Overview

When Japan engineering meets UK craftsmanship, the result is one of the most compelling matchups in the classic car world. The 1990 Mazda Eunos Cosmo 20B Type S and 2006 Jaguar XK X150 Coupe embody their respective national automotive traditions while competing in the same arena. The 2006 Jaguar XK X150 Coupe holds a clear advantage in raw power with 385 hp compared to 300 hp, a 85-horsepower difference that shapes the driving experience. Under the hood, the contrast is notable: the Mazda Eunos Cosmo uses a Triple-Rotor Wankel (20B-REW) displacing 1,962 cc, while the Jaguar XK relies on a V8 DOHC with 5,000 cc. In the sprint to 60 mph, the 2006 Jaguar XK X150 Coupe edges ahead at 5.0 seconds versus 5.0 seconds. Rarity plays a significant role here — with only 8,875 units built, the 1990 Mazda Eunos Cosmo 20B Type S is considerably scarcer than the Jaguar XK's 54,000 examples. From a collectibility standpoint, the 1990 Mazda Eunos Cosmo 20B Type S rates higher among enthusiasts and auction houses.
