between “this 2.5 MT” and “another 2.5 MT” in the same catalogue is zero horsepower, zero centimetres cubed, zero gears, and zero km/h.

If the buyer’s real question is Adler 2.5 litre versus a different model entirely, that comparison is outside this dataset. Inside it, the only consistent choice is 2.5 MT, 1 generation, Cabrio, 1937-01-01–1940-12-31, 57 hp, 43 kW, 2494 cm³, Gasoline, 6 Inline, Front, longitudinal, Carburetor, Manual 4, RWD, 125 km/h, with torque, 0–100, mpg, weights, tank, clearance, and wheels not measured.
