The miniaturisation of the American car was the theme that dominated proceedings at the LA motor show yesterday. Four years is the blink of an eye for the motor industry in general, and yet four years ago, I went to my first American motor show in Detroit and found it awash with hulking pick-ups, SUVs, MPVs - exactly what I expected.

Since then, America's seen unprecedented fuel prices, and its car business has come under pressure from competitors and legislators to work towards greater fuel efficiency.

Which is why, yesterday, production cars like the Mazda 2, Ford Fiesta, Chevrolet Cruze and Scion xD took centre stage, and concepts such as the VW Up Lite, Honda P-Nut, Lexus LF-ch and Lincoln C shared the limelight with them. There was hardly one D- or E-segment debutant to speak of.

The really heartening thing was seeing the locals warming to these small cars. Four years ago, I'm sure they would have turned their noses up at a lot of them; dismissed them as poor value for money, or somehow second rate.

Yesterday, though, their enthusiasm for the compact car was very real and very evident indeed. When ford unveiled the Fiesta there were ever coos of appreciation.

Viva la revolution.
