2013 Frankfurt Motor Show: BMW i3, Mercedes GLA And S Coupe The Stars

Man this is big. Too big to see everything. Big enough to have a train-station running through its heart.

Walk every aisle of the Frankfurt Motor Show and you'll walk 46 kilometres; most of the Melbourne or Sydney Motor Show will fit under the domed roof of the Mercedes pavilion alone.

And, at its media opening, the 65th Internationale Automobil-Ausstellung was host to more than 12,000 of the world's motoring press.

That's the Frankfurt Motor Show: a showcase of the best, the newest and the most desirable automobiles on the planet - and of the latest technologies and most extraordinary excess.
