The Citroën B10 is a "Torpedo" / "Conduite Intérieure" (saloon/sedan) from Citroën, built from 1924 to 1925, the vintage years, when coachbuilders still shaped most of what was sold. Under the bonnet: Petrol/gasoline: 1,452cc Straight-4.
Where it came from
The Citroën B10 is an automobile produced by Citroën at André Citroën's factory in central Paris between 1924 and 1925. The B10 was manufactured using modern mass production technologies which were applied by Citroën and still, at this point, by no other French auto-maker; although by now, across the river Rhine, Opel were also copying the assembly line approach (and also copying one of Citroën's models).
The Citroën B10 was in many respects similar to the manufacturer's B2 model. What marks it out as different is its use of an "all-steel" ("tout-acier") body. The B10 was the first European car maker to apply the pressed steel technologies, developed by Ambi-Budd, and which during the next fifteen years would transform the economics of automobile production across Europe.
Under the skin
Power comes from Petrol/gasoline: 1,452cc Straight-4. It weighs 810 kg. It shifts 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. The wheelbase is 2830 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
Its family tree is legible: it took over from the Citroën Type B2; its successor was the Citroën Type B12 / Citroën C4 & C6; assembly was at Parc André Citroën, Quai de Javel, Vaugirard, Paris, France. Its contemporaries in the catalogue — the Packard Eight, the Rolls-Royce Silver-Ghost landaulet, the Peugeot 5CV — show what else the money bought that year. Nearby in the Citroën catalogue sit the Citroën K and the Citroën 2CV.
What it costs now
MotorJury scores cars on the United States complaint and recall record, and the Citroën B10 has none: too old, too rare, or never sold there. Its value today is a collector's question, decided by provenance and condition rather than by a class average.
