New Merc CLS400d coupe purrs in the Benz
A four-door luxury coupe with one of the finest diesel engines of our time
When I last swung the latest Mercedes-Benz around a few orange cones at its racetrack launch I bemoaned how its curvaceous shape ultimately had no business hunting for apexes on the corners of any racetrack.
That was the CLS 53 AMG — a silky smooth version that belies that it was honed by the company’s AMG engineers. The CLS 400d on test here has expanded the range to two flavours since, and it’s the ultimate testament to that initial protest.
