Infiniti QX70 Performance
Reviewers like that the 2014 Infiniti QX70 offers powerful engine choices, though a few note that the base V6 could operate a bit more smoothly under hard acceleration. Still, critics note that the QX70 feels nimble and planted through turns, delivering a sport sedan-like driving experience.
- "Sometimes, you can judge a book by its cover - the QX70's aggressive stance and muscular lines suggest that this crossover is all about performance, and it certainly has all the right stuff under the sheetmetal to back up that impression." -- Left Lane News
- "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." -- Car and Driver (2013)
- "Built using the same architecture as the Infiniti G37 sport sedan, the FX offers a level of carlike performance rivaled by few crossovers or SUVs." -- Edmunds (2013)
Acceleration and Power
The 2014 Infiniti QX70 comes standard with a 3.7-liter V6 that produces 325 horsepower and a seven-speed automatic transmission. A 5.0-liter V8 that produces 390 horsepower is optional. The QX70 gets up to an EPA-estimated 17/24 mpg city/highway, which is on par with the fuel economy of other SUVs in the class.
Reviewers are pleased with the abundant power from the standard V6, though most think that the V8 makes the QX70 feel much faster. Test drivers report that the QX70’s transmission shifts smoothly and quickly when more power is needed.
- "The QX70 3.7 is powered by a 3.7-liter V6 engine that generates 325 horsepower and 267 lb-ft of torque. Power is abundant with this engine, although acceleration can feel slightly taxed when you add the weight of the all-wheel-drive system. The QX70 5.0 gets a 5.0-liter V8 good for 390 hp and 369 lb-ft of torque. For pure performance and unhindered acceleration, this is the engine to have." -- AutoTrader
- "With 325 horsepower, the V6-powered QX70 is plenty capable in rear- or all-wheel-drive form, while the 390-horsepower V8 version that comes standard with all-wheel is seriously quick on its feet. The 7-speed automatic transmission is ready to downshift at a moment's notice and has an effective manual-shift mode that includes a satisfying throttle blip on downshifts." -- Kelley Blue Book
- "The V6-powered FX37 delivers a smooth stream of power while the seven-speed automatic transmission executes shifts quickly and smoothly. Manually shifting provides slick, matched-rev downshifts. Most drivers will find that this engine provides more than enough power. For those who still need more, the FX50 obliges with a flood of torque that launches this midsize crossover toward the horizon with ease." -- Edmunds (2013)
- "The seven-speed automatic also delivers quick downshifts when necessary and remains unobtrusive in normal driving, serving up smooth transitions between its numerous gears." -- Autoblog (2013)
Handling and Braking
The V6-powered QX70 has standard rear-wheel drive or optional all-wheel drive, while the V8-powered model comes standard with all-wheel drive. Reviewers say that the QX70 is nimble through turns and feels well-balanced and planted to the road. Some critics also write that the QX70 has a comfortable ride, but others think it’s a bit too firm to be comfortable. Test drivers report that the brakes are strong and they like the QX70’s, quick, direct steering.
- "If you're lucky enough to test drive the 2014 Infiniti QX70 on a winding mountain road, you'll learn all you need to know about why this is the driving enthusiast's luxury SUV. The QX70's well-balanced chassis, tight turning radius and wide stance allow it to round curves that would have other SUVs teetering on their sidewalls." -- AutoTrader
- "The Infiniti QX70's nicely balanced weight distribution, all-independent suspension and powerful V6 or V8 engines makes for a fine-handling SUV. Balance also comes into play with the QX70's ride, which captures the oft-elusive combination of being comfortable yet sporty. Throw the Infiniti into a corner, and you might be surprised at just how agile it feels for its size." -- Kelley Blue Book
- "Underpinned by a version of the RWD-based architecture used by the 370Z, the QX70 offers crisp responses to control inputs along with a taut - but not uncomfortable - ride." -- Left Lane News
- "With a fairly quick steering rack and capable brakes, the FX37 will paint a smile on your face if you let it, and while the tall ride height can't help but serve up a bit of body roll, the engineers at Infiniti have done an impressive job of keeping every one of the five-door's 4,209 pounds in check." -- Autoblog (2013)
