An important point worth mentioning is the safety aspect. In every scenario I can think of, engine braking is safer than coasting in neutral. When you're in neutral, you just abuse the brakes as it's your only way to slow down. Not only does this wear out your brakes way more, but it also drastically reduces their ability to slow down your car in the event of an emergency (especially downhill). In other scenarios, you might need to use the throttle to avoid an accident (say a sudden obstruction in the road). Having the car in gear means you can act instantly, while having it in neutral puts a small delay before you can accelerate to avoid an accident. I find that the car behaves a lot more predictably when in gear than when it's coasting in neutral. Plus, being in gear allows you to use throttle to correct slides/spins in low-grip scenarios. You just have way more control over the car when it's in gear, which naturally makes it safer. Personally, I'm willing to sacrifice a couple mpg for this reason (and to save my brakes, which could partially offset the cost of 1mpg difference).

does using engine breaking wear anything else down? like gears?

@maremike2691 4 ай бұрын

@@1EVE1X Not really. The breaking itself happens by a vacuum occurring due to the fuel not being injected and the engine still rotating. But the downshifting itself could wear a clutch a bit, but clutches do not really wear unless theyre overheating. And overheating occurs in extreme scenarios, where youre holding the bite point too long while upshifting and applying gas, or holding the bitepoint too long while downshifting in a really low gear for the current speed at which youre at.

@@adarob92 Starting in 2nd is only viable in a couple scenarios, first gear is too short and your car has too much power, and/or your car has a lot of power and you're driving in snow so starting in 2nd will give you more control. Although with proper throttle and clutch control you probably don't need to start in 2nd when driving in low traction condition. My 158hp civic can start in 2nd gear, so you don't need a whole lot of power to do a 2nd gear start, but I don't recommend it as you'd have to slip your clutch longer which will put more wear on your clutch. Your driving instructor probably burns through his clutch every 30k miles, downshifting without rev matching too? Yikes..

I agree. Ive been reading the comments and paid attention to your explanations and you are right. Engine brake for stopping or keeping the car at a reasonable speed down a hill, coasting for when engine brake is too much brake (less likely scenario). Maybe in some hills engine brake or coasting is not the better way but it is to lift just a bit. I hope I am comprehensible.

@rayjennings3637 6 ай бұрын

Having been taught to drive in 1966 by driving a 3½ton Army Bedford, engine braking was paramount. Up until a year ago - 2023, when I bought my first automatic, engine braking was my preferred driving method and it always meant that I was probably already in the correct gear for the moment when I began to pick up speed again! There were times however, when, as a poorly paid soldier, I would coast at every opportunity.

@grigorvalchanov8083 6 ай бұрын

Important thing to notice when going on big descents regarding coasting vs engine braking. There are very steep mountain roads near my city and it seems like a lot of people get confused when it comes to going downhill, especially on steep tight turns etc. The best & safest way is using engine braking on a lower gear and higher rpms so you get more "engine braking". Otherwise if you coast down the hill you'll wear out and overheat the brakes in no time which is a big no no. Using the engine as main braking source means you'll have to use the breaks less and it still uses no fuel. On newer cars injectors shut off automatically and spray no fuel when engine braking.

Added to this, one can argue that an added benefit of coasting is that you're putting lest stress on the engine. Depending on the speed and the gear engaged when engine breaking, rpms can stay quite high when coasting just keeps the engine at a steady 800 rpm or so. Much nicer to the engine.

@TimpBizkit 4 ай бұрын

Engine braking doesn't use fuel while you're using it (above a certain rpm), but in neutral you can begin the slow down earlier without the car going too slow. So use engine braking on downhill and low speed limit at bottom and coast when you can keep going. Some people turn the engine off to coast to get the best of both worlds but can be dangerous in certain circumstances. I mean you can fail your driving test for extended coasting, but it does have its uses for lowering your rolling resistance because you are not moving those engine cylinders up and down as quickly when you don't need them. Sure you are using a bit of fuel to keep it idling but you don't have to accelerate as much when you finish the coast.

You can control the amount of engine braking to be induced by not letting off the throttle entirely. There's a sweet spot just lower than that of maintenance throttle where the transmission gets unloaded the most while still remaining connected. This can maximize the glide effect without sacrificing the safety of being in gear.

You can safely brake with your gearbox as long as you a) don't downshift more than 1 gear and b) release the clutch petal just to the initial biting point and then immediately press it down again. I have 350,000 KM on my C220D and the gearbox is just fine. As for coasting vs Engine braking.. the later has the transmission engaged which means mechanical resistance, friction etc so naturally you slow down. Finally, one should never drive in neutral or with the clutch pressed.

Yes, but you are using coasting in wrong situation then. If you need to slow down more you never use coasting because it wastes fuel by idling and also uses brakes more. Engine braking is the only correct option for this situation. On the other hand there are situations when it is clearly beneficial to use as it reduces engine noise and increase economy. One clear example is when you are going down a hill with a gear in and you are losing momentum so you need to apply some throttle. But if you were in N you would stay in desired speed or even would be accelerating slightly. That situation doesnt wear your brakes because you dont use brakes on straight road just for no reason you are just conserving fuel and reducing noise. This is easy example when is is just beneficial to coast.

