  • Robust, powerful V6 engine
  • Lively handling
  • Upscale cabin materials
  • Roomy back seat
  • Complicated dual-screen infotainment system
  • Lower fuel economy estimates than many rivals

2015 Infiniti Q50 Overview

Is the 2015 Infiniti Q50 a Good Used Car?

The 2015 Infiniti Q50 is a good luxury small car, but only for buyers who prioritize performance. It has a strong V6 engine and agile handling, but unfortunately, the Q50 is quite the gas guzzler. The Q50 has sporty handling, but only in models that lack the available adaptive steering system, which offers little feedback from the road. Additionally, the Q50's dual-screen infotainment system is unnecessarily complicated compared to the more-intuitive systems found in rivals.

How Much Does the 2015 Infiniti Q50 Cost to Own?

Expenses for fuel, insurance, maintenance, and repairs for the 2015 Infiniti Q50 are estimated to be $30,600 over five years, or about $6,120 per year. That’s about average for a luxury small car.

Is It Better to Buy a Used or New Infiniti Q50?

Pricing for a new 2019 Infiniti Q50 ranges from $35,650 for the base model up to $53,350 for the top performance trim. For 2019, predictive forward collision warning and forward emergency braking became standard, and the hybrid powertrain was discontinued. That said, these safety features have been available in the Q50 since the model was introduced for 2014. If you shop around, you’re likely to save a significant amount of money and still find a used model that includes these features.

There are few new luxury small cars with starting prices around the average price of a used 2015 Q50 ($23,600). The 2019 Acura ILX starts at $25,900 and is the most affordable car you’ll get within the segment. However, it’s one of the lowest-ranked cars in the class, in part because of its weak base engine, complicated dashboard layout, and cramped seats.

If you don’t mind driving a nonluxury car, there are numerous appealing options. The redesigned 2019 Mazda3 has a modern, luxury-like interior, even in base models. The higher trims are even more upscale inside. On the performance front, the Mazda3 has zippy acceleration, sharp handling, and an extremely cushioned ride. Pricing starts at $21,000.

Which Model Year of the Infiniti Q50 Is Best?

Infiniti launched the Q50 for the 2014 model year, and as of this writing, it has yet to be redesigned. There were no major changes for 2015, so you can potentially save some cash by purchasing a comparably equipped 2014 model. However, there were significant updates for the 2016 model year to keep in mind, including an updated steering system and added engine options. For 2017, Infiniti expanded the sedan’s trim levels, and a 16-speaker Bose stereo became available.

Which Used Infiniti Q50 Model Is Right for Me?

The Q50 comes in three trims: base, Premium, and S. All models come with a 3.7-liter V6 engine, a seven-speed automatic transmission, and rear-wheel drive. All-wheel drive is available. A Q50 Hybrid model is also available, which we review separately.

The base Q50 is an excellent value. It comes loaded with a healthy dose of standard features, including synthetic leather upholstery, proximity keyless entry, dual-zone automatic climate control, two touch screens, Bluetooth, two USB ports, a six-speaker stereo, satellite radio, eight-way power-adjustable front seats, and push-button start.

The Premium trim adds heated front seats, a sunroof, and a 14-speaker Bose stereo. This trim has tons of available features, including a navigation system, adaptive steering, rain-sensing windshield wipers, adaptive headlights, a surround-view parking camera system, front and rear parking sensors, adaptive cruise control, distance control assist, forward emergency braking, lane departure warning, lane departure prevention, blind spot warning, predictive forward collision warning, and cross traffic alert.

The Q50 S is the performance-focused sport trim. It adds paddle shifters, genuine leather-trimmed sport seats, and aluminum pedals. The S is available with the same options as the Q50 Premium trim.

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.

2015 Infiniti Q50 Versus the Competition

Which Is Better: 2015 Infiniti Q50 or 2015 Mercedes-Benz C-Class?

