The Ford car was thoroughly updated in 1941, in preparation for a time of unpredictability surrounding World War II. The 1941 design would continue in an aborted 1942 model year and would be restarted in 1946 and produced until 1948 when the more modern 1949 Fords were ready. During the initial year of this car, it evolved considerably. The front fenders came in three pieces, the theory being that small damage could be replaced easily. During the year, it evolved into two pieces with the lower front and back sections being joined. The hood risers changed, the early ones being the same as 1940 Fords, changing during the year to the better later version. The 1941 Convertible had no rear side windows, the only side windows being in the doors; in 1942, quarter windows were added so the rear occupants could see out.
Five different coil/distributor arrangements were used during 1941, causing confusion for mechanics. Other variations were: two different positions for the generator, and three for the cooling fan — front of the crankshaft, front of the generator (rare) and on a bracket. This is thought to be the first Ford to offer an oil filter. The two interior heaters were a "Southwind" gasoline burner, which had the advantage of keeping one warm in winter at drive-in movies, and a more ordinary hot-water type. Both had window defrosters. It had an excellent radio, which could consume the battery in about two hours. Electric windshield wipers were available in addition to the vacuum-powered wipers. Three different convertible power top mechanisms and two different header bar latching systems were used. Rear suspensions sometimes had a sway bar, most did not. It had excellent brakes for the time, and the best handling of an ordinary car at the time. It was a very transitional car.
