The Mazda Roadpacer is a full-size sedan that was manufactured by Mazda in Japan between April 1975 and 1977, although the last car was not sold until 1979. It was based on the Australian Holden HJ and HX series Premier. [1] Premiers were shipped to Japan without engines or transmissions, and Mazda fitted a 1.3-liter 13B Wankel engine into the bay. It was the first large Japanese car to meet the 1975 emissions standards, although that was a short-lived distinction because the Nissan President followed suit a month later. In October 1975, the engine was revised to meet the 1976 emissions standards, at which time the car gained the "AP" (Anti-Pollution) moniker. [2] The Roadpacer has the distinction of being the only General Motors product ever fitted for production with a rotary engine.
The engine produced 135 PS (99 kW; 133 hp) but just 186 N⋅m (137 lb⋅ft) of torque, at a peaky 4,000 rpm, meaning the Roadpacer performed rather poorly as it weighed 1,575 kg (3,472 lb). [3] The Roadpacer was introduced to compete with large Japanese flagship sedans Toyota Century, Nissan President, Isuzu Statesman de Ville, and the Mitsubishi Debonair. The Roadpacer's platform was the shorter version of the one used by Isuzu for the Statesman de Ville. Negotiations began in April 1973; the collaboration with Holden was agreed to shortly before Mazda entered into an engineering partnership with Ford. [4] This materialized before the Roadpacer was able to go on sale but did not impact the car's introduction.
The 13B produced less power than the Red series motors that powered the equivalent Holdens, and significantly less torque, meaning performance was restrained with a 165 km/h (103 mph) top speed, poor acceleration and terrible fuel consumption from the overworked engine. [3] Contemporary reports suggest 9 mpg (26 L per 100 km). [3] The three-speed automatic transmission with a steering column shift lever was sourced from Jatco and was shared with the LA series Mazda Luce.
While the Holden HJ Premier itself was well equipped, Mazda decided to add more. Gadgets of note include a central locking system that activated when the car hit 10 km/h (6.2 mph), a chime system that activated at 90 km/h (56 mph), a dictation system and a stereo able to be controlled from both front and back seats. The interior was offered with a choice of velour upholstered bucket seats and a center console for the front passengers or a split front bench seat, seating either five or six people accordingly. The Roadpacer was built only for the Japanese market, and certain aspects concerning its lack of speed become evident once its realized that urban two-way streets are usually zoned at 40 km/h (25 mph) or less, [5] as mentioned in the article Speed limits in Japan . Another negative quality was that although the car was very large on the outside, the rear seat was not particularly large; Holden offered the longer wheelbase Statesman for this. [4]
The price was also considered high at ¥3.8 million yen (US$13,000) in 1975 ($73,610 in 2023 dollars [6] ). This was about twice the price of a contemporary Mazda Cosmo or Mazda Luce and the installation of numerous luxury amenities would be introduced again in 1990 on the Eunos Cosmo. Originally intended as transport for high-ranking government officials, the car was sold in the wake of the first fuel crisis and was not a commercial success. Production ceased in late 1977 after only 800 units built and 799 cars sold, with sales of leftover stock continuing into 1979. Most were originally sold to government departments and were later crushed, meaning Roadpacers are rare nowadays;[ citation needed ] their counterpart model, the Holden Premier is a popular collectors' car in Australia.
One example can be found on display in the Transport World Motor Museum in Invercargill, New Zealand.

Holden, formerly known as General Motors-Holden, was an Australian subsidiary company of General Motors. Founded in Adelaide, South Australia, it was an automobile manufacturer, importer, and exporter that sold cars under its own marque in Australia. In its last three years, it switched entirely to importing cars. It was headquartered in Port Melbourne, with major industrial operations in the states of South Australia and Victoria. The 164-year-old company ceased trading at the end of 2020.

The final generation of Cosmo served as Mazda's flagship vehicle in Japan, being sold as the Eunos Cosmo through its luxury Eunos division in Japan.
The Mazda Luce is an executive car that was produced by Mazda in Japan from 1966 until 1991. It was widely exported as the Mazda 929 from 1973 to 1991 as Mazda's largest sedan. Later generations were installed with luxury items and interiors as the Luce became the flagship offering. The Luce was replaced by the Sentia in 1991 which was also exported under the 929 nameplate.

