Top 5 most important cars at the 2013 Frankfurt motor show

The five most important memorable cars in attendance at the world’s biggest motor show Nothing is as controversial as irritating your core enthusiasts, and the Audi Sport Quattro concept risks doing just that. Its name and styling riff off one of the most iconic cars in Audi’s back catalogue – and in WRC history – yet the new yellow version unveiled at the 2013 Frankfurt motor show has abandoned the five-cylinder engine, manual gearbox, and respectable kerbweight of the 2010 Quattro concept. In its place, we’ve an RS7-based coupe with the power of a Lamborghini Aventador (691bhp), twice the claimed economy of a Golf GTD (113mpg), but only because of a twin-turbo V8 mated to a hefty hybrid powertrain, and that means this new Sport Quattro weighs as much as a Bugatti Veyron Super Sport (1845kg).

Citroen DS3 at Frankfurt

  Citroen will be bringing the new DS3 to Frankfurt The DS3 – a MINI competitor – is the first model in Citroen’s DS range, designed to be an upmarket range of cars based on their more prosaic ‘C’ siblings. We can expect to see the Citroen DS4 in 2011 and the bigger Citroen DS5 in 2012. The DS3 is based on the new Citroen C3 – which will itself only be launched in November – and is slightly larger all round than the MINI.

BMW Zagato Roadster

BMW and Zagato turned heads at the 2012 Pebble Beach Concours d'Elegance with its latest collaboration: The BMW Zagato roadster, just months after the unveil of the unveil of their coupé at Villa d'Este. The car, developed in just six months, features a low-set kidney grille – complete with tiny matt-sheen Zagato 'Z' letters – and circular headlamps on a sharply lined contoured hood, while Zagato's signature double-bubble design is seen again on the car and serves to extend the lines of the hood to the rear. Like the coupé version it is again the work of Norihiko Harada, Zagato's Chief Designer.
