Generations: what changed between generations (and what did not)

There is no second generation in the data, so there is no later generation that added power, gears, or a different body. A 1968 car and a 1977 car in this catalogue are the same named version: 1.0 MT. Production span is 10 years and 364 days (1967-01-01 through 1977-12-31). That length is calendar arithmetic on the given start and stop dates; it is not a second specification.

1 generation ran from 1967-01-01 to 1977-12-31. Body: Sedan. Versions in this generation: 11.0 MT, itself dated 1967-01-01 to 1977-12-31.

There is no second generation in the data, so there is no later generation that added power, gears, or a different body. A 1968 car and a 1977 car in this catalogue are the same named version: 1.0 MT. Production span is 10 years and 364 days (1967-01-01 through 1977-12-31). That length is calendar arithmetic on the given start and stop dates; it is not a second specification.

If you hoped a later generation would bring more gears, a different drive, or a measured 0–100 figure, this dataset does not list that generation. The buy decision is not “which generation” — it is whether 1.0 MT matches the numbers you need.

Specs table: the only version

VersionhpNmDisplacement (cc)FuelCylindersLayoutBoostGearboxDrive
1.0 MT115188999Gasoline2RotorNoManualFWD

Same row, restated so a cut paragraph still stands: 1.0 MT is 115 hp (85 kW) at 5500 rpm, 188 Nm at 4500 rpm, 999 cc, Gasoline, 2 cylinders in Rotor layout, No boost, Carburetor, engine Front, transverse, Manual with 3 gears, FWD.

Valves per cylinder in the data for 1.0 MT: 2. Compression ratio: not measured. Bore and stroke: not measured.

Brakes on 1.0 MT: front Disc, rear Disc. Front suspension: Independent, spring. Rear suspension: Independent, spring.

Engine: power per litre and what 115 hp means on 999 cc

1.0 MT puts 115 hp through 999 cc. Specific output is 115 ÷ 0.999 ≈ 115.1 hp per litre (equivalently 115 ÷ 999 × 1000). That is arithmetic on the catalogue displacement and power, not a second engine.

Torque: 188 Nm at 4500 rpm. Peak power is 1000 rpm later than peak torque (5500 − 4500). The catalogue does not give a torque curve beyond those two points.

85 kW is the same power as 115 hp in the data, not a second tune. There is no 1.0 MT at a different horsepower in this generation, so you do not split two identically named versions by power (there is only one 1.0 MT, and it is 115 hp).

Fuel type: Gasoline. Feed: Carburetor. Boost: No. You cannot choose a boosted 1.0 MT or a non-Gasoline 1.0 MT in this list.

Cylinder count and layout are 2 and Rotor as labelled. Do not read that as a different bank layout than the data states: the English label is Rotor.

Gearbox and drive: 3-speed Manual, FWD — no alternative row

1.0 MT is Manual, 3 gears, FWD. There is no automatic row and no other drive row. “Which gearbox” and “which drive” are not open choices in this catalogue; they are properties of the only version.

If a buyer wants more than 3 gears, this dataset does not offer another NSU RO 80 version with a higher gear count. If a buyer wants anything other than FWD, the same applies.

Performance and economy: mpg, 0–100, top speed

Top speed of 1.0 MT: 180 (the data unit for this field is the catalogue’s max-speed value as given). That is the only measured performance number.

0–100 for 1.0 MT: not measured. City fuel use: not measured. Highway fuel use: not measured. Combined fuel use: not measured. CO2: not measured. Eco class: not measured. Fuel grade: not measured.

You cannot rank 1.0 MT against another RO 80 on 0–100 or mpg, because those fields are not measured and there is no second version to differ from. A search for mpg on this model should read that absence as absence, not as a hidden consumption figure.

Kerb mass 1251 kg and 115 hp give 1251 ÷ 115 ≈ 10.88 kg per hp for 1.0 MT. That ratio is only a way to read the two measured numbers together. It is not a substitute for the missing 0–100 time.

Dimensions and weight: kerb, clearance, tank, wheels

1.0 MT kerb weight: 1251. Gross vehicle weight: not measured. Ground clearance: 120. Fuel tank: not measured. Wheel size: not measured.

What you can use when choosing: you have a kerb mass and a clearance. What you cannot use: tank size, tyre size, and a gross-weight limit — all not measured. Two cars of this version in the catalogue still share 1251 kerb and 120 clearance; the data does not split them by year inside 1 generation.

Reliability and problems: what this catalogue can and cannot say

This catalogue does not list failure rates, seal life, or service intervals. Reliability and problems are therefore not measured here. The mechanical facts that are measured and that a buyer still has to live with on 1.0 MT are: Rotor 2-cylinder layout, Carburetor, No boost, 3-speed Manual, FWD, disc brakes labelled Disc front and rear, Independent, spring at both ends.

Those are configuration facts, not a reliability verdict. Do not treat them as a scored “problems” ranking; the data has no such score.

Which version to choose

Choose 1.0 MT — it is the only named version.

What the numbers of 1.0 MT actually give you:

What extra money cannot buy in this list (there is no second row): more hp, more Nm, another displacement, another gearbox, another drive, a measured 0–100, a measured mpg, a measured tank, measured wheels, or a measured gross weight.

1.0 MT versus a hypothetical later generation: 0 extra generations, 0 extra versions, 0 hp difference, 0 Nm difference. The generation did not “change” to another generation in the data; start and stop of both the generation and the version are 1967-01-011977-12-31.

If the question is “1968 Audi NSU RO 80 or later RO 80?”, this catalogue answers with the same version name both times: 1.0 MT, 115 hp, 188 Nm, 999 cc, 3-speed Manual, FWD. Year inside that window is not a separate specification here.

If the question is “which engine — Wankel search terms versus this table?”, the English labels on 1.0 MT are Gasoline, 2 cylinders, Rotor. That is the engine row to buy; there is no other engine row.

Bottom line: buy 1.0 MT if 115 hp, 188 Nm, 999 cc, Sedan, FWD, 3-speed Manual, kerb 1251, clearance 120, and top speed 180 are the package you want, and accept that 0–100, mpg, tank, wheels, gross weight, compression, bore/stroke, fuel grade, CO2, and eco class are not measured. There is no second NSU RO 80 version in this dataset to spend “extra” on.
