Watch Tesla Model 3 Regen & Accel Tests On Steep Hills In San Fran

Turn on Subtitles for details about the streets and some commentary!

One pedal driving on San Francisco’s steepest hills?

Tesla Explained shared results of an interesting test of a Tesla Model 3 (the rear-wheel drive, long-range version). The test was on San Francisco’s steepest hills.

The idea was to see whether regenerative braking will be strong enough going downhill to not use brakes. And, on the flip side, to find out whether acceleration is still brisk going uphill.

As you can see, the steepest being Filbert Street at 31.5 degrees slope, Model 3 speed up from 4 to 21 mph using only regenerative braking.

On the less steep slopes, top speed was 15 mph using regen only and then 14 mph at 20 degrees slope.

In the case of uphill acceleration on Jones Street (30 degrees slope), Model 3 speed up from 0 to 35 mph.

Electric vehicles seem to be a perfect fit for such hilly city. It’s expected that the dual motor all-wheel drive Tesla Model 3 will be an even better choice. That’s mainly due to its stronger regen.

Wonder if this would have been better if we could see what their foot is doing on the accelerator and brake peddles. Or maybe some commentary.

True, but the average Tesla YouTuber would just post 0-60 at 30% downhill and be done with it. „Look sub 4s on a mid range 3!“ While almost killing a group of elementary schoolers…

So this is at least informative!

This test was done on the rear-wheel drive, long-range version it would be very interesting to see the other versions.
This test would be good on the world’s steepest street which is in Dunedin, New Zealand.

It is also a lot of fun to go down really long, really steep hills that can recharge your battery enough so you have a higher SOC at the bottom than you had at the top. Have done this a few times in western NC with my Zero SR and Energica Eva.

It is not degrees, it is 31% slope which is about 17degrees. Driving on a 31 degree slope is impossible.

Thanks for explaining that! I learned something today. From the article linked below, I see a 100% slope corresponds to a 45° angle.

Too bad the article probably won’t be corrected.

I wish they would fix the article but I guess not. It is a pretty blatant mistake. The standard staircase is about 32 degrees. It is like a steep ski slope, a double black diamond perhaps, if you are familiar with skiing. I doubt any non-tracked vehicle can even park on a grade that steep, the wheels would start slipping.

Not very interesting without comparisons.

But we dare not bring another brand into the equation as NOTHING compares to a Tesla ź which is why so many Tesla articles by fan mags are such fluff.

It’s certainly noticeable that no brand other than Tesla attracts persistent serial bashers posting pravduh and FÜD about the company… such as your posts.

Is it that you’re afraid Tesla’s growing success will drive your company out of business, or are you one of the few remaining diehard TSLA short-sellers; the ones who foolishly refuse to exit their position no matter how much money they lose?

I put the snide comment in just to prod you to show us your uninformed rants and lyrical writing. Fanboys can’t be tamed! 😉

saw the autonomous chevy bolt

Where?

Yep. The subtitles call it a Waymo, but it’s a GM/Cruise Bolt. Notice how uncertain it was on the left turn.

there was a pedestrian and an oncoming car. I think the Bolt was waiting for them both to make correct moves (the person doesn’t turn around and the oncoming car to slow down to a speed of a car coming to a stop at the sign) before making the turn.

Looks like my Bolt EV. Spooky!

Not many are on steep hills a lot. It’s not really a big issue but it is interesting.
I’d like to travel from the Grand Canyon down to Phoenix with only 1/2 a charge and get to Phoenix with a full charge in our Tesla model 3.

I was in SF in July and still remember those hills. And I see the Coit Tower I climbed!
Even when you step on the brake pedal going down a steep hill, the car will first further tap into the regen braking before relying on the disc brakes… at least that’s what my LEAF does.

Tesla is different than Leaf – brake pedal is 100% friction braking.

This guy failed to read the (very clear) instructions that the DMV includes with HOV stickers (complete with placement diagrams) and managed to place the wrong size HOV sticker on his front bumper (and presumably elsewhere too).

The red HOV sticker set includes two large stickers and two small — the small ones go on the front and rear bumpers, while the large ones go on the rear fenders. The main photo (of the blue Model 3) clearly shows one of the large HOV stickers incorrectly slapped on the front bumper. Looks terrible, and lets everyone know, “I dropped $50K on a car, but can’t read instructions”.

Hi All, this is my Video! 🙂

I want to thank you all for your feedback. I‘m getting in to the whole YouTube thing and slowly trying to make the videos better and more informative.

Would super appreciate a „sub“ on the channel.

Oh yeah, I posted a video of Model 3 using Autopilot on the Golden Gate Bridge too. Here it is: https://youtu.be/W-BokuJTXvo

Just curious here. Is the regen system connected to the ABS system on most four wheeled EVs? On my Energica Eva if the regen is strong enough that the rear wheel could start to slide in slippery conditions the ABS system will back off the amount of regen allowed.

Hmmm what powerdrain did it take to get to the top of the hill and how much Regen did it get back at the various Regen settings available in the model 3
What Regen would you get back if you could program the car to hold the speed at say 15 miles an hour all the way to the bottom of the hill. Would you get more bck than what you used to get to the top of the hill??
Much like the other guy who was towed 1mile and got back in excess of ten miles , that would be an interesting question.

I’ve never seen regen recoup more than used energy. On my I3 I get perhaps 15% back of used energy consumption when regen is done properly. So you won’t see much higher numbers there in terms of energy recoup on steep hills. You’d need a lot of downhill to make that sort of energy go back in again. And then you often times you have to go back the same way you went, so there’s that. (Numbers are written while being in bed super tired, so don’t slaughter me if I’m dead wrong)

You can’t get more energy back from descending a hill than you used to climb it, because physics.

My Bolt will regen to a stop on that hill without the paddle. Love the strong regen in L.
