Manufactured from October 1992 to 1994, the AZ-1 was noted for its gullwing doors. Power came from the same Suzuki-sourced 657 cc turbocharged engine used by the Mazda Carol that produced 64 PS (47 kW) at 6500 rpm and 85 N·m (63 lb·ft) at 4000 rpm.
Suzuki produced its own badge engineered version named the Suzuki Cara (PG6SS).
The proposal for the AZ-1 goes as far back as 1985 when Suzuki created the Suzuki RS/1 as a midship sports car project for volume production. Suzuki went as far to design the car for the Tokyo Motor Show more than just a design exercise, they designed the car to be functional with a front/rear weight distribution of 45:55 powered by a 1.3 liter G13A engine from the Cultus.
This was followed up by the Tatsumi Fukunaga designed RS/3, unveiled for the 1987 Tokyo Motor Show, retaining many of its design features of the predecessor but many of its design features were worked on to meet Japanese safety regulations as well as being a practical sports car. Unfortunately, the project was abandoned in favor of the roadster project they had been working on, named later as the Cappuccino.
Mazda's design team, led by Toshiko Hirai, who was also responsible for the MX-5, took over the design project, despite having a limited budget and capacity.
The redesigned cars, constructed in tube frame with floors and bulkheads constructed from aluminium honeycomb, clad in three different bodystyles constructed in fibreglass. The cars were constructed around the Kei car regulation of the time (maximum length 126 inches (3,200 mm), maximum engine capacity 550 cc), until this was changed for the following March, hence its model name, AZ-550 Sports.
First introduced at the 1989 Tokyo Motor Show as the AZ-550 with three versions. First one of these, the Type A was a red sports car with pop-up headlights, front air vent and a distinctive Ferrari Testarossa inspired side strakes but most distinctive of all design features were the gull-wing doors.
Type B, themed as "High-tuned pure sports", was inspired by the trends in the tuning industry and in current concept car design, featuring greenhouse pyramid roof without a rearward sweep to the C-pillar. It had a racing car inspired interior, unlike Type A, it was aiming for the rough and spartan look and was the only model that a more conventional forward door hinging. It featured a pair of bulging headlamps and incorporated dual mufflers.
Type C, had a more distinctive body design as it was inspired by Mazda's Group C sports prototype racers, incorporating its signature colour scheme of blue on white and its number it bore at the 24 hours of Le Mans. Featuring a bigger air intake than the former two, venting to the forward-positioned radiator and exits it along the front rim of the cowl. There are many design cues typical to an endurance racer such as the wing mirror and BBS style brake-cooling wheel discs. Compared to the Type B, this version was far more spartan in comparison.
As the cars were well received by the visiting public and the motoring press, Mazda executives decided on production of the car. Although Type C was the better received of the three, it was the Type A which was given the greenlight by executives as they believed that it would be the one most commercially accepted by the buying public. The Type A would only receive a minor design alteration prior to production, as the pop-up headlights were dropped in favour of fixed units, purely for structural rigidity reasons. The front air vent was the other design alteration made to the car prior to production.
Nonetheless, the car took three years to get into production as the engineering team changed the car's internal skeleton frame to steel to allow for further rigidity. The dashboard design was also changed, to a less futuristic but still sporting look.
Much of the development work was carried out in the United Kingdom despite the fact that the car was never intended for sale outside Japan.
 Rear viewThe car was made available to the buying public on September 1992, with two color options, Siberia Blue and Classic Red. Both colors came with Venetian Gray lower panels. Each car was sold through the Autozam dealer network in Japan.
Unfortunately by the time car came into production, the recession in Japan had just come into force. Selling for 1,498 million ¥ (the equivalent of $12,400), it was slightly less than a Eunos Roadster, but marginally higher than its competitor, the Honda Beat selling at 1,388 million ¥ and the Suzuki Cappuccino at 1,458 million ¥, the AZ-1 was considered to be both too expensive and too cramped for a kei car. The car failed to sell within its target of 800 per month, in the midst of an economic recession. Production of the car ended after the following year, but Mazda had plenty of stock to sell off.
With the total production of 4,392 over a year, plus 531 for the Cara version (mentioned later in the article) to 28,010 to the Cappuccinoand 33,600 for the Beat, both with production reaching into the latter half of the 1990s, this makes the AZ-1 the rarest of the kei sports cars.
In a bid to shift unsold stock, Mazda made an effort to produce special versions. First to come was the Type L option, featuring an enhanced audio system including a sub-woofer in the boot. There were no exterior changes made to the car.
Mazda also introduced the Mazdaspeed version to showcase the parts that were available for the car, the A-spec, the body kit features an enhanced bonnet, front spoiler and rear wing. Unlike the production version, the car came in an all-red or blue body colour. It also came with a host of options including shock absorbers with sports spring sets, strut bars for the front and rear, mechanical LSD, enhanced air filter and a stainless steel and ceramic muffler. It also came with its own brand of alloy wheels as opposed to the production's steel wheels.
For 1994, There was also the M2 1015 by M2 Incorporated. The most distinguishing part of the car is the front fog lights incorporated into the bonnet, and the all-new front bumper and rear spoiler. The car came in three different colours: white, black and silver. Like the Mazdaspeed version, the car was painted entirely in a single color.
Fifty were to be produced and sold by the M2 dealer, but they only managed to sell about half of its stock. The dealer covered their losses by selling the body parts individually. A genuine "M2 1015" can be identified by the rear emblem stating the version name.
Other versions Although the M2 1015 was the only version sold by the dealer, M2 also created other versions purely for show purposes and to test market their cars.
M2 1014 was a one-off off road inspired car built for the 1993 Tokyo Motor Show with design cues coming from the Lamborghini Cheetah. M2 1015A is a rally inspired featuring auxiliaries of a rally car including a pair of spotlights detached on the bottom of the bonnet. The M2 1015B incorporated a detachable top roof, instead of being constructed of glass, it was constructed in plastic.
In 1996, renowned tuning company and rotary specialist, RE Amemiya produced another one off example for the Tokyo Auto Salon, called the GReddy VI-AZ1 (named after its long-term partner, the sixth incarnation of their partnership project car), it was influenced by the AZ-550 Type-C but longer and wider, incorporating a 20B three rotor Wankel engine, mounted longitudinally. The only part of the car that has traces of the original AZ-1 is the gullwing door. The car uses suspension parts produced by Bilstein that can be found in a Porsche 962 and the brakes from a Ferrari F40. The car was rebuilt again in 2000 with the car now resprayed to white, also a wing replacing the ducktail spoiler of the original, also replaced was the tire with a slightly wider version, brakes are replaced by those from a Ferrari F50. The car have since then been sold on to a private owner in Japan.
There was also a one-off version built in 1996 named Abarth Scorpione commissioned by Shiro Kosaka, a renowned collector of Abarth sports cars, with numerous design cues from its genuine and rare namesake. The car is entirely rebodied at a cost of one million yen for the body alone, plus another million yen for painting and fitting. The genuine car in fact features conventional opening doors.
