2017 Infiniti Q50 Overview

Is the 2017 Infiniti Q50 a Good Used Car?

The Infiniti Q50 isn’t a great pick if you’re shopping for a used luxury small car. The Q50 trails its top classmates like the 2017 Audi A4 and 2017 BMW 3 Series with interior styling that’s long in the tooth, a complex infotainment system, and below-average predicted reliability. Its driving dynamics are pleasant but unremarkable in this sporty class, and its fuel economy is merely average. The Q50 fails to stands out in such a fiercely competitive segment. No matter what you’re looking for, you’re likely to be happier with other options in this class.

How Much Does the 2017 Infiniti Q50 Cost to Own?

The Infiniti Q50’s five-year costs for gas, insurance, repairs, and maintenance are projected to be $28,300 – or around $5,650 per year. That’s about average for the luxury small car class.

Is It Better to Buy a Used or New Q50?

The 2018 Infiniti Q50 starts at $35,200. Though it’s not a standout in this segment, you can save thousands of dollars by shopping for a used 2017 Q50, especially if you want a base model with few options. You won’t miss out on any features by sticking with a used model, either. For 2018, the Q50 received slightly revised exterior styling and renamed trim levels.

For a less expensive new sports sedan, consider the 2018 Mazda6, which starts at just $21,950. The Mazda6 may be a non-luxury midsize car, but its handsome interior and quality materials put quite a few luxury cars to shame. It offers agile handling and an easier-to-use infotainment system than the Q50, and it yields higher fuel economy (up to 26/35 mpg). That said, its engine performance can’t match that of the Infiniti’s stronger twin-turbo V6 engines.

Which Model Year of the Infiniti Q50 Is Best?

The first-generation Infiniti Q50 debuted for the 2014 model year. It replaced the 2013 G37 sedan. There have been few updates to the Q50 over this generation, but the most substantial changes arrived for 2016. These include a new four-cylinder engine for base models, two turbocharged V6 engines for higher trims (replacing one naturally aspirated V6), and an available adaptive suspension. For the absolute best performance in this lineup, stick with the 2016-and-newer models for their 400-horsepower V6 Red Sport variants. If you can do with a bit less power, consider saving money with an earlier 2014 and 2015 model that has comparable tech features.

2017 Infiniti Q50 Recalls

At the time of this writing, there are three recalls for the 2017 Q50. Infiniti is recalling certain models due to faults with the car’s fuel pump module, which could cause the car to stall. Two recalls target separate issues with the Q50’s front airbags, which may not properly deploy in the event of a crash. Before buying a used Q50, make sure these recalls have been addressed.

Which Used Infiniti Q50 Model Is Right for Me?

The 2017 Q50 sedan comes in a dizzying array of trim levels, but there are really just four core models to choose from: 2.0t, 3.0t, Red Sport 400, and Hybrid. Each of these models comes with a specific engine. The Q50 2.0t has 208 horsepower, the Q50 3.0t has 300 horsepower, the Q50 Red Sport has 400 horsepower, and the Q50 Hybrid has 360 horsepower. You'll want to skip the base 2.0t model. Its engine provides unimpressive performance. Instead, consider the 3.0t.

Regardless of what’s under the hood, all come with roughly the same standard features. These include a dual touch-screen infotainment system, a rearview camera, Bluetooth, USB ports, satellite radio, a CD player, keyless entry, push-button start, cruise control, dual-zone automatic climate control, leatherette upholstery, rain-sensing windshield wipers, and alloy wheels.

Available features include a moonroof, navigation, Bose stereo, heated front seats, leather upholstery, and the Technology package (suite of active safety features).

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 70,000 miles. Eligibility is determined by the vehicle’s initial sale 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. Infiniti CPO vehicles also receive free maintenance for one year. Additional benefits like towing, roadside assistance, and trip interruption coverage may be available, so read the Infiniti warranty page carefully.

Infiniti has one of the better CPO programs in the industry, according to our analysis. Lexus, Tesla, and Jaguar are among the very few that are better.

2017 Infiniti Q50 Versus the Competition

Which Is Better: 2017 Infiniti Q50 or 2017 Audi A4?

The 2017 Audi A4 is one of the best luxury small cars you can buy, with good reason. It has arguably the nicest interior in the class. Both rows of seats are spacious, and they provide all-day comfort. The A4 has an abundance of standard features, including Apple CarPlay and Android Auto smartphone integration, which you can’t get in the Q50. There are also plenty of driver assistance features, and the A4 performs admirably in crash tests. The Audi has peppy engine performance, agile handling, a comfortable ride, and better fuel economy than the Q50. Factor in the A4’s comparable ownership costs, and it’s a superior pick.

