Some cars have straightforward advantages: pickups give you towing capacity, hatchbacks are practical, and sports cars give performance. Then there are cars like the 2018 BMW X6. Is it a crossover? Not quite, it’s a little too big. Is it an SUV? Technically, yes, but the roofline will have you thinking otherwise. Is it a sports car? It’s certainly fast, but it’s not one of those either. It’s hard to categorize, and it’s a polarizing design. The X6 has some winning features, and in today’s world of all-in-one promises, why not have an SUV that looks like a coupe? All the same, the elements of the X6 are disparate enough that they bring substantial compromises. The right buyer might love it, but for more straightforward value…well, we’d look somewhere else.
