What is the difference between two and a half turns and one and a half turns of the steering wheel?

Here are the specific differences between two and a half turns and one and a half turns of the steering wheel:1. Transmission aspect: The number of turns the steering wheel can make is determined by the transmission ratio of the steering system. The larger the transmission ratio, the more turns the steering wheel can make, making steering lighter, but the car's handling becomes less sensitive; the smaller the transmission ratio, the fewer turns the steering wheel can make, making steering heavier, but the direction is very sensitive, with the car turning sharply even with a small angle of the steering wheel. 2. Gravity aspect: A steering wheel that can make two turns is lighter than one that can make one and a half turns, but the handling sensitivity is not as good as that of a car with one and a half turns. Cars that focus on comfort have steering wheels with more turns, while those that focus on handling have steering wheels with fewer turns.
After driving for so many years, I feel the main difference between two and a half turns and one and a half turns of the steering wheel lies in the handling experience. Cars with two and a half turns have a gentler steering response—it takes more turns to go from center to full lock, so the body moves more slowly during turns. This makes them more stable for long-distance or high-speed driving, preventing the car from feeling twitchy, especially in SUVs or regular family cars, which often feature this design. On the other hand, cars with one and a half turns are completely different—they have a much quicker steering response. A slight turn of the wheel makes the car aggressively change direction, delivering an exciting drive, much like sports cars, making them ideal for twisty roads. However, beginners might find it unsettling. For daily driving, I prefer two and a half turns because it’s more relaxed and less tiring on the hands, especially with power steering assistance. Overall, it depends on the car type and road conditions: two and a half turns are better for regular city driving, while one and a half turns are more thrilling for track driving.
As a car enthusiast, I think the steering wheel rotation has a huge impact. A car with 2.5 turns feels more sluggish, requiring more turns for sharp corners, making it suitable for off-road or family cars, providing stability and reducing accidents, especially when fully loaded—it feels reassuring. However, a 1.5-turn steering is lightning-fast; the car responds immediately to steering input, making cornering exhilarating and perfect for track driving, though it can be tiring over long drives with more direct feedback. I've tried different models—sports cars often have 1.5 turns, while regular sedans usually have 2.5 turns—designed to match the vehicle's purpose. The steering gear ratio is key: 1.5 turns mean a lower ratio for quicker response but higher risk of skidding, while 2.5 turns offer a higher ratio for greater safety. In short, choose the former for performance and the latter for practicality.
When driving, I noticed a difference in steering wheel turns. Regular cars with two and a half turns require multiple steering wheel rotations for turns, making the ride smooth and the body stable, which is very suitable for beginners or daily commuting. Cars with one and a half turns respond instantly, change direction quickly, and have strong high-speed cornering control, but require more hand strength, commonly seen in sporty cars. Overall, different design philosophies affect driving habits, with comfort being the key point.
