Start with what the Datsun Type 13 is: a phaeton, roadster, sedan, van, truck with 747 cc DAT SV I4, built from 1934 to 1935, when streamlining and independent suspension were arriving together. What it meant takes a little longer.
The background
The Datsun Type 13 was a small car produced by Nissan Motor Co., Ltd. Introduced in July 1934, it remained in production until March 1935 after its replacement, the Type 14, was introduced in February 1935. The Type 13 was basically similar to the earlier 1933 Type 12, but was more stylish in appearance. For the first time, a truck version was also available; the Datsun Type 13T.
The engineering
The engine is 747 cc DAT SV I4. On the scales it comes to 400 kg. Drive goes through a 3-speed manual. The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Where it sits
In the Datsun line-up the Datsun Type 13 has a clear place: it replaced the Datsun Type 12; it handed the line to the Datsun Type 14; the factory was Yanase Motor/Nihon Jidosha Corp.. The cars a buyer would have weighed it against include the Chevrolet Suburban, the Bugatti Type 57, the Fiat 527. Its Datsun stablemates include the 280Zx and the 310.
Owning one today
There is no federal ownership record for the Datsun Type 13 — it predates the complaint database or was never sold in the United States — so MotorJury publishes no running-cost figure for it. For a car of this age the price is set by the collector market and the condition of the individual example, not by a formula.
