你有没有研究过F150的四驱?我的只说4hi可以任何速度on the fly切换,但没说干地问题.可能手册上有,我没注意,但是他家网站我没找到tech部份
找到manual了
2H (4X2) - Delivers power to the
rear wheels only. This mode is
appropriate for normal on-road
driving and provides the best fuel
economy and smoothness.
4H (4X4 HIGH) - provides
mechanically locked four-wheel
drive power to the front and rear
wheels. This position is not
recommended for use on dry
pavement. This position is only
intended for off-road or winter conditions, such as deep snow, ice or
shallow sand.
Note: Do not use 4H (4X4 HIGH) on dry, hard surfaced roads. Doing so
can produce excessive noise and increased tire wear. 4H (4X4 HIGH) is
only intended for consistently slippery or loose surfaces.
4L (4X4 LOW) - Provides mechanically locked four-wheel drive when
extra power at reduced speeds is required. This position is not
recommended for use on dry pavement. Use this position for off-road
low-speed operation or when extra power is required, such as climbing
steep grades, going through deep sand or pulling a boat out of the water.
4L (4X4 LOW) will not engage while the vehicle is moving above 3 mph
(5 km/h); this is normal and should be no reason for concern. Refer to
Shifting to/from 4L (4X4 LOW) for proper operation.
Note: Do not use 4L (4X4 LOW) on dry, hard surfaced roads. Doing so
can produce excessive noise and increased tire wear. 4L (4X4 LOW) is
only intended for consistently slippery or loose surfaces.
所以下雪开应该没问题,小雨或者小雪结冰没说...应该还是传统的四驱
