The Vauxhall and Opel badged Insignia has been on the market since late 2008 and last year it received a mid-life facelift.
The model clearly needs a bigger update soon and what we have here is very likely the first mule for the next-generation model expected for 2016.
It looks like they are testing something new underneath the bonnet. Of course it could be just a new engine they are testing, but very unlikely as the updated model was launched last year and next-generation model is very needed to stay competitive.
The new design is purely speculative, but we have a feeling it will be more of an evolution, rather than something totally new compared to the current model.
Of course there will be some major changes under the bonnet, along with new tech and safety features.
We expect to see first full-body prototypes in late 2014 or in early 2015.
