The Amilcar C4 is a lightsporting car designed for road use made between 1922 and 1929 by the French Amilcar company. The C4 is one of three models introduced by Amilcar in 1922; the others were the CC and the CS, both of which were significantly different from the C4, although they did use the same chassis. The C4 was touted as a more economical and usable vehicle than the other more sporty models. The C4, publicly introduced at the Paris Salon, was offered in three models: the highest-produced was the "Torpedo", which was offered in full Torpedo style or slightly toned down ; both were available configured with 2, 3 or 4 seats. Also available were a sedan, and a commercial version. The variety of styles available provided a wide selection to the public; this fact combined with the models' low initial cost and moderate operating costs caused the C4 to be fairly popular during its eight-year production run.
Description
The C4 chassis is a lengthened version of that of the Amilcar CC model. Coachwork for this vehicle was fabricated by subcontractors and delivered to the Amilcar for final assembly. Power for the C4 was provided by the same unit used in the CS, a 1003 cc four-cylinder engine with a bore, a stroke, a magneto ignition AND Solex carburetor; it was rated at 22 KW at 2800 rpm. The vehicle transmission provided three speeds, with power being sent to the rear wheels. The suspension used semi-elliptic leaf springs in both the front and rear as well as fitted friction type dampers. Brakes were only provided on the rear wheels. The drum-type brakes were 220 mm diameter, and were operated by foot-pedal, which differed from the hand-lever operation employed in both the CS and CC automobiles. Standard equipment was ample for the period, consisting of a speedometer with recording odometer, an ammeter, and the dashboard incorporating lighting. The horn initially was a classical trumpet with rubber bulb; this was replaced by an electric horn beginning in 1925.
