The Mercedes-Benz press conference at the Frankfurt motor show wasn’t one to miss. Never is. Germany’s blue-chip car-maker has the venue’s ‘Festhalle’ all to itself – a multi-storey space right at the heart of the Messe – and within it must have been crammed at least a quarter of all the 10,000 registered media that are here.

The floor show was absolutely first rate: so good you wondered if you were watching a car unveiling or a variety performance. Dancers, singers and trapeze artists followed a live band, and there was just enough time in between the cabaret acts for Daimler boss Dieter Zetsche to unveil the new GLA compact crossover, and three additions to the S-class range: the 94mpg S500 Plug-in Hybrid, the 577bhp S63 AMG and the S500 Intelligent Drive. The latter’s the modified S-class that, using mostly series-production technology, demonstrates Mercedes’ intent to put a self-driving car into the showroom before the end of the decade.
