In 1963 only, the first Swedish-assembled 1800's were, in fact, officially named P1800S. This was only in 1963, and only for the first Swedish cars that were essentially similar to the Jensen-built P1800's. From 1964 onward the name was simply 1800S, until 1970 when fuel injection changed the suffix to "E" for einsprutning. The P1800 name originally meant "P" for passenger car and "1800" for the engine size, and the "S" was added to indicate Swedish assembly. But for some odd reason--probably marketing--the 1800 name remained even after the engine size increased to 2000 cc in 1968.
