2018 Infiniti Q70 Review

Despite its good acceleration, balanced handling, and strong predicted reliability rating, the 2018 Infiniti Q70 sits at the bottom of our rankings. This is partly because its interior design and technology feel outdated compared to rivals.

  • Good gas mileage with hybrid model
  • Roomy interior

Is the Infiniti Q70 a Good Car?

The Infiniti Q70 isn't a horrible car, despite its low ranking. Its deft handling and powerful engines will please driving enthusiasts, and its cabin is roomy enough to keep all occupants comfortable. The Q70 also has one of the higher predicted reliability ratings in the class. Still, its interior doesn’t match up well with that of most competitors, and while its performance is pretty good, it doesn't measure up to some of the best performers in the class.

Should I Buy the Infiniti Q70?

Many luxury midsize cars offer even better performance and much nicer interiors than the Q70, for significantly less money. You can also find more premium and high-tech features in most rivals. For these reasons, we don't recommend buying the 2018 Q70.

Should I Buy a New or Used Infiniti Q70?

For 2018, Infiniti changed the Q70's trim names (adding "Luxe" to the designation) and made some other minor changes. If you're open to driving a used car, you may want to consider purchasing a used Q70 to potentially save thousands of dollars. The 2016 and 2017 models are nearly identical to each other, and you can get all of the same features that a new Q70 offers. It's just a matter of hunting around to find what you want.

Infiniti Q70 Versus the Competition

Which Is Better: Infiniti Q70 or Audi A6?

The Audi A6 beats out nearly all other luxury midsize cars, including the Q70. It has high-end performance with thrilling handling, several powerful engine options, and better gas mileage than the Q70. Inside, the elegant A6 has modern, upscale styling that outshines the Q70's dated interior. It's hard to top the A6 for technology; it has a user-friendly infotainment system and futuristic features, like handwriting recognition and advanced smartphone integration. You can't get those in the Q70. In addition to all of those positives, the A6 has a lower base price than the Q70, making it the clear choice.

Which Is Better: Infiniti Q70 or Mercedes-Benz E-Class?

The Mercedes-Benz E-Class is probably the most luxurious car in the segment. It offers pretty much any feature you can name, and still feels fresh and modern off its 2017 full redesign. The E-Class' performance mostly focuses on comfort, but there are bona-fide high-performance AMG versions available. You can also get the E-Class as a coupe, convertible, or wagon. This Mercedes starts at about $2,500 more than the Q70, which makes it the highest-priced nonhybrid in the class. It's worth every penny, though.

Which Is Better: Infiniti Q70 Hybrid or Lexus GS 450h?

If you were interested in the Q70's hybrid version, you're better off considering the Lexus GS Hybrid instead. Both cars get great fuel economy estimates and deliver sporty handling. The GS Hybrid ups the ante with its available F Sport trim, which adds an adaptive suspension and dynamic rear steering. Inside, the GS Hybrid really wows; its interior is comfortable and well-built, with lots of premium materials. Lexus' infotainment system is better as well. The main incentive for buying the Q70 Hybrid instead of the GS Hybrid is price: you'd save several thousand dollars with the Infiniti, but it's not as good a car.

Q70 Interior

How Many People Does the Q70 Seat?

Up to five people can fit in the 2018 Q70. Leatherette upholstery and heated, power-adjustable front seats are standard, while leather-appointed seats, semi-aniline leather upholstery, ventilated front seats, and a heated steering wheel are available. Both rows of seats are comfortable and roomy in the standard-wheelbase Q70, while the long-wheelbase Q70L has incredibly spacious rear seats with several extra inches of legroom. Unlike many long-wheelbase competitors, the Q70L does not offer more luxury features in the rear seat, like separate climate controls or entertainment screens.

Q70 and Car Seats

There are full sets of LATCH child-seat connectors on the outboard rear seats, along with an additional upper tether anchor on the middle rear seat. The lower anchors are buried deep in the seats, and clipping in car seats takes more elbow grease than you’d expect. Due to these challenges, the Insurance Institute for Highway Safety gave the Q70’s LATCH system a Poor rating for ease of use.

Q70 Interior Quality

High-end materials line the Q70's cabin. The styling is attractive but a bit outdated compared to the modern designs in many rivals. 

Q70 Cargo Space

There's 14.9 cubic feet of room in the Q70's trunk, which is slightly more than the class average. Q70 Hybrid models only have 11.3 cubic feet of cargo room. Carrying bulky items can be difficult, as the trunk is very narrow between the wheel wells and the rear seats don't fold.

Q70 Infotainment, Bluetooth, and Navigation

While there are numerous tech features in the Q70, you may be disappointed that they're not quite as advanced as those in many rivals. The infotainment system in particular is very outdated, with low-quality graphics and only basic features. Many competitors offer handwriting recognition or smartphone integration via Android Auto and Apple CarPlay. For more information, read What Is Apple CarPlay? and What Is Android Auto?

