The QX50 is the SUV-ish thing formerly known as the EX37 before Infiniti decided to make its mysterious naming system 44% more mysterious, starting everything with a ‘Q.’ And before it was the EX37 it was the EX35. The EX35 was introduced way back in 2007 when the first iPhone was the only iPhone and it seemed inevitable that Hillary Clinton would be the Democratic nominee for President of the United States.
The FM bones that underpin the QX also are used as the basis for the Nissan 370Z and Infiniti’s bestselling sedan, the Q50. Every FM-based vehicle benefits from excellent weight distribution thanks to the engine’s placement behind the front axle’s centerline.
The lyrically named VQ37VHR in the QX now displaces 3.7 liters and is rated at 325 hp in spite of lacking any forced induction or leading edge technologies such as direct fuel injection. As in other FM-based machines, the V-6 is mounted longitudinally in the QX50 in the traditional rear wheel drive configuration.
From the B-pillars forward, the QX50’s appearance is only superficially modified. Market conditions in China practically demanded the QX50’s wheelbase stretch. It is there, where being driven while riding in the back seat is very much a thing, that the original 110.2 inch wheelbase was a non-starter.
The QX50 wears its additional length well. In profile it is maybe even better proportioned than before, with the additional inches visually taking some weight out of the middle. Infiniti states the weight for the lightest QX50 at 3855 pounds, and that is a lot for any V-6 to hustle.
It was said that, this version of the Nissan VQ is aided extraordinarily by the transmission’s positive up-shifts and rev-matched downshifts. The new QX50 will get to 60 mph in the middle to high 5 second range, with a quarter-mile time of just over 14 seconds.
The EPA rated mileage numbers sit at 17 mpg in the city and 24 mpg on the highway for both rear and all wheel drive versions. After 25 years, Infiniti still may not know quite what it wants to be. But the QX50, which admittedly sells in really tiny numbers and dates back many years.
