Underneath the reworked body sits a Fiat 124 that was changed in roughly 800 places for Soviet conditions: raised ground clearance, thicker steel, drum rear brakes changed to a Soviet self-adjusting design, a stronger clutch, and a completely new overhead-camshaft engine designed by NAMI that Fiat itself never used.[1] Under the licensing deal, AvtoVAZ could not sell the car in Italy or compete against Fiat in other Western European markets it was already selling in, which is part of why the exported car was rebadged as a Lada rather than sold as a Fiat.
The manufacturer’s own specification table gives this car’s output under three different standards (Soviet GOST, European DIN, and American SAE) for the same engine, and they do not agree with each other (46, 44 and 48 kW respectively for the base 1.2). That is not a conflict to resolve; each is a real, differently-defined figure for the same physical engine, and DIN is recorded here as the most useful basis for comparing this car with everything else in the catalogue. The larger 21011 engine’s specification table gives no DIN figure at all, and the article’s prose separately quotes “67 hp” for it without saying whether that means metric PS or mechanical horsepower; rather than guess, this entry uses the table’s directly-stated GOST figure instead.
