The BMW 640d Gran Coupe has been stacked up against its German diesel competitors, the Mercedes CLS 350 CDI Sport and Porsche Panamera diesel. In this test Auto Express puts the three class leading four door coupes together to see which is the best in diesel form.
As you would expect BMW has a good showing with the all new 6 Series Gran Coupe, owing much of it's success to it's great styling. Unfortunately the pricing on the BMW is not inline with the competitors and that cost it the win.
All three of these cars combine sportiness with striking design and surprisingly affordable running costs. And, if we were judging purely on engineering, design and ability alone, the new BMW Gran Coupe would be a clear winner. Itís handsome, fast and beautifully made, and a delicious combination of form and function. But thereís a problem Ė itís too expensive. Even with similar levels of kit, BMW wants £10,000 more for the car than Mercedes asks for the CLS.
Thanks to its gorgeous styling, intelligent cabin and powerhouse of an engine, the Gran Coupe is a wonderfully competent package. It has the edge on performance, and also feels the most cohesive design here. If BMW could make its price more competitive, this would be the class leader.
Unfortunately for US diesel enthusiasts we won't get this form of the 640d gran coupe. Don't lose hope, BMW recently confirmed that we will be getting a turbo 3.0 liter diesel that could make its way into a state side Gran Coupe offering.
Does a diesel engine in the 6 Series Gran Coupe make sense in the US or not?
