2017 Infiniti Q70 Review

The 2017 Infiniti Q70 sits toward the bottom of our luxury midsize sedan rankings. Its interior tech lags behind the competition, and its interior design looks dated. Although it has a lineup of powerful engines, the Q70’s sport-tuned suspension can make for an uncomfortable ride.

Pros & Cons

  • Composed handling
  • Fuel-efficient hybrid powertrain
  • Ample rear-seat legroom
  • Long features list
  • High predicted operating costs
  • Limited cargo space
  • Outdated cabin design
  • Occasionally stiff ride

2017 Infiniti Q70 Overview

Is the 2017 Infiniti Q70 a Good Used Car?

The Infiniti Q70 is average, but average isn’t enough in the competitive luxury midsize cars class. Nothing distinguishes its performance from its rivals. Like some competitors, it offers a capable base engine and a V8 option. It even has a hybrid variant with strong fuel economy, but so does one of its chief competitors, the 2017 Lexus GS 450h. The Q70’s interior is roomy, especially in long-wheelbase models, but challengers like the 2017 Genesis G80 deliver better standard features and modern interior designs. The Q70’s high predicted operating costs are another downside.

The 2018 Acura TLX (starting price $33,000) is the only new luxury midsize sedan with a lower price than the 2017 Q70’s average price. However, like the Q70, the TLX ranks low in its segment. Among new luxury small cars, the 2018 Kia Stinger (starting price $31,900) is worth consideration. The Stinger is large for the class, and it boasts head-turning style, potent engines, dynamic handling, straightforward tech features, and a large cargo area.

Which Model Year of the Infiniti Q70 Is Best?

You’ll likely save money with a 2014 Q70, but it’s slightly different from newer models. That’s because Infiniti refreshed the Q70’s exterior and interior styling for 2015, and it added a long-wheelbase Q70L version. With no major differences between the 2015 Q70, the 2016 Q70, and the 2017 version, the 2015 and 2016 models are good choices. However, it’s important to note that the Q70 ranks toward the bottom of its segment, regardless of the model year.

Which Used Infiniti Q70 Model Is Right for Me?

The 2017 Infiniti Q70 is available in three trim levels: 3.7, 5.6, and Hybrid. Each trim comes with a different engine. The Q70L, a long-wheelbase variant, is also available in nonhybrid trims.

Your best choice is the Q70 3.7 trim, with its V6 engine. Standard feature include 10-way power-adjustable heated front seats, dual-zone automatic climate control, push-button start, a 7-inch color info display, a USB port, Bluetooth, satellite radio, and a six-speaker Bose audio system.

Unless you crave the extra horsepower of the pricier Q70 5.6 trim, there’s little reason to spend more for the higher model. The Q70 5.6 trim has a stronger V8 engine, navigation, voice recognition, and climate controlled front seats. The Hybrid trim shares most of the features found in the Q70 3.7 trim.

Certified Pre-Owned Infiniti Q70 Warranty

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.

2017 Infiniti Q70 Versus the Competition

Which Is Better: 2017 Infiniti Q70 or 2017 Audi A6?

Like the 2017 Q70, the 2017 Audi A6 is a sporty luxury midsize sedan. The A6 is nimbler around corners than the Infiniti, but the Q70 has a stronger base V6. However, he Audi has a nicer interior with exquisite craftsmanship. Both models have comparable infotainment systems, though the A6 is available with both Apple CarPlay and Android Auto, while the Q70 offers neither. The A6 also offers tri-zone automatic climate control, while the Infiniti only comes with dual-zone. In the end, the Audi’s nicer interior makes it a better choice than the Q70.

Which Is Better: 2017 Infiniti Q70 or 2017 Genesis G80?

The 2017 Genesis G80 is one of our top-ranked luxury midsize sedans. The G80 has a high-quality interior that features full-grain leather seats, an elegant dash layout, and sophisticated technology. The Q70 has upscale materials too, but its interior looks dated compared to the Genesis. The G80 also has a much better infotainment system that comes standard with Apple CarPlay, Android Auto, and navigation.

Which Is Better: 2017 Infiniti Q70 or 2017 Lexus GS 450h?

The 2017 Lexus GS Hybrid (GS 450h) and the Q70 Hybrid get roughly the same fuel economy numbers. Beyond that, though, the Lexus is the better choice. The GS 450h offers a better interior than the Q70, and it wins the infotainment showdown with a larger 12.3-inch screen, more speakers, and Siri Eyes Free.

How Many People Does the 2017 Q70 Seat?

The 2017 Infiniti Q70 has seating for five on leatherette upholstery. Heated, 10-way power-adjustable front seats are standard. Heated rear seats and cooled front seats available on some models. Front and rear legroom are abundant, especially in the long-wheelbase Infiniti Q70L. This variant offers an extra 5.6 inches of rear-seat legroom.

How Many Car Seats Fit in the 2017 Infiniti Q70?

The Infiniti Q70 has two complete LATCH car-seat connectors in its rear outboard seats and a middle-seat tether anchor. The Insurance Institute for Highway Safety gave the Q70’s LATCH system the lowest rating of Poor. The lower anchors are too deep in the seats, and too much force is required to attach the tethers. On the passenger side, the lower anchors are difficult to attach and maneuver around.

2017 Infiniti Q70 Features

Standard features include an infotainment system with Bluetooth for phone calls and audio streaming, a USB port, satellite radio, steering wheel-mounted audio controls, a 7-inch display, a six-speaker audio system, and keyless entry.
