What Is the Infiniti Q50? The Q50 Nissan Explained
The Infiniti Q50 was introduced at the 2013 North American International Auto Show as a direct replacement for the beloved G37 sedan. It first went on sale in 2013 for the 2014 model year and made waves with its controversial steer-by-wire system, which received mostly negative reviews early on.

Engine & Performance: Q50 HP, Torque, and 0–60 MPH
The Q50’s engine lineup is one of the primary reasons enthusiasts still chase it on the used market. All versions of the Infiniti Q50 use a 3.0-liter twin-turbocharged V6 engine available in two power outputs — 300 or 400 horsepower. Infiniti
Standard 3.0T Engine (LUXE / SENSORY Trims): The Q50 LUXE and SENSORY produce 300 horsepower and 295 pound-feet of torque, with peak power delivered at 6,400 RPM and peak torque arriving as low as 1,500 RPM — meaning instant, usable pull from nearly any speed. Infiniti
Red Sport 400 Engine: The Q50 RED SPORT 400 pushes 400 horsepower and 350 pound-feet of torque. The full torque output arrives at 1,600 RPM, making the Red Sport 400 accelerate harder and longer than the standard tune. Infiniti The engine drives the rear wheels via a 7-speed automatic transmission, with power coming at 6,400 RPM and maximum torque held from 1,600 to 5,200 RPM — a remarkably wide band. Carfolio
0–60 MPH Performance: Most Q50 models sprint from 0–60 mph in approximately 5 seconds. The RED SPORT 400, however, covers that same distance in 4.5 seconds. Infiniti For reference, the BMW M340i achieves 0–60 mph in 3.7 seconds with 480 HP, while the Lexus IS 500 F Sport makes 472 HP Accio — placing the Red Sport 400 in credible but not class-leading territory.
Transmission & Drivetrain: Base trim levels pair the 300 HP twin-turbo with a 7-speed automatic transmission and rear-wheel drive, while the 400 HP Red Sport gains available all-wheel drive capability. Infinitiofsouthmiami Paddle shifters on the steering column allow manual gear selection in all trims.

Interior Tech & Comfort
Step inside the Q50 and the first thing you notice is the dual-touchscreen infotainment stack — a setup that was ahead of its time when it launched but has since aged into controversy. The Luxe trim arrives with an 8-inch upper touchscreen, a 7-inch lower touchscreen, Apple CarPlay, Android Auto, a heated steering wheel, a moonroof, and leather upholstery as standard features. CARFAX

Safety Suite & Crash Ratings
The Q50’s safety package is solid for its era, though it lagged behind some rivals in advanced ADAS by the time of its discontinuation. Every Q50 comes equipped with blind spot monitoring, rear cross-traffic alerts, forward collision warnings, automated emergency braking, and lane departure warning with lane-keeping assist.

Highway driving assistance is handled by Infiniti’s Intelligent Cruise Control, which monitors traffic flow and adjusts speed relative to the vehicle ahead. For in-depth federal safety ratings, visit the NHTSA official safety ratings database and the IIHS vehicle ratings page.
Fuel Efficiency & Real-World MPG
Fuel economy is where the Q50’s twin-turbo V6 extracts a modest penalty. The 2024 Infiniti Q50 offers up to 20 MPG in city driving and 29 MPG on the highway. Cars.com In mixed real-world driving, expect approximately 22–23 MPG combined. The Q50 requires premium unleaded gasoline rated at 91 octane or higher INFINITI, which adds ongoing fuel cost relative to regular-fuel competitors.

The Q50’s clearest advantage has always been raw power-for-money. The Q50 offers V6 power for the price of competitors’ four-cylinder engines, giving it an edge in outright acceleration while sacrificing fuel economy. U.S. News & World Report The Mercedes-Benz C-Class and BMW 3 Series both offer more modern tech and better refinement, but at higher prices or with significantly less standard power.
Driving Experience & Handling
Having spent time behind the wheel of both the standard 3.0T and the Red Sport 400 across urban commutes and open highways, the differences are dramatic. In city traffic, the standard 300 HP tune is perfectly civilized — the low-RPM torque delivery means never hunting for power at intersections. Throttle response is progressive, not snappy.
On the highway, the Red Sport 400 transforms entirely. When the 300 HP version flexes its muscles, acceleration is brisk, and the 7-speed automatic fires off smooth and decisive shifts. Everything gets amplified with the Red Sport 400. U.S. News & World Report The Dynamic Digital Suspension on the Red Sport adjusts damping in real-time, offering a notably flat cornering stance without sacrificing everyday comfort.
The Q50 drives with a secure, surefooted grasp of the road, though real driving enthusiasts may prefer to skip the electronic steering and stay with the standard hydraulic system, which delivers better road feel. U.S. News & World Report

