The G37 uses a traditional hydraulic power-assisted rack-and-pinion steering system. It relies on a belt-driven hydraulic pump to supply assist, and its feel is tuned to provide ease of steering at low speeds with steadier feedback at higher speeds.
How the G37 steering works
The Infiniti G37 employs a conventional hydraulic power-assisted rack-and-pinion setup. When you turn the steering wheel, a belt-driven pump pressurizes hydraulic fluid that helps move the steering rack. The system is typically designed to be speed-sensitive, offering more assist at parking speeds for easy maneuvering and reducing assist at highway speeds to preserve a connected road feel. This generation of the G37 does not use electric power steering (EPS) as its primary mechanism.
Key characteristics
Below are the core attributes that define how the G37 steers and how it feels behind the wheel.
- Rack-and-pinion steering with hydraulic power assist
- Belts-driven power steering pump circulating hydraulic fluid
- Speed-sensing (variable assist) to adjust effort with vehicle speed
- Hydraulic reservoir, hoses, and a pressure relief valve integrated with the steering rack
- Typically no electric power steering in this generation
In summary, the G37’s steering is a conventional hydraulic setup that emphasizes precise feedback and predictable response, with variable assist rather than an electric steering boost.
Maintenance and troubleshooting
Regular maintenance helps keep the steering responsive and safe. Key tasks include checking the power steering fluid level, inspecting for leaks, and ensuring the drive belt and pump are in good condition. If steering feels loose, inconsistent, or noisy, it may indicate worn components such as the steering rack, tie rods, or internal pump wear, and a professional inspection is advised.
Summary
Answer in brief: The Infiniti G37 uses a hydraulic power-assisted rack-and-pinion steering system, not modern electric steering. It employs a belt-driven pump, variable assist with speed, and traditional hydraulic components to deliver steering feel and ease of use. Across its range, this setup aims for a balance of low-speed maneuverability and highway stability.
