@@elixier33 I said he did a good video explaining what's happening, not on exactly how much fuel he's saved. The trip computers have access to the injector pulse durations (and thus fuel quantities since this will be characterised during manufacturing), deviations, aging information, etc. As a result the trip computer will have plenty enough information to give an accurate enough estimation of instantaneous fuel economy. This is what he used to illustrate that a car rolling in gear down a hill is using less fuel than the same car rolling down the same hill in neutral. It shouldn't take much for someone to extrapolate from that that he'd be using less fuel long term by not coasting. You're correct though that to quantify the exact volume of fuel saved, he'd have to do a tank fill-up comparison; however, that's not what he was doing, nor is it necessary to illustrate the point, as I explained above.

Thank you for making this video! As a hypermiler, I coast all the time and it works for me. People seem to think that coasting always uses more fuel since the engine is idling instead of in decel fuel cutoff, but they ignore the fact that engine braking also slows the car down just like riding the brakes does which isn't usually wanted when hypermiling. Coasting a long distance getting several hundred MPG can add more to your average than engine braking for a short distance using no fuel. But of course stay in gear and take advantage of decel fuel cutoff if you need to slow down or not pick up too much speed, no reason to coast if you are going to be braking. When people say I'm wrong and don't believe my test results, now I have an excellent video to point them to :)

@@Oxymorone7 Yup. Coasting can definitely save fuel in some circumstances, but not all. Unless coasting is causing someone to pick up too much speed and brake a lot, which isn't when coasting would be beneficial anyways, I don't see any safety hazard. People say the driver loses control when coasting because they won't be able to accelerate immediately, but being in a high gear isn't going to be much better. Realistically, if fast acceleration is needed, downshifting will usually be necessary. Shifting from, for example, 6th gear to 3rd gear for maximum acceleration isn't going to be any faster than shifting back into gear from neutral. But with automatic transmissions, especially ones with a significant delay going back into gear, that could certainly be a valid argument.

Explained very well. Engine compression braking certainly works a lot better with modern injection units being able to completely shut off. It's rare to hear exhaust popping from unburnt fuel when cars pass you downhill these days. This is the main reason why I favour braking in one gear until I reach idle, or selecting a gear just before needing to apply the gas.
@ConquerDriving
2 жыл бұрын
One small correction you may be interested in. The compression doesn't actually cause the engine braking as it's equalled out by the expansion of another piston. It's actually the vacuum created from piston to closed throttle body that causes the majority of the braking. It's technically vacuum braking. I used to believe it was compression also until I found out otherwise.

@@ConquerDriving Yes, you are correct and I'm fully aware of this. I use the term very loosely without opening a can of worms and getting into a full dissertation on the subject🤣. I refer to this method alot when explaining old school braking through the gears. Back in the days with carburettor cars, as they naturally had an overrun and therefore require the induction to be almost cut off. Although still true with modern cars, they also have the ability of a "no power stroke" to cancel the compression stroke. Due to the fact the fuel is cut off. Hence, no reason to brake through all the gears. Plus, it all gets messy when we start to consider kadence effect, inertial/angular momentum and so on. Also, older diesel engines didn't have a throttle body, so it was simply managed through the fuel starvation and stoichiometric ratio. Since the introduction of Egr regulation systems, turbos etc, this has all now changed. Another argument that pops up alot is, why don't diesels have good engine braking considering the compression ratio is higher than petrol cars? Consequently, the "vacuum princible" does explain this well.

You know who is driving 2,80€ per 100km ? , electric cars . So when u r coasting u basicly have electric car fuel consumption .

Coasting saves a lot fuel when you drive at low speed, bellow 15 mph.

For me (I'm from Serbia) is much logical to measure fuel consumption in l/100km so lower number is better, and my car (VW Tiguan) can measure consumption even when is stationary, the unit is l/h then. And when I left car in gear and let off the gas pedal it is showing me 0 l/100km. One more thing: coasting with car in neutral is not safe for breaking. If you lose your breaks for any reason (break fluid leek for example) if car is in gear engine will help you break, but if car is in neutral it will be very hard to put it in gear again if the car starts to speed up on downhill.

Wouldn't this only apply if you lose brakes and have a open strech of road for you to slow down using engine braking? Probability of hitting that conditions is pretty low as: 1) There mostly always is traffic on the road. 2) Other drivers almost always assume you have breaking and base there driving decisions on that. The only difference between the two is that when coasting in neural and you lose breaking, you should have the ability (or smarts/quick thinking) to select the right gear and then keep downshifting if immediately required. Am I missing something here?

Respectfully, this is incorrect. If you were to coast without braking in both instances, at the bottom of a hill you've more potential energy in forward momentum when coasting, as opposed to heat in the engine (or brakes). This is then fuel you don't burn when accelerating or beating wind resistance, that's where you gain your MPG. Granted, this efficiency of driving is hard to achieve whilst using British roads in a safe and considerate fashion. I'm sure you know this, because this is what makes regenerative breaking useful.

