2015 Infiniti Q50 Performance Review

Note: This performance review was created when the 2015 Infiniti Q50 was new.


Performance: 7.8

Test drivers agree that the 2015 Infiniti Q50 has potent acceleration, and many think that it offers a fun overall driving experience. However, they recommend avoiding the optional adaptive steering system because it isn’t very communicative.

  • "Out on the road, there's little need for any extra power, and the Q50's suspension is equally good at tackling day-to-day commutes as it is at bringing a more aggressive mountain road to its knees." -- Kelley Blue Book
  • "As for the rest of the 2014 Infiniti Q50, it's what we've come to expect from the Infiniti G37: a quite good sport sedan with a well-balanced, rear-wheel-drive chassis; a very strong, 328-hp V-6 that's well mated to a seven-speed automatic; and an attractive exterior and interior." -- Automobile Magazine (2014)
  • "Its newfound interior refinement doesn't get in the way of an enjoyable driving experience. It still offers plenty of power, very good balance, faith-affirming brakes and - praise be - standard hydraulic steering with actual road feel." -- Autoblog (2014)

Acceleration and Power 

The 2015 Infiniti Q50 comes with a 328-horsepower, 3.7-liter V6 engine and a seven-speed automatic transmission. The 2015 Q50 gets an EPA-estimated 20/29 mpg city/highway, which is decent for a V6-powered upscale sedan, though six-cylinder competitors like the BMW 335i and the Acura TLX get better fuel economy.

The Q50’s engine delivers remarkable acceleration, according to automotive journalists, though some note that it sounds a bit rough at higher RPMs. Most critics also write that the transmission provides smooth gear changes.

  • "The standard 3.7-liter V6 delivers smooth and decisive acceleration, making it a standout in its class." -- Edmunds
  • "We love how the V6 under the Infiniti Q50's hood pours out plenty of power and torque, even if it does get a bit raspy at higher revs." -- Kelley Blue Book
  • "The internal combustion 328-hp 7-speed lineup produces brisk acceleration and smooth shifts. …" -- AutoTrader (2014)

Handling and Braking

The 2015 Infiniti Q50 comes standard with rear-wheel drive or optional all-wheel drive. Q50S models come with larger wheels, a sport-tuned suspension and larger brakes. The Q50 is available with a Direct Adaptive Steering (DAS) system, which allows drivers to adjust the Q50’s steering effort and turning radius. However, test drivers say the DAS system doesn’t feel as responsive as the standard steering, so they recommend avoiding it. Most critics say that the Q50 offers very agile handling overall, and auto writers also praise the Q50’s strong brakes and smooth ride.

  • "In terms of handling and steering, the Q50S receives high marks for its quick responses, composed ride and predictable nature." -- Edmunds
  • "The system is able to react more quickly than is possible with a normal mechanical system, and it also allows the driver to tailor steering effort and speed to suit his or her tastes. However's its worth nothing that the setup has drawn criticism for artificial-seeming feedback and an anodyne overall feel." -- Left Lane News (DAS)
  • "The Q50 drives with a secure, surefooted and swift grasp of the road. But real driving enthusiasts will want to skip the electronic steering and stick with the standard hydraulic system." -- AutoTrader (2014)
  • "The ride is simply more composed than what BMWs have taught us to expect with this sort of rubber, even if ultimate grip isn't all that it should be (a proper set of conventional summer tires would help)." -- Autoblog (2014)
