Last you week you may recall I shared efficiency stats on driving through the high mountains of Colorado, but after driving over Vail Pall and through the Eisenhower tunnel the drive was all down hill for 60 miles. Yesterday, I decided to drive from Denver to Salt Lake City and get a better understanding of how the efficiency is impacted by going mainly up hill for the first 160 miles of the drive. The first part of the drive yesterday covered the 160 miles from Denver to the Electrify America charger in Glenwood Springs, CO. The first 100 miles are marked by two high mountain passes - Eisenhower tunnel at 11,000ft and Vail Pass at 10,600ft. I will share a few pictures that show the start of the drive, the battery state at the top of Eisenhower tunnel, the affect of regen/recoup after coming down from Eisenhower tunnel, the state of battery at the base of Vail pass, the state of battery at the top of Vail Pass, the state of the battery at the bottom of Vail Pass showing the affect of regen/recoup, and then finally the over all efficiency and battery state when I arrived at Glenwood Springs after 160 miles. I realize that few of you live in high mountains, but I am impressed with my 4s' efficiency. I have 20's on the car, and the weather was between 50 degrees and 75 degrees during the drive.

Here is the impact to the climb up to the top of Vail pass - going east to west is short and steep so impact was not to major:

And, finally, the over all efficient results when I arrived into Glenwood Springs, CO:

There was a lot of traffic and and construction, so it kept my overall speed down, which helped with the efficiency. Overall, I am impressed with how the car handles in the high mountains, and the overall battery efficiency for driving long distance. I made two 20 minutes charging stops at Electrify America locations yesterday and was able to cover the 550 miles from Denver to Salt Lake City.

I realize many of you do not live in high mountains like we have in Colorado, but I wanted to share efficiency stats for you that live in more mountainous locations. Don't be afraid to take the car out and lay down some miles because the vehicle is very efficient.

Thanks for the post. I will be doing almost that exact drive tomorrow and was curious how the Taycan was going to do.

Thanks for the post!

Are those numbers in the pic I kept the summary of the drive without charging?

Is that drive pretty much up and down or was it also curvy and fun to drive? How was the drive itself?

thanks again

@Reg : I made the drive from Denver to Glenwood Springs yesterday in one shot - it is only 160 miles, so very easy to do. the challenge is the construction through Glenwood Canyon right now which reduces you to stop and go traffic for 10 miles. In regards to the drive, it is not super curvy or that fun because it is driving on an interstate through the mountains. I have had the car for a month now and have driven to Aspen, via Independence Pass, and that was on small, curvy roads and super fun. Driving to Salt Lake from Denver on I-70 is not that fun. For me it was an experiment in understand the efficiency of my 4s in the mountains since it is what I have to do if I drive west of Denver. What I found out is that the car is more efficient than what is forecast on A Better Route Planner - for instance, I was able to skip Grand Junction yesterday to charge. Going 550 miles and only stopping to charge twice for 20 minutes is not bad considering you are in a Taycan.

Thanks. That is crazy good.
I am picking up mine in a month and have a 400 mile trip back (although flat land) so looking forward to that.

Great data and pictures, thanks! I include a picture of my range meter from today.

Since one week, I have a charger port in the garage, the car is now running completely on solar.

@thecoloradokid thanks for a great example of real life driving. Impressive range and consumption. Great to hear somebody reporting some hilly driving. Love it!

Plus, some roads in Colorado are so high that ICE have problems with the thinner air... EVs don't.

So @thecoloradokid if you play with ABRP, I was wondering if you can try 300Wh/mi as the 65mph est. That's what I think will match the car.

I did a good chunk of this drive myself today and was really impressed with the range I got out of my 4S. I left the house at 100% and supposedly 215 miles of charge. I drove 225 miles and had 30% left when I got back. I did not charge on my trip (see below). That implies a range of 321 miles!

I would have had even better range, but coming up Vail Pass I was passing slow moving trucks behind a Corvette ZR1. As far as I could tell, he was accelerating at full throttle and I was keeping pace. We were at about 10,000 feet above sea level.

The ZR1 driver was surprised enough that he was giving me all kinds of thumbs up signals when I had to split off from him. I don't think he expected anyone to hang with him.

The one downside was that the Electrify America station on my route said it was available but it failed to charge my car and customer support couldn't help. I am glad the Taycan has exceeded expectations on range, but Electrify America needs to get the Frisco station working reliably or travel to and from the mountains is going to be tricky for Denver people.

@kmcdonal : you are exactly right. the Frisco EA location is a disaster, and has been for over a month. This is why it was so important for me to figure out the efficiency impact in driving from Denver to Glenwood Springs because I do not want to depend on the Frisco EA location. The good thing is that there are also 50kw Chargepoint chargers in Eagle, Carbondale, and Basalt, but I have not used them yet. .
