Is the 2015 Infiniti Q50 fast?
Yes. The 2015 Infiniti Q50 is quick for a luxury sedan, with its 328-hp 3.7-liter V6 and a seven-speed automatic; 0–60 mph generally lands around five seconds in the best configurations.
This article explains what makes the Q50 fast, how performance varies by drivetrain and trim, and how it compares to rivals from that period. It outlines the key specs, real-world feel, and the driving experience that informed its reputation for speed in the class.
Performance fundamentals
Core specifications shape how the Q50 accelerates and handles on the road. The 2015 model uses a 3.7-liter V6 producing 328 horsepower and 269 lb-ft of torque, paired with a seven-speed automatic transmission. Buyers could choose rear-wheel drive (RWD) or all-wheel drive (AWD), with sport-oriented tuning available on higher trims.
These elements translate into brisk acceleration and confident highway merging. In practical terms, the RWD version tends to feel quicker off the line, while AWD offers improved traction in poor conditions at the cost of a touch more weight and drivetrain loss.

Key performance details for perspective on speed:
In everyday driving, the Q50 offers a well-rounded blend of power and refinement. The engine’s mid-range pull makes overtaking easy, and the seven-speed gearbox is generally smooth and responsive, contributing to a perception of speed without sacrificing comfort.
Trims and driving characteristics
The 2015 Q50 came in several trims with shared powertrain but varying levels of sport-oriented tuning. The Sport-oriented variants included enhancements like upgraded suspension, more aggressive tires, and steering tweaks that sharpen turn-in and overall handling. While not a dedicated high-performance car, the Q50’s sport setup aimed to deliver a more decisive feel on winding roads and during quick maneuvers.
Real-world driving and comparisons
Compared with some rivals from its era, the Q50 delivers similar or better everyday acceleration in its class, with a focus on cabin comfort and refined highway cruising. Peak-lane performance is strong for daily driving and passing; however, there are rivals in the segment that offered quicker 0–60 figures in certain trims or with turbocharged powertrains. The Q50’s strengths lie in a balanced ride, solid brakes, and a premium interior that remains comfortable during spirited driving.
Summary
The 2015 Infiniti Q50 is fast by luxury-sedan standards, thanks to its 328-hp V6, a responsive seven-speed automatic, and the availability of sport-tuned handling. It delivers competitive 0–60 performance in roughly the low-to-mid five-second range depending on drivetrain and trim, making it a strong choice for buyers prioritizing speed with everyday comfort. It isn’t a track-focused sport sedan, but its blend of pace, refinement, and luxury positioning kept it competitive in its class for the model year.
Summary takeaway
For speed-conscious buyers shopping the 2015 Infiniti Q50, the key takeaway is that it offers solid, enjoyable acceleration without sacrificing ride quality. If outright cornering prowess and the absolute fastest 0–60 times are the goal, some rivals may edge it out; if you want a quick, refined luxury sedan with a strong V6, the Q50 fits the bill.
