The Porter Cab (KECA53) was introduced in March 1969. It was a small, cabover pickup truck on a 1,835 mm (72.2 in) wheelbase, equipped with a live rear axle and a 23 PS (17 kW) at 5500 rpm, 359 cc water-cooled, two-stroke two-cylinder. This, the CC, was Mazda’s first two-stroke engine. Top speed was 90 km/h (56 mph). In 1970 new doors were developed, with sliding windows were exchanged for roll-down items, incorporating a quarter window. A ventilation vent was also added to the front. Like the Porter, the Porter Cab received the Chantez-derived AA engine in April 1973, which offered 30 PS (22 kW) at 6000 rpm, five less than in the Chantez. In January 1975, the Porter Cab too was lightly modified to fit the new larger license plates – hitherto, kei cars had carried smaller license plates than regular cars (230 mm (9.1 in) x 125 mm (4.9 in) rather than 330 x 165 mm). The Porter Cab, with its peculiar cowlings around the headlights carried an instantly recognizable “surprised” appearance. In April 1976 the Porter Cab also received an engine which met the new, tougher 1975 emissions regulations and the model code PC3A. The only color available was changed too, from light green to white. Like the Porter before it, the Porter Cab was labelled E360 in export markets. This very cute little commercial vehicle was restored many years ago and remains is in museum condition.
