I drove the new BMW X5 the other day, and there was nothing about it to surprise. It looked much the same. It drove much the same. It provided the same cabin ambience and even smelt much the same. But, we shouldn’t be surprised at this lack of novelty, because the X5 is a big success.

BMW has sold 1.3 million of the first two iterations of this car, which debuted in 1999. It’s a car that earns BMW good margins according to board member Herbert Diess and also launched the entire X-model sub-brand for BMW.

So this is a car that it cannot afford to get wrong and like VW and its Golf, a car now best-known for staying the same, BMW has found a formula with the X5 that it’s probably best not to meddle with. Striking automotive gold like this is hard, which is why the planet’s smash-hit cars tend only to progressively evolve, and without deviating from their essence.
