When is the best time to shift gears for maximum fuel economy? In this video we look at how to drive efficient, how to drive with good fuel economy, and when to shift gears to maximize fuel efficiency. When you're accelerating and shifting through the gears, it's important to keep the engine in an optimal region where it operates most efficiently if you want to maximize fuel economy. This engine region is determined by an engine's brake specific fuel consumption (BSFC).
BSFC is a measurement of the amount of fuel required to produce a certain amount of power, for a given engine load and RPM. Generally speaking, BSFC is highest in high load, low RPM regions. This video will demonstrate this by conducting a test showing fuel consumption with the engine at four different operating regions, but with the same power requirement for each - to keep a car moving at 60 mph. Check out the video for full details, and to learn when the best time to shift is!

+David Crandon The engine is 25-26 years old with about 60k on it. It's an obd car running on an obd II ecu. I have parts and ecu from a newer engine and will eventually get around to making it distributorless. Single coil, inside of the disty, 7k rpm shifts, 3300 rpm at freeway speeds doesn't help either and wears ignition parts quick. But, lugging the engine seems to make it worse. 6 months to a year and cap, rotor, wires and plugs usually need a refresh. IF the distributor itself doesn't have an issue.

Your demo focuses on constant speed. In acceleration this is different, the engine is more efficient with an fully open throttle till 66% of rev range, then skip shift from say 2nd to 4th. Partial throttle can be less efficient. Just saying 😋 great channel btw.

7:26 This is just incorrect. If you accelerate in a higher gear, you will spend more time dumping fuel into the engine to reach the target speed. That's worse fuel economy, not better fuel economy. What's best for fuel economy is to accelerate at high RPM to get up to speed as quickly as possible, then cruise at low RPM to maintain speed.

Hey EE, I'm considering to apport some modifications to my car to improve fuel economy, and they most have to deal with the drivetrain and gear ratios. 1- My car has a quite high top speed (around 230kph), but only 5 gears, so when I want to be fuel efficient I find myself going like 90-100kph. So I was thinking, what about to pour in a new tranny with a 6th overdriven gear? How would I be able to calculate the benefit of that or knowing if the engine load is too much? 2- Another option is to change the final drive gear ratio, but unlike changing transmission that just adds a 6th gear, changing the final drive gear ratio would affect all the current gears, and may cause load problems on the engine in first gears. I'm really interested in the transmission change however, because why not, if I can go faster maintaining or even improving fuel efficiency, that's something absolutely worth it!

there are other considerations here he doesnt really address...in an internal combustion engine, particularly one without variable valve timing, there is a serious drop off of efficiency below max torque. The trick is choosing the appropriate gear for the load. It is quite sensible and reasonable to remain in top gear down to almost idle speed if terrain is such that accelerating back up above the magic 1500 rpm point that many engines start to lug at is easy to do because you arent climbing a grade or you have gravity helping you. I do it all the time and it saves a needless downshift and a measurable amount of fuel. But you have to be willing to accelerate very gently till you get above the lugging rpm for your engine. Be careful with this...puts lots of load on the engine at low rpm is not good, but if you are gentle with your right foot its amazing how low you can go without downshifting in some circumstances. In a turbo motor there are other considerations. Consider this: You are at very low rpm and apply heavy throttle and start building boost...Higher gear, high engine load, high boost, and now the real kicker...relatively low oil pressure comparatively speaking. What kind of agony do you think your engines bearings are enduring under that scenario? So my advice, if you are really trying to accelerate briskly in a turbo car, go ahead and grab the next gear and get some revs (and your oil pressure) up, your engine will thank you. Your pocketbook will thank me. :)

*Straightforward For Best Fuel Economy* 1.keep the engine between 2k and 3k rpm (for smaller petrol engines) 2.Perfect the craft of accelerating and breaking with the smallest amount of peddling travel (breaking it means break earlier and try not to scrub the speed that you have already gained by burning that precious fuel) 3. Let the car coast in gear as much as you can

I am confused, your bsfc graph says it takes this amount of load with this amount of rpm to have a certain amount of power. But what is that amount of power. Because most engines can’t make power at low rpms, they need to be up in the rev range to make efficient power. Even after the “lugging” stage. So I agree with what you said (to shift around 3000 and not go below 1500) but I believe it is for different reasons. Even if shifting at 1500 rpm wasn’t bad for your engine to even get up to speed you have a lot more throttle input for a lot longer time because there is no power there. So %60 throttle for 30 seconds in a high gear should not be as efficient as %30 throttle for 15 seconds in a lower. Obviously cruising 60 you should almost always be in top gear. I have no actual numbers so tell me if I’m wrong.

it depends about the car,the engine,if its diesel or gasoline...for example on my Seat Cordoba 1.4 Gasoline engine: I have to change gears at 2500 Rpm,and when I m in last gear(5th gear) at 90km/h the RPM increases again and passes 2500 Rpm which means higher fuel consumption. Something which you dont see at diesel version...

