Infiniti Q70 Performance
Automotive journalists write that the 2014 Infiniti Q70 is one of the sharpest-handling cars in its class, though they note that it has a harsher ride than most other luxury large cars. The Q70 should have no trouble keeping up with its rivals, as critics agree that all three available engines provide strong acceleration.
- "Among midsize luxury sedans, the 2014 Infiniti Q70 distinguishes itself with a high level of athleticism, but it comes at the price of a stiff ride quality. If comfort is a priority, rival sedans may prove more satisfying to own." -- Edmunds
- "The 2014 Infiniti Q70 is a blast on the road." -- Kelley Blue Book
- "Regardless of what's under the hood, the Q70 boasts a buttoned-down chassis that's tuned for quick, confident responses and a playful feel on curvy roads." -- Left Lane News
Acceleration and Power
The base 2014 Infiniti Q70 3.7 has a 330-horsepower, 3.7-liter V6. Q70 5.6 trims have a 420-horsepower, 5.6-liter V8. The Q70 Hybrid has a 3.5-liter V6 and an electric motor that make 360 horsepower combined. All Q70 trims come standard with a seven-speed automatic transmission and rear-wheel drive. All-wheel drive is available on the Q70 3.7 and Q70 5.6 trims. According to the EPA, the base Q70 3.7 gets 18/26 mpg city/highway, which is poor for the class. The Q70 Hybrid gets 29/34, which is good for a luxury hybrid and much better than luxury large cars with similar horsepower.
Reviewers agree that the 3.7-liter V6 provides the powerful acceleration buyers look for in a luxury large car, but some reviewers complain that it sounds rough during heavy acceleration. Test drivers agree that the V8 is even more impressive than the 3.7-liter V6 thanks to its potent acceleration, and they say the hybrid model proves that not all hybrid cars are slow. Some critics write that the seven-speed automatic transmission downshifts slowly and has trouble finding the right gear at times.
- "The standard V6 engine pulls strongly, the optional V8 is better, and the hybrid threatens to abolish once and for all the cliche that electrically assisted driving slows things down." -- Kelley Blue Book
- "Any of three engines in the 2014 Infiniti Q70 will deliver the brisk acceleration most shoppers expect in a midsize luxury car. However, more demanding drivers might notice that the 3.7-liter V6 in the Q70 3.7 sounds surprisingly coarse and unrefined during hard acceleration." -- Edmunds
- "The six provides rapid acceleration, while the eight dials up the pace even further." -- Left Lane News
- "The 7-speed transmission can be a real buzzkill at times. In automatic mode, we found it slow to downshift, sometimes seeming as though it were taking its time trying to figure out the best gear for the rpm. We prefer the manual mode for aggressive driving." -- AutoTrader
Handling and Braking
Some critics note that the 2014 Infiniti Q70 has a stiffer ride than many luxury large cars, but they write that it has more athletic handling than many of its competitors. They say it distinguishes itself in sharp turns with a tight suspension and a responsive, nicely weighted steering system. When equipped with the available Sport package, which adds larger wheels and a sport-tuned suspension, reviewers write that the Q70 has even more impressive handling, though they say that ride quality is further diminished.
- "Although the Q70 is not a small car, it does its best to play the role of a sport sedan. It's steady around turns and its steering is responsive, with a heavier effort level than you'd expect on a car in this class. Sport package-equipped cars feel particularly adept on tight, twisty roads. Still, we'd think twice about ordering the Sport package on a Q70 that will be driven every day, because this car rides firmly even with the standard suspension." -- Edmunds
- "There's an impressive array of technology, and as long as you're OK with a stiff ride - a byproduct of the Q70's emphasis on driving performance - you'll have little to complain about." -- Kelley Blue Book
- "The base suspension with 18-inch tires furnishes a taut ride. It's not uncomfortable, but it never seems settled or particularly absorbent. Indeed, we experienced minor crashing and unwanted vertical bounce at higher speeds, disappointing for a midsize premium sedan." -- Consumer Guide (2013)
