AMG Driving Day at Brooklands

[2 5HAN]

Went up to Brooklands today with my sister and a friend and had an absolutely excellent day.

Everything from the staff at the door welcoming us, to power sliding the SL63 round the wet track, to going down a 1:1 gradient in an ML320 upto and including oggling every AMG model available for sale.

Cant believe we all forgot camera's "IDIOTS" i know.

Anyway i can highly reccomend it to anyone that want to see what these cars really are capable of in a safe and controlled environment with the benefit of someone talking you through all your mistakes haha

On a positive note i think my sister got so much more from it as she was able to spend 2 hours in an SLK55 and really explore its limits. (Her normal day car)

Also as a side note i cannot believe how well the ML did on their off road track. So much for the Chelsea Tractor Tag.

I am going to be calling the Range Rover dealer i bought the TDV8 from to see what they offer for customers.

And no of course i didnt drive over 70 mph on the way home.

You just drove sideways the whole way home.

It is a good venue.

What does it cost or is it a invitation deal?

Whats a 1:1 gradient hill, that is either a flat road or a vertical one?

Im amazed you all forgot the camera too

Isn't that a 45 degree incline?

No a 1:2 hill is a 50% incline, that would be 45 degree.

1:1 is vertical.

I'm hanging on to my disagreement here.

1:1 says you climb 1 unit of height and move forward 1 unit of length. The units are the same, so 45 degrees.

Vertical would be 1:0.

In mathematics, a small incline upwards will have slope 0·1 (i.e.10% or 1/10 or a rise of 1 in 10)
a road going slightly downhill had slope -0·2 (i.e. 20% or 1/5 or a fall of 1 in 5); a fairly steep road uphill will have slope 0·4 (ie 40% or 2/5) and the same road travelled in the other direction (downhill) has the same number, but negative: -0·4
In mathematics, a "1 in 1 " slope will means a metre rise for every metre travelled "along", so the slope is 1:1 = 1/1 = 1 or 45 degrees (upward).

Note that with the other interpretation (using the sine of the angle) of 1 in 1 is a rise of 1 metre for every metre along the road. This would mean a vertical road (a cliff-face) which is not at all the same thing as a tangent of 1!

This is what i meant and yes 45 degrees would be about right not that i could really see as i was facing the sky one minute and the floor the next

As for cost mine was a Invitation from my dealer and very nice too but you can buy the days via their website.
Costs vary depending on what you want from the day.

Worth every penny in my opinion.

Sorry to keep going on, check the highway code, it states that a 1:5 hill = 20% gradient, therefore from my reckoning a 1:2 hill is a 50% gradient = 45 degrees.

I'm still hanging on here, and Johnny above backed my point mathematically.

Draw it. I just did to prove it to myself!

But, I'll admit I'm confusing myself now. If you draw a 1:1, i.e. up one along one then you've risen at an angle of 45 degrees (I know disagreement on this one is the point but bear with me).

However, if I draw a 1:5 the angle is about 10 degrees. Now I accept that a 1:5 is thought of as 20%, but 20% of what? If you took 0% to mean horizontal, and 100% to mean vertical then 10 degrees is not 20% of that range

This thread really is going off at a tangent

Shirley, you drive under the auspices of the Highway Code, if driving in the UK, not some mathematical equation, like i said check the HC.

How can you drive 1 metre up and 1 metre along, impossible, remember the hypotenuse, you cant do it. 1:1 is either straight up or flat on the ground, even with my very basic trig experience i can work that out.
