2018 Infiniti Q50 Review

The 2018 Infiniti Q50 ranks in the lower half of the luxury small car class. While it has balanced handling, a comfortable cabin, and powerful engine options, it’s held back by its frustrating infotainment system and sparse amenities.

Pros & Cons

  • Powerful V6 engines
  • Athletic handling
  • Many available safety features
  • Mediocre gas mileage
  • Confusing infotainment system

Is the 2018 Infiniti Q50 a Good Used Car?

The Infiniti Q50 is a decent option if you’re shopping for a used luxury small car.

The 2018 Q50 sedan has many highlights:

  • Comfortable interior with seating for five
  • Agile handling
  • Powerful twin-turbo engine options
  • Low asking prices
  • Many available safety features

The Q50 does have several drawbacks though:

  • Distracting dual-screen infotainment system
  • No support for Apple CarPlay or Android Auto
  • Dated cabin styling
  • Mediocre fuel economy
  • Artificial response from available adaptive steering

If you’re looking for a luxury small car with better infotainment features and a ritzier cabin, consider alternatives like the 2018 Audi A4 and 2018 Kia Stinger.

You can save even more money by buying a used 2014 to 2017 Q50. These cars are all part of the same generation as the 2018 model, and they all share similar styling and many of the same features.

Which Used Infiniti Q50 Trim Is Right for Me?

The 2018 Infiniti Q50 is available in six trim levels: 2.0t Pure, 2.0t Luxe, 3.0t Luxe, 3.0t Sport, Red Sport 400, and Hybrid Luxe. The entry-level 2.0t Pure trim is short on amenities and performance for a luxury car. Upgrading to a 3.0t Luxe or Sport model remedies the performance issue, but a lot of safety and convenience features are still absent, such as heated seats and parking sensors. Look closely to see if the model you're interested in is equipped with these options – and others. These features are standard only in the top trim levels.

  • Infiniti Q50 2.0t Pure: The base model Q50 has a 208-horsepower turbo-four engine and a seven-speed automatic transmission; it’s available with either rear- or all-wheel drive. Standard features include a pair of touch screens, two USB ports, Bluetooth, satellite radio, a rearview camera, keyless entry, push-button start, dual-zone automatic climate control, synthetic leather upholstery, power-adjustable front seats, heated side mirrors, rain-sensing windshield wipers, and 17-inch alloy wheels.
  • Infiniti Q50 2.0t Luxe: The 2.0t Luxe trim has the same four-cylinder engine, but it adds a moonroof, interior wood trim, and 18-inch wheels.
  • Infiniti Q50 3.0t Luxe: The 3.0t Luxe trim shares the 2.0t features but includes a twin-turbocharged V6 engine with 300 horsepower. Rear- and all-wheel drive are available.
  • Infiniti Q50 3.0t Sport: The 3.0t Sport trim has the same V6 engine, but it adds leather seats, aluminum interior trim, and 19-inch wheels.
  • Infiniti Q50 Red Sport 400: The racy Red Sport trim adds a 400-horsepower V6 engine. Rear- and all-wheel drive are available. Additional standard features include a navigation system, remote start, heated front seats, a heated steering wheel, an adaptive suspension, upgraded brakes, blind spot monitoring, parking sensors, a 360-degree camera, and forward collision warning with brake assist.
  • Infiniti Q50 Hybrid Luxe: The Q50 Hybrid Luxe has a 360-horsepower hybrid system, and it’s available with rear- or all-wheel drive. It shares almost all of the Red Sport’s features, plus a Bose stereo, the Direct Adaptive Steering system, adaptive cruise control, lane departure warning, lane keep assist, adaptive headlights, and automatic high-beam headlights.

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’s 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/70,000-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.

Competitors like Lexus and Volvo have more comprehensive programs, according to our analysis.

2018 Infiniti Q50 Versus the Competition

Which Is Better: 2018 Infiniti Q50 or 2018 BMW 3 Series?

The 2018 BMW 3 Series is a better pick for most shoppers. The 3 Series has a higher quality interior, feels more athletic and fun to drive, and rewards drivers with a smoother ride quality. It has a wider array of potent engine options, including plug-in hybrid and turbodiesel variants, and these powertrains yield better fuel economy than their Q50 counterparts. BMW’s iDrive infotainment system is also much easier to use, and it supports the popular Apple CarPlay app. Used 3 Series models often command higher asking prices, but even so, it's the better buy.

Which Is Better: 2018 Infiniti Q50 or 2018 Lexus IS?

The 2018 Lexus IS is another attractive option in this segment. The IS has refined driving dynamics and zippy four- and six-cylinder engine options. The Lexus outshines the Infiniti with its ritzier cabin materials and longer list of standard safety features, like forward collision warning and automatic emergency braking. Both sedans have quirky infotainment systems and mediocre fuel economy, but the Lexus is a better package overall.

