TOKYO – Honda will exhibit three new vehicles at next month's Tokyo Motor Show, all powered by 0.66L engines.

The S660 open sports car is billed as a design concept, but it looks to be more than that. Honda won’t comment, but if the model does get the green light for production, sources say launch could come as soon as 2014.

Conjuring up memories of the Honda Beat, an earlier mini sports car, the S660 is powered by a gasoline engine. Honda is releasing no other details for now.

The N WGN and N WGN Custom, also to be featured at the show, will hit dealer showrooms on Nov. 20. Those boxy models will join other N-series vehicles, including the N Box, N Box+ and N-One.

Combined N-series sales between January and September totaled 262,910 units, making it the top-selling vehicle in Japan.
