Which factor does NOT influence the steering feel of a vehicle?

The steering feel of a vehicle is primarily influenced by factors that relate directly to how the vehicle's suspension and tires interact with the road. Weight distribution affects how load is shared across the vehicle's tires, which can change the responsiveness and feedback through the steering system. Suspension geometry determines the alignment and movement of the wheels, which significantly impacts handling and steering precision.

Tire pressure also plays a crucial role; it affects the contact patch between the tires and the road surface, influencing grip and overall steering responsiveness.

In contrast, engine size does not have a direct impact on the steering feel. While engine size may influence the vehicle's weight and acceleration, it does not specifically alter how the steering system communicates with the driver or how responsive the steering feels during operation. Therefore, engine size is the factor that does not influence the steering feel of a vehicle.
