抓地最好的seden是什么车
Most 抓地最好的车 is usually not sedan, but a few are very good, most
recently one is panamera. STI and EVO are also sedan with very good 抓地.
雨雪天不要滑
That is actually depending on your tire, wheel set up.
雨 is also different from 雪, 雪 is different from Deep 雪, which is also
different from ice.
You need the correct kind of gear for each situation.
In deep snow you will never 滑, but you are also stuck, not able to move
without the right kind of equipment.
If you live in area with some snow and ice all winter, it is best to get a
real 4x4 (truck based body on frame) vehicle with mattracks. (design is
based on a 11 year old kid's drawing in MN)

4WD 和 AWD 有什么区别吗
This could take long time to explain to you, but here is a short version.
The term four-wheel drive typically describes larger passenger vehicles that
may allow the driver to manually switch (sometimes with an automatic option
) between two-wheel drive mode (if available) for streets and four-wheel
drive mode for low-traction conditions such as ice, mud, snow, or loose
gravel.
All-wheel drive (AWD) is often used to describe a "full time" 4WD that may
be used on dry pavement without damaging the differentials, although the
term may be abused when marketing a vehicle as there are no specific
definitions or guidelines (per the SAE for example) to differentiate these
terms. AWD can be used on dry pavement because it employs a center
differential, which allows each axle to rotate at a different speed. This
eliminates driveline binding, wheel hop, and other driveline issues
associated with the use of 4WD on dry pavement.
Because all 4 tires in a full time AWD system are connected by a system of
differentials, they are potentially very susceptible to torque reduction
when a wheel loses traction. Without sophisticated traction control systems,
they would become immobilized when any one of the four tires lost traction.
A traditional part time 4WD system does not connect the front and rear via
a differential, and therefore does not suffer any front/rear torque
reduction—if a front tire loses traction, it does not reduce torque
delivered to the rear tires, even without traction control systems.
Part-time 4WD systems are mechanically simpler and cheaper than AWD systems.
Also, a part-time 4WD transfer case is usually equipped with a reduction
gear setting that provides for higher torque at lower speeds, a vital
feature for vehicles that will see much off-road use. In AWD systems a more
expensive separate reduction gearbox is usually used. The main drawback of
4WD is that because it lacks a center differential, a part-time 4WD system
can only be used in low traction situations where the wheels have the
ability to slip as needed.
For these reasons, full-time AWD is appropriate for improving on-road
handling and is seen on cars and car-based crossover SUVs, while traditional
part-time 4WD systems without center differentials, or with locking center
differentials, are better for heavy-duty use such as off-road or in deep
snow and are commonly seen on trucks and truck-based SUVs.
