Dubbed 'DSX', the new model will reportedly debut first as a concept, based on the DS5 wagon that launched in Australia last year.
According to France's Auto Plus, the DSX will make its production debut first in China from early 2014, hitting Europe and global markets later in the year.
An overall length of around 4.7 metres is expected - around the length of the Audi A5 - and powertrains should include both petrol and diesel options.
As an SUV, an all-wheel-drive variant is expected, but with power supplied by Peugeot Citroen's Hybrid4 147kW diesel-electric system.
The company's familiar 1.6 litre turbocharged petrol engine will reportedly also feature, offering around 180kW in DSX form.
Watch for more details to come in the lead-up to the Shanghai Auto Show.
