Datsun Sedan

1956 - 112 Series

The Datsun 112 was only in production for a total of six months, from December 1955 through until May 1956. The body was essentially the same as the previous 110 model, but a few significant changes were made.   


For reasons unknown, Nissan went straight from the Datsun 110 to the 112, completely missing the 111 designation.
The front mounted indicators, placed either side of the grille opening on the Datsun 110, were removed for the 112 model. These were replaced with a pair of bullet shaped indicators that now sit on top of the front guards, back towards the windscreen. At the back of the car the oval stop lights from the 110 have been replaced with a pair of round stop lights.  

There is now a DATSUN badge on the side of the car, just under the new bullet indicators. The rear badge remains the same, but there is a redesigned DATSUN badge at the front.
 The front features a new grille design, which is slightly wider than the 110, with two horizontal rows of eight rectangular slots, with a large horizontal bar in between.
The dashboard has been completely redesigned. The old 110 model had an instrument binacle located in the centre of the dash, the new 112 has a redesigned instrument panel that is now located directly in front of the driver. Mechanically the 112 was exactly the same as the 110. It continued to use the 860cc D-10 side valve engine.
 The Datsun 112 won the Second Mainichi Industrial Design Award in 1956 for its "novel design, maneuverability, and comfortable interior".

Model Variations

Datsun 122 Pickup

A range of small commercial vehicles based on the Datsun 112 sedan were also produced at the same time. This range of vehicles, called the 122 series, included a pickup truck and a light van. More information about these vehicles can be found in the Datsun 122 section.  


Datsun ?? 112

I found this photo of what appears to be a two door version of the 112 on a Japanese language website a few years back. There was a 2 door version of the previous 110 model but it was a convertible only, but this is a hard top. It does not show up in any of our extensive sales brochure and literature collection. It may be a prototype that never entered production, or even just someone playing with Photoshop. It remains a mystery.


Datsun W112

 The Datsun W112 was the station wagon version of the Datsun 112 sedan. It was introduced at the same time as the sedan and features a two piece cargo door, with a framed glass section that opens upwards, and a lower section that folds downwards.   


Datsun M112

 The M112 is an ambulance / medical specialty vehicle based on the W112 wagon.
