2019 Infiniti Q70 Performance Review

Scorecard

Performance: 8.3

The 2019 Infiniti Q70 gives you a choice between two powertrains, both of which deliver ample power and acceleration for most driving situations (with the V8 really standing out). Gas mileage is low for the class. The Q70 generally handles well, but its ride quality gets mixed reviews.

  • "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 Much is outdated about the Q70, but performance remains a strength."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 (2018)
  • "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

The Q70's base engine is a 3.7-liter V6 that puts out 330 horsepower. It's mated to a seven-speed automatic transmission. This engine delivers plenty of power for driving around town and on the highway, and it provides quick acceleration. The transmission, however, sometimes hesitates to downshift when passing or merging.

The 5.6-liter V8 produces 420 horsepower and makes its presence felt every time you hit the gas. It makes the Q70 feel almost like a sports sedan.

With the V6, the Q70 gets an EPA-estimated 18 mpg in the city and 25 mpg on the highway, which are some of the worst ratings in the class. Ratings dip to 16/24 mpg city/highway with the V8.

  • While newer luxury sedans are migrating to small-displacement, turbocharged engines, the 2019 Infiniti Q70 soldiers on with a normally aspirated V6 or V8. Both engines deliver excellent power and loads of low-end torque, but also contribute to rather dismal fuel-economy figures. Most customers will find the 3.7-liter V6 more than adequate. … Moving to the 5.6-liter V8 increases output to 420 horsepower and turns the Q70 into a sleeper sedan capable of delivering startling quick response when the throttle's kicked wide open." -- Kelley Blue Book
  • "The big V8 accelerates effortlessly at full throttle, although low-rpm power is soft compared to what rival turbocharged engines produce. In our testing, the 0-60 mph sprint took 5.2 seconds - unremarkable for 420 hp – but there's plenty of real-world punch. This is a fast car." -- Edmunds
  • "The V8-powered 2018 Infiniti Q70 5.6 LUXE is the one for power junkies, but we also found the V6 … to be more than sufficient in acceleration and passing." -- Autotrader (2018)

Handling and Braking

The Q70 isn't a sports car, but several reviewers note that it handles well for a midsize sedan. The steering is sharp, and the car handles turns without complaint. Still, some think the ride is on the firm side, while others counter that the Q70 feels more oriented toward comfort than anything else. Rear-wheel drive comes standard, and all-wheel drive is available.

  • We found the Q70's ride more comfort-oriented than performance, which again may hold appeal to a large segment tired of overly stiff-riding luxury cars." -- Kelley Blue Book
  • "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 (2018)
  • "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 (2018)
