It’s a good job the Frankfurt motor show only comes around every other year; so large and all-encompassing is Europe’s biggest car expo that if it was any more frequent, the global motoring industry might struggle to make enough new metal to fill it.Don’t believe us? Then take a look at the sheer quantity of new cars that will star inside the two million square feet of Frankfurt’s Messe next week. Our list (below) runs to 52 new concept and production cars, ranging from the VW City Expert concept (the alleged 21st century successor to the VW Beetle) to the new, million Euro Lamborghini ‘mega-Murcielago’. Many of them are collected in our gallery. And those are just the ones we know about right now; factor in the show’s surprises (of which there are sure to be many) and the list will expand to epic proportions.Most of the cars featured in the list below are what’s known in the industry as “global premieres”; that means they haven’t appeared anywhere before, ever. A few have been shown once or twice in other far flung locations, but all of them are worthy of closer inspection by anyone interested in new cars. To read more about any one of them, click on its name below.The 62nd International Motor Show at Frankfurt opens its door to the public between 15 and 23 September, at Frankfurt’s city centre Messe. Entrance costs EUR 13 per person during the week, and EUR 15 at weekends. For more information, visit www.iaa.de.