Does the car have to burn extra fuel to cancel the force slowing down the car by releasing the pedal that wouldn't have been burned if you were in neutral? That's why I thought if you were driving in a lower gear the engine is just "fighting" itself using extra fuel to cancel an engine resistance force I don't need. I suppose opening the throttle would move some of the losses out the way. If you have to slow at the bottom of hills (or keep braking to maintain a safe speed) it's worth just staying in gear to remove the idling losses unless you turn off the engine when going in neutral, which will make the brakes less effective after a few uses. I did have a Citroen C2 that didn't engage DFCO until over 2000 rpm so sometimes I'd alternate between a low gear and coasting. Coming down the hill to Llanfihangel Nant Melan is a good example because it's a long hill with a 40 at the bottom, so unless you're going to blow through the 40 like a sinner, you are better off staying in gear and it only scrubs a bit of speed off the descent and you're still over the speed limit at the bottom. Also the hills going down into town from Bath university. You'll get to 40 on a bicycle in a 30 on the least steep hill (the others I chickened out and used the brake due to not trusting traffic conditions). So I imagine a car could get rolling to 100+ if you could keep it on the road round the corners and you didn't cause an accident. Also there is a roundabout at the bottom. So that is another hill you'd probably stay in 2nd or 3rd, though electric car owners will get a decent bit of charge back in the battery descending the 150 metres of elevation.

A motorbike will be similar but it's very important to put safety first. Briming the tank makes no difference to the fuel economy trip computer as it doesn't work it out by what's in the tank but by how much fuel flows into the engine.

My bmw 2 series turns the engine off when coasting, it does it automatically when you lift off the accelerator, as soon as you touch any pedal the engine kicks back in. So if you hit the brake cos ur going to fast down a hill the engine provides braking while still not using fuel. Obviously if you hit the accelerator the engine kicks back in so you can accelerate. Interestingly in eco pro engine mode the car will allow some gentle braking before the engine cuts back in, on comfort the engine kicks back in as soon as you touch a pedal. In sport the coasting feature and yhe start/stop system in general are disabled.

I have question: If you go downhills with some gear and breaking by engine, boardcomputer shows "---"but from the exhaust goes the burnt petrol (or diesel), you can see, hear and feel it from the cars front of you. And, if this would be truth, you would not be able to start the car by pulling in case of drained battery. So, how it is possible? You surely don't go on gravity. Because otherwise you would feel the start of engine, similar to Stop/Start function. So, even in engine breaking, you have some fuel consumption and it is the same situation as if you stay with engine on. Usually, engine takes 1 liter per hour on idle speed. In math: if you stay, you cannot divide by zero, so 1/0 makes mathematically no sense. Analogically, if you travel 100km/h downhills, you have real consumption 1/100=0,01l. But for marketing reason is nicer to write "---". Or I am wrong?

When you're off the gas, the engine's ECU (computer) cuts fuel and the revs start to fall. When the revs reach idle speed, then the fuel is reintroduced to prevent the revs going too low or stalling.

There's 1 more variable I think you left out towards the last comparison. Yes, coasting was more efficient than using cruise control, because cruise control applies the brake often, since it aims to keep you at that speed and doesn't let you go over it, whereas coasting will let you go a bit faster. If you compare coasting vs driving normally and not using the cruise control, you might get similar results to coasting because people will normally allow the car to go faster without applying the brakes all the time. Overall, I agree that the benefits of coasting to save fuel economy is not that much to make a difference and definitely not worth losing control of your car.

Great video as always, my only question would be that on that steeper downhill example, the car is using no fuel, I've heard this is because the car's computer will cut fuel and allow gravity/momentum of the car to keep the engine spinning. Is it right? I'm not sure how to check whether my car has this capability or not. It is 15 years old but I do have a current and average MPG trip computer like you used in the video. So will have to give this ago like you did.

Coasting in neutral does not save fuel when: *Actively slowing down *Downhill slope excessive to maintain safe speed without speed control measure. Coasting in neutral saves fuel when: *slowing down early without brakes *able to maintain safe speed traveling downhill that would otherwise require engine power in gear Coasting in neutral saves fuel by allowing the engine to operate at idle speed, which has less resistance than all higher engine speeds. Imagine you're going down a hill at 60 mph, and you can shift to neutral and maintain 60 mph. Your engine would be at about 750 rpm or so, and at around 0.25 gallons per hour (60m/h / 0.25g/h = 240mpg). Now imagine you shift to 5th gear and now you're at 2400 rpm, and you set the cruise control to 60 mph going down the same hill. The engine will burn enough fuel to overcome its own resistance, which would be close to 0.80 gallons per hour, and you'd be getting 75 mpg instead. We established that you can coast down this hill in neutral, which means the wheel horsepower required to maintain speed is 0. When the engine is spinning at 2400 rpm while in gear, there is a resistive force that would cause the car to slow down, and in order to maintain speed, you'd need to use fuel to overcome this resistive force, enough in fact to acheive 0 net wheel horsepower. Essentially, by staying in gear while maintaining a speed you could otherwise maintain while in neutral, you are simply revving the engine for no reason. If this scenario happened perfectly where you were pushing the gas just enough to maintain speed when you could be in neutral and still maintain speed, you could push in the clutch and nothing would happen, no change in engine or wheel speed. However, idling the engine while in neutral does use some fuel, and engine braking uses no fuel at all. Therefore, if you must slow down actively or maintain a safe speed traveling down a steep hill, it is more fuel efficient to be in gear and take advantage of deceleration fuel cut off and use the net braking effect to save both fuel and wear on the braking system.

The trip computer has no idea how much fuel is being used it's just an estimate. The manual even tells you so. If you want to know if coasting says you money then you have to actually drain the fuel each time or put a set amount of fuel in so you know 100% without any doubt what what because you have no idea if that computer is lying to you if it's accurate you just don't know until your whole video is basically garbage. I don't mean to be a shell but it's the truth and the truth is your car doesn't really have any idea about it's fuel usage and so you don't either. If you're going to make a video make one accurately measure the fuel control the variables do it properly..
