Description
The Mazda Xedos 9 2.5 S 4WS was the most technically advanced and dynamically sophisticated version of Mazda’s flagship executive saloon of the 1990s. Building on the refinement of the standard 2.5-litre V6 model, the 2.5 S 4WS introduced an electronically controlled four-wheel-steering system that transformed its handling, stability and agility. Offered mainly in Japan and in very limited numbers in certain export markets, it stood at the top of the Xedos 9 range as a showcase of Mazda’s engineering ambitions. It combined elegant styling, luxury features and one of Mazda’s best V6 engines with chassis technology more commonly associated with high-end European and Japanese performance cars.
Power came from Mazda’s KL-series 2497 cc 24-valve V6, producing around 170 horsepower depending on market. This engine was renowned for its silky smoothness, free-revving character and refined delivery. It gave the Xedos 9 strong mid-range response, quiet acceleration and the kind of mechanical polish that allowed it to compete convincingly with six-cylinder offerings from BMW, Mercedes and Lexus. The 2.5 S retained the choice of a five-speed manual or, more commonly, a four-speed automatic, with the automatic emphasising the car’s luxury-focused personality. Even with the added weight of the 4WS system, the V6 provided effortless performance well suited to relaxed executive motoring.
The defining feature of the 2.5 S 4WS was its electronically controlled four-wheel-steering system. At lower speeds the rear wheels turned slightly in the opposite direction to the fronts, reducing the turning radius and making the car surprisingly manoeuvrable in tight city environments. At higher speeds the rear wheels turned in the same direction as the fronts, enhancing stability and giving the Xedos 9 a planted, confident feel during motorway lane changes and fast sweeping bends. The result was an unusually composed and agile large saloon, capable of feeling both supple and surprisingly responsive. Combined with fully independent suspension — MacPherson struts at the front and a sophisticated multi-link layout at the rear — the 2.5 S 4WS delivered one of the smoothest and most secure driving experiences Mazda had ever engineered.
Styling remained identical to the rest of the Xedos 9 lineup, characterised by flowing, aerodynamic surfaces and a minimalist, elegant profile. Mazda intentionally kept the design restrained, emphasising subtle luxury rather than sporty aggression. Slim headlights, a clean front grille and gentle curvature along the body created a calm and dignified presence. The 2.5 S typically featured discreet badges and higher-spec alloy wheels, but its sophistication came from proportion and purity rather than decoration. The body was engineered for low wind noise, contributing further to the model’s refined driving characteristics.
Inside, the Xedos 9 2.5 S 4WS provided a genuinely premium cabin environment. The layout was symmetrical and uncluttered, with soft-touch surfaces, high-quality plastics and optional leather upholstery. The seats were wide and deeply cushioned, offering excellent long-distance comfort. Mazda paid attention to detail with wood-tone trim, tight panel fit and generous sound insulation. Equipment levels were high for the era, typically including climate control, high-grade audio, electric windows and mirrors, remote locking and refinements such as heated seats or upgraded upholstery on some versions. Rear passengers benefited from excellent legroom due to the long wheelbase, making the car well suited to chauffeur-style use as well as private ownership.
On the road the Mazda Xedos 9 2.5 S 4WS delivered a driving experience defined by calmness, precision and a sense of controlled sophistication. The V6 engine flowed smoothly and quietly through its power band, while the chassis absorbed surface imperfections with gentle composure. The four-wheel-steering system added an extra layer of stability at motorway speeds and a surprising flick of agility at lower speeds. The result was a large luxury saloon that felt secure and poised in all conditions, with road manners more refined than many of its contemporaries. It was not designed for sharp sporting performance, but for serene, confidence-inspiring travel.
The Xedos 9 2.5 S 4WS represented the peak of Mazda’s 1990s luxury engineering, combining one of their finest V6 powertrains with advanced chassis technology and a discreetly premium design philosophy. It helped demonstrate Mazda’s ability to build a genuine executive-class car with innovation and refinement rather than overt branding or extravagance.
Today the 2.5 S 4WS is extremely rare and highly regarded among enthusiasts who appreciate its technical sophistication, smooth V6 performance and elegant styling. As one of the most advanced and luxurious saloons Mazda ever produced, it remains a standout example of the brand’s ambition during a unique chapter in its history.
