1961 Ford Econoline, and the 1961 Chevrolet Greenbrier. Second generation (1966–1973) The redesigned Sambar debuted in January 1966 with revised styling and a truck variant. The second generation is nicknamed the "baban" Sambar. The Sambar continued to use the 356 cc EK31 engine, but now in the iteration used in the Subaru 360 since July 1964. A raised roof for extended headroom was added to the options list in 1968. Starting with the 1970 model year, the engine was accessed from outside the vehicle, and the front doors were conventionally hinged. To enhance safety a full padded dash pad was introduced, sharing the dashboard panel from the new R–2. Along with the facelift, the engine was also updated (EK33) and now produced . The styling was also revised, adding a faux front grille to create a more modern appearance as well as bringing the corporate look of the all new compact Subaru Leone. The Sambar saw new competitors, the Mazda Porter in 1968, and the Honda Vamos in 1970. Third generation (1973–1982) The third generation appeared 10 February 1973, this one nicknamed the "Gōriki (Herculean strength)" Sambar due to an advertising campaign at the time. The first series still carried a two-stroke two-cylinder 356 cc engine but by now water-cooled. Maximum power is at 5500 rpm. The engine code was EK34, the truck received the K71 model code while the van was called K81. As of February 1976, the engine was upgraded to the EK21 four-stroke water-cooled version introduced in the Rex to reduce emissions. Claimed maximum power remained the same, but at a much higher engine speed (7500 rpm) and with considerably lower torque figures than the earlier two-stroke type. This model saw the introduction of an electric window washer pump to improve driver visibility. Because of regulations changes, only three months later the engine was again upgraded with a 490 cc displacement (EK22) engine of a similar layout for the Sambar 5 (K75 truck, K76 panel van, K85 van). This was naturally sold as the Subaru 500 in export markets. This was in turn soon replaced by a full 550 cc (EK23) model, the K77/87 of March 1977. In export, the Sambar 550 was known as the Subaru 600. This model saw the introduction of a sliding side door added on both sides (although a version without the driver's side door remained available), with a full "B" pillar
