By now you have probably seen your fair share of spy shots of the third-generation Mercedes CLS, but this time around we have more revealing photos to show you. A camouflaged prototype has been caught on camera at night while getting a refill at a petrol station in northern Europe, thus giving our agile photographers the chance to take a peek inside the lavish cabin.

It’s clearly obvious the dashboard has been lifted straight from the E-Class saloon, but with the elegant design of the air vents borrowed from the coupe and convertible. The test vehicle had an analogue instrument cluster as it’s the case with the cheaper versions of the E-Class. That being said, we won’t be too surprised if the new CLS will come as standard with an all-digital dash taking into account the model is more upmarket and as such it’s positioned between the E-Class and the S-Class flagship.

If you’re not a big fan of the green LED ambient lighting, you’ll be happy to hear the new CLS will be available with a whopping 64 shades, meaning there should be a selectable colour in there for everyone.

Expect all that camo to come off in the following months considering the all-new CLS is rumoured to be revealed before the year’s end. A best-case scenario for the sexy saloon's official reveal would be the Frankfurt Motor Show in September, but it’s too soon to know for sure. The AMG Project One hypercar will be the main star of the event for Mercedes and there's a big risk it would steal the CLS' thunder.

Meanwhile, Mercedes is keeping itself busy these days in Geneva where it’s showcasing the AMG-labelled GT concept, which serves as a preview for a Porsche Panamera fighter set to arrive before the end of the decade. It effectively means the German carmaker doesn’t consider the CLS as an adversary of the model from Stuttgart. Perhaps the CLS is going to become more luxurious while the GT saloon will be sportier given its AMG branding. But where does that leave the CLS 63? All that we know is Mercedes’ lineup expansion is far from being over.
