What we do know is that the Kiyora is powered by a surprisingly sensible-sounding four-cylinder direct injection petrol engine and gets Mazda's stop-start system, which means good fuel economy and low CO2 emissions.

At least, it would if it actually existed in the real world. Which it doesn't. Nonetheless, it's another impressively wild looking concept from Mazda. But with chief designer Franz von Holzhausen defecting to Tesla last month, will this be the last of Mazda's super-swoopy concepts?

We hope not... It's even got its own theme tune.
