The Mazda MX-3 is a four-seat Kammback coupé first introduced at the Geneva Motor Show in March 1991. The MX-3 was marketed as the Mazda MX-3 Precidia in Canada, the Eunos 30X in Australia, and as the Eunos Presso, Autozam AZ-3 and Mazda AZ-3 in Japan.The MX-3 is quite popular for modification because of the range of performance engines which can be transplanted, such as the KL-ZE.
First introduced at Geneva Auto Show in March 1991, production continued to 1998. The MX-3's platform is called the EC platform, and shares much with the BG platform of the contemporary Familia/323/Protegé. The first model year available for most markets, including North America where it went on sale in September 1991, was 1992. Originally available with a single-cam 1.6-liter inline-four or the twin-cam V6, a few more engines were available as development continued. In the summer of 1991, the Autozam AZ-3 was added to the Japanese market lineup. It was known by two names;"Autozam" was meant to be Mazda's more youthful brand, so it combined a somewhat lower price with a sportier (but smaller) twin-cam four of 1.5 liters, and also sold as the Eunos Presso, a companion, affordable sports car to the Eunos Roadster.
The small displacement V6 was offered so that it would comply with Japanese government regulations concerning exterior dimensions and engine displacement; Japanese buyers were liable for taxes for vehicles exceeding the regulations which would affect sales. Japanese buyers who were willing to pay the tax for larger vehicles were now given a choice of the FC series Mazda RX-7 and the JC series Mazda Cosmo.
In January 1994, a DOHC version of the familiar B6 engine, the B6D, replaced the previous version. This provided a useful power increase but conversely also made the considerably more expensive V6 version less desirable. Sales of the V6 in the United States market came to an end after the 1994 model year, although they continued in Canada, Japan and many other export markets. While called K8-DE in North American specs, Japanese and other markets received an engine called the K8-ZE. Aside from emissions equipment and varying power claims due to myriad ratings methods, the differences are negligible.
The V6 MX-3 has a factory claimed top speed of 202 km/h (126 mph) (in European trim). The US-spec MX-3 GS can accelerate from 0 to 60 mph (97 km/h) in 8.4 seconds, and can travel a quarter mile in 16.4 seconds. With a turning rate of 0.89 g (8.7 m/s²), its handling capabilities were among the best in its class.
The V6 engine was impressive for the time, belonging to the Mazda K-series, which were used in a range of Mazda vehicles. These engines were designed to be smooth and hold a high torque across the rpm range. These engines use a variable length intake manifold (VLIM), in order to provide optimal torque using intake resonance. Mazda called their system on the MX-3 the "Variable Resonance Induction System" (VRIS). This engine had a 7,000 rpm redline, and a 7,800 rpm fuel cutoff. It has been rumored that Porsche designers assisted in the creation of the K series engine.
For the rear suspension of the MX-3, Mazda used its proprietary Twin-Trapezoidal Link (TTL) technology. This is designed to provide a smooth ride while delivering responsive handling and minimizing body lean. It achieves this by passively allowing the rear wheels to turn slightly to more closely approach their optimal angle during steering maneuvers. In this way, TTL technology delivers some of the benefits associated with active four-wheel steering systems while being lighter and mechanically less complicated. Twin-Trapezoidal Link technology has been used on a range of other Mazda vehicles before and since the MX-3.

In 1993, Mazda Canada offered a limited special edition model of its Mazda MX-3 GS to celebrate the company's 25th year in Canada. At the same time, Mazda USA offered a similar model to a special edition as well. Only a total of 2,000 special edition models were supposedly made. The special edition MX-3 featured the V6 engine, leather interior (including seats, steering wheel and shift knob), heated seats (Canada only), and custom Enkei manufactured 15 inch alloy wheels. Most special edition models came in the color "raspberry metallic"; however, there was also "blaze" red, "brilliant" black, and "laguna" blue.
In 1993, Mazda Europe produced 100 Mazda MX-3 V6 SEs. These had a leather and suede interior, and all had the clear white body color. There were also a limited number of Mazda MX-3 V6 Equipes, with "sparkle green metallic" or "noble" green exteriors.
The MX-3 is becoming a rare car, so modifications for it can be difficult to find unless one knows where to look, since it has not been sold in North America since 1997. Since the MX-3 has two engine classes, I4 and V6, many of the engine performance modifications are dependent upon what platform is installed.
There is now a decent range of body modifications for the MX-3 along with performance brakes and suspension. Most extensive modification must be entirely custom fabricated due to limited availability.
Swapping of the four-cylinder RS engines is slightly more complicated than the V6 GS mainly due to ECU, wiring harness, and MAF combinations as well as motor mounts. The V6 swaps require specific ECU, intake manifold, and VAF sensor combinations, but there are far fewer variables to deal with. Many improvements can be made after the engine swap and during the engine tuning process to find the best combination of engine peripherals.
The most common engine swap for MX-3 GS owners with the V6 engine is a 2.5 L V6, either a North American-spec KL-DE 168 hp (125 kW), found most commonly in the 1993-1997 Ford Probe GT, the 1993-1997 Mazda MX-6 LS, or the 1993-2002 Mazda 626 LX or ES, and the Japanese-spec KL-ZE 200 hp (149 kW), found in such vehicles as the Efini MS-8, Xedos 9, and Eunos 800. A 2.0 L V6 KF-ZE is also available, but this swap is quite difficult due to the unavailability of required components. For this reason, this particular engine swap is not often attempted. The GS, apart from the engine has dual tip exhaust, a tighter steering ratio, four disc brakes and front and rear spoiler.
The MX-3 has made several appearances in movies and TV shows, including The Italian Job(twice), Dumb and Dumber, I Robot (with a kit on, parked in an alley), The Fast and the Furious, 2 Fast 2 Furious (John Walsh’s MX-3), Analyze That, Cellular, Postal, John Doe and Session 9.
