The history of the Japanese automobile industry is inextricably linked with models that were once considered innovative, but today have become collector's rarities. Nissan Datsun 100A is exactly the kind of car that is often confused with the more famous 210 series, but it has its own unique destiny and engineering philosophy. This compact hatchback was a response to the growing demand for fuel-efficient city vehicles in the late 1970s.
If you look at this car, you will immediately notice its futuristic design for its time, which was ahead of many Western analogues. Compactness and practicality were the main trump cards of this model, allowing it to easily maneuver in dense city traffic. Many enthusiasts are still looking for examples in good condition to restore them to factory shine.
History of creation and place in the Datsun line
Development Nissan Datsun 100A began in conditions of fierce competition in the domestic and foreign markets. The company's engineers understood that the mass consumer needed not just a cheap car, but also a safe and modern one. That is why the model received front-wheel drive, which was rare for Japanese cars of that time in its class.
Key Feature body structures became modular, which made it easy to adapt the chassis to different modifications. Unlike previous 510 or 610 series models, the emphasis here has been on efficient use of interior space. You could see how the engineers squeezed the maximum out of every cubic centimeter of volume.
However, it is worth noting that this model had a short production period, making it especially valuable to collectors. The 100A was released in limited quantities and quickly gave way to the more advanced 210 series, which inherited many of its technical solutions, but received a modified design.
- 🚗 The first prototype was presented in 1977, arousing huge interest from the press.
- 🏭 Factories in Japan and the UK (in partnership with British Leyland) were engaged in assembly.
- ⚡ OHC series engines became the basis for future Datsun power units.
Technical characteristics and power units
Under the hood Nissan Datsun 100A hidden engines were compact but powerful enough for their class. The most common versions were 1.0 and 1.2 liters. These engines were highly reliable and easy to maintain, which is critical for cars intended for everyday use.
The transmission was offered both as a classic manual gearbox and as an automatic hydromechanical one for more comfortable driving. Torque transmitted to the front wheels through a simple but effective drive system. This provided excellent stability on slippery roads.
The chassis has been designed with passenger comfort in mind. Independent front suspension with wishbones and torsion bars ensured a smooth ride even on rough roads. The rear suspension is also noteworthy as it minimizes body roll in corners.
- 🔧 Engine capacity: 988 cc. cm or 1171 cc. cm depending on the configuration.
- 📉 Fuel consumption: about 6-7 liters per 100 km in the combined cycle.
- 🚀 Maximum speed: up to 145 km/h for versions with a 1.2-liter engine.
⚠️ Warning: The original carburetors on these models often require careful adjustment due to changes in fuel quality over the past decades. Be sure to check the condition of the jets before starting the engine.

Exterior design and interior design
Appearance Nissan Datsun 100A is a striking example of the evolution of Japanese design. Its rounded shape, large headlights and compact silhouette made it recognizable on the road. Sedans and hatchbacks had their own characteristics in the roofline, but the overall style remained the same.
The interior was surprisingly spacious for a car of this size. Ergonomics The driver's seat was thought out to the smallest detail: all controls were within reach. The instrument panel had a classic layout with large dials that were easy to read even in the twilight.
The finishing materials were simple but durable. The plastic and fabric used in the interior have stood the test of time, although it is now difficult to find them in perfect condition. You may notice how some interior elements are faded by the sun or lost their appearance due to wear and tear.
- 💺 Seats with adjustable backrest provided comfort on long trips.
- 🎛️ The steering wheel had a small diameter for easy control.
- 🧳 The luggage compartment in the hatchback increased with the rear seats folded.
When looking for interior parts, pay attention to parts from Datsun 210 models, as many interior elements have been unified and fit in size.
Features of operation and maintenance
Owning a classic car requires a special approach to maintenance. For Nissan Datsun 100A This is especially true as original spare parts are becoming increasingly difficult to find. It is necessary to carefully monitor the condition of rubber seals and hoses, which lose elasticity over time.
The cooling system often becomes a problem for older cars. Regularly checking the antifreeze level and the condition of the radiator is what you need to pay attention to first. An overheated engine can lead to costly cylinder head repairs.
The brake system also requires regular maintenance. Drum brakes at the rear and disc brakes at the front provide sufficient performance, but the pads and drums need to be checked every 10 thousand kilometers. Pad wear may be invisible visually, but noticeable in the quality of braking.
Here is a list of basic actions that need to be performed regularly:
- 🛢️ Change engine oil every 5000 km or every six months.
- 🔋 Checking the condition of the battery and terminals before the start of the season.
- 🔩 Inspect the suspension for backlash and wear of silent blocks.
☑️ Checklist before seasonal launch
What to do if the engine does not start?
First of all, check the spark plug wires and the presence of a spark. Often the problem lies in a wet carburetor or old gasoline. Try draining the remaining fuel and adding fresh fuel.
Comparison with analogues of that time
In the compact car market of the late 70s Nissan Datsun 100A competed with models such as the Toyota Starlet and Mazda 121. Each of these cars had its own advantages and disadvantages, but it was the Datsun that stood out for its front-wheel drive and modern design.
Compared to the Toyota, the Nissan model offered a more comfortable suspension, which was important for family trips. However, Toyota was famous for its reliability and simplicity of design, which made it more popular in some regions. Choosing between them often depended on buyer preference and parts availability.
The table below will help you visually compare the main characteristics of these models:
| Characteristics | Nissan Datsun 100A | Toyota Starlet (P30) | Mazda 121 (FA) |
|---|---|---|---|
| Drive | Front | Front | Front |
| Engine capacity (max) | 1.2 l | 1.3 l | 1.1 l |
| Body type | Hatchback/Sedan | Hatchback | Hatchback |
| Years of manufacture | 1977–1978 | 1978–1984 | 1975–1981 |
Although the Nissan Datsun 100A did not last long on the market, it laid the foundation for the successful 210 series and set the direction for the development of compact front-wheel drive cars in Japan.
Tips for restoration and tuning
