Honda S660 Concept revealed – the Honda Beat returns

The Honda S660 Concept (pictured) will debut at the 2013 Tokyo Motor Show It looks like Honda is making a return to the Kei car with the arrival of the Honda S660 Concept ahead of the Tokyo Motor Show next month. The Kei class of car in Japan is small (less than 3.4 metres long) and comes with a raft of tax breaks for buyers, but despite it being designed just for Japan it’s gained a cult following round the world, and now the Honda Beat for the 21st century has arrived in the form of the S660 concept. The S660 Concept – it gets the required maximum 660cc Kei engine limit – is a mid-engined open top roadster that manages to deliver 64bhp from its 3-cylinder engine which, with a weight under 900kg, should be reasonably lively.

Preserving this year's hits as the museum pieces of the future is one of the great backroom issues of the auto industry. If you need to see the first wood-paneled Honda Civic Country station wagon from 1980 for some good reason, Honda has one in storage in Japan.