Look at the torque curve. If your engine makes peak torque at say 2.8k like the 2013 Toyota D-CATs, it’s probably a good idea to shift at that rpm. Reason I say this is peak torque is produced when the engine is at its most efficient, so if your engine produces peak torque at say 2000-2800 rpm you want to keep the rpms there while accelerating then shift up to the highest gear the engine is comfortable in, for cruising
Tim Polman
Tim Polman Месяц назад
I disagree. it depends a lot on the torque curve. on turbocharged engines, especially variable turbo, i agree (the 1.0 2019 polo i'm driving is most economical shifting at 2k rpm). however, my naturally aspirated Corrado VR6 is more economical by shifting at around 3500rpm, rather than shifting at 2000rpm. because the torque doesn't really rises a lot under 3000rpm. (straight six engine characteristic) (i'm averaging 25mpg in my 2.9l vr6 btw. including fast and economical driving. i can easely get it up to 30, but beyond that takes the fun out of it completely.)

Engineer here. - when going at a constant speed, use the highest gear you can for the lowest RPM - when accelerating, use the RPM ranges that has a higher torque/RPM ratio. Look at the RPM/torque graphs of your engine (the dyno tests give you these), and select the last RPM point, where the graph is at a 45 degree increase. That will be the recommended maximum RPM.

In my driving schools (Golf GTI) I'm supposed to use 1 for speeds up to 20 km/h, 2nd for 20 and up, 3rd for 30 and up, 4th for 40 and up, 5th for 50 and up, 6th for 70 and up for general driving. (which means when I'm accelerating for the Autobahn I'm supposed to go up to 95 in 3rd gear) Keep in mind: km/h, not mph. That means that at 59 mph (95km/h) I'd easily exceed the 70 km/h and should therefore use 6th gear I'd call that efficient. Btw: I'm usually at around 1800 RPM when switching up the gear

That's pretty interesting. Do you know gauges that measure vacuum in the intake manifold to determine optimal engine load? As far as I can remember some of old BMWs were equipped with such dial on their dashboard. There definitely were boundaries about amount of throttle to be open and wide open throttle doesn't always means high fuel efficiency. And there is one more aspect to mention. Low RPMs and high load are perfect prerequisite for engine oil starvation.

"And there is one more aspect to mention. Low RPMs and high load are perfect prerequisite for engine oil starvation.". I agree 200%. This is even more crucial in turbocharged cars, especially diesel ones.

Total garbage. Everyone knows that accelerating and braking is the killer of fuel consumption. The logical answer then is to accelerate at full throttle and not let anyone overtake, thus preventing ridiculous braking. Tyres releasing smoke also helps keep other cars away so try to do so whenever practical. :)

In my 6mt forester I noticed I can shift into 2 at 20mph, 3rd at 30 mph, 4th at 40 mph, 5th at 50 mph and 6th st 60 mph. I discovered this after plugging all my gear ratios into a spread sheet. I wanted each shift to drop the rpm to around 2000 rpm. I then noticed that each shift brought the mph to near what the gear number is.

Sometimes the more you try to save fuel the more you actually use. You become paranoid about using the accelerator and lift off unnecessarily, and in turn you use more fuel accelerating back up to speed again. Just drive smoothly without thrashing you car.

Incorrect. Often your mileage is worse when shifting soon. You have to understand that with a higher RPM the throttle valve doesn't have to be fully openend. (install a vauum gauge to see it for yourself) When you shift early, the low RPM and torque are in need of more air and gass to get the revvs up so the engine can pull again. This is when the throttle valve is fully open all the way. When you do this with a vacuum gauge, you will see the vaccum is dropped to 0 all the time untill the rpm and torque starts to kick in, then you see the vaccuum gauge slowly going to a higher vaccuum meaning higher RPM on highway driving is better for your economy. My jeep TJ 4.0 or instance. It revs near 2000 rpm at 65. But when I keep it in 4th gear it revs 2600 (give otr take) the fuel economy became better. Maybe new cars have a lot of lights and indicators, computers etc on board, giving you the illusion that early shifting is better...just try it for a while and compare your milleage, don't take my word for it.

