You would have thought that Toyota, probably the word’s biggest carmaker with sales of 9.9m units in 2012, would be pretty happy with the way things are panning out.

True, the company slumped into a £2.6bn loss after the 2008 financial crisis. And, like all the Japanese carmakers, it suffered badly with the double - and closely spaced - disasters of the Thai floods (where many suppliers are based) and then the massive earthquake and Tsunami in 2011.

And Toyota isn’t well placed in the global premium car market (Lexus is a relative minnow), but then again in the year 2012-13, it banked a profit of £6bn.

But Toyota’s not happy. Indeed, on the opening morning of the Tokyo motor show Mitsuhisa Kato, the company’s Executive Vice President for Research and Development, made an emotional presentation on the Toyota stage.

Kato related the story of Toyota chairman Aiko Toyoda who was one of the drivers when Toyota entered the Nurburgring 24-hour endurance race with a LFA supercar. One of teams with three professional racing drivers, the Lexus LFA came 37th overall out of 175 entrants.

Kato said that once Toyoda had returned to the pits he became ‘quite tearful’. This, he said, was because the Toyota pit crew covered everybody from ‘the newest recruits to the chairman’.  Kato (who oversaw the development of four generations of the Corolla) made a plea to the audience that cars must never become ‘just transport or just a tool. We must never make cars that are neither love nor hate cars’.
