Based on the firm's standard DS 5LS, the firm's flagship Chinese model revealed late last year, the R version features a more muscular design with new carbonfibre trim.
Finished in special anodised paint, the R model comes with a wide side stripe finished in matt grey, as well as R badging and new 20-inch alloy wheels.
The model also features Citroën's 'DS Wings' grille, finished in dark chrome, as well as a chassis that has been lowered by 15mm over the standard car.
Powering the DS 5LS R is a 1.6-litre turbocharged petrol engine with 300bhp and 221lb ft of torque, connected to a sequential paddle-shift transmission.
Citroën says the car's powertrain is a nod to its World Rally Championship programme. The DS 5LS is the latest car in Citroën's performance car range, following on from the DS3 Cabrio Racing and the DS4 Racing.
