Custom Drive Mode - Pedal Force What's the difference?

[Ethernea]

Hey guys - quick one...

In custom drive mode, we have 3 options:

1) Horse Power - eco + normal + sport
2) Steering - light + normal + heavy
3) Pedal Force - comfort + normal + sport

And I have 2 questions from this...

1) what's the difference between comfort, normal and sport for Pedal Force?

I've tested them... But I don't feel any difference.

Am I missing something?

2) Horse Power - Sport is what I use because I've noticed that if I use ECO and I need to quickly pass another car on my front... It doesn't speed up quickly even if I step hard on the gas pedal.

But if I use sport... Oh my cat - this car warps!

My question is... Related to that icon near regenerative level - where it says X number % Power

I've noticed if I step on the gas lightly it stays between 1 to 10% power and pushes forward comfortably most of the times.

If I stay in that range - doesn’t it count as ECO mode to save mileage?

I know the range "kms left" drops 20 km from eco to normal, and another 20 km from normal to sport - just by switching driving mode, not actual moving the car. So these I guess are estimates.

But if I don't speed up all the time and drive slowly... It has to save mileage right? Even if it's set on sport?

I'm wondering if this "number % power" metric is really like the maximum WATTS the battery is using to push the electric motor harder to spin the wheels.

The harder it pushes, the more energy it consumes.

Maybe having sport enables the top limit to be used (but I've never seen it over 60% by the way, maybe I can step the pedal deeper but hasn't been needed so far)

Any insights on this?

The manual is very vague... And I can't find videos on this.

And that's it lol

What is this "gas" of which you speak? ?

 

[Alb]

It's what Americans call a liquid

"Step on gas" is a term to refer to push down the pedal to accelerate.

Don't know how it's called in EV - just speed pedal?

 

[siteguru]

An EV has 2 pedals ... the Go pedal and the Stop pedal. And some EVs even integrate the Stop into the Go pedal. (Otherwise known as One Pedal Driving).

It's short for gasoline, an alternative name for petrol. Petrol was once a British brand name but had become appropriated for common use.

Accelerator.

ok ok enough about pedal names haha can actually someone reply to my original questions on my post? :\

 

[InnocentSmith]

Don't see any difference either but... does your car actually remember the Custom settings after you turn it off? Mine doesn't, is it expected to remember the custom drive mode settings?

 

[wattmatters]

can actually someone reply to my original questions

I suspect for some changes to pedal force setting alone may not be noticeable, while others will be able to tell. Certainly in many ICE cars there are computer chip interfaces which can affect the throttle responsiveness of the pedal.

I'll have to try it out and see if it's something I can distinguish. Proper testing however needs to be blinded, e.g. have a passenger make the changes to the setting without the driver knowing what change was (or was not) made and for the driver to report what they notice, if anything. Repeated many times for statistical significance.

The settings affect the systems as follows:

• Horse Power is about acceleration, how hard you have to press to get the car to respond, as you have found out Sport makes the car feel very lively and sharp, but it doesn't actually make it faster I don't believe. It is about how much you press the pedal to get a given effect.
• Pedal Force is about the brakes, how hard you have to press to get a particular effect. It doesn't affect the maximum braking available but you should find the brakes are 'sharp' in Sport mode and 'mushy' in Eco.
• Steering just changes the weight of the steering, how much effort it is to turn the wheel, it doesn't affect how many turns or how far you turn it to get the wheels to move a given amount.

You are right that if you drive gently in Sport mode it won't be any different to Eco, it is just that it is harder to drive gently in Sport. A specific % power is the same in all modes and yes it does directly relate to the Watts used by the motor, although the conversion factor isn't published.

Yes. It does. With horse power and steering.

Pedal force doesnt save.

It doesnt save any for you? Hmm whats the use of custom then...

Good info. Thanks for that.

So Pedal Force is brake pedal?

I thought horse power is force sensitivity delivered to wheels

And steering is the sensitivity for turning wheel...

So i imagined pedal force was something related to the pedal - how hard or soft it is to push down and speed up...

But it makes more sense to be brakes.

So...

1) steering option is steering wheel.

2} Horse power is accelerate pedal.

3) And pedal force is brake pedal.

I'll test braking with different pedal force options and see if i feel anything. If its brakes & it always return to normal - makes sense because of "security" stuff.

Does anyone know if there is BHP difference between Normal &’Sport modes? Eg you need Sport for max power and perhaps normal is 10% less.

Aye my Granddaughter and I used best part of $200 dollars worth driving around San Diego and Los Angles visiting the zoo seven times and the La Brea museum etc. Then my son and I used a lake of diesel towing two Harley Davidsons from San Diego to Sturgis, South Dakota a couple of weeks ago. 3300 miles round trip at about 13 mpg.

 

[Ethernea]

Notice.

Pedal Force is brake power.

In comfort you need to push harder to brake faster (and stronger).

Sport mode light press the brake pedal makes car stop much faster.

Normal is in the middle and i prefer it to be that way.

Comfort feels like its not braking (though mine is still under this period of bedding pads and rotors < 1500km)

 

[wattmatters]

Regen setting would kinda mask brake pedal force.

 

[wattmatters]

I tried the pedal force settings today. There is a very noticeable difference between Comfort and Sport. In sport the braking response is far sharper / more aggressive. In comfort it's like a way to ensure no sudden (negative) acceleration. More brake pedal travel required to engage the brake strongly.

By the way, the MG4 user manual refers to the accelerator pedal.

Stop go pedal as in dodgem car

 

[Rolfe]

I know what it means. It's just never been normal usage in Britain and it seems particularly perverse to adopt it for an EV which isn't using gas of any description.

Best thing is no black brake dust on driveway this tells me that the brakes are hardly being used lovely probably never change the pads.
Years ago I drove a Leyland tiger bus with a retarder that also felt weird stopping without pushing hard on a pedal.

Braking with Regenerative makes common brake pads... Last longer...

I didnt think about that.

Is there a clear video that shows the mechanics of EV's regenerative brakes?