The 2015 Mercedes-Benz C-Class is more comfort-focused than the athletic Q50. Still, the C-Class feels composed around corners, so it’s a better option for those who want a balance between sportiness and comfort. The Mercedes has a few available engines, including a powerful base turbocharged four-cylinder that gets better gas mileage than the Q5’s thirsty V6. The Mercedes-Benz C-Class also has one of the most sumptuous interiors in the segment. We named the C-Class our 2015 Best Upscale Small Car for Families. Still, both cars share one major flaw: complicated infotainment systems.

Which Is Better: 2015 Infiniti Q50 or 2015 Audi A3?

The 2015 Audi A3 has a few key advantages over the Q50, aside from being named our 2015 Best Upscale Small Car for the Money. The A3 features a lineup of strong engines that are more fuel-efficient than the Infiniti’s V6. Additionally, the A3’s infotainment system is more user-friendly. Still, the Audi has a below-average reliability rating, which lands it several places lower than the Q50 in our class rankings. Compared to its rival, the A3 also has smaller back seats and less trunk space. 

Which Is Better: 2015 Infiniti Q50 or 2015 Infiniti Q50 Hybrid?

If you like many of the Infiniti Q50’s attributes but are hesitant to buy because of its poor fuel economy estimates, the 2015 Infiniti Q50 Hybrid may be the solution. It returns 8 more mpg combined city/highway than the nonhybrid model. The Q50 Hybrid’s average list price is a few thousand dollars higher than that of its gas-only counterpart, but it also comes with more standard amenities like leather upholstery, heated front seats, and a moonroof. Though it gets better gas mileage estimates and offers more standard features, the Q50 Hybrid isn't as good of a car as the Q50 overall. The nonhybrid version has superior handling, smoother brakes, and a bit more cargo space than the hybrid variant.

2015 Infiniti Q50 Performance

How Does the 2015 Infiniti Q50 Drive?

The Infiniti Q50 has a potent V6 engine that produces 328 horsepower. It helps the Q50 deliver rapid acceleration from a stop and offers plenty of oomph at highway speeds. Rear-wheel drive and a seven-speed automatic transmission are standard; all-wheel drive is available.

This Japanese luxury sedan has nimble handling and strong brakes. Even better, its sporty ride doesn’t compromise ride comfort. That said, the available adaptive steering system isn’t as responsive as the standard setup. 

Does the 2015 Infiniti Q50 Get Good Gas Mileage?

With its powerful V6 base engine, the 2015 Infiniti Q50 gets below-average fuel economy for the class. The RWD models earns an EPA-estimated 20 mpg in the city and 29 mpg on the highway, and AWD models return 19/27 mpg city/highway.

2015 Infiniti Q50 Interior

How Many People Does the 2015 Infiniti Q50 Seat?

The 2015 Infiniti Q50 is a five-seat luxury small car. Its hushed cabin features sleek styling and premium materials, including standard synthetic leather upholstery. Eight-way power-adjustable front seats are standard. Genuine leather upholstery, a heated steering wheel, heated front seats, and front sport seats with two memory settings are available.

The front seats are spacious and supportive, and the sport seats provide even better support. Unlike several cars in the class, the Q50’s rear seats can comfortably accommodate a pair of tall adults.

How Many Car Seats Fit in the 2015 Infiniti Q50?

There are two full sets of LATCH child-seat connectors for the Q50's second-row outboard seats. You can also install a child safety seat in the middle-seat position by using that seat's tether connection and borrowing a lower anchor from an adjacent seat.

2015 Infiniti Q50 Features

Standard features include push-button start, dual-zone automatic climate control, Bluetooth, two USB ports, a six-speaker sound system, satellite radio and Infiniti’s InTouch infotainment system, which has an upper 8-inch touch screen and a lower 7-inch touch screen. Available features include a 14-speaker Bose sound system, navigation, and a moonroof.

The 2015 Q50’s InTouch infotainment system is different than most rivals’ standard setup, which typically includes a single touch screen flanked by buttons and knobs. Instead, the Q50’s system has buttons to control two separate display screens. Overall, the system seems disjointed and lacks cohesion.
