Be careful not to downshift into wrong gear. My Audi mechanic friend was rebuilding a transmission from a wrong downshift, rev limiter only works on the throttle rpms.

I love a good downhill (rolls down all windows) when I'm sweating in my car. I've even stuck my arm/hand out to slow down an extra mph when needed! Brakes are for emergency use only!

For those who said "why not neutral" because keeping your car in gear is infinity MPG and coasting in neutral at hwy speeds is "only" 200-400 mpg. That and most hills in my parts would put me to 100+mph in neutral.

If you have not done this before, try downshifting one gear at a time, until the tachometer gets too close to the redline. If you don't have a tach, then go by ear, I guess?
Sincerely, Neil

Can you post a video of a trip down and up this hill? I would love to see it.

You yanks really don't do manuals do you lol

The revs will be the same going downhill, on the flat or uphill in each gear. So if you want to know what revs are safe at each speed try accelerating in each gear first to see what speed each gear achieves to the rev limiter.

Above that speed for each gear you can/will grenade your engine in one quick lift of the clutch. If that sounds far too complicated, don't argue just stick to autos.
