Second generation B-Series
Mazda Rotary Pickup
The 1966 B1500/Proceed introduced in October 1965 utilized a similar 1484 cc OHV I4 motor as its forerunner, with minor changes to the chamber head and valves and the utilization of a downdraft carburetor rather than the sidedraft unit utilized on the models sold somewhere in the range of 1961 and 1965. The UA motor currently delivered 72 PS (53 kW) at 5200 rpm. The undercarriage was presently called the “BUD61”; it was longer than its forerunner and got new bodywork of a squarer plan, and four headlights. In January 1971, a 1600 cc model with the case code BNA61 was presented. This had 95 PS SAE in worldwide markets; US pamphlets didn’t indicate its capacity yield and European shippers asserted 75 PS (55 kW) DIN. In Japan, a base 100 PS (74 kW) (SAE net) was asserted; the model was promoted in Japan as the “GT-Truck”.
