Citroen DS 5LS R revealed as high-performance DS5 for China. Debuts at Beijing.

The Citroen DS 5LS R (pictured) heading for a Beijing debut The Citroen DS 5LS was revealed at the end of last year as Citroen’s biggest DS model to date, but as it’s aimed at China there’s little chance we’ll see it in the UK or Europe, where there’s no real market for a stretched DS5. And the same goes for the ‘Racing’ version revealed this morning – the Citroen DS 5LS R – which is heading for a debut at the Beijing Motor Show later this month. Under the bonnet of the DS 5LS R sits the 1.6 litre petrol turbo found in the Peugeot RCZ, where it gets 270bhp, but Citreon have managed to boost that to 300bhp – which should make putting the power down quite interesting.
