audi and kaipola ski jump advertisiement - climbing an icy hill

I saw this advertisement from Audi on their second records on driving
up Kaipola ski jump in Finland. It was a rather impressive achievement
and photos. I could not believe that a car can climb a hill with slope
of 80 degrees, even on a regular ground (not icy road). When I dig out
more information about the Audi advertisement, I read more detail
information on how the car actually climbed up the hill.
I would like to find out comments from the readers about driving up an
icy snow hill with very steep slopes. My immediate questions a
- Could you actually climb up a ski jump by the power of your car, from
a stop, without slipping on an 80 degrees icy/snow slope?. In the Audi
advertisement, they were using a winch in which the car could only goes
up. There was a braking mechanism to prevent the car from slipping
backward.
- If the above answer is no, then how many degrees of slope can a
regular or 4WD car climb a slippery/ice hill slope? What about a
regular, dry, soil or rocky slope?
- Is the wonder of such a climb a result of the high power car (big
engine), the all wheel drive system, or the good quality gripping ice
tires, or all of the above?
- On what icy slope is a car can actually stand still on without
sliding down? I thought that a relatively small slope (with no friction
because of ice) that a car can stand up on icy slope more than say 15
to 20 degrees ( 1V to 3H to 1V to 4H). .... or is the figure even
lower, say 10 degrees ... or less?
- How many degrees slope that Land Rover brags about in their
advertisement? Or a Hummer? I think they are on a regular, dry, rocky
or soil ground, not snow or icy surface.
- How good quality ice or snow tires can reduce the slippage when
standing on a slope? Will car using these tires stand up at say 25 or
30 degrees? I don't think there is any car on any tires that can stand
still at a 45 degrees slope (1H:1V) . Correct me if I am wrong.
- If the Audi car shown in the ad does not have a winch, do you think
it can climb that 80 degrees slope ? What happen it it accelerate
first on flat surface until it achieve a very high speed? If it NOT on
ice/snow slope, could a car (like an Audi AWD) climb an 80 degrees
slope in a dry, rocky, rough surface?
- I assume that contributing factors for climbing a adequate engine
power, all wheel drive or 4x4, good gripping tires, weight of the car,
and a good driver. Are there any other governing factors?

Would like to hear some discussion. Thank you!

37.5 degrees actually.

Cant be 80 degrees. That's absurd.

A quick Google found an interesting article:

And the explains the problem:

" is hard to believe that, after quite literally scaling new heights, he
has just parked his Atlas Grey Audi A6 4.2 quattro 47 metres off the
ground at an angle of 37.5 degrees and that is approximately equivalent
to an 80 percent gradient."

80%, not 80 degrees.

I wonder if the AWD was really useful at that angle. RWD
should have been enough.

At this angle, in terrain (no snow or ice) you will need grip.
Without AWD or 4WD you will be left with a spinning (rear) wheel.
Kind regards,

You really should study physics a little...

Thanks for the correction. I checked the ad again, and it was 80%
grade.
37.5 degrees is more likely! It is still very steep, though

Not 20 minutes after my last post, I saw the commercial itself!

In a given distance it rises 80% of that distance.
