What's all this about?

The famous BMW Art Cars - motorsport machines daubed by some of the world's leading artists - are currently on a world tour, to celebrate 40 years since the first one came into being.

Which ones are on display?

Just five of the 17 rendered are part of the 40th Exhibition, which has already been to Hong Kong, Paris and Munich, and which is now at the Concours d'Elegance in Italy. This display will head on to New York, Miami and Shanghai later this year.

Go on, tell me the five, then.

The original four plus the latest car are the chosen few, but these are some of the most iconic 'rolling sculptures' yet created. Two 3.0 CSLs - the 1975 Alexander Calder original and the 1976 Frank Stella follow-up - are joined by Roy Lichtenstein's 1977 Group 5 320, Andy Warhol's 1979 Group 4 M1 and the Jeff Koons M3 GT2 of 2010.
