Mercedes-Benz is in the midst of preparing the next-generation CLS, which has been sighted by our spy photographers again. This time, the test mule seen here is wearing a lot less camouflage compared to a previous protoype, and we also get a good look at its interior.

The new CLS will reportedly be based on the W213 E-Class platform, although it will be slightly larger in size to fit into its position between the E-Class and S-Class. Based on the photos here, the CLS will come with a much wider front grille and lower intake compared to the E-Class. As a result, the car also gets its own headlight design that appears almost trapezoidal in shape.

Viewed from the side, the CLS’ coupe-esque profile becomes apparent, with what appears to be a lower roofline that slopes more gently downwards towards the rear. There, you’ll find taillights that mimic those found on the new C238 E-Class Coupe, with a pair of exhaust tailpipes in the lower apron.

The interior meanwhile, appears to be largely adopted from the C238 given the design of the centre air-conditioning vents as well as the general layout of the dashboard and centre console. The former features an analogue instrument cluster with a coloured display, although we should expect Mercedes’ Widescreen Cockpit with twin 12.3-inch displays to be an option.

The familiar COMAND Touchpad Controller on the centre console provides access to the car’s infotainment system, and it shares the area with the car’s climate control, quick access buttons, and an analogue clock.

Another thing to note is the ambient lighting, which now appears to cover an additional part of the interior – the air-conditioning vents. On the C238, the lighting feature can be seen on the sides of the centre console, the dashboard, and near the door-mounted seat controls. Here, the lights are set to show a green hue, although Mercedes will likely offer a wider colour palette.

Expect the CLS’ engine line-up to follow the E-Class, with a range of turbocharged four-cylinder, V6, and V8 mills on offer. The latter will likely be reserved for a range-topping AMG version, which should come with a nine-speed automatic gearbox and 4Matic all-wheel drive, similar to the new Mercedes-AMG E 63.
