America is missing out on this cool Japanese sports car.
The mini Honda S660 Japanese roadster has never been sold in the US, and that's a crying shame. Measuring just 133 inches long, it's even smaller than the Mazda MX-5 Miata, but kei cars are designed exclusively for the Japanese market. Just to make us jealous, aftermarket tuner Mugen is now offering some new components previewed by the Mugen S660 Concept at the Tokyo Auto Salon earlier this year that spices up the compact Japanese sports car.
At the front, the tuner has added a new splitter that makes the front fascia look more aggressive without sacrificing the styling - it's certainly more subtle than Liberty Walk's take on the Honda S660.
In addition, optional LED fog lights and aero illumination can be added. The standard front and rear bumper can be replaced with more aerodynamic bumpers featuring a two-tone finish, and a new diffuser dominates the rear. New side sills and forged 15-inch aluminum wheels also give the Honda S660 a sportier look.
To improve the handling, Mugen has added chassis dampers that "eliminates unpleasant vibrations and noises, and improves steering stability." For the 2020 model year, the Honda S660 was updated with some minor styling tweaks, new exterior paint options, and body-color A-pillars.
The interior was also upgraded with heated seats and a steering wheel and gearshift wrapped in Alcantara. Mugen hasn't made any modifications to the turbocharged three-cylinder engine, but since this is a kei car regulations require the engine size to be limited to 660 cc and the power output to be capped at 63 horsepower, which is sent through either a six-speed manual or a CVT.
That may sound like a modest amount of power, but the Honda S660 weighs less than 2,000 pounds. We imagine this setup makes the S660 great fun to hoon around, but we'll never know since it will never be sold in America.
