The Infiniti Q70 has more engaging driving dynamics than most other luxury midsize sedans, but it ranks below average due to its overly firm ride and outdated cabin. 

Pros & Cons

  • Ride may be too firm for some
  • Poor trunk space


New for 2015


  • New long-wheelbase Q70L
  • Updated exterior styling
  • Revised interior features


2015 Infiniti Q70 Overview

Is the 2015 Infiniti Q70 a Good Used Car?

The 2015 Infiniti Q70's lively, sports-car-like handling around corners sets it apart from rival sedans. However, its corner-carving abilities lead to a firm ride, so you should consider other options if you prioritize ride comfort. Additionally, the QX70 lags behind rivals when it comes to cabin features and predicted reliability.

Used 2015 Infiniti Q70 Performance and Interior

The 2015 Infiniti Q70 comes standard with a 330-horsepower V6 engine that offers adequate acceleration for day-to-day driving. However, the available 420-horsepower V8 engine is the better option for peppy highway acceleration. The Infiniti Q70 Hybrid is equipped with an electric motor and a V6 engine that together provide 416 horsepower. A seven-speed automatic transmission is standard across Q70 models.

Thanks in part to its standard rear-wheel drive, the Q70 handles more like a sports car than a sedan. This makes it one of the more fun-to-drive cars in the luxury midsize class. You can further enhance the Q70's agility with an available sport-tuned suspension. However, the Q70's sporty handling comes at the expense of some ride comfort. The base Q70 gets an EPA-estimated 18 mpg in the city and 26 mpg on the highway, which is a bit low for a V6-powered sedan. The hybrid model, on the other hand, gets excellent estimates of 29 mpg in the city and 33 on the highway.

The Q70 has a good-looking cabin with quality materials. However, its technology and dashboard functions – though user-friendly – feel outdated compared to rivals’ more modern displays and gauge clusters. The 2015 Q70 seats five and has decent space and comfort in both rows. The long-wheelbase Q70L has ample rear-seat legroom for even the tallest passengers. Trunk space is on the low end for the class, with 14.9 cubic feet in the Q70 and Q70L and 11.3 cubic feet in the Q70 Hybrid. The Q70 has full sets of LATCH child-seat connectors on the rear outboard seats and an upper tether anchor on the rear middle seat.

Standard equipment includes a USB port, Bluetooth phone compatibility, a proximity key, and dual-zone automatic climate control. Available features include Bluetooth audio, a 10- or 16-speaker Bose stereo, navigation, an 8-inch touch screen, and numerous safety features.

Should I Consider Another Used Q70?

The Infiniti M, which began production with the 2007 model year, was renamed the Q70 in 2014. You can save money by shopping for a late-model Infiniti M, but it's best to stick to 2014 and newer Q70s for the most up-to-date features and styling. 2015 models received a new long-wheelbase version, updated exterior styling, and revised interior features.

Which Used Infiniti Q70 Is Right for Me?

Infiniti offers the Q70 in two trims: Q70 3.7 and Q70 5.6. The Q70 3.7 comes with a 330-horsepower V6 engine, while the Q70 5.6 has a 420-horsepower V8. Both come with a seven-speed automatic transmission and rear-wheel drive, while all-wheel drive is available. A long-wheelbase Q70L model with extra legroom is available with similar engines and features. A Q70 Hybrid is also available, offering more standard features and better fuel efficiency.

Opt for a Q70 5.6 model to get faster acceleration and more luxury and convenience features, like genuine leather surfaces, heated and cooled front seats, a 10-speaker Bose stereo, Bluetooth audio streaming, a surround-view camera, parking sensors, navigation, and voice recognition.

You should also consider a certified pre-owned Infiniti. 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.
