Watch part 2 in full-screen...but not right after a meal!

Can my 3.6 L engine make it up there in 'auto' mode?

Re: Need Advice on Mountain Road Driving

Wow it is narrower than I imagined. I see that the thing I guessed as a lift is a tram.

It will easily make to the top in auto mode. But since the road is narrow and sharp turns you may want to keep a little more control on it using the paddle shifters.

It is not that steep, in europe people drive 1.4L-1.6L 4 cyl to mountains. Those are 90-100hp cars. The key is to keep it in the correct gear. Don`t worry to rev it up little bit 3-4k`s.

Re: Need Advice on Mountain Road Driving

If on asphalt absolutely no need for 4WD Low. Just take thee car out of ECO mode. Why sport? You don't have to be in sport mode to control gears manually.

And you should not be afraid of trigonometry. You have the horizontal distance over which it gains the said elevation. You can calculate the grade but that is the overall angle as if everything would be driven in a straight line. Chances are that the road will snake around and it is not going to be that steep.

At any rate, having just driven 4000 miles in some of our country's most beautiful mountains, I can reassure you that there is nothing that the 3.6 L V6 will not conquer. F course pulling your 30 foot camper behind the Jeep up that road might be tricky in itself and you'll be left wanting for power but if you just have a loaded Jeep, you'll be fine.

Re: Need Advice on Mountain Road Driving

Nice video. 1800+ elevation gain from the starting point. The road looks steep, but nothing your Jeep can't handle especially it is all paved. I have taken my Jeeps on a much steeper dirt road and they did fine. Just make sure no one is coming the opposite direction when you are on that road. LOL.

Here is a time lapse video of me driving down from Mt. Evans few weeks ago. Not scary at all. Watch in HD for better quality.



Cheers,
-A

I feel reassured! Also, I got to thinking that Sport mode is supposed to transfer more of the power to the rear axle to give more of a "rear wheel drive" feeling. I believe Auto mode is a 60/40 split which should be better for traction.

It would be a drag to encounter another vehicle going the other way! My first time up the road with my 2001 V8 GJC Limited, there was no place to park at the top and I had to back down about 100 yards to turn around. Steep drops on both sides of the road...my neck was sore for a week!</snip>

Re: Need Advice on Mountain Road Driving

I can't help but thinking about the guys who cut that road, paved it, and erected that tower.

Here is how they built one of the towers:



I know a lot of the guys in the video. Interesting fact...the first helicopter in the video that carries the concrete is the very same chopper that was used to carry Richard Nixon back and forth to the White House!

Re: Need Advice on Mountain Road Driving

That road is no big deal. I saw only one turn that was extra scary, the rest seemed to have run off. Keep your eyes on the inside line, towards the hillsides, this will avoid any problems you might have with target fixation (if you you fixate on anything at all, you end up hitting the hillside -- no big deal).

Going up hill will not be a problem, but you will want to keep it in a low gear going down hill. You don't need a Jeep for this road, you can use pretty much any car.

It's steep, and there's tight switch backs, but they aren't dramatically worse than what you get on the road up to Mt. Palomar ( http://goo.gl/maps/SOgqR ) (which is a normal "highway") or Mt. Baldy ( http://goo.gl/maps/ibQs5 ) , both here in So. Cal.

It's no "Black Bear Road" ( http://goo.gl/maps/3BFzx ), that's for sure.

My question is, should I use 4-wheel low when going up and down this road or is that bad for the drive train or axles going up a steep, paved road with extremely sharp turns? You can see the top of the road if you cut and paste these coordinates into Google Earth:

39 12 17.62 N 121 49 11.53 W

At one point, the road gains 250' elevation in just over 750' horizontal. With no guard rails and a 1,000'+ fall into the valley, you don't get to make two mistakes on a road like this!

I have the V-6. Did the Mt. Washington Auto Road today, about 6000 ft in 8 miles, with very steep inclines. It never even winced like it was a struggle for it. As much as I dislike the klunkyness of the 8speed tranny, it was a dream out there in this.

Re: Need Advice on Mountain Road Driving

I finally drove the road today and the Jeep performed perfectly! I ran in Auto mode and 1st gear and the RPM's around 3,000 all the way up and down and had no problems. The 3.6 L V6 had plenty of power to make it up the steepest, tightest turns all the way to the top. The drive up was a bit scary, but going down was a piece of cake!

The pictures are taken from about 2,000' above the valley floor on the tram that gets you to the top where the comm site is located. In the close-up, the Rocky Road Outfitters rack is visible.

Glad you made it. I was going to add before you did the drive not to sweat it too much.

There's a drive I love in SW Colorado headed to Moab. Through paradox canyon. At the end there's a switch back about 3 miles long with 180s all the way up. Very steep grade (36% I believe). I made the drive many times in my 98 ford contour. 4cyl, front wheel drive. Granted its a much lighter car. But slow and stead no problem.

Coincidentally my 95 zj (after I got rid of the dirty cont (our) had a little difficulty. Not with the drive but fuel. If I had less than 1/3 tank going up I had to turn around every 15 min to prevent stalling. Figured I was loosing fuel suction.
