How the engine fits this car

Offered in the Q50's first two model years before the turbocharged VR30 became the standard engine — this is the same well-proven VQ37VHR covered in detail on the G37's page.

A naturally aspirated six with a long, strong documented track record, genuinely lower-risk than betting on a comparatively newer turbo design.

Infiniti Q50-specific pros and cons

This is about the car itself — for engine-specific failure points, see the dedicated engine page below.

WHAT HOLDS UP WELL

  • VQ37's exceptional reliability reputation, detailed on its own page, is among the strongest in this catalogue
  • No turbo-related wear points to consider at all
  • Smooth, genuinely satisfying naturally aspirated power delivery
  • Strong specialist knowledge given this engine's long service across Infiniti's lineup

WHAT TO WATCH

  • Only offered in the first two model years, which limits how many are on the used market
  • Less outright torque than the turbocharged VR30 that replaced it
  • Minor oil consumption has been reported on a smaller subset of examples
  • Fuel economy is modest for a naturally aspirated six by modern standards

Pre-purchase checklist for this generation

Beyond general maintenance history, there's little engine-specific risk to flag.

Ask for documented oil change history given this engine's high-revving nature.

Confirm the model year, since this engine was only offered briefly before the turbo VR30 took over.
