Japanese domestic market it was marketed as a van, intended for commercial usage. Due to the introduction of the Toyota Hilux pickup truck, the previously offered Mark II pickup was discontinued. The engines offered began with the 1.7-litre inline-four and grew in displacement with increased standard equipment utilizing an overhead camshaft design. The top level GSS hardtop coupe, which was offered as an alternative to the Crown Coupe, offered a twin-cam design with dual carburetors for 1972–1974, upgrading to electronic fuel injection starting in 1975. The X10 through 13 are sedans, 16- and 17-series numbers were reserved for vans, 20 through 23 for coupés, and 26 through 29 for wagons. The only exception to this scheme is the 18R-U–engined RX15, introduced in June 1976, which received the same chassis code whether fitted in the hardtop or the sedan. Engine choices included: I4 1,707 cc 6R (RX10/RX16V/RX20/RX26: ) I4 1,808 cc 16R (RX11/RX17V/RX21/RX27) I4 1,968 cc 18R (RX12/RX22/RX28) I4 1,968 cc 18R-G DOHC (RX22 GSS) I4 1,968 cc 18R-U (RX15, low emissions version) I6 1,988 cc M (MX10/MX20/MX27) I6 2,253 cc 2M (MX12/MX22/MX28, export only) I6 2,563 cc 4M (MX13/MX23/MX29, export only) In August 1973, there were minor changes and updates. The basic trim package wagon was offered with a five-speed manual transmission. Electronic fuel injection was introduced on the two-litre four-cylinder (18R) engine to increase power and lower fuel emissions. The four-cylinder 1,707 cc 6R engine was replaced by the 1,808 cc 16R. The 1.8 was discontinued in October 1975, leaving only two-litre engines of four or six cylinders in the Japanese market. Even after the introduction of the next Mark II, production of the second generation continued through November 1976. North America The Crown line of cars was no longer marketed in North America due to poor sales. This left a gap in Toyota's North American line up, offering only smaller compact cars. The second-generation Mark II fortunately increased in size. The Mark II would be one of the few sensible options for families transitioning from larger American Detroit cars in the midst of the oil crisis. In 1974 it was marketed in the U.S. as a fully loaded car with few added options. Standard features included a six-cylinder SOHC engine, four-speed manual transmission, front disc brakes, heater defroster, and bucket seats. Some available options were stereo cassette player, power steering, air conditioning, and a three-speed automatic transmission. North
