Our scoopsters have spotted another mystery car undergoing cold weather testing at an undisclosed location in Northern Europe.

To help solve the enigma, our spy photographers told us that at this specific location, they know of two automakers currently testing their vehicles: Citroën and more recently, Qoros Auto, which is a car-start-up created by China's Chery Automobile Co. and investment firm Israel Corp.

While there's a chance the prototype could be a new model for Qoros, we'll agree with our spies that it's very likely a Citroën and more specifically, the next generation of the compact-sized, C4 Picasso MPV.

Lending credence to this is the fact that certain design elements such as the alloy wheels, the door mounted mirrors and even the window line are typical Citroën traits.

Another day, another set of photos of Citroën's new DS concept model. Only this time, French car magazine Automobile managed to snag the DS study without a hint of camouflage, not that it was difficult as Citroën was photographing the new car at the Place de la Concorde, which is one of the best-known public squares in Paris, France.

The French magazine tells us that the concept will most likely carry the DS9 moniker and that it will be revealed in a few days ahead of its world premiere at next month's 2012 Beijing Motor Show.

Now that didn't take long, did it? Less than 24 hours after Citroën shared a pair of teaser photos of a new DS model on its Facebook pages, a blog reader stumbled upon the prototype being hastily covered up on the streets of Paris in France.

The real life shot confirms our suspicions that Citroen's new DS model has a five-door body style, while we'll agree with the folks over at News2zest that its styling looks like a mix of the Metropolis sedan and the GQbyCitroën studies, both of which were shown back in 2010.

The PSA Citroën-Peugeot may be facing some troubles in Europe due to the financial and budgetary crisis, but life goes on and Citroën is looking for ways to increase its sales with the presentation of new models in the mainstream categories.

After the introduction of the new generation of the C4 compact hatchback in 2010, the sub-premium DS4 last year and more recently, the Mitsubishi-based C4 Aircross, the French carmaker is now preparing another proposal for the popular C-segment, the C4 sedan.
