It's definitely not 45 degrees. It's estimated to be around 30 degrees, but it's not over 35 degrees. The front driving angle is small and the rear driving angle is large. The reason is that the front drive power steering is responsible, and that universal joint has an angle limit. If it is too large, it will damage the universal joint. This problem does not exist in the rear drive. Moreover, there is another problem that the rear-drive engines are vertical, so that the steering stroke can be longer and larger, and there is enough space after the tires turn. If you have the opportunity to drive a minivan, Reiz, BMW 1 Series, 3 Series and Mercedes-Benz, you will know the benefits of rear drive. Rear drive is not only a representative of high performance, but also a traditional, nostalgic, convenient and flexible feature. Anyway, I won't choose rear drive because of manipulation. The driving experience of the rear drive is not equal to the good performance of the front drive. Even a high-performance front-drive car with excellent handling is different from the worst rear-drive van and pickup truck. The radius of the truck is the smallest. As long as it is rear-wheel drive, even if the control is bad and disgusting, when you speed up the turn, its driving feeling is absolutely impossible for your predecessor. If you kill on the right side, the general precursor is 1 circle and a half, and 1 circle and a half means to make a circle and then hit the impassable position without guiding your hand.
The rear drive is bigger. If it is an unassisted van, you can do two laps+1/4 laps, and the pickup truck is two laps. I found that the high-end rear wheel drive is also 1 lap and a half (mercedes benz c class), but the tire angle is particularly large, that is, the variable steering ratio. The steering wheel of Reiz seems to be 1 half turn+1/8 turn. It's bigger, and so is the crown. How many times the steering wheel turns has nothing to do with the tire angle. The variable steering ratio used by some supercars. It is very convenient to kill 1 lap when turning. Sports cars are all rear-driven, with short wheelbase and extremely small turning radius.
