We’ve been drooling over the Honda S660 ever since the mid-engined kei car launched in Japan in 2015. Unfortunately, rumors of Honda taking the diminutive sports car global have been greatly exaggerated, leaving us no option but to merely report on the various variants, special editions and custom body kits the automaker has launched over the past five years. Mind you, the latest S660 project is not an official Honda effort, but that doesn’t make it less interesting. On the other hand, you could say it’s semi-official, given the very close ties between Honda and Mugen Power.

On August 28, the tuner will be releasing styling and suspension upgrades for the facelifted 2020 S660. On sale at Honda Cars and Mugen Parts dealers across Japan, the parts are inspired by the Mugen S660 Concept unveiled at the 2020 Tokyo Auto Salon. For the exterior, the custom parts include a front aero bumper, side skirts, and rear aero bumper, all made of vacuum-formed PPE. Replacing the standard item, the front bumper features a two-tone finish combining the vehicle’s body color with a Dark Gun metallic paint, while it can be had with optional LED fog lights and aero illumination.


At the back, the aero bumper is compatible with both the Mugen sports silencer and the standard muffler. It comes exclusively in the vehicle body color and replaces the standard one. Tying the two custom bumpers together are the large side skirts Mugen Power spoilers. The skirts are attached to the bottom of the body sides and come in a two-tone finish combining the body color with Dark Gun metallic paint. Rounding out the exterior upgrades are the newly designed ‘FR8’ forged aluminum wheels in a Graphite Gun metallic finish. Interestingly, they come in a staggered setup with 15×5-inch rims on the front axle and 16×6-inch ones at the back, with 165/55 R15 and 195/45 R16 tires respectively.

When it comes to improving the S660’s driving characteristics, Mugen offers a set of Yamaha Performance Dampers, which vibrations and noises over rough surfaces and improve steering stability, maneuverability, and handling. Bundled up, all these custom parts will set customers back 583,000 yen (US$ 5,000). By the end of this year, Mugen Power says it will launch more custom parts for the Honda S660, including carbon front grilles, rear wings, engine hoods, sports silencers, and bucket seats.
