The Honda S660 is a two-seat sports car which fits in the very small Kei car category. It is manufactured by the Japanese manufacturer Honda. The car weighs approx 830kg with manual transmission and 850kg with CVT auto. A prototype was shown at the November 2013 Tokyo Motor Show, the major Japanese auto show event. It is the successor to the Honda Beat. The naming convention of using the letter "S" followed by the engine displacement is a long held Honda tradition going back to Honda's first production car, the Honda S500.

The S660 is a very lightweight, mid-engined, roadster sports car. It shares a platform with the Honda N-One. Its dimensions, because of kei car Japanese legislation, is almost identical to the 1990s Honda Beat, and uses the same three cylinder engine with mechanical improvements.

The Japanese Kei car model is powered by a 660 cc motor with approximately 47 kW (63 hp) and 104 N·m (77 lb·ft) torque to meet Kei regulations. Its introduction signals a return to two-door sports coupes from Honda, taking the smallest position below the larger Honda CR-Z and the top level luxury Honda NSX. It is a modern version of Honda's first mass-produced car, the Honda S500 introduced in 1963.

The mid-engine design balances weight on the front and rear of the car to provide good handling qualities. The design is claimed to have 45/55 front/rear weight balance (exactly even between the axles).

Cars in this size range are not currently regularly sold in the United States. The S660 would be smaller and less powerful than the Mazda Miata, currently one of the lightest production sports cars available in the US.

The development team of the S660 was led by Ryo Mukumoto who beat out 400 other participants in Honda's in-house competition. Honda made him the youngest lead engineer in the company's history even though he had no engineering experience. He was 22 when he was chosen and was given 5 years to develop the sports car.

The prototype and proposed production announcement were widely covered in auto enthusiast news sites and blogs. Initial reactions to the concept were favorable.