Which Is Better: 2017 Infiniti Q50 or 2017 BMW 3 Series?

The 2017 BMW 3 Series also tops the Infiniti, especially when it comes to driving dynamics. It has several engine options, ranging from potent four-cylinders to a 425-horsepower six-cylinder in the racy M3. On winding roads, the 3 Series feels comfortable yet more composed than the Q50. The BMW also gets better gas mileage. It further outshines the Infiniti with a higher-quality interior, comfier seats, and a simpler infotainment system. Go with the BMW.

Which Is Better: 2017 Infiniti Q50 or 2017 Infiniti Q60?

The Infiniti Q60 is the two-door-coupe sibling of the four-door Q50 sedan. Both cars share the same four-cylinder and V6 engine lineup, and each delivers refined – albeit not class-leading – handling. The catch is that the Q60 has all of the Q50’s quirks, and then some. Both cars have the same dated interior styling and cumbersome infotainment system. However, the Q60 has even less rear-seat space. Neither is a great option in the class.

2017 Q50 Performance

How Does the 2017 Infiniti Q50 Drive?

The Infiniti Q50 is available with four engine options: a turbocharged four-cylinder with 208 horsepower (2.0t), a pair of twin-turbocharged V6s with 300- and 400 horsepower (3.0t and Red Sport), and a V6 hybrid with 360 horsepower. A seven-speed automatic transmission and rear-wheel drive are standard; all-wheel drive is available.

The Q50’s twin-turbo V6 engines are the best of this bunch. Both hustle the sedan up to speed briskly and supply ample passing power. They also mesh nicely with Infiniti’s seven-speed automatic transmission, which delivers prompt shifts. The Q50 Hybrid isn’t as exciting, but it accelerates with confidence of its own. On the other hand, the Q50 2.0t just doesn’t measure up. It feels wheezy and unrefined under hard acceleration, and it struggles to heave the Q50 up to speed.

The Q50’s driving dynamics walk the line between comfy and sporty. This luxury sedan remains stable around corners, with precise steering and brakes that stop the car assertively. Its suspension also shrugs off most bumps and dips without creating a jarring ride.

Two high-tech systems are available to tailor the Q50’s handling, but only one is worth considering. The Q50’s Dynamic Digital Suspension (available on 3.0t and Red Sport 400 models) can electronically adjust to provide a softer ride when cruising the open road, or switch to a firmer ride for tackling corners. The Direct Adaptive Steering system isn’t as successful, as it feels a little too light and artificial for a sport sedan.

Does the 2017 Infiniti Q50 Get Good Gas Mileage?

The Q50 gets average fuel economy for the luxury small car class. The 2.0t model returns up to 23 mpg in the city and 31 mpg on the highway. The 3.0t returns 20/29 mpg city/highway, and Red Sport 400 models get 20/26 mpg city/highway. The Q50 Hybrid is the greenest, with a 27/32 mpg rating.

2017 Q50 Interior

How Many People Does the 2017 Q50 Seat?

The Infiniti Q50 is a four-door sedan that seats five. The front seats are roomy, and they provide ample head- and legroom for taller drivers and passengers. The rear seats are stingier on legroom – as is common in this class – though two average-sized adults can fit in the back comfortably on shorter trips. Leatherette upholstery is standard; heated and leather seats are available. The Q50’s cabin is quiet and features plenty of quality materials. However, it doesn’t match the quality you’ll find inside rivals like the 2017 Audi A4 and 2017 Mercedes-Benz C-Class. Its styling also looks rather out-of-date and stale by comparison.

How Many Car Seats Fit in the 2017 Infiniti Q50?

The Q50 has two full sets of LATCH connectors for securing child car seats.

2017 Infiniti Q50 Features

Standard features include two touch screens, a rearview camera, Bluetooth, USB ports, a CD player, and satellite radio. A 16-speaker Bose stereo and a navigation system are available.

The dual-screen infotainment system is an uncommon setup, and it’s not very user-friendly. The upper 8-inch screen displays the rearview camera and navigation functions, while the lower 7-inch screen manages audio and climate controls, as well as other multimedia functions. There are also dashboard buttons to manage these functions, and a rotary dial on the center console controls the top screen as well. Though the screens react quickly to inputs, the system feels clunky to use because of its haphazard control layout.
