    It's not how hard you are on the gas pedal that matters for economy, it's how hard you are on the brakes that really matters.

    • @MeynMotorGroup
      @MeynMotorGroup  2 года назад

      So I know that being hard on the brakes is bad for fuel economy as opposed to letting off the throttle and gently coming to a stop, but can you explain to me why you think hard braking is worse than flooring it/hard driving?

      @@MeynMotorGroup So a quick disclaimer, how fast you accelerate does make a slight difference in fuel economy, but ultimately, a combustion engine converts fuel to heat and kinetic energy with some ratio, and that ratio is the thermal efficiency. Modern vehicles (drive by wire equipped and to an extent all fuel injected) with automatic transmissions tend to keep the engine at the rpm that is closest to maximizing the thermal efficiency for the amount of power requested by the driver. The thermal efficiency curve (when isolated to only the combination of engine load and speed that yields the maximum, so we ignore situations like flooring it at 1100 rpm and barely touching the gas at 5500 rpm) has a peak usually around 2000-2500 and the area around it tapers off slowly. So you actually get the most bang for your buck when you are driving with a decently high engine load at around 2000-2500 rpm. That is, you get the most kinetic energy from your gasoline. The more you deviate from that range, the more heat you produce rather than motion that goes to the wheels, so yes, driving very hard does cost you a little more fuel.
      The main reason rate of accelerating doesn't change efficiency very much is that it takes a relatively constant amount of fuel to pick up a certain amount of momentum, to bring the vehicle from one speed to another. Once you produce that momentum, you can hypothetically coast on that momentum for quite a distance. Not forever obviously, friction and air resistance will always slow you down, but you can travel approximately between 1 and 2 MPH^2 in feet on flat ground. For example, if you're going 70 MPH, you should be able to travel between 4900 and 9800 ft on momentum alone if there is not a hill to slow you down or speed you up, and nothing like wind resistance. Low drag vehicles (fwd sedans, etc) will be on the higher end and high drag vehicles (4x4 suvs, trucks, etc) will be on the lower end. This is assuming wheel horsepower is 0. When the car is idling and the automatic transmission is in gear, at speeds below 4 mph, wheel horsepower is between 2-10 depending on the engine/trans, so we assume that car is shifted to neutral around that speed.
      If you floor a 4 cylinder midsize car and get up to 70 MPH, you'll travel roughly 1000 ft in 14 seconds burning an average of 8.0 gallons of fuel per hour, and burn roughly 0.03 total gallons of fuel. At the instant you reach 1000 ft distance traveled, you have an efficiency of 6.3 MPG, and if you were to immediatley slam the brakes and come to a screeching halt after 200 ft, you'll have traveled 1200 ft total and burned a trivial amount over 0.03 gallons, for an overall efficiency of 7.6 MPG. If you were to immediately release the gas and coast 9800 ft, you'll have traveled 10800 ft total and burned again a trivial amount over 0.03 gallons, this time a touch more because the engine will have spent much more time below the speed where it must inject fuel, so closer to 0.033 gallons this time (adding 0.3 GPH x 40 seconds of idling). But your efficiency in this scenario would be 62.0 MPG. 62.0 MPG sounds high, but we are talking about a pulse and glide type of driving where you are not wasting any energy through the brakes, so on a treadmill, this type of economy is not ridiculous when employing this technique on a low drag midsize car. The reason you will never see 62 on tank, is because cars do cold starts, they idle, run accessories, you have to brake for traffic, you have to park, etc. All those things add up.
      Now let's say you accelerate gingerly to 70 MPH, maybe 1/2 throttle where you keep the engine RPM between 2500-3000 RPM. You'll have traveled 2000 ft this time and burned an average of 3 gallons of fuel per hour for approximately 30 seconds, and burned a total of 0.025 gallons. At the instant you reach 70 MPH, you'll have an average of 15.2 MPG, and if you slammed the brakes similar to the scenario above and slowed to 0 in 200 ft, you'll have an MPG of 16.7. If you instead didn't brake at all and coasted down to a stop taking 9800 ft to do so, you would have burned about 0.028 gallons but travelled 11800 ft, for an average MPG of 79.8.
      When you compare braking as hard as possible to not braking at all, the difference between full throttle acceleration and accelerating gingerly was +120%, but the difference between accelerating gingerly and full throttle when not braking at all, was only +29%. *When you don't brake, the amount of additional fuel you use by accelerating in the most wasteful manner possible compared to using the engine in it's most efficient operating range is only about 30%.* The more you brake and the harder you brake, the bigger the delta.
      It's actually more efficient to floor a car up to speed, and let off the gas and coast to a stop than it is to accelerate really slowly and then slam the brakes at the last second. In general, you want to brake as little as possible to save as much fuel as possible. This can be achieved by increasing your following distance between yourself and the traffic ahead, and "defending" that following distance by releasing the accelerator pedal once you see traffic slowing down. You also have to learn how to coast. The distance you can travel increases with the square of your speed, so you can coast 4x farther at 2x the speed. Not only will you save gas with this method of driving, but it's also safer since you are paying more attention to what's ahead of you, you're increasing your following distance, and you're also saving wear on your brakes.
      Whenever you brake, you are wasting energy that the engine has already converted from fuel, and must replace again with more fuel. Whenever you coast, you are mostly driving for free. As you saw in my example above, the most extreme difference in braking vs coasting was between 380% - 715% (62/7.6 -1 and 79.8/16.7 -1), whereas the simple difference between medium and fast acceleration was 29% - 120%. This is why I say how you brake is more important than how you accelerate for economy.
      It is extremely wasteful to accelerate quickly in a short distance and immediately slow down than it is to accelerate slowly and not have as much momentum to start with and therefore have created less momentum and therefore used less fuel before needing to slow down. This is mainly where the concept that accelerating hard does damage to fuel economy comes from. If you have 2000 ft to travel from stop sign to stop sign, you can pick up a lot more momentum and therefore burn a lot more fuel in that distance if you accelerate quickly rather than accelerate slowly. But if your goal is to get up to speed and coast without using brakes at all, it doesn't matter much how fast you pick up speed since that's a tiny portion of the distance you will end up traveling.
      If you watch my borning, low production quality videos, you'll notice that I tend to accelerate rapidly from a stop but I am very slow to decelerate if traffic allows and I get at least 50% better than EPA ratings on all my vehicles.

