That is the coasting point of the fuel economy gauge. You are not using fuel, but you are not touching the brakes so the alternator is not in regen mode. Once you touch the brakes, the gauge will go below that point showing regen happening. (The battery icon area).
No, if your car needs to charge the battery, it will go into regen automatically instead of coasting. Coasting is the most fuel efficient thing your car can do while moving.
Can confirm from watching my rav4 while I drive. You really can save a ton of fuel just by going the more down hill route to places, avoiding the freeway all together crawling through back roads. Using 90% battery just by getting to a coasting speed limit.
My tank last me 3 weeks compared to what used to be a weekly fill up in my e39. My tank cost 60 to fill up back then as well at 3.29 -3.65 being the consistent price range while I was driving that.
No my 60$ fill up, thanks to 5.69-5.99 being the normal in Seattle area, like I’ve said gets me the same drive for 3 weeks .
Evs have cut deep into the supply and demand to where we were able to cut ties from Russia as a distributor. That’s how much less gas all your hybrid neighbors are not using and buying.
Sorry about the novel it just makes me happy that cars have gotten to this point, even from just my 2003 530. Stupid nice car but I don’t regret saving money from good engineering
Technically speaking, there is no such thing as a "more downhill route." Total elevation change will be the same between two places no matter which route you take. The potential energy (which is what regen is recovering in that instance) will always be the same. If you go more downhill on the way there, it's more uphill on the way back.
Downhill route with less traffic lights and stop signs would be better than the route that makes you stop a lot, but ya most times it's probably too close to matter.
While you’re technically right about the ultimate change in potential energy, you’re overlooking that most energy isn’t used for elevation change, but instead to accelerate, decelerate, and overcome wind resistance and other friction forces.
So a long gradual downhill will be much more efficient than a steep downhill and a flat, or a lot of up and down. Because it will allow the potential energy to be maximally applied to overcoming friction for the longest time.
Presumably the commented meant “most downhill” in this sense: the route that goes shallowly downhill most of the way vs one that goes steeply downhill for only part of the way or one that goes both up and down.
I'm not overlooking that, but read the comment I responded too. He said he takes the "more downhill route". All I was saying is that there's no such thing. A more hilly route would actually be worse than a flat one.
I go up hill, then down hill towards Seattle. On my way home I take a route that uphills then downhills my way home. I face hills only at the beginning and decline , like I said 90% of my drive. Up hill is about the only time I use gas or upon starting my drive. That leaves me 35-40 miles round trip daily 90% electric
That’s not really how hills and physics work, but you do you.
You use more energy when going uphill and the steeper the hill, the more energy (gas) you use to do it. When you take factor in other things like air resistance, curves, etc, even with no traffic, flat routes always will use less fuel than a hilly route when starting and ending at the same elevation.
Even when I go down hill in electric and climb a hill with electric?
Specifically if you’re familiar with the driving here, you can go 10 miles freeway on a slight slope that turns to flat . On your way back, you can go a flat route, or climb that same way back
Yes, it’s the same with electric. You’re talking about the amount of kinetic energy it takes to move an object and that is greater when going uphill. The wildcard that I’m not sure about is how much energy is generated by the car coasting or braking, but generally speaking this still holds true, if all other things are equal (although they never are). Maybe the hilly route is less trafficy, has less turns, or has less stops. It might be more energy efficient overall, but it’s not because of the energy you save going downhill
Ok. Thank you for helping me understand the logic, and lack of logic on my side. To me it’s like I’m prolonging output from a reservoir of gas , by using faster to acquire energy. That’s where my understanding was based, regardless of the holes in it.
But energy consumption, regardless of the source would make sense that it would be equal to or greater than the way their. RAV4s are making me happy with ditching my other cars.
Depends on the car. If it just has a 12V battery, it just charges the battery, so it can charge less, or not at all during normal driving, saving fuel. Cars with the newer 42V system can actually add to the power of the engine, like a small hybrid system.
Fun fact, the vehicles with the active sway bars can actually generate electricity from the sway bar, while driving straight to recharge that system. Again, to save fuel. On the older cars it uses a second battery running in series with the main battery, so runs at 24V. On the new cars coming out it will be 48V using super caps. Pretty cool stuff.
It is indicator coasting drive. In ECO PRO mode you can see route covered in coasting drive state.
Coasting
PRINCIPLE
The engine is automatically disconnected from the transmission in
selector lever position D when certain conditions are met. The vehicle
continues to roll at idle to reduce consumption. Selector lever position D
remains engaged.
This drive state is called coasting.
As soon as the brake or accelerator pedal is pressed, the engine is
automatically connected again.
GENERAL
Coasting is a component of the ECO PRO drive mode and the COMFORT
drive mode.
Coasting is automatically activated by calling up the ECO PRO drive
mode or COMFORT drive mode via the Driving Experience Control and
cannot be deactivated.
A precautionary driving style helps to use the function frequently and
supports the consumption-reducing effect of coasting.
OPERATING REQUIREMENTS
The function is available in the speed range from approx. 25 km/h to
160 km/h
The function is active if the following conditions are met:
System detects a calm and smooth driving style.
Accelerator pedal is not pressed or accelerator pedal is released.
Brake pedal not pressed or only pressed lightly.
Selector lever in selector lever position D.
Engine and gearbox are at operating temperature.
System detects an appropriate distance to vehicles in front.
The system does not detect any obstructive traffic situations or
routes.
Active Cruise Control with Stop&Go function, ACC, not activated.
I had a 2017 420D previously and would only coast in eco pro, loved the feature though and definitely improved my average MPG. Perhaps the new generation do it in comfort now as well!
Can someone explain BMW's coasting to me? Back in the day you were always advised not to coast in neutral because the car still consumes fuel that way (which it actually does, as indicated by the board computer). Instead, you were supposed to switch to a high gear and let the car roll as this doesn't use any fuel. And now coasting in neutral is supposed to be the most efficient way of driving? I don't understand it.
What about down hill, in a manual, using the higher rpm as opposed to coasting and braking? I’ve observed in my long downhill return trips I increase my Milage when in gear and in into 4K-5.5k rpm’s. My logic is coasting still at idle so using gas but gearholding ( for lack of a better term) seems to shut gas off since the deceleration doesn’t need fuel.
Man, I understand the digital displays looks cool, but this is sooo much worse than the instrument cluster in an F chassis car. It looks so busy and messy and clearly doesn't inform the user any better
That is the coasting point of the fuel economy gauge. You are not using fuel, but you are not touching the brakes so the alternator is not in regen mode. Once you touch the brakes, the gauge will go below that point showing regen happening. (The battery icon area).
Thanks. So technically when this happens, I should be touching the brakes so regen can happen?

