In Europe at least, the 5 Series GT represented a rare misstep for BMW.

Conceived as a fallback in case legislation, economic downturn or snowballing buyer-consciousness killed off the large SUV, the 5 GT has spent a lifecycle looking like the answer to a question that no one had asked.

Beyond its frumpy appearance (see pic below), part of the problem was its placement: who needed a car that was practically the length of a 7 Series with vast rear headroom but not a vast boot? The decision, then, to move the concept upmarket is understandable. In the headier atmosphere of the 6 Series’s reputation, the product might find customers more inclined to embrace the idea of an expensive liftback that’s neither a pure-blood tourer nor a full-blown X-car.
