EV6 - will make it back up the slope?

Can a Kia EV6 Tackle an 18% incline?

After a lengthy ten-hour drive, we've made it to our destination in Ilfracombe. We parked our Kia EV6 in the spot designated by our host, which seemed perfectly fine at the time. However, this morning the slope appears significantly steeper than we initially thought.

We've used an app to measure the incline, and it's indicating an 18% grade. What's more, there's no run-up space for momentum. I know the Kia EV6 is a powerful machine, but I'm curious if any of you have encountered a similar scenario. Do you think our electric vehicle will be able to handle this steep incline?

Votes please. Not panicking as we have AA, but not going to try it today. It'll be sometime next week...

We had a same situation with our Kona EV a couple of years ago (South Devon in this case). It managed fine, even with FWD (although it was dry). Difficult to compare gradients from photos, I know, but it looks very similar.
The fact that there are parking places marked out in a UK location suggests that ICE cars with manual gearboxes can cope and I'm sure torque at the drive wheels in your EV6 is greater than the average ICE car in 1st gear. If you made it down the slope, I assume you didn't ground over the lip of the gradient, so no worries there. I would not be concerned tackling that slope in our current RWD EV6. In fact, because you can take it as slowly as you like, I would predict an anxiety-free experience.

That’s steep for sure, and grades like that can be a challenge when pulling heavy things.

I’m pretty sure any vehicle in production today could handle a grade that steep. If you got progressively steeper, there are at least a hundred different models that would lose traction before the EV6 does. Nothing that’s FWD and RWD with a lower proportion of weight on the rear axle wouldn’t do as well as even a RWD EV6.

Bottom line is that the EV6 is one of the most capable vehicles for steep grades.

Low center of gravity will also absolutely make this a cakewalk. You really need to worry around the 45 degree mark, 18 is nothing. Even at 45 degrees, with the low center of gravity our cars have thanks to the battery, I think we'd do better than ICE cars, as they are front loaded with weight, and depending on traction. With RWD, up or down, I don't see an issue, with AWD, even easier.

Yup, there are a few streets there with grades of 31% or more, with the steepest coming in at 41%.

Side note--back in the day I learned how to master using a clutch by practicing on some of the very hilly streets in SF. Imagine being at a stop light facing uphill on one of those steep streets, with another vehicle right behind you, then once the light turns green you're hoping you can engage the clutch quickly enough before your vehicle rolls backwards and hits the guy behind you.

Are you asking because you're towing? That's the only reason I'd think twice about it.

It’s very difficult to accurately portray a steep grade with a photo, but I believe that it’s incredibly steep.

If anything short of a four-wheel-drive in low range can make it up that hill, your EV6 will. It’s tough to tell with traction control, but I believe they have the torque to spin the wheels on dry pavement. Either the wheels will spin or you’ll climb the grade.

"Excuse me host, has any car EVER not managed to get up that short incline that is paved in such a way that it clearly looks like it is designed for cars, as I am wondering if my electric can that produces fantastic torque across it's entire power range might require the AA to help me", would appear to be an eminently more correct place to ask this question rather than a forum of people who have never seen the hill and are trying to judge from pictures.

This thread has all the traits of click bait which the OP has some history of, such as showing his AWD indicating a top-speed of 163MPH, which was deemed to be photoshopped.

Subject: Re: Misunderstanding and Clarification on Measurements

Hey there @tangey,

I can see that a post last year has caused some confusion. I must clarify that the data I shared was due to an unintentional glitch on the app. The numbers displayed were actually in km/h, not miles. I can understand how this might have caused some misinterpretation. Here's a more recent snapshot for your reference. I genuinely appreciate your engagement and passion for these discussions. Let's continue to keep this forum a place of shared knowledge, respect, and friendly banter 👍

We had a problem with our previous EV when trying to climb a kerb from a standstill. It limits the power/torque at a standstill so it doesn't fry the engine with too high a current, which meant it wouldn't climb a kerb if you were parked against it. With a very short run-up, it would climb up fine. This was a 2015 Outlander PHEV, with an electric motor on each axle (and no connection to the wheels for the ICE at low speeds)

We've taken the EV6 up a 25% slope in Cornwall without a problem

I reckon the root of my concern lies in a past experience. Last year, we found ourselves in a tight spot in Keswick, having pulled off the A66 to stop at a pub named the White Horse. As new EV6 owners, we were cautious and chose not to navigate past some parked cars that led to the car park, as the gap appeared too narrow. So, we decided to reverse back and intended to use a private driveway to perform a three-point turn and then back out the way we came. However, the EV6 was unable to reverse up the steep incline of the driveway. As you suggested, that this might have been due to the wheels being up against it.

Considering our upcoming hill challenge, this memory is definitely causing some anxiety. However, I'm thinking of giving the hill a try tomorrow...

I never pulled my incline meter out but….We drive in and out of our ranch community , climbing from ~ 3300’ to 4200’ on a primitive road maybe 1/8 long with not issues and we have a RWD KIA EV 6 Gt Line. She crawls right up. We always drive in ECO ( personal range choice). Never have a reason to “ gun it” It was a concern before we purchased but never and issue. We have been on the same roads when wet too but never in a heavy monsoon downpour here. But I just don’t dive our vehicles purposely it that muddy mess😉
I never had reason to stop park and go on the incline

I do use the Auto Hold setting!
On a different note…… BTW never leave that Auto Hold ON when trying to be rolled through a car wash ( In Neutral) as it may not track through. Lesson Learned! 😳
So I go through.. Power ON, park OFF, Auto Hold OFF.
And just press on Auto Hold when I am out . As you know…You don’t need to use Auto Hold

The roads going up Mt. Washington in Pittsburgh PA are very steep. My last car with a 2.2 liter ICE and a 6-speed paddle shifter worked hard to climb those hills, and it was hard on my brakes going back down. By contrast, it was a cakewalk for my EV6 in iPedal mode: Going up, I could accelerate any time I wanted to; going down, I never touched my brake pedal-except when sitting at a stop sign.🛑
