How much does the 2021 INFINITI Q50 cost?

Prices have softened 13.67% compared to this time last year, making it a favorable time to shop this model year.

There are 312 listings available, which gives you a modest amount of inventory to compare.

Is the 2021 INFINITI Q50 a good car?

Yes — the 2021 INFINITI Q50 earns a 4.5/5 user rating and a 6.8/10 expert rating. The standout strength is Look and feel at 8/10.

Owners consistently praise the powerful performance, classy interior, and sporty handling, and they also like how the car blends luxury with a more engaging driving feel. The main trade-offs are outdated technology and a cabin that can feel less refined than you might expect, especially when it comes to noise and feature content.

For you, that means the Q50 makes the most sense if you value style and driving character more than the newest cabin tech or maximum practicality. The market also shows 23.7% good or great deals, so there are still some attractive listings if you shop carefully.

Is the 2021 INFINITI Q50 reliable?

Owners rate it 4.5/5, a strong signal of long-term satisfaction.

The owner feedback points to a car that feels dependable and trouble-free over time, with many drivers saying they’d count on its strong performance and solid day-to-day behavior. The expert review also describes the Q50 as a solid choice as a discounted used car, which supports the idea that it can make sense for long-term ownership if you buy the right example.

Infiniti’s four-year, 60,000-mile basic warranty and six-year, 70,000-mile powertrain warranty were part of the ownership picture when new, which adds some reassurance for earlier-life coverage. For used buyers, the main long-term risk is that age-related wear and outdated tech can make a neglected example feel more expensive to live with than the price tag suggests.

What should I look for when buying a used 2021 INFINITI Q50?

At 55.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a pre-purchase inspection, especially if the car has been in a collision or shows signs of uneven wear. Focus on body condition, panel alignment, tire wear, brake feel, and whether the cabin electronics and driver-assist features work as expected. Because the Q50’s appeal depends so much on condition and equipment, a clean, well-kept example is worth more than one with a questionable past.

Key things to evaluate:

• Trim level: Pure is the entry point, while Luxe adds adaptive cruise control, blind-spot monitoring, lane-departure warning, and an Around View Monitor 360-degree camera system. Sensory and Red Sport 400 add a sportier-looking front bumper with larger air intakes and dual exhaust, and Red Sport models also get red brake calipers and 19-inch wheels. Pure and Luxe models have leatherette upholstery, so the higher trims are the ones to check if you want a more upscale feel.
• Powertrain: Every model uses a 3.0-liter twin-turbocharged V6 with a seven-speed automatic transmission. Most versions make 300 horsepower and 295 pound-feet of torque, while the Red Sport 400 makes 400 hp and 350 lb-ft. Rear-wheel drive and all-wheel drive are both available.
• Safety package: Forward-collision warning and automatic emergency braking are standard. Adaptive cruise control, blind-spot monitoring, lane-departure warning, and the Around View Monitor 360-degree camera system are added on the Luxe trim, and models with Direct Adaptive Steering also get Active Lane Control.
• Infotainment: The standard setup includes 8-inch upper and 7-inch lower touchscreens, Apple CarPlay/Android Auto smartphone connectivity, Bluetooth, and SiriusXM satellite radio. Sensory and Red Sport 400 models also get a 16-speaker Bose audio system.
• Fuel efficiency: Most rear-wheel-drive models are rated at 20 mpg city and 29 mpg highway, while all-wheel-drive versions are rated at 19 mpg city and 27 mpg highway. The Red Sport 400 is rated at 20 mpg city and 26 mpg highway with rear-wheel drive, and all-wheel drive lowers city fuel economy by 1 mpg.

Which 2021 INFINITI Q50 trim should I buy?

The 2021 INFINITI Q50 is offered in 4 trim levels: Pure, Luxe, Sensory, Red Sport 400.

