Mazda MX-3 four-seat hatchback
The Mazda MX-3 was a four-seat hatchback produced from September 1991 to 1998. It was based on the EC platform. 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.
The MX-3 was available with an I4 engine, and the GS with a V6 engine. It is notable for having one of the lowest displacement V6 engines ever fitted to a production vehicle with its 1.8 L V6.
The MX-3 came with three engine options: a 1.5 L I4 (only found in the Autozam AZ-3), a 1.6 L I4 and a 1.8 L V6. The 1.6 L was available in two versions, an 88 hp (66 kW) SOHC/16-valve B6-ME unit which powered 1992 and 1993 models, or a 106 hp (79 kW) DOHC/16-valve B6-D unit which was found in 1994 and later models. The Japanese market DOHC/16-valve B5-ZE produced 115 hp (86 kW) and the most powerful DOHC 24-valve V6 K8-DE produced 135 hp (101 kW) and 130 hp in North American models. All were available with a 5-speed manual or an optional 4-speed automatic transmission, depending upon the market.
The V6 MX-3 had a top speed of approximately 212 km/h (132 mph). The MX-3 GS could accelerate from 0-60 mph (97 km/h) in 8.4 seconds, and could travel a quarter mile in 16.4 seconds. With a turning rate of 0.89 g (8.7 m/sē), its handling capabilities were one of 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, very long lasting, and hold a high torque across the RPM range. These engines used 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 7000 rpm redline, and a 7800 rpm fuel cutoff. It is rumored that Porsche designers helped to create the K series engine.[citation needed]
The MX-3 used Mazda's proprietary Twin-Trapezoidal Link (TTL) for the rear suspension. It passively allowed the rear wheels to turn slightly in order to enhance handling. It has been used on a range of Mazda vehicles, providing a smooth ride, yet delivering responsive handling while minimizing body lean.
