2018 Infiniti Q70 Review

The 2018 Infiniti Q70 has a comfortable interior, lively powertrains, and balanced handling. Drawbacks such as dated technology lower its overall appeal, however, sinking this sedan to the bottom half of our luxury midsize car rankings.

Pros & Cons

  • Spacious seats
  • Balanced, responsive handling
  • Energetic powertrains
  • Hybrid model gets good fuel economy
  • Tech features are meager and dated
  • Few opulent upgrades available
  • Nonhybrid models have below-average gas mileage ratings

Is the 2018 Infiniti Q70 a Good Used Car?

The Q70 is an OK entry-level luxury vehicle. In addition to the V6- and V8-powered models, this luxury midsize car is available as the Q70 Hybrid and the long-wheelbase Q70L.

The 2018 Q70 has some appealing qualities:

  • Roomy front seats with lots of power adjustments
  • Lots of rear-seat legroom in long-wheelbase Q70L models
  • Energetic engines
  • Good gas mileage with the hybrid model
  • Lower list prices than many rivals

But is held back by its shortcomings:

  • Upgraded infotainment system looks out-of-date and lacks modern features
  • Few first-class rear-seat upgrades available in Q70L models
  • Estimates for fuel and insurance expenses are well above the class average

Based on listings for the 2018 Infiniti Q70 on our site, the average list price is $34,100. Prices range from $25,800 to $43,000 and vary depending on the vehicle’s condition, mileage, features, and location.

How Much Does the 2018 Infiniti Q70 Cost to Own?

The 2018 Q70’s five-year costs for gas, insurance, repairs, and maintenance are projected to be about $31,860, or $6,372 per year. That’s above average for a luxury midsize car.

Is It Better to Buy a Used or New Q70?

For 2019, the Infiniti Q70 gains a ton of standard features, including navigation, a 10-speaker Bose premium sound system, leather-appointed seats, heated and cooled front seats, a 360-degree parking camera system, and parking sensors on the front and rear of the vehicle. That said, many of these same features were available for older models as free upgrades.

With prices for the 2019 Q70 starting at around $50,000 – well over the 2018 model's average list price of $34,000 – you may be able to save money by shopping for a used edition that's equipped with these upgrades. You'll also need to stick with a used model if you want a hybrid, as this powertrain was discontinued for 2019.

The Q70 gained the Luxe trim for 2018, but otherwise, this model was largely unchanged. You can likely spend less and still get virtually the same vehicle by opting for a 2016 or 2017 model instead of the 2018. The 2018 Q70 is part of a generation that debuted for the 2011 model year.

Which Used Infiniti Q70 Trim Is Right for Me?

The 2018 Infiniti Q70 comes as the V6-powered 3.7 Luxe, the V8-powered 5.6 Luxe, and the Hybrid Luxe. The Infiniti Q70L is a long-wheelbase model that's available with either the V6 or V8 engine. All models have an automatic transmission. The Q70L has an extra 5.6 inches of rear legroom and generally higher prices than the regular-wheelbase models. Rear-wheel drive is standard, and all-wheel drive is available for all but the hybrid model.

All three power sources are lively, leaving you open to decide between them. For the best value, search for a 3.7 Luxe trim with the Essential package. This nets you a solid engine and attractive goodies – such as leather seats and an upgraded infotainment system – for a reasonable price.

  • Infiniti Q70 3.7 Luxe: The base Q70 3.7 Luxe comes equipped with a V6 engine, a moonroof, fog lights, remote keyless entry, synthetic leather upholstery, a leather-wrapped steering wheel, power-adjustable front seats, heated front seats, dual-zone automatic climate control, a six-speaker audio system, satellite radio, rain-sensing windshield wipers, and a rearview camera.
    • The 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, a navigation system, front and rear parking sensors, and a 360-degree parking camera.
    • The Sport package comes with a sport-tuned suspension, performance brakes, steering wheel-mounted paddle shifters, front sport seats, a 16-speaker Bose surround-sound system, and unique styling elements.
    • The ProActive package adds adaptive cruise control, forward collision warning, automatic emergency braking, blind spot monitoring, and active lane keep assist.
  • Infiniti Q70 5.6 Luxe: The 5.6 Luxe has a V8 engine and all items from the Essential package. The Sport and ProActive packages from the 3.7 Luxe model are also available with this trim.
  • Infiniti Q70 Hybrid Luxe: The powertrain of the Q70 Hybrid Luxe includes a V6 engine, an electric motor, and a lithium-ion battery pack. It has the same standard features as the 3.7 Luxe trim, and is also available with the Essential package. The Sensory package comes with upgraded semi-aniline leather upholstery, a 16-speaker Bose surround-sound system, and unique styling elements. The ProActive package is also available in this model.

What Does Infiniti’s Certified Pre-Owned Warranty Cover?

Infiniti offers a certified pre-owned program for vehicles six years old or less, and with fewer than 75,000 miles. Eligibility is determined by the vehicle’s initial sale’s date. The Infiniti certified pre-owned warranty has three levels of coverage based on the vehicle’s age and mileage. Vehicles with less than 15,000 miles receive a six-year/75,000-mile warranty from the original new-car purchase date. Vehicles less than four years old with more than 15,000 miles receive a six-year/unlimited-mileage warranty from the original new-car purchase date. Finally, vehicles more than four years old with more than 15,000 miles receive a two-year/unlimited-mileage warranty good from the CPO purchase date. Infiniti CPO vehicles must pass a 167-point inspection. Additional benefits like towing and roadside assistance may be available, so read the Infiniti warranty page carefully.

