Both the front and rear light clusters are LEDs and the model is equipped with a 10in infotainment screen and a 7in digital dial display.

The centre module can also move to an angle of 33.5deg, which DS says can “illuminate the sides of the carriageway and follow the driver’s vision in corners” – a feature also available in the Rivoli and Performance Line+. All models are equipped with a digital drivers display as standard.
The new 4 was unveiled along with a bold plan for the French car to straddle two sectors to take on rivals both in the premium hatchback class as well as crossover SUVs. It hopes the 4 will trade on France’s heritage of haute couture as well as the latest technology.
