Engine options for the 2015 Q50
For 2014–2015, the Q50 used the 3.7L VQ37VHR or a hybrid 3.5L. The 2.0t and 3.0t engines arrived for 2016, so a later Q50 engine is a different design.
| Engine | Type and transmission | Before you request a replacement |
|---|---|---|
| 3.7L V6 (VQ37VHR) | Gas · 7-speed automatic · RWD or AWD | Match the VQ37VHR code and drivetrain. Ask what accessories are attached. |
| 3.5L hybrid V6 (VQ35HR) | Hybrid · 7-speed automatic | Hybrid-specific. Call to discuss sourcing. |
The VQ37VHR family was used in other Infiniti and Nissan models; match by engine code and application. Sources: Infiniti Q50 (Wikipedia).
Why 2015 matters
For 2016, Infiniti replaced the 3.7L with the 2.0t and 3.0t turbo engines. A 2016+ Q50 engine is not a swap for your 2015.

Match the code.
A used 2015 Infiniti Q50 engine has to match the engine your car was built with: the 3.7L VQ37VHR V6 or, in the Q50 Hybrid, the 3.5L hybrid V6. Confirm the VIN, engine code and what is included before you order.
The VQ37VHR was used in other Infiniti and Nissan models, but accessories and calibration differ. Match the engine code and application.