The third generation of compact cars designed by GM, the J-body marked the introduction of front-wheel drive for its compact model lines, simultaneously replacing the rear-wheel drive H-body and the European U-body platforms, the latter being a stretched version of the original rear-wheel drive T-body. The J-body was marketed as a world car, with GM brands selling versions of the platform in North America, Europe, Australia, and Japan; in markets outside of North America, the model line was packaged as a mid-size car.

The Holden Kingswood is a full-size car that was developed and manufactured in Australia by Holden, from the beginning of the HK series in 1968 through to the conclusion of the WB series in 1985. Prior to 1968, the full-size Holden range of family cars comprised the Holden Standard, the Holden Special, and Holden Premier models. Initially, the HK range of models included the basic Holden Belmont, the Kingswood, and the luxury-oriented Holden Premier, all of which were manufactured in a choice of sedan and station wagon bodies. Commercial variants were offered in three types: coupé utility, panel van, and later from 1971, a heavy-duty Holden One Tonner cab chassis. The utility (ute) version was originally marketed in both Belmont and Kingswood configurations. However, after the Belmont name was deleted from commercials at the end of HQ in late 1974, the base model commercials were sold only with the "Holden" badge.
The Isuzu Gemini is a subcompact car produced by the Japanese automaker Isuzu from 1974 until 2000. The same basic product was built and/or sold under several other names, sometimes by other General Motors brands, in various markets around the world. While the first generation was of a rear-wheel drive design, later versions were all front-wheel-drive, and the last two generations were no more than badge-engineered Honda Domani until the name was retired in 2000.
The Isuzu Florian is an intermediate class car manufactured by Isuzu Motors Ltd. in Japan from November 1967 until 1983. The Florian's body remained essentially the same through its unusually long life cycle, being afforded only two moderate facelifts. The Isuzu Florian was originally presented as the Ghia Isuzu 117 Sedan at the 1966 Tokyo Motor Show and shared its complete chassis with the closely related Isuzu 117 Coupé. Originally available only with a 1.6 liter gasoline inline-four engine producing 84 PS (62 kW) at 5200 rpm, a 1.8 liter version was later added as was a diesel option, first seen in 1977.

The Mazda Grand Familia is an automobile which was produced by Mazda in Japan from 1971 to 1978. It was sold as the Mazda 808 in some export markets including Asia, Australia, and New Zealand, and as the Mazda 818 in many others - this was mostly due to Peugeot having trademarked three-digit numbers with a middle zero in many markets. The body style configurations offered were a two-door coupé, a four-door sedan, and a five-door station wagon. The Grand Familia offered only inline four cylinder engines. The largely identical rotary-powered versions were marketed as the Mazda Savanna in Japan, with export markets taking this model as the Mazda RX-3.
Amati was a proposed luxury brand announced by Mazda in August 1991 as part of Mazda's expansion plan with the launch of the Autozam, Eunos, and ɛ̃fini marques in hopes of becoming Japan's 3rd largest automaker. It was scheduled to launch in 1994 as a competitor to fellow Japanese luxury car marques Acura, Infiniti and Lexus as well as American and European luxury vehicles. However, when the Japanese economy collapsed in early 1992 Mazda faced a liquidity shortage and was unable to complete development of the brand. Mazda announced the cancellation of the Amati brand in October 1992 and the completed vehicles were sold under Mazda's existing brand names.
The Mazda Parkway is a minibus that was based on the Mazda Titan platform, and was manufactured at the Hiroshima Factory exclusively for the Japanese market. In 1974, the Parkway was installed with the 13B rotary engine and well as a 2000cc gasoline type "VA" and the diesel 2500cc type "XA". It also offered a novel transmission approach added to the manual transmission installed, called a sub transmission to cope with the load carrying requirements, and a fluid coupling to preventing engine stalling, knocking and oscillation. The rotary-powered minibus was called the Parkway Rotary 26, and could accommodate 26 passengers, even though it weighed 2,835 kg (6,250 lb), and could achieve a maximum speed of 120 km/h (75 mph). It was introduced July 22, 1974 and the rotary engine was replaced with a more conventional diesel engine in 1977.