Here's the short version:

• Pure: This is the entry point, and it gives you the core Q50 experience with the twin-turbo V6, standard safety basics, and the dual-screen infotainment setup. It makes sense if you want the lowest-cost way into the model, but you give up some of the convenience and driver-assist features that make the higher trims easier to live with.
• Luxe: This is the best-value trim for most shoppers because it adds adaptive cruise control, blind-spot monitoring, lane-departure warning, and the Around View Monitor 360-degree camera system. If you want the most balanced mix of equipment and price, this is the trim to target.
• Sensory: This trim adds a more upscale feel and includes the 16-speaker Bose audio system. It’s a good fit if you care more about comfort and cabin ambiance than chasing the highest-performance version.
• Red Sport 400: This is the performance-focused choice, with 400 horsepower, 350 pound-feet of torque, red brake calipers, 19-inch wheels, and a sportier exterior treatment. Choose it if you want the strongest acceleration and the most aggressive character.

The safety-package step-up happens at Luxe, so that’s the trim to watch if you want the most useful driver-assistance features without jumping all the way to the performance models.

Is now a good time to buy a used 2021 INFINITI Q50?

This is a moderate market for selective buyers, so you can find value if you compare listings carefully.

• Deal availability: 23.7% of listings are priced as good or great deals.
• Inventory: There are 312 listings available.
• Price trend: Prices have softened 13.67% compared with last year.
• Clean inventory: 55.8% of listings are accident-free.

If you find a listing below $20,612, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 INFINITI Q50's resale value?

The current average of $20,995 sits slightly below last year's $24,321.

That drop suggests the Q50 has already absorbed a meaningful amount of depreciation, which can help future sellers if they buy at the right price today. If you own one for a few years, the biggest resale advantage will come from keeping mileage reasonable and preserving condition, since buyers in this segment tend to reward clean examples with the right equipment.

The market still supports demand for well-kept cars like this one, especially when they have strong owner satisfaction and a desirable powertrain. Vehicles with strong owner satisfaction ratings, like this model year's 4.5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 INFINITI Q50 safe?

The 2021 Infiniti Q50 received top “Good” scores in all Insurance Institute for Highway Safety (IIHS) crash tests, but “Average” and “Marginal” ratings for headlights.

It earns a 6/10 safety score from our experts.

Forward-collision warning and automatic emergency braking are standard. If you move up from the base Pure trim to the Luxe trim, you also get adaptive cruise control, blind-spot monitoring, lane-departure warning, and an Around View Monitor 360-degree camera system. Models with Direct Adaptive Steering also get Active Lane Control.

The main caveat is that the Q50’s safety tech is solid but not especially advanced for the class, and the headlight ratings are a weak spot. That means you should pay close attention to trim level if safety equipment matters to you.

Should I buy a 2021 INFINITI Q50 or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 23.7% of listings are priced as good or great deals.
• At 55.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 13.67% compared with last year.
• Owners rate it 4.5/5 — a strong satisfaction signal.
• The 2021 model year added a new Sensory trim, more driver-assist tech, and a built-in WiFi hotspot.

The bottom line: If you want the freshest version of this generation with a better mix of features and a softer used-car price, the 2021 is the one to target. If you’re mainly shopping for the lowest entry price, a nearby year may still work, but you’ll want to compare equipment closely and prioritize condition over model-year differences.

How does the 2021 INFINITI Q50 compare to the 2021 BMW 3 Series?

Expert Pros & Cons (per CarGurus review team)

2021 INFINITI Q50:

• Pros: Stylish design, Powerful engine, Multiple powertrain options.
• Cons: Cramped back seat, Poor value for money, Outdated technology.

2021 BMW 3 Series:

• Pros: Multiple body styles, Great handling, Impressive technology.
• Cons: Advanced safety features are not standard.

Our experts score the 2021 INFINITI Q50 6.8/10 and the 2021 BMW 3 Series 6.8/10. The Q50 leans harder into style and straight-line power, while the 3 Series brings stronger handling and more impressive technology. If you care most about design and engine character, the Q50 has the edge; if you want a more modern-feeling luxury sedan, the BMW is the better fit. The Q50’s cramped back seat and dated tech are its biggest drawbacks against the BMW’s broader appeal.
