The Mercedes CLS is about to get a mid-life refresh, and our spies have spotted a prototype wearing minimal disguise out winter testing in Germany. We expect to see the redesigned CLS arrive in showrooms by the end of the year - and these pictures show only minor styling tweaks for the updated model.
Most noticeable are modified front and rear bumpers, while the flanks of the CLS appear to feature crisper lines. Round the back there is a new taillight design.
While we don’t have images of the interior we know Mercedes will fit a larger COMAND display screen, mounted within the dashboard. Changes will also continue with a new steering wheel and larger control unit fitted to the center console.
In terms of engines, we expect the current lineup to be carried over, which includes a range of petrol and diesel six-cylinder powertrains, plus a four-cylinder 2.1-litre diesel capable of returning 54.3mpg. The range-topping CLS 63 AMG will adopt the same 557bhp 5.5-litre twin-turbo V8 as the current model, with an AMG S variant is expected using a tuned version of the same engine, rated at 585bhp.
