"The crossover formerly known as the Infiniti EX, and presently known as the Infiniti QX50, isn’t exactly a crossover at all. It’s not tall, blocky or towering. A person of average height can see the top of its roof. Entry occurs after stepping in over a thin sill, followed by a plunk down, as if boarding a sedan. Seated, you’re not left towering over the road, or surrounded by excessive space."
There is a reason for that. It's essentially a 5 door version of the previous G37 sedan. In Japan, Nissan marketed the G37 as the Nissan Skyline and they offered a sedan, coupe and this 5 door version.
