The 929 is Mazda's entry model to the luxury line of cars that was first seen in 1973. It replaced the Mazda Luce nameplate as Mazda's expert version and eventually became the flagship sedan of Mazda. The Mazda 929 was first released as a coupe, sedan, and station wagon that were all powered by a 1.8 L (1769cc) inline 4 Mazda 1800 engine with an output of only 83 hp (61 kW) and 101 ft.-lb torque(137 Nm).

Two years later, a 2.0 L (1970cc) engine that can produce 103 hp (76 kW) and 123 ft-lb (167 Nm) from a 2 barrel carburetor became an optional engine. Another additional engine that became an option for the 929 was the 13B rotary engine that can produce a 127 hp (93 kW) and 138 ft-lb or 188 Nm of torque. In 1977, the proven more efficient 2.0 L I4, producing 90 hp (66 kW) with a single-barrel carb engine was added. The first year of the 80s gave the 929 the final addition that was the 2.2 L Diesel engine rated at 66 hp (49 kW) and 104 ft-lb or 142 Nm of torque.

The next generation 929 was introduced in 1981. A new HB platform was added featuring a large front-engine rear wheel drive sedan. As part of the 929, the Mazda Comso was released in the market but after four years, Mazda was already withdrawn the model.

The improvement to the 929 was seen in 1986 with a new HC platform and a more powerful 3.0 L V6 engine. It went on production up to 1991. Other engines include: 2.0 L FE I4, FI, at 116 hp, 2.2 L F2 I4, 1 barrel, 115 hp, and the 2.2 L F2 I4, FI, 127 hp. During the 90s, the Mazda 929 sat on the HD platform but was renamed as the Efini MS-9.
