Pros & Cons

  • Powerful available engines
  • Athletic handling
  • Ample passenger room
  • Class rivals are more reliable
  • Transmission hunts for right gear

2014 Infiniti Q70 Overview

Is the 2014 Infiniti Q70 a Good Used Car?

The new-for-2014 Q70's mediocre ranking doesn't tell the whole story – it has great overall performance for a midsize sedan, and its premium materials hit the mark for a luxury car. It also offers a spacious cabin with a long list of standard and available features.

Used 2014 Infiniti Q70 Performance and Interior

The 2014 Q70 is available with one of two engines, either a 330-horsepower 3.7-liter V6 or a 420-horsepower 5.6-liter V8. Both are mated to a seven-speed automatic transmission, with either rear- or all-wheel drive. Each powertrain delivers quick acceleration at higher speeds, but the transmission can be slow to downshift and hunts for gears at times. Fuel economy estimates range from 18 mpg in the city and 26 mpg on the highway for a base model with rear-wheel drive to 16/23 mpg city/highway for an AWD V8 model. The Q70 is also available as a hybrid, which gleans a decent 29 mpg in the city and 33 on the highway.

The Q70 also has impressive athletic handling. It can easily carve corners with its precise steering, and the brakes are strong. Some models may have performance upgrades like a sport suspension or sport brakes. The trade-off for the Q70's sporty character is a stiff ride quality, which not all luxury midsize car shoppers may be willing to overlook.

The Q70 seats five on standard leather and has power-adjustable, heated front seats. The driver enjoys a cockpit-like setup, with good outward visibility and a good amount of space throughout the cabin. Rear-seat passengers, in particular, should have ample leg- and headroom. The Q70 has two sets of LATCH child-seat anchors and three top tether anchors.

Standard features in the Q70 include dual-zone automatic climate control, rain-sensing windshield wipers, a moonroof, proximity keyless entry, push-button start, a USB port, satellite radio, Bluetooth, a rearview camera, and a 7-inch infotainment system. Available amenities include a heated steering wheel, a power rear sunshade, a 10- or 16-speaker Bose premium sound system, Bluetooth streaming audio, a DVD player, navigation, voice recognition, and rear parking sensors. The Q70's features are easy to use, and the elegantly designed cabin is awash in premium materials.

Should I Consider Another Used Q70?

The Infiniti Q70 sedan was an all-new model for 2014, though technically it was a renamed variant of the Infiniti M sedan. A 2014 Q70 will likely cost you less than a newer model, but buying the 2015 or 2016 Q70 is a better choice. The 2015 Q70 gained a long-wheelbase model and revised features, the 2016 Q70 was available with new driver assistance features, and both models received updated exterior styling.

Which Used Infiniti Q70 Is Right for Me?

The 2014 Infiniti Q70 is available in two major trims, denoting engine size: Q70 3.7 and Q70 5.6. Both models can be found with rear- or all-wheel drive, and a Q70 Hybrid is also available. It should be easy to find a Q70 to meet your needs – while the Q70 5.6 adds additional features such as ventilated seats, a Bose stereo, navigation, and Bluetooth streaming audio, all available features can be found in either model. Some amenities, like driver assistance technologies, were optional in the top trim when new, so you may have to hunt around for a model equipped with the features you desire. 

You may also want to consider a certified pre-owned Q70. The Infiniti certified pre-owned warranty has three levels of coverage based on the vehicle’s age and mileage. Infiniti 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, Infiniti 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.

2014 Infiniti Q70 and Other Cars to Consider

Which Is Better: 2014 Infiniti Q70 or 2014 Acura TL?

The 2014 Acura TL – the model’s last year of production – has better reliability ratings and a lower cost of ownership than the Q70, but those are its only outright advantages. The TL’s two available V6 engines are fairly powerful and offer a good balance of sport and comfort, but the Q70 has more power and better handling. Both cars offer good passenger space, but the Q70’s features are more modern. It offers a whole swath of driver assistance features (unlike the TL) and has an intuitive standard infotainment system. If you want a solid, reliable daily driver, the TL is a good pick that will save you thousands of dollars over the Q70. If you want a little more pep in your drive and have a bigger budget, the Q70 is a decent choice.

Which Is Better: 2014 Infiniti Q70 or 2014 Lexus GS?

If the Q70 is a good car, then the 2014 Lexus GS is a great car. The GS tops a very competitive class with its perfect reliability rating, high safety scores, and few flaws. The GS gets good performance from its sole V6 engine, and it delivers a soft ride with engaging handling. Inside, high-quality materials adorn a spacious cabin, and tall occupants should be comfortable wherever they sit. The list of standard and available features is comparable between these two luxury cars, but the Lexus earned criticism for its finicky infotainment controller. Still, the 2014 GS is a better choice than nearly all other cars in the class.