Wait or Buy? 2024 Q50 vs. Shopping in 2026
This is the most important section for 2026 buyers. There is no 2025 or 2026 Q50 — the model is discontinued. The Q50’s spirit is intended to live on in a future sports sedan EV, previewed by the Vision Qe concept that debuted in late 2023. Motor1.com That EV replacement has no confirmed release date as of mid-2026.
So your decision is: buy a used Q50 now, or wait for an eventual replacement?
Buy Now If: You want a performance twin-turbo V6 sedan with proven reliability, AWD availability, and strong parts support through the Nissan/Infiniti dealer network — at a significantly depreciated price. Good-condition Red Sport 400 models are holding their value better than expected on the used market CarBuzz, but overall Q50 depreciation still makes them strong value plays.
Wait If: You prioritize modern infotainment, advanced ADAS, hybrid efficiency, or want a warranty-backed new vehicle. In that case, consider the Genesis G70, BMW 3 Series, or wait for Infiniti’s future EV sports sedan.

Q: Is the Q50 a Nissan Altima?
No. The Nissan Altima is a mainstream family sedan sold under the Nissan brand with four-cylinder engines starting well under $30,000. The Infiniti Q50 is a luxury performance sedan with a twin-turbocharged V6, starting at $43,000 when new — a very different car in segment, positioning, and capability.
Q: Which Nissans to stay away from?
This is model- and year-specific. For Infiniti/Nissan broadly, early Q50 models (2014–2015) with the 3.7L V6 are considered less exciting than the 3.0T twin-turbo models introduced in 2016. CVT-equipped Nissan vehicles sometimes draw reliability criticism in non-performance segments. Always check a vehicle history report via Carfax before purchasing.
Q: Is INFINITI basically a Nissan?
Yes — Infiniti is Nissan’s luxury brand, similar to how Lexus relates to Toyota or Acura to Honda. The Q50 was manufactured by Infiniti, the luxury vehicle division of the Nissan Motor Corporation. INFINITI The engineering, platforms, and global manufacturing are Nissan-rooted, but the products are engineered to distinct luxury specifications.
Q: Is an Infiniti Q50 a Nissan Maxima?

Q: Is a Q50 or Q60 faster?
They share the same 3.0T twin-turbo V6 platform, so performance specs are nearly identical. The Q60 was essentially the two-door coupe sibling of the Q50, offering similar looks and powertrain options in a sleeker, sportier package. Motor1.com The Q60 Red Sport 400 is marginally lighter, giving it a very slight edge in feel. The Q60 was discontinued after the 2022 model year, making it even rarer than the Q50 on today’s used market.
Q: What is the infiniti Q50 nissan skyline connection?
The Q50 was sold in Japan as the Nissan Skyline V37 generation, connecting it directly to one of automotive history’s most storied performance nameplates. The Skyline lineage includes the legendary GT-R bloodline, though the modern Q50/Skyline is a luxury performance sedan rather than a dedicated sports car.
Final Verdict
The Q50 Nissan — the Infiniti Q50 — is one of the most undervalued performance sedans on the 2026 used car market. Its twin-turbocharged V6 engine, particularly the Red Sport 400 variant, delivers genuinely exotic performance that remains relevant even against newer competition. The 4.5-second 0–60 time, 400 horsepower from a compact V6, and available AWD traction make this a compelling package at today’s depreciated prices.
Yes, the infotainment system is aging. Yes, pedestrian safety scores lag. And yes, there will be no 2026 refresh to look forward to. But for an enthusiast who values real-world driving engagement over touchscreen sophistication — and wants to spend $35,000–$45,000 on a certified pre-owned performance sedan with a known dealer network — the Q50 Red Sport 400 is a genuinely excellent choice.
If you’re buying for maximum practicality or technology, look at the Genesis G70, BMW 330i, or wait for Infiniti’s Vision Qe EV sedan. But if you want torque, character, and a twin-turbo V6 soundtrack for a reasonable price, the Q50 is hard to argue against.