According to our analysis, this level of coverage is typical for a luxury brand. Competing automakers with better CPO programs include Lexus and Volvo.

2018 Infiniti Q70 Versus the Competition

Which Is Better: 2018 Infiniti Q70 or 2018 Mercedes-Benz E-Class?

Among luxury midsize cars, the 2018 Mercedes-Benz E-Class stands out for its lavish interior and top-notch safety score. It was also a finalist for our 2018 Best Car for Families award. The average list price is about $20,000 higher than that of the Q70, but in exchange, you get quality cabin materials and lots of standard tech and safety features. Another option is to consider an E-Class from 2017 or earlier, which often have list prices in the $30,000 range.   

Which Is Better: 2018 Infiniti Q70 or 2018 Lexus ES?

It's difficult to recommend the Infiniti Q70 when the 2018 Lexus ES places so much higher in our rankings yet costs about the same to buy. It also has an outstanding predicted reliability rating and low predicted costs for fuel, insurance, and repairs (especially with the hybrid ES). Because of this stellar combination of quality and value, the Lexus ES won our 2018 Best Luxury Midsize Car for the Money award. If you like these attributes but want a higher level of performance, you can also consider the sportier 2018 Lexus GS.

2018 Q70 Performance

How Does the 2018 Infiniti Q70 Drive?

The Q70 is smooth and easy to drive. All three powertrain choices dispense a satisfying amount of power. The hybrid powertrain offers good fuel economy and faster off-the-line acceleration than the base V6, and the top-level V8 is muscular.

This sedan is agile, due in part to responsive steering and braking systems. Shoppers in search of a comfortable ride should go with the standard suspension, while a sport-tuned suspension is available for those wanting to dial up the performance a little.

  • Base engine: 330-horsepower 3.7-liter V6
  • Available powertrains:
    • 420-horsepower 5.6-liter V8
    • 360-horsepower hybrid powertrain with 3.5-liter V6 and an electric motor
  • Drivetrain: standard front-wheel drive; available all-wheel drive (nonhybrid models only)
  • Transmission: seven-speed automatic
Does the 2018 Infiniti Q70 Get Good Gas Mileage?

In the luxury midsize car class, the V6-powered Q70 has one of the lowest fuel economy ratings among base trims. Keep in mind that a number of rivals have four-cylinder base engines, which the Q70 lacks. 

  • 3.7-liter V6, RWD: 18/25 mpg city/highway
  • 5.6-liter V8, RWD: 16/24 mpg
  • Hybrid power system, RWD: 28/33 mpg

Models with all-wheel drive cost an average of $150 more to fuel each year versus their rear-wheel-drive counterparts.

2018 Q70 Interior

How Many People Does the 2018 Q70 Seat?

The 2018 Q70 seats five people. Its front seats have more legroom than most in the class, and the 10-way power adjustments make it easy to find a comfortable position. Rear-seat legroom is a little low in the regular models, and it grows by almost 6 inches in long-wheelbase Q70L models. This extra space is a welcome treat for stretching out, but this zone doesn't reach executive status, as it isn't available with premium upgrades like rear climate controls, cooling or massaging seats, or side window sunshades.

Standard seating features:

  • synthetic leather upholstery
  • 10-way power adjustable front seats
  • heated front seats

Available seating features:

  • leather upholstery
  • perforated semi-aniline leather seats
  • ventilated front seats
  • heated steering wheel
  • power rear sunshade
  • heated rear seats (Q70L only)
How Many Child Car Seats Fit in the 2018 Infiniti Q70?

The 2018 Q70 has two complete sets of LATCH car-seat connectors on the rear outboard seats and an upper tether on the rear middle seat. The hardware in the seat behind the driver is fairly easy to use, but the lower anchors on the opposite outboard seat are difficult to access and use. The Insurance Institute for Highway Safety gave the sedan's LATCH hardware the lowest rating of Poor for ease of use.

2018 Infiniti Q70 Features

The standard set of infotainment features in the Q70 is sparse for a luxury vehicle. Fortunately, many models come with the Essential package, which adds a touch screen, Bluetooth audio streaming, navigation, a better sound system, and more. However, even this uplevel technology has a dated appearance and is light on features.

  • Standard infotainment features: a six-speaker audio system, satellite radio, and Bluetooth for phone calls
  • Available infotainment features: the InTouch infotainment system, an 8-inch touch screen, a 10-speaker Bose audio system, a 16-speaker Bose surround-sound system, Bluetooth audio streaming, and a navigation system
  • Additional standard features: a moonroof, push-button start, and dual-zone automatic climate control

2018 Infiniti Q70 Dimensions

Infiniti Q70 Cargo Space

Both the Q70 and the long-wheelbase Q70L have a 14.9-cubic-foot trunk. That's a typical size for a luxury midsize sedan, and similar to rivals such as the 2018 Audi A6. The trunk's narrow shape and the lack of folding rear seats limits usability somewhat. Furthermore, no power-closing or hands-free trunk lid options are available.

Trunk space drops to 11.3 cubic feet in the hybrid, since the lithium-ion batteries occupy some of the luggage space.

These cargo dimensions are for comparative purposes. There is no substitute for visually examining the storage area in any car you’re considering.

2018 Infiniti Q70 Length and Weight
  • Length: 16 feet, 4.1 inches to 16 feet, 10 inches
  • Curb weight: 3,876 to 4,328 pounds
  • Gross vehicle weight rating: 4,993 to 5,423 pounds

Where Was the 2018 Infiniti Q70 Built?

Infiniti built the Q70 in Japan.
