The report on Japanese website Response doesn't confirm the production car's specifications, but it's widely expected to carry over many of styling elements first seen in the S660 concept car (pictured) that debuted at the 2013 Tokyo motor show.
To fall within Japan's kei car category, which offers generous tax breaks, the S660 concept is powered by a 660cc turbocharged three-cylinder engine with 47kW of power and 104Nm of torque. Being a kei car the S660 can't exceed 3400mm in length and 1480mm in width.
It's not yet clear whether the S660 will be sold outside of Japan, but if it does make it beyond the mother country the car is expected to be fitted with larger and more powerful 1.0-litre turbo engine. Regardless, 2015 looks set to be a big year for Honda as it injects a bit more verve into its portfolio. Other sports cars it has lined up for next year include the turbocharged Civic Type R, which we've driven in prototype form, and the long awaited follow up to the NSX that will feature a hybrid drivetrain and be produced in the USA.
Response claims that Honda finalised its decision to produce the S660 on April 15, 2014 and that it will contract out production of the car to Yachiyo Industry's Yokkaichi factory. This plant currently handles some production of a few kei cars in Honda's range and was the home to the S660's spiritual predecessor, the 1990s Honda Beat.
