With Auto China 2014 opening its doors this week in Beijing, we take a look at a few of the show cars with star potential. Citroen will reveal its DS 5LS R Concept -- a luxury saloon fitted with lightweight carbon fibre components to maximise the performance from its 300bhp, 1.6-litre turbo petrol engine. Bentley will pull the covers off the Mulsanne-based Hybrid Concept. The luxury car maker's first ever hybrid uses copper as a styling element to highlight its electrical veins, which endow it with an emissions-free, electric-only driving range of up to 50km. Finally, Infiniti will premiere a short film of the Q50 Eau Rouge development prototype being put through its paces by Director of Performance and Formula 1 World Champion, Sebastian Vettel.
