fenders blended into the fuel tank valence. The trunk on the town sedan, town coupe and five-passenger convertible coupe was integral with the body. The vision of the driver was improved by 30 percent as a result of the elimination of the outside visor and the construction of a 12 degree sloping windshield and corner posts. There was a large ventilator on top of the cowl and none on the sides. All separate body moldings were eliminated. A three spoke steering wheel enabled an unobstructed view of the instrument cluster when in the straight ahead position. The right side of the instrument panel was occupied by a "locker." Engine horsepower increased to 115. The deepening Great Depression caused sales plummet to 2,700. 355C (1933) In 1933, the aesthetics of all Cadillacs were updated with a new, corporate "streamlined" appearance shared with all GM cars for that year due to GM's Art and Color Studio headed by Harley Earl.The bumpers on the 1933 Series 355C were sectioned, with plain ends and a three bar center. The grille was made V-shaped and blended into the painted (chrome optional) radiator shell. The radiator cap disappeared under the hood on the right side (same side as the oil level gauge). The fender tie bar, after a year's absence was sectioned and the center section was hidden behind the grille. Six horizontal doors replaced the vertical hood doors. Skirts were added to the front and rear fenders. The most significant change in body detail was the introduction of "No Draft Individually Controlled Ventilation" (ICV) or pivoting vent windows in the front doors and the rear quarter or rear door windows. In early production the front door window had to be lowered to disengage the channel at its front edge from the vent window to allow the vent window to pivot. In later production the sealing channel was attached to the door frame rather than to the window glass so that the vent window could be operated independently of the window glass. Windshield and rear quarter windows were made stationary. The vent windows were an optional feature on all GM vehicles beginning in 1933. Absence of a windshield operating mechanism on the closed car allowed room to conceal the wiper motor behind the headboard. The cowl ventilator was baffled and drained in such a way as to be rainproof. Chassis changes were few and minor in
