The only advantage I can see in downshifting nowadays is in a performance situation with a rear drive car. You can control your weight transfer a little better and you can induce negative rear wheel speed which would likely get you a ticket. It is probably more useful off road but then again we have brakes for the rear wheels only now.
I hear of oil pressure dropping during braking if the trans is not in gear, especially during hard braking,anyone hear of this? 150+k on any given clutch I have, no matter the driving style.
Downshifting PROPERLY will very marginally wear a clutch (replacing 11 sets of brakes for every 1 clutch you go through isnt cost effective) and it maintains weight distribution better than a power braking system which delivers 70% of the braking power to the front. I agree fully that downshifting CAN be terribly hard on a clutch, but only when you're riding the clutch out like a 16 year old girl, or snapping it out without rev-matching.
Fuel economy aside, the purpose of downshifting is to give extra braking & avoid rotor/drum & brake material overheating. In town with a car it doesn't make much sense, but on the open road or downhill you would downshift for the same reasons a semi does. Brake material (including semi-metallic) will glaze over with excesive heat and the brake rotors will warp with extended application of brakes.
If u don't want ur clutch to go out then learn how to drive with a clutch right. Down shifting is bad if u don't know what ur doing. If wasting a clutch is that big of a deal start to do clutchless up shifting too. Good video tho.
With cars yeah you have some good points unless you match your RPM's before engaging the clutch, now a semi is a totally different animal not only is it recommended it is required especially if you have 45k pounds in your trailer. They are in fact equipped with a Jacob Engine Break that retards the timing of the valves during the exhaust stroke to put even more resistance on the drive train, this is such an asset that many heavy duty pickups now have an engine break as an option.
@mrwhite4 Absolutely true! But I obviously wasn't aiming this video at truckers, since those guys already know how to drive. LOL. Too few people realize the skill it takes to drive all that weight safely.
@floatingaxehead Well honestly want to pay 50 to 400$ to replace the brakes or 500- 1800$ or more to replace drivetrain parts clutches, crankshaft main bearings, drive shaft u- joints, transmission parts etc. The brakes are there for a reason! I agree with your video as i have been telling know it alls this for years. Eaton fuller semi trans are nonsycronized (super heavy duty), the clutches have at least 2 disk with a lot of friction material and 10 or 18 speeds.. They are designed for it!
@floatingaxehead I taught myself how to drive manual from being young driving farm equipment. From a start at zero i only use as much throttle as needed to get me moving and release the clutch slowly. Down shifting is not needed as a push the brake pedal while in gear to slow down and this greatly slows a vehicle down. I bring the engine to idle then push in the clutch and bring it to neutrl.letting off the gas in gear slows down a stick vehicle quickly when slowing down way ahead of your stop.
@floatingaxehead Oh definitely which I've been driving a truck for about 10 years and see so much stupidity on the road I've debated putting a dash cam on my rig just to cover my own tail. People see driving as a right not a privilege where they see the second amendment as a privilege now instead of a right. I tend to see things from that respective now, but yeah on a small German sports car it's silly. Nice car btw :) I wouldn't do a Hi point 'drag test' with that one :)
@remyramml While everyone in Europe does drive a stick, you're actually dead wrong on your fuel consumption theory. You're engine MUST use use fuel to move at a given RPM without stalling- we see this when the car is idling, right? If you're raising the RPM in an engine braking downshift, you're also raising the amount of required fuel to avoid stalling at that speed. If you want fuel efficiency, you need to go to neutral and let the engine simply idle while you brake manually.
@floatingaxehead I'm not a native speaker and don't have my Webster dictionary here... but in „Schubbetrieb” - that's when you are driving down a hill and using your engine to break for example - the engine basically is shut down in terms of fuel. Since mid 90s - when most of the cars used fuel injections - your engine uses less fuel than in idle. You can see that if your car shows your actual fuel consumption. It goes down to nearly 0.
@floatingaxehead just a quick note: a state of the art engine uses absolutely no fuel when you are above 1200-1600rpm depending on your model and starts injecting fuel when you get near your idle rpm. All without stalling.
@floatingaxehead actually not, there is a good tech talk about this with respect to F1 cars which now actually leave the butterflies open but shut off the fuel so that they can pump more air through the cylinders and into the exhaust to drive the defuser and maintain down-force into a corner. The fly wheel and momentum of the car will "drive" the engine and it is this tension between the engine (which isn't burning fuel thus creating drag) and the car momentum that creates the braking effect.
@remyramml In the old days, carborators had a bypass to send extra fuel to the engine when downshifting to prevent engine stall out. Todays electronic fuel injection is programed to behave in a similar way.
@MrBillTroop73 I don't know which cars you are referring to, but modern cars have what's called „Schubabschaltung” in german (which I think is called overrun shutoff in english). It interrupts fuel injection.
@remyramml Actually, the overrun shutoff is an air bypass valve that allows more air so the engine does not become flooded by the extra fuel sent through it's bypass. Thus preventing stall out during down shifting and sudden lifting of the accelerator.
@remyramml I tried a better translation, and, apparently you weren't talking abut overrun, but Deceleration Fuel Cut Off. DFCO doesn't engage immediately. The fuel and air bypasses I spoke of still send extra amounts to prevent stall out, even during rapid deceleration. Once DFCO engages, the engine becomes a heavier drag on the drivetrain than an idleing engine would. This may give you a small fuel savings, but that is not it's intended purpose, and not as much savings as you believe.
@chickomenon You're right, but how many people are really as good a driver as they think they are? How many honestly know the proper RPM for each gear at a given speed? I'll freely admit I couldn't do it... LOL. I downshift to drop (several) gears to accelerate...
@floatingaxehead Anyway.. You're point is very valid.. In an automatic car, when you use the brakes, the engine is always trying to propel the car in some way, 'help it along'.. There is NOT a NEED to downshift new manual transmission vehicles. Simply leave it in the gear you're in for safety or put it in neutral and apply the brakes and I assure you you will safely come to a stop.. haha.. great videos btw..
Exactly what I told my father years back. He usually had a vega or chevette or some rice burner. He would downshift through all the gears at every stoplight. Used to make me a little carsick...
I used to watch your gun vids on a diff channel. Glad I found you. Good Day !!

Up here in the northeast even so much as a turn signal is seen as " giving away vital secrets to the enemy".
Slowing way down without the intrusion of brake lights is the equivalent of black bag opps.

Sorry... but you are wrong. Downshifting will also reduce your fuel consumption as it goes to nearly 0 liters/100km.
Why do I know that? I'm european and therefore driving a stick since I have my license (like everyone here).
Everyone here is downshifting and there's no significant clutch wear.
