The 1989 Mazda RX-7, specifically the 1.3L 150 HP (112 KW) S4 model, marked a significant step forward in the evolution of this iconic sports car. It was the first generation of the RX-7 to receive a major redesign, moving away from the angular lines of its predecessor to a sleeker, more aerodynamic profile. This change was driven by a move to a new platform, offering a longer wheelbase and wider track, along with improved suspension geometry. Under the hood, the rotary engine received a significant upgrade with the introduction of the 13B-T Turbo II engine. This powerful 1.3-liter twin-rotor engine delivered a respectable 150 horsepower (112 kW) and 146 lb-ft of torque, making the S4 a truly enjoyable driving experience. The increased power was complemented by the addition of fuel injection, turbocharging, and an intercooler, further enhancing performance and drivability. The S4 also featured a revised interior with improved ergonomics and a more driver-focused cockpit. The 1989 RX-7 S4, with its iconic design, potent engine, and refined handling, established itself as a formidable competitor in the sports car market. Its combination of practicality and performance made it an appealing choice for both enthusiasts and everyday drivers alike. The S4's design and engineering helped solidify the RX-7's reputation as a symbol of Japanese sports car excellence. Although the S4 model represented a technological leap forward, it carried over the renowned handling and agility that characterized the RX-7 lineage. The S4's advanced suspension design, featuring a MacPherson strut front and a multilink rear setup, allowed for a well-balanced ride and precise handling, making the car a joy to drive on both winding roads and open highways. The S4's design and features cemented its legacy as a cult classic, and it continues to captivate enthusiasts and collectors today. The 1989 RX-7 S4 remains a testament to Mazda's dedication to building high-performance sports cars that offer both excitement and practicality.