The idea of engine braking in modern trucks and coaches still exists , although most are automatic and the retarder ( electric Thelma brake ) does most of the slowing .

@ds-1111 Ай бұрын

Wait, why do you believe no fuel is entering the engine when you are engine breaking? The throttle body isn't a perfect seal, it allows some air to pass for idling. Your car is basically still trying to idle when you are engine breaking. The MPG measurement on the car is measuring how much fuel is injected over the distance traveled. Since coasting and engine breaking are both attempting to inject the same amount of fuel (attempting to idle), of course engine breaking is worse MPG because you slow down faster and travel a smaller distance while injecting the same fuel as coasting which doesn't slow down as fast and travels longer distance. I do know about DFCO, but doesn't that really only kick in at higher RPM ranges?

@MickDrivesCars Ай бұрын

DFCO is used at all RPMs above idle. It'll stop once you get to ~1000-800rpm so you don't stall. This is obviously for modern, fuel injected cars.

I don't like to coast, because you don't have immediate control over the car. You have to put it back in gear to accelerate. I would put the car in cruise control to maintain the same speed. The car can than decide to engine break or to help out a little by putting a bit of fuel in. The cruise control wil put the tiniest amount of fuel in to just prevent it from creating a vacuum and engine brake. That should be the same amount of fuel as to have it running stationary. It's very hard to balance that amount with just your feed, because you react to the feedback of the car (increase of speed) but that will add way to much fuel.

"Engine braking is not" *describes exactly what engine braking is* Also most, slightly older, cars do not cut off fuel flow to the engine. That's a mostly modern feature, in an older car you are much better off just using your brakes.

The highest gear is still running at such a high RPM rate on 6th, and pushing it into neutral drops the revs so significantly it's reducing drag in excess of the force pumping into the engine. If this is the case, the 8 speed automatic should yield different results.

This is a weird comparison. Coasting is something you can do to save fuel. Engine breaking (it's in the name) is something you can do to save your breaks. It's very useful in mountains, where people not using engine breaking can genuinely have breaks malfunction (if you are on the break for half an hour on a steep mountain and your breaks are not in good condition). Using engine breaking to save fuel (how even? You speed up couple of km above your target speed and let it slow down by engine breaking to the target?) doesn't make sense, just leaving the car at target speed must be better or same. Obviously if you need to slow down a little, i.e. due to traffic slow down, then by all means it's better to use engine breaking (lift your feet off the throttle) than the actual break. But mostly you just won't wear your breaks as much. Don't expect better fuel economy, maybe just due to the fact that using engine breaking, you are less likely to break more than you need.

@NetVorTec 6 ай бұрын

Great video but there's no baseline... you need to re do it with "normal" driving, keep speed (cruise control?) and only brake when you legally have to start braking (no engine braking, no coasting - obviously you can't not engine brake but use your foot brakes as the main source of braking)

I may be wrong. But I have an impression that engine consumes same volume of fuel when we lift our foot off completely. This is idle level of consumption and engine never goes lower than that. You would need to shut it down to consume zero. But it will probably start back again, being turned by wheels, if ignition is on. Let's do imaginable experiment. Do engine brake until full stop. It will never stop, once it reaches balance between initial consumption level and resistance and will slowly drift at about 5-10 mph. But if consumption was zero, it would stop eventually. While coasting, you go by inertia and will definitely stop. And you can really switch engine off and go large distance from a hill with zero consumption. Only it is considered not very safe as wheels are not engaged with the engine. So, you always consume idle amount of fuel while coasting or engine breaking. On high speed engine breaking slows down, but at low speed it helps to keep the speed and distance will be longer (as long as you can wait actually).

@@Moñin02Difference should exist. It should be less consumption for coasting. How much less? Depends on everything. For 6th transmission it is close to optimal for the engine at 70 mph, so it makes less resistance, not much of a breaking. But if selection was 4th, it would slow down much faster. And coasting would win a greater deal. But you would need to boost high rpm first in order to swich to 4th transmission, then release the gas.

Please mind my English.. In my opinion, when we lift our foot off from the gas completely and the revs are in about more than 1,200 RPM, the injector cuts off the fuel. I did an experiment, I was coasting a decent downhill on the 3 rd gear (or may be 4 th) and I turned off the ignition while in gear. The car or the engine doesn't make any difference at all. And when I press the gas the car began to slow down more because of more air compression.

Google DFCO "Deceleration fuel cut-off" Your (modern, fuel injected) engine uses 0 fuel when engine braking.

DFCO is indeed present with all modern engines and it kicks in when lifting up until the engine revs go below the idle speed - when it deactivates. If your car doesn't display an instant consumption (to help see how this works) this can be easily checked with a cheap OBD reader and an app like TorquePro

Hey! Id love it if youd add things like MPG also in L/100KM somewhere in the screen like in most parts around the world. Same goes for mph when its essential to what youre talking about. :)

Love this comment! I will 100% be adding those in future. Just never thought about it!

Mick, Please keep both hands on the steering wheel, my Mum and Dad were both very safe drivers, they taught me to do this when i was learning to drive. 😉 Au

He's done a video on this that's definitely worth watching. It's really not neccesary all the time, and you should alter your hand positions depending on the situation.