Q70 Performance

Q70 Engine: Plenty of Power

The base Q70 3.7 Luxe is powered by a V6 engine, while the Q70 5.6 Luxe has a V8. The Q70 Hybrid features a V6 paired with an electric motor. The V8 is by far the most potent, and it provides quick acceleration. Still, the standard V6 and hybrid powertrain are both satisfactory. A seven-speed automatic transmission comes with all three power plants.

Q70 Gas Mileage: Rivals Are More Fuel-Efficient

Most rivals get better gas mileage than the rear-drive Q70, which earns 18 mpg in the city and 25 mpg on the highway with the base V6. Hybrid models are significantly more fuel-efficient, getting up to 28 mpg in the city and 33 mpg on the highway.

Q70 Ride and Handling: Sporty Yet Smooth

Most buyers in this class value ride comfort and nimble handling, and the Q70 does both fairly well. Rough patches of pavement are smoothed out by the suspension. Around turns, the Q70 feels reasonably athletic. Models with the Sport package are very agile, but the firmer suspension and larger wheels can make the ride uncomfortable. The Q70's power steering makes slow-speed maneuvering an easy task, yet it doesn't feel too light at higher speeds. Rear-wheel drive is standard and all-wheel drive is available.

Which Infiniti Q70 Model Is Right for Me?

All of the Q70's features are available in the base 3.7 Luxe trim, so unless you need more engine power or desire the hybrid's better gas mileage, you should stick with the cheapest model. Even if you add all of the option packages to the base model, you'll still pay thousands of dollars less than you would for the V8-powered 5.6 Luxe trim.

Infiniti Q70 3.7 Luxe

The base Q70 3.7 Luxe starts at $50,300 (long-wheelbase models cost $1,500 more) and comes equipped with a V6 engine, an automatic transmission, rear-wheel drive, a moonroof, automatic headlights, rain-sensing wipers, push-button start, leatherette upholstery, power-adjustable front seats, heated front seats, dual-zone automatic climate control, a six-speaker audio system, satellite radio, and a rearview camera.

All-wheel drive is available for $2,150. The no-cost Essential package adds leather upholstery, ventilated front seats, a heated steering wheel, a 10-speaker Bose audio system, an 8-inch touch-screen infotainment system, navigation, front and rear parking sensors, and a 360-degree camera. 

The Sport package ($4,900) comes with a sport-tuned suspension, performance brakes, steering wheel-mounted paddle shifters, sport front seats, a 16-speaker Bose surround-sound system, and unique styling elements. The ProActive package ($3,300) adds adaptive cruise control, forward collision warning, automatic emergency braking, blind spot monitoring, and active lane keep assist.

Infiniti Q70 5.6 Luxe

The Q70 5.6 Luxe is priced at $63,350 (long-wheelbase models cost $1,700 more) and has a V8 engine, an automatic transmission, rear-wheel drive, leather upholstery, ventilated front seats, a 10-speaker Bose audio system, an 8-inch touch-screen infotainment system, navigation, front and rear parking sensors, and a 360-degree camera.

All-wheel drive is available for $2,550. The Sport and ProActive packages from the 3.7 Luxe model are available with this trim for the same price.

Infiniti Q70 Hybrid Luxe

The Q70 Hybrid Luxe costs $56,400 and has a V6 engine paired with an electric motor and the same standard features as the 3.7 Luxe trim.

The no-cost Essential package from the base trim is also available with the hybrid model. The Sensory package ($3,900) comes with upgraded leather upholstery, a 16-speaker Bose surround-sound system, and unique styling elements. The ProActive package is also available in this model for the same price as above.

The Final Call

There's plenty to like about the 2018 Q70, such as its range of powerful engines, comfortable yet nimble handling, and strong predicted reliability rating. The Q70 has lots of standard and optional features too. However, many competitors offer cabins that are more elegant and more technologically modern than the Q70's dated interior.

Don’t just take our word for it. Check out comments from some of the reviews that drive our rankings and analysis.

  • "This generation of the Q70 dates back to 2011, back when Infiniti called it the M56. There have been some updates over the years, but this is a very long time in the luxury sedan segment to go without a full redesign. Though spacious, the interior comes up short on storage and aesthetic appeal, and the touchscreen entertainment system feels ancient compared to the standard set by current luxury offerings." -- Edmunds
  • As the flagship sedan, the Q70 must not only do battle with more technically sophisticated models such as the BMW 5 Series and Cadillac CT6, but also newer makes like the Genesis G80. … Long-wheelbase models offer impressive rear-seat legroom, and all Q70s are loaded with the company's best technology and performance equipment. Still, in a space crowded with competitors like the Audi A6, BMW 5 Series, Lexus GS and Cadillac CT6, the Q70 won't always come in first place." -- Kelley Blue Book (2017)
  • "In the 2016 Infiniti Q70, you'll find a midsize luxury performance sedan on par with the best BMW, Audi and Cadillac sedans but with more expressive styling." -- Autotrader (2016)
