The 635d has a straight-six twin-turbo 3.0-litre turbodiesel that’s hard to fault. It offers even more torque than the V10 M6, and there’s no arguing with 0-60mph in a mighty 5.7 seconds.

On the road, it feels extremely fast, especially in kickdown. However, it’s the effortless nature with which it gains speed that really impresses, while the engine remains unruffled even when pushed hard. Through corners, the BMW continues to impress. There’s lots of grip, the steering has good feedback and it remains composed. However, this involvement does lead to a firm ride and a surprising amount of road noise. It’s not comfortable enough to be a true GT.
