Infiniti Q70 2014-present 3.5L V6 Hybrid Engine Specifications

The 3.5L V6 Hybrid Engine is specifically designed for the Infiniti Q70 Hybrid models from 2014 to the present. It is not compatible with non-hybrid versions of the Q70. This engine combines a 3.5-liter V6 gasoline engine with an electric motor, delivering 360 horsepower and 258 lb-ft of torque. It is paired with a 7-speed automatic transmission and is optimized for hybrid performance, ensuring seamless integration with the Q70 Hybrid's electrical and mechanical systems.

The 3.5L V6 Hybrid Engine requires regular maintenance to ensure optimal performance. Key tasks include oil changes every 5,000 miles, air filter replacement every 15,000 miles, and spark plug inspection every 30,000 miles. The hybrid system's battery coolant should be checked every 20,000 miles, and the hybrid battery itself should be inspected annually. Additionally, it’s recommended to follow the manufacturer’s service schedule for transmission fluid, brake fluid, and other components to maintain efficiency and longevity.

Replacing the 3.5L V6 Hybrid Engine is a complex process best performed by certified technicians. First, disconnect the battery and remove the engine cover. Detach electrical connectors, hoses, and mounting bolts. Use an engine hoist to lift the old engine out. Install the new engine by reversing the removal steps, ensuring all connections are secure. Reattach the hybrid system components and recalibrate the ECU. Finally, test the engine for proper operation. Always refer to the service manual for detailed instructions and torque specifications.

If the 3.5L V6 Hybrid Engine is underperforming, check for error codes using an OBD-II scanner. Inspect the hybrid battery’s charge level and coolant system for leaks. Verify the engine oil level and quality, as well as the air filter condition. Examine the spark plugs and ignition system for wear. If the engine fails to start, ensure the 12V battery is charged and the hybrid system is functioning. For persistent issues, consult a certified technician for advanced diagnostics and repairs.

To optimize the 3.5L V6 Hybrid Engine’s performance, maintain regular servicing and use high-quality synthetic oil. Keep the hybrid battery system in good condition by ensuring proper coolant levels and avoiding extreme temperatures. Drive in Eco mode to maximize fuel efficiency, and use Sport mode for enhanced power when needed. Avoid excessive idling and hard acceleration to reduce wear. Additionally, ensure tires are properly inflated and aligned to reduce rolling resistance, further improving overall performance and efficiency.
