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.
Inside, the new concept features a leather and Alcantara-trimmed cabin with new upholstery and embossed DS logos. New carbonfibre inserts also feature on the steering wheel, as well as the door handles and panels.
Like the standard DS 5LS, the R is only likely to be sold in the Chinese market if it makes production. The DS brand exists as a seperate entity from Citroën in the country, with a total of five models sold through a network of 50 'DS Stores'.
