The Mitsuoka Himiko Concept 1.5 is a unique and relatively obscure roadster produced by the Japanese coachbuilder Mitsuoka Motors. Introduced in 2018, the Himiko is notable for its retro styling heavily inspired by the classic MG TD, a British roadster from the 1950s. However, beneath the vintage exterior lies a thoroughly modern Mazda-based platform. Mitsuoka specializes in building low-volume, often highly stylized vehicles, and the Himiko is a prime example of their approach – blending nostalgic aesthetics with contemporary mechanicals. The vehicle was primarily intended for the Japanese domestic market, where there is a strong appreciation for classic British car designs, but a limited number were exported.
The Mitsuoka Himiko Concept 1.5
The Himiko Concept 1.5 represents Mitsuoka’s attempt to capture the spirit of classic British roadsters for a modern audience. Mitsuoka doesn’t design vehicles from the ground up; instead, they modify existing platforms, often from Japanese manufacturers, and clothe them in bespoke bodywork. The Himiko utilizes the chassis and mechanical components of the Mazda MX-5 (Miata), but its exterior is entirely different, evoking the look of a 1950s MG TD. This approach allows Mitsuoka to offer a distinctive vehicle with the reliability and performance of a modern car.
Engine & Performance
Powering the Mitsuoka Himiko Concept 1.5 is Mazda’s SKYACTIV-G 1.5-liter inline four-cylinder gasoline engine. This engine produces 131 horsepower at 7000 rpm and 150 Nm (110.63 lb.-ft.) of torque at 4800 rpm. The engine features direct injection, a double overhead camshaft (DOHC) valvetrain with variable valve timing (VVT), and a high compression ratio of 13:1. These features contribute to both performance and fuel efficiency. The engine is mated to a six-speed automatic transmission, delivering power to the front wheels. The vehicle’s weight-to-power ratio is 9.1 kg/Hp, and its weight-to-torque ratio is 7.9 kg/Nm, translating to a respectable power-to-weight ratio for a small roadster. The engine displacement is 1496 cm3 (91.29 cu. in.), and the engine delivers 87.6 horsepower per liter.
Design & Features
The most striking aspect of the Mitsuoka Himiko is its exterior design. The bodywork is a faithful recreation of the MG TD’s classic lines, complete with prominent fenders, a rounded grille, and a split windshield. However, the Himiko is a two-seater cabriolet with a more modern soft top mechanism. The interior, while retaining a classic aesthetic, incorporates modern amenities such as air conditioning, power windows, and a contemporary infotainment system. The vehicle’s dimensions are 4580 mm (180.31 in.) in length, 1740 mm (68.5 in.) in width, and 1235 mm (48.62 in.) in height, with a wheelbase of 2910 mm (114.57 in.). The curb weight ranges from 1190 to 1200 kg (2623.5 to 2645.55 lbs.). The Himiko features ventilated disc brakes at the front and disc brakes at the rear, along with an anti-lock braking system (ABS) for enhanced safety. Steering is rack and pinion with electric power assistance.
