2013 Infiniti FX37 AWD Review

Posted on Infiniti

Infiniti’s sporty FX crossover has had a busy two years, receiving a face lift for 2012 before swapping its base 3.5-liter V-6 engine for a 3.7-liter for 2013. Besides adding more power, the new V-6 brings a displacement-driven name swap from FX35 to FX37. Even more flux is on the horizon, thanks to Infiniti’s recently announced lineup-wide naming overhaul. Next year, the FX37 becomes the QX70; confusingly, the same badge will be applied to the V-8–powered FX50, and the moniker change isn’t expected to coincide with a redesign or update. To people reading this review of the FX37 in 2014, simply replace any mention of FX37 with QX70.

VQ Doesn’t Stand for “Very Quiet”

As does the 3.5-liter it replaces, the FX37’s 3.7-liter V-6 belongs to Nissan’s VQ engine family. Variations of the same engine have long powered Nissan’s 370Z and Infiniti’s G37 and M37, and it is being added to the smaller EX crossover’s engine roster this year, too. The good news is the powerplant’s power. In the FX37, it makes 325 horsepower and 267 lb-ft of torque without turbos. The bad news is it’s coarse and unrefined. Push hard, and a faint vibration occurs in the shifter, steering wheel, and pedals. The engine’s unique baritone wail mostly sounds good, but it’s better from outside the car. Inside, it can sound slightly thrashy.

Unfortunately, to really hustle the FX37, you’ll be spending plenty of time at or near the six-cylinder’s 7500-rpm redline, where the sound is especially unpleasant. The 3.7-liter doesn’t make its maximum 325 horsepower until 7000 rpm, and all 267 lb-ft of torque aren’t available until an also-lofty 5200 rpm. All things being nearly equal—our FX37 was a negligible 67 pounds heavier than the last FX35 we tested, a 2009 all-wheel-drive model, and the engine spins through the same seven-speed automatic transmission—you’d expect the FX37 to outperform the FX35. Instead, it ties the old model. Complete review on www.caranddriver.com, by ALEXANDER STOKLOSA
