Q50 Powertrain Guide — Know Your Engine Before Ordering
The Q50 has the most complex powertrain matrix of any INFINITI model. Getting the right part requires knowing your engine:
- Q50 2.0T (2016–2020): 2.0L turbocharged four-cylinder. Completely separate parts catalog from all V6 variants. Catalytic converters, intake components, sensors, and exhaust parts are unique to the 2.0T.
- Q50 3.7L V6 (2014–2015 only): Naturally aspirated VQ37VHR. The original Q50 engine, replaced by the 3.0T after two model years. Parts for the 3.7L Q50 are specific to this engine.
- Q50 3.0T 300HP (2016–present): Twin-turbo VR30DDTT V6. Most common Q50 powertrain. All exhaust, sensor, and turbocharger components are VR30DDTT-specific.
- Q50 3.0T Red Sport 400 (2016–present): Higher output VR30DDTT with different turbocharger calibration. Upgraded brakes, sport suspension, and some unique engine components distinguish this variant.
- Q50 Hybrid (2014–2018): 3.5L V6 with electric motor assist. High-voltage hybrid drivetrain components are unique to this variant and require specialized handling.
Direct Adaptive Steering — The World's First Steer-by-Wire Production System
The Q50 introduced Direct Adaptive Steering as the first production steer-by-wire system in automotive history. There is no mechanical connection between the steering wheel and the front wheels — the system uses electronic actuators, sensors, and control modules to translate steering input to road wheel movement. This technology requires genuine OEM parts throughout:
- Steering column assembly — OEM only, third-party not compatible
- Steering angle sensor — safety-critical, calibration-specific
- Road wheel actuator — INFINITI-exclusive component
- DAS control modules — pre-programmed to INFINITI specifications
Any Q50 displaying steering system warning messages must be repaired with genuine OEM parts from an authorized INFINITI dealer.
Top Q50 OEM Parts
- Catalytic converters — Engine-variant specific. Confirm 2.0T, 3.0T 300HP, 3.0T 400HP, or 3.7L before ordering.
- Engine Control Module — Must be genuine OEM. DAS-equipped models require dealer programming.
- Air mass sensors — Engine-specific calibration. VR30DDTT and VQ37VHR use different sensors.
- Suspension components — Sport trim uses different struts and shocks from base.
- Brake components — Red Sport 400 uses upgraded brakes with unique part numbers.
- Turbocharger components — Wastegate actuators, intercooler pipes, boost sensors for 3.0T variants.
Frequently Asked Questions
What catalytic converter fits a 2019 INFINITI Q50 3.0T?
The 2019 INFINITI Q50 3.0T uses specific catalytic converter assemblies for the VR30DDTT twin-turbocharged engine. The exact OEM part number depends on whether your vehicle is the 300HP base or 400HP Red Sport variant — the exhaust system calibration differs between them. Enter your full 17-digit VIN in our parts search for confirmed fitment, or contact our parts department with your engine code and we will identify the correct OEM part number.
What is the difference between the Q50 3.0T 300HP and Red Sport 400?
Both use the VR30DDTT twin-turbocharged V6 but with different boost calibration producing 300HP and 400HP respectively. Most engine components are shared but some turbocharger, exhaust, and calibration components differ between the two outputs. The Red Sport 400 also features upgraded Brembo brakes, sport-tuned suspension, and performance-tuned DAS steering response not found on the 300HP variant. Always confirm your specific output variant when ordering engine, brake, or suspension components.
Are Q50 parts expensive to maintain?
Q50 maintenance costs are comparable to other luxury performance sedans in its class. Routine items like filters, spark plugs, and brake components are available as genuine OEM parts at competitive dealer-direct pricing from INFINITI of Akron. Higher-cost items like catalytic converters and turbocharger components reflect the twin-turbo engineering. Purchasing directly from a certified online dealer provides OEM quality at competitive pricing with nationwide shipping — often significantly less than a local dealer service department markup.
