Honda unveiled the S660 concept at the 2013 Tokyo Motor Show. The mid-ship mini-sports concept bears a strong similarity to the EV-STER concept presented during the 2011 Tokyo Motor Show as a mini electric vehicle. The concept has been scheduled for production in 2015.

"The model embodies the freewheeling thinking of young Honda engineers, who want to make a cool car that is unique to Honda. I would like our customers around the world to feel the strong spirit of Honda," according to Takanobu Ito, CEO of Honda.

Honda has decided to ditch the electric engine for the S660 in favor of a 65 PS mid-mounted 660cc 3-cylinder turbo engine with a seven-speed CVT. The production version is said to have a retractable roof and will initially be sold in Japan.

Honda brought the EV-STER to the LA Auto Show last year and to Chicago earlier this year, which indicates it might be sold outside Japan. With announcement of a 1.0-liter VTEC Turbo engine, it might be possible that the International version of the S660 could be powered by a the 1.0-liter engine and called an S1000 instead.