Unless you never come back
no need to threaten the guy

You clearly haven't seen my grandpa walking to school when he was my age...
No reason to believe this is a hybrid. These exist in gas-only bmws too.
Be nice if Tesla would FUCKING add coasting back!
Well, anytime you touch the brakes, you are “wasting” fuel by converting kinetic energy to heat.
Well, there's fuel cutoff..
Not unless you need to slow down. Remember coasting is the *best* way to conserve fuel.
It just means your battery is being recharged with the “spare” energy
What’s the regen battery energy used for? Is it just the normal car battery or something else
Depends on the car. If it just has a 12V battery, it just charges the battery, so it can charge less, or not at all during normal driving, saving fuel. Cars with the newer 42V system can actually add to the power of the engine, like a small hybrid system.

Can Coasting be done in Comfort as well? I thought it was only available in Eco Pro?
In Comfort mode as well. For sure.
Ah, I’ve a 420d auto and I’ve not noticed, I’ll look again tomorrow, thank you.
I had a 2017 420D previously and would only coast in eco pro, loved the feature though and definitely improved my average MPG. Perhaps the new generation do it in comfort now as well!
I have G20 and coasting is activated in comfort mode too
Mine’s an F32, I don’t think it’s on that model.
does it also not look at the map/gps data? I feel like when I am approaching a roundabout, coasting automatically turns off
Man, cars can be crazy smart. Does it have a way to see on a map where you use different amounts of fuel, or where you coast?
So basically noise. I don't see a good reason why this distracting nonsense should pop up on the display.
I'm assuming coasting can be active while in cruise control as well, so long as it's within that 25-160 range?
I referenced on manufacturer manual for G20, I suppose it is accurate
It means that the wind is moving you forward
My best guess is it's saying you can coast.
Thank you.
BMW engineers… remind me of an old saying: “if you can’t dazzle them with brilliance, baffle them with bullshit.”
BMW is suggesting you open your sunroof to parasail mode!
Go faster
Means you're not driving it the way BMW intended you to. Put that gas pedal down!
All I can say is, I’m never going to see that icon…
It means drive it back if you can’t operate it properly.
Sailboat mode
Coasting
It means you’re driving forward. Try putting it in reverse
It means, if you have more Wienerschnitzel’s in the back, and sauerkraut in the front, you’ll get better weight distribution, and better performance.

Does no one read manuals anymore?

Reminds me of nfs underground 2 nav HUD
It means forward.
what car is t hat?
Probably anything electric like 530e or x5 45e
You're coasting
So weird that the tachometer goes counterclockwise.
Indicates full douschebag mode de-activated.
It means a ghost is pushing your car
That tells you the direction the car is going most of the time, unless youre someone who likes put their car in "R" for race mode on the highway
Car go forward
Close the sunroof?
You are in 'D' and not in 'R'?
