Before the Infiniti QX55, the FX was a Sporty, Unconventional SUV

The Infiniti FX was built for an impressive 15 model years, and yet this sporty SUV is largely forgotten about barely five years after the last one rolled off the assembly line.

The FX — later renamed QX70 — was Infiniti’s original performance SUV. In many ways, it was one of the original performance SUVs, and it assuredly inspired the QX55 that’s just now in showrooms.

Both the original and the redesigned 2009 FX models shared their architecture with the Infiniti G sedan, which just happened to be a close cousin of the Nissan 370Z. These were very good-handling sedans and coupes, and the extra heft piled on by the FX wasn’t a huge detriment.

The original incarnation tipped the scales at a portly 4,200 or so pounds, around 900 more than a G35 sedan. Almost through the end, Infiniti offered both the G’s V6 and a big V8 option, too. Models with the V6 sent their power rearward, with all-wheel drive optional, and mandatory for those with V8s.

Of course, the V8 is the one to have. The original FX45’s 315 horsepower was impressive for 2003, matching the standard output of the Porsche 911. A 6.7-second sprint to 60 mph was very good for the time, especially considering a 2003 FX45 cost a reasonable $45,000.

The FX was also very cool looking. Its humpback shape was unlike any of its contemporaries. Consider that in 2003 the Mercedes-Benz ML55 and the following year’s BMW X5 cast decidedly conventional shadows. FX45s even rode on then (and still) enormous 20-inch alloy wheels.

Orange was the color to have when new, though you’ll have to be the judge as to whether this hue has aged well. Here’s a highly-optioned 2004 FX45 that looks quite clean for less than $7,000 on a used car lot in Cincinnati.

Infiniti lightly tweaked the FX for 2006 and then redesigned it for 2009. The basic shape carried over, albeit with more texture in its detailing. The V6 largely carried over (and eventually grew into the 3.7-liter FX37), but the big news was centered around the FX50. As its name suggests, it came with a new 5.0-liter V8, a now-forgotten downsized relative of the 5.6-liter V8 used in the Armada and Titan, among others. The 5.0 didn’t stick around the Infiniti stable very long, but it lives on in Le Mans Prototype LMP3 racing. Now that’s a fun fact.

Infiniti renamed the lineup QX70 for 2014, though unfortunately there was no 7.0-liter V8 option. In fact, the V8 only lasted a single model year, while the V6 carried into 2017. By then, the QX70 was decidedly long in the tooth and was frequently discounted when new.

Today, however, resale values are surprisingly strong for vehicles that are around a dozen years old in most cases. You’ll want to set an Autotrader alert for a QX70 5.6 since they’re so rare, though the nearly identical FX50 isn’t too tricky to find. Here’s a black one in suburban Indianapolis with 93,000 miles, a reasonable figure for a 2009-model SUV. Find an Infiniti FX for sale
