The sixth generation Familia (Mazda 323) included three-door hatchback, five-door fastback, and a four-door sedan variants, none of which share any body panels. The new five-door fastback version was called the Familia Astina in Japan and was sold as the 323F or 323 Astina elsewhere. The BF wagon (originally introduced in 1985) was carried over in facelifted form, although Ford marketed a wagon on the new platform as part of the North American Escort line.
The BG Familia was available with front- or all-wheel drive and a 1.3 L, 1.5 L, 1.6 L, or 1.8 L gas or 1.7 L diesel engine. Later, a turbocharged engine was added, especially developed for homologation purposes for the World Rally Championship, Group A category. The four-wheel drive models (including the turbocharged GT-X) were introduced in August 1989. In Japan, the SOHC 1.6 was only available coupled to four-wheel drive. With a carburettor, it offered 91 PS (67 kW), the same as the lower-spec 1.5, but with a somewhat larger torque curve. In Europe, only the 1.8 (in naturally aspirated, 106 PS form or either of the turbocharged variants) was offered with four-wheel-drive.
In North America, the 323 sedan became the Protegé, while the 323 hatchback kept its name. There, and in the Philippines, base (SE/DX), 4WD and top-line LX models were available. The 1990 base model has the SE name and uses the B8 1.8l SOHC engine that has 16 valves and hydraulic lifters. In 1991, the base model name was changed to "DX". 4WD models existed for the 1990 and 1991 model years, with the SOHC engine and rear disc brakes. The LX version of the Protegé included a BP 1.8l DOHC 16-valve engine 125 hp (93 kW). LX models also have power windows and door locks and 14 inch wheels. Vented front and solid rear disc brakes, larger front brakes, larger clutch, equal-length driveshafts, dual outlet muffler, body-color door handles and mirrors, fold-down rear center armrest, driver's vanity mirror, and larger stabilizer bars. A sunroof and 14 inch aluminum alloy wheels were options on LX models.
BG models that were assembled in New Zealand came with glass headlights instead of plastic, and a 240 km/h speedometer.
Production of the BG Familia mostly ended on 24 May 1994, although the 1.3-liter hatchback was kept in production until October 1996 as there was originally no 1.3 option in the following generation. In Australia, the BG model continued-to be sold until 1996 as a more affordable alternative to the newer BH model. In China, the BG model was sold as the Haima CA7130 and the CA7160. They were produced from 1998 to 2004. Power came from a 1.3 or 1.6-litre engine sourced from Toyota produced 86 and 83 horsepower respectively.
