The Infiniti Q50 is faster than the G35x in stock form, thanks to a more powerful engine and a modern drivetrain. In typical testing, the Q50 offers quicker acceleration and more responsive performance overall.
Below we compare the two models across core performance metrics, explain why the newer Q50 edges out the older G35x, and highlight practical considerations for everyday driving and ownership.
Performance snapshot
Before listing the key specs, it helps to know that the Q50’s combination of a larger, more modern V6 and a seven-speed automatic generally delivers quicker 0-60 mph times than the G35x’s older powertrain. The G35x, while a strong performer for its era, has lower peak horsepower and a older transmission design by comparison.
- G35x (2004–2006): 3.5L V6 around 278–280 hp, torque near 270 lb-ft, all-wheel drive. Typical 0–60 times are in the high 5s to low 6s range, depending on transmission and conditions.
- Q50 (2014–2019, base 3.7L): about 328 hp, around 267 lb-ft of torque, available with all-wheel drive (Q50x). Typical 0–60 times are roughly in the low to mid-5 seconds range for the standard models, again depending on drivetrain and year.
In summary, the Q50 is generally faster to 60 mph than the G35x in stock form, with a stronger modern engine and updated transmission contributing to quicker acceleration.
Why the Q50 is faster
Several design and technology advances help the Q50 outperform the G35x in straight-line acceleration and overall feel behind the wheel.
- Stronger, newer engine lineup: The Q50’s 3.7L V6 delivers more horsepower and a broader torque curve than the G35x’s 3.5L V6 used in its era.
- Updated transmission: The Q50 uses a more modern seven-speed automatic with refined shift logic, improving quickness and efficiency compared with the G35x’s older setup.
- Aerodynamics and chassis refinements: The Q50 benefits from a more modern platform, aiding efficiency and high-speed stability, which indirectly supports faster times.
Overall, these factors combine to give the Q50 a clear advantage in acceleration and everyday driving responsiveness over the G35x.
Real-world considerations
In practice, the faster feel of the Q50 depends on several variables beyond the base specifications. Tire condition, road surface, weather, and how well the car is maintained can noticeably affect performance. Additionally, different trims (including the performance-oriented Red Sport variants) dramatically change acceleration potential.
- Drivetrain choice: RWD versus AWD can influence launch feel and 0–60 timing, with AWD typically adding slight weight and altering traction.
- Model year and trim: Higher-output Q50 variants (and Red Sport models) are significantly quicker than the G35x, while early Q50s with base power may be closer to the G35x in some metrics.
- Maintenance and tires: Fresh tires and proper alignment can shave tenths off 0–60 times and improve everyday responsiveness.
For buyers choosing between the two today, the Q50 represents the faster modern option, with the G35x offering classic Infiniti styling and a solid used-car value, but typically slower acceleration by modern standards.
Summary
The Q50 is faster than the G35x in stock form, driven by more horsepower, a quicker-transmission setup, and newer engineering. While both cars deliver solid V6 performance, the Q50’s greater power and updated drivetrain translate to quicker responses and a more energetic drive. For enthusiasts prioritizing speed, the Q50 – including its sportier variants – is the clear choice over the G35x. If you’re considering used options, weigh the specific year, trim, and maintenance history to understand the real-world performance you’ll experience.
