2018 Infiniti Q70 Performance Review

Note: This performance review was created when the 2018 Infiniti Q70 was new.


Performance: 8.2

The 2018 Infiniti Q70 is a pleasure to drive. Regardless of which powertrain you choose, you'll have plenty of muscle to accelerate quickly. This sedan delivers crisp cornering while keeping its occupants comfortable over uneven pavement. The Q70 isn't quite as fuel-efficient as most rivals, however.

  • "This is a genuine sport sedan. The V8 is big and burly, and the steering and brakes are effective. Much is outdated about the Q70, but performance remains a strength." -- Edmunds
  • "Infiniti left the Q70's powertrains alone for 2015 … focusing instead on making improvements to the sedan's throttle response, steering and suspension. But even with those enhancements, the Q70 still needs some polishing." -- Left Lane News (2015)

Acceleration and Power

There are three power plants available for the 2018 Q70, starting with the base 330-horsepower 3.7-liter V6. A 420-horsepower 5.6-liter V8 is optional, as is a hybrid powertrain consisting of a 3.5-liter V6 and an electric motor that together put out 360 horsepower. A seven-speed automatic transmission comes with all three options.

With the V6, the Q70 gets below-average fuel economy ratings of 18 mpg in the city and 25 mpg on the highway. The Q70 Hybrid gets excellent gas mileage for the class, earning 28 mpg in the city and 33 mpg on the highway.

Most drivers will be satisfied with the power from the standard V6 or hybrid powertrain. Acceleration is quick enough to make highway driving stress-free. Still, the optional V8 has noticeably more punch. The automatic transmission is smooth, though it doesn't always downshift as quickly as you might want.

  • "We drove all three models. The V8-powered 2018 Infiniti Q70 5.6 LUXE is the one for power junkies, but we also found the V6 and hybrid models to be more than sufficient in acceleration and passing." -- Autotrader
  • "The transmission serves up precise rev-matched downshifts in manual mode, yet it operates unobtrusively in the daily slog. While passing or merging, however, downshifts can be slow to engage in Drive. Overall, the Q70 is a smooth driver that rarely annoys." -- Edmunds
  • "While fuel efficiency isn't its best attribute, the 5.6-liter V8 in the 2017 Infiniti Q70 has more than enough muscle to help you forget the cost of pure performance. Even the standard 3.7-liter V6 is quite good, offering immediate power for passing and merging. Those looking for diesel-like fuel economy might enjoy the hybrid, which offers better performance than the base V6 and impressive fuel-economy figures." -- Kelley Blue Book (2017)

Handling and Braking

Rear-wheel drive comes standard in the 2018 Q70, and all-wheel drive is available. This sedan manages to have a smooth ride while still handling corners with agility. The Q70's steering is nicely weighted; it is easy to turn at low speeds but doesn't feel too light while doing so. When equipped with the available Sport package, the Q70 handles turns like a pricier European car. Buyers who prefer ride comfort over agile handling will want to skip the Sport package, though, as the firmer suspension and larger wheels can make the sedan feel unsettled over bumpy roads.

  • "The Q70 is a marvelous driving machine, striking the right balance between a comfortable ride and adept handling. The Sport and ProACTIVE packages' taut suspension and active rear steering push the Q70 into BMW territory. The 20-in wheels and tires and the firmer suspension, however, turn the Q70 into a car that enthusiasts will love. Luxury-oriented buyers will likely find it too harsh, though." -- Autotrader
  • "It's responsive and accurate in quick transitions, giving you the sense that the Q70 can be placed precisely around turns. Effort is fingertip-light in parking lots yet firm and steady on freeway slogs. Very good for the segment." -- Edmunds
  • "The Q70's available magnesium paddle shifters allow manual gear change via the 7-speed automatic transmission, and the steering, springs and shocks are all tuned for aggressive driving without returning an overly harsh ride." -- Kelley Blue Book (2017)