2018 Q50 Performance

How Does the 2018 Infiniti Q50 Drive?

The standard Q50 2.0t is capable but unexciting in everyday driving. Its four-cylinder engine scoots the car around town and up to speed respectably. The steering is responsive, and the car feels stable around turns. The suspension filters out most bumps and dips in the road, yielding a fairly comfortable ride. The Q50’s seven-speed automatic transmission changes gears smoothly, though it occasionally feels hesitant to downshift.

The Q50 starts to feel more like a sports sedan in its 3.0t and Red Sport trims. These models have punchy twin-turbocharged V6 engines that eagerly rocket the Infiniti up to speed and provide confident passing power. The hybrid powertrain delivers snappy acceleration as well.

That being said, you may want to skip some of the Q50’s performance-oriented options. The available Dynamic Digital Suspension system can quickly adjust the car’s shock absorbers, but this setup results in a firm ride on rough roads, even in its softest setting. It’s optional in 3.0t Sport models and standard in Red Sport models. The available Direct Adaptive Steering system also misses its mark. This electronic steering doesn’t deliver the same level of response and road feel as conventional systems.

  • Base engine: 208-horsepower 2.0-liter turbocharged four-cylinder (2.0t)
  • Available engines:
    • 300-horsepower 3.0-liter twin-turbo V6 (3.0t)
    • 400-horsepower 3.0-liter twin-turbo V6 (Red Sport)
  • Available powertrain: 3.5-liter V6 engine and an electric motor with a combined 360-horsepower (Hybrid)
  • Drivetrain: standard rear-wheel drive; available all-wheel drive
  • Transmission: seven-speed automatic
Does the 2018 Infiniti Q50 Get Good Gas Mileage?

The Q50 gets decent fuel economy for a luxury small car. The Q50 Hybrid is the most efficient powertrain in this lineup, but even it is outshined by hybrid and turbodiesel variants of the 2018 BMW 3 Series, Audi A3, and Jaguar XE.

  • 2.0t, RWD: 23/30 mpg city/highway
  • 2.0t, AWD: 22/28 mpg
  • 3.0t, RWD: 20/29 mpg
  • 3.0t, AWD: 19/27 mpg
  • Red Sport, RWD: 20/26 mpg
  • Red Sport, AWD: 19/26 mpg
  • Hybrid, RWD: 27/32 mpg
  • Hybrid, AWD: 26/30 mpg

2018 Q50 Interior

How Many People Does the 2018 Q50 Seat?

The Infiniti Q50 is a four-door sedan with five seats. The hip-hugging front seats are very supportive, and they remain comfortable over long road trips. There’s ample headroom and legroom up front, even for taller drivers and passengers. The rear seats aren’t as spacious, though there’s adequate room for adults to sit comfortably on shorter drives.

The Q50’s interior is trimmed with nice materials – wood and aluminum accents are available – and a number of surfaces are padded and soft to the touch. Overall though, the cabin doesn’t feel as luxurious as many segment rivals, and its styling has grown dated.

Standard seating features:

  • synthetic leather upholstery
  • power-adjustable front seats

Available seating features:

  • genuine leather upholstery
  • heated front seats
How Many Child Car Seats Fit in the 2018 Infiniti Q50?

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

2018 Infiniti Q50 Features

Every Q50 is equipped with Infiniti’s InTouch infotainment system, which pairs an upper 8-inch touch screen with a lower 7-inch touch screen. The top screen displays navigation, when equipped. The lower screen is used to configure vehicle settings, as well as adjust the audio and climate controls, though there are also buttons and knobs for these features. A dial on the center console and a toggle on the steering wheel can also be used to control the upper screen.

This dual-screen setup looks sleek, but its wide variety of controls can make it overwhelming to use. The lower screen in particular is also hard to see in direct sunlight. The system does not support Apple CarPlay or Android Auto either.

  • Standard infotainment features: 8- and 7-inch touch screens, Bluetooth, two USB ports, and satellite radio
  • Available infotainment features: a navigation system and a Bose stereo
  • Additional standard features: dual-zone automatic climate control, keyless entry, and push-button start
  • Other available features: remote start and a moonroof

2018 Infiniti Q50 Dimensions

Infiniti Q50 Cargo Space

The Q50 has just over 13 cubic feet of trunk space, which is average for a luxury small car. This is on par with competitors like the 2018 BMW 3 Series and 2018 Audi A4. The Q50 Hybrid has only 9.4 cubic feet of trunk space, though, due to the placement of its hybrid battery pack.

These cargo dimensions are for comparative purposes. There is no substitute for visually examining the storage area in any car you’re considering.

2018 Infiniti Q50 Length and Weight
  • Length: 15 feet, 10 inches