Switching near 3000 is old. More modern is to gear up in the 1800-2000 region in normal day situations in average sized cars (compact cars like Golfs, Focus etc., from a european perspective of course ;))

I'm also wondering how this would apply to turbo diesel engines. My car only has a 1.5 litre Renault dCi engine, but with turbo and intercooler. I've always wondered, in particular, whether it's more efficient to cruise at the lowest possible RPM (where the turbo wouldn't be active) or at a higher RPM where the turbo is working most efficiently (which I think is at least 2000 RPM on my car)

I can vouch for that. It applies even more if you are driving a diesel as it makes a higher torque at low revs. Keeping the revs down can give incredible fuel economy.

Always impressed by your deep knowledge, you turn something upside down that I was led to believe by a trusted source long time ago. Their wisdom was, accelerate as quickly as possible to your desired speed and when there go to the lowest gear still safe/comfortable. The idea was that acceleration in the lower torque and power region of an engine would cost relatively much total fuel, even when consumption during a brief brisk acceleration is very high. So you say this is not true? And I have been living with a lie all those years? I think I'll keep the old version to justify down-shifting with rev matching to a gear that gives me the beginning of turbo power, and floor it. And between 60 and 70 m/h put the car on cruise control in 6, with over 60 mi/ga economy. :)

Heavy footers = poor economy. Light footers = good economy. It's not the only thing, but it is pretty much most of it. Changing gears sooner without gagging the engine can help you to achieve pressing the gas pedal lighter.

@Engineering Explained, what was model of the car you were driving and whether it was turbocharged or normally aspirated? In my experience, you have to drive turbos and NAs differently because of their engine torque curves. Turbo engines usually have a fairly flat torque curve but NA engines usually have a peaky torque curve for equivalent maximum power and torque. In my experience for economical driving with NA engines you don't want to rev the engine past its peak torque RPM, keep the revs up but with a lighter throttle. With turbo engines you can open the throttle to 100% at low revs until the turbo spins up and then back off to a light throttle. The other thing is don't lug your engine at low revs with wide open throttle, you will use more fuel, down shift to save fuel. For the most part, I don't use more than 40% throttle in general driving. Other things:- maintain your car with regular services (including air filter changes/cleaning) and check your tyre pressures at least weekly for tubed tyres, every 2 weeks otherwise. I suggest you also set your tyre pressures to the maximum recommended for your vehicle by its manufacture. Why? Your vehicle will brake and handle better, and be more economical. If you have fitted larger tyres to your vehicle I suggest you inflate them higher than the recommended pressures, you will have to experiment. What are your thoughts?

I wonder if the MPG that you see when you research vehicles, whether manual or automatic, is an average of the MPG on each gear, because in this video I saw a bunch of different numbers rather than just one number for city driving and one number for highway/freeway driving. Our 2001 Toyota Corolla CE Manual Sedan, a five-speed, gets up to 32 MPG in the city and up to 41 MPG on the highway. Although I was recently involved in a crash that wasn't my fault, and while it is still able to be driven (as the airbags didn't deploy), the other driver's insurance is marking it as a total loss primarily because of its age. Anyway, the replacement we are getting with the settlement is a used 2001 Ford Focus ZX3 Manual Hatchback, also a five-speed, which gets up to 25 MPG in the city and up to 32 MPG on the highway, so not quite as good as the Toyota on fuel economy, but if it's only an average, maybe it's not so bad. And it's still better than our 2002 Chevrolet S-10 LS Automatic 4WD Extended Cab, which only gets up to 15 MPG in the city and up to 20 MPG on the highway.

I drove my 1999 Honda CRV manual for over 8 years. Over time, I figured out that 2500 RPMs was the sweetspot for MPG. when I drove it, I keeped it around 2000 RPMs when going downhill and 2500 RPMs when driving Flat. It also made the car great for sharp back roads because it also has a short transmission because 2500 RPMs in fith gear is 50 MPH (which is also when it got its best fuel econmy of 28 MPG). Also, I learned if you want to get up to speed quickly for some reason, like going up a hill to merge on a highway, then you shift at 4000 RPMs. Any higher than that then your going to start buring a lot of fuel, any lower than that then you will be in fifth gear to quickly and not have enough power to get up the hill!

Does anyone else find that most cars that "suggest" a gear change for you are too aggressive with the low rpm high load thing? I've found specifically that when driving small engine cars in Europe, I'll be in 4th and the car will suggest shifting up to 5th while going up a hill, but if I do so the car won't be able to maintain its current speed even at WOT.
