the star of the salmson stand at the 31st paris motor show in october 1937 could have been the salmson s4-e. the car's four-cylinder 2312 cc power unit extended the s4 range upwards, into the 13cv category. in fact, the car was placed at the far end of the stand without fanfare and without any accompanying publicity campaign, so that many visitors to the show likely missed it completely.
