240 Landmarks Top ＞ Passenger Cars, Part 1 ＞ Toyopet SA 　Toyopet SA Equipped with the type S engine, the SA had Japan's first domestically designed backbone type Y-frame, and 4-wheel independent suspension. A single pipe ran longitudinally down the center of the vehicle as a spine to act as the frame, passing through a propeller shaft in the center. At the front, the spine branched into 2, forming a Y-shape, between which the engine was mounted. The rear end was fixed to a differential case, allowing a swinging up and down movement centered on hinge joints at the left and right ends of the differential case to transmit power to the rear axle. The 4-wheel independent suspension, which created a new type of action generated by transverse leaf springs, was responsible for excellent ride comfort unmatched by any small car. The SA I seated 4 passengers, and the SA II was a 2-door sedan that seated 5. The gearshift was provided next to the steering wheel and operated by means of a link type remote control. The low center of gravity of the SA due to its backbone structure gave it excellent stability over 80 km/h.