      You put so much effort into this response thank you, I read the whole thing. I see what you’re saying if there’s not too many stop signs coming up it doesn’t really matter if you floor and just start costing but braking destroys the momentum the engine has already built.

    Informative video! I would have added that driving at or slightly below the speed limit at highway speeds drastically improves efficiency. I was able to achieve 42 mpg on my Honda HR-V by driving like a grandpa and staying at or below the speed limit. This was mostly done on a Highway loop. You made a good point about turbocharged engines- the key is to stay out of the turbos which is difficult. I was able to achieve slightly over 25 mpg on a GMC Sierra 2.7 turbo by driving carefully on the highway. Drafting behind tractor trailers didn’t hurt either. Not the safest thing to do as it requires the driver to pay close attention. Drive at your own risk!

      @@kalmmonke5037 Turbocharged engines produce lower emissions BECAUSE they burn less fuel. Automakers have CAFE standards (fuel economy) and emissions standards (CO2). Smaller turbocharged engines achieve both better MPG and CO2 numbers. Saying small turbocharged engines are made solely because of emissions is inaccurate. Both factors play a part. Maybe it’s different in your country.

    Great tips for mileage, I wonder if this twin turbo is the same as the LS500, I would presume so. The slippery LS500 returns excellent mileage on the highway and or with a light foot. The Toyota 5.7 is just so good, maybe not on fuel, but in every other way. I was in my friends 21 Tundra a couple weeks ago, it is just magnificent. The V8s are going to be gone, the turbo and or twin turbo sixes are just the popcorn on the trail to EV I'm afraid. The good V8s, my favorite being the last GM LS, and Toyota 5.7 are just the best driving experience in creamy torque that will ever be and is now extinct. Turbos do not like aggressive driving is very true. Most people buying the LX600 or LS500 are probably not driving aggressively, I think my LS has been "floored" a few times when my bride was not present. Great review, keep em coming, I'm still road tripping a last year Trans Am, loving it.

    Some other tips, don't carry any unnecessary items in the car, extra weight = more fuel, try and imagine your throttle pedal as connected to your wallet and everytime you push it it's pulling dollar bills from it, and coast whenever going down hill, take your foot off the gas, and you'll be surprised at the difference these little things can make!

      You can ask them what the ES availability is they are located on Washington DC but you can have the car shipped for a price. If you are going to go down that path, I would go for an ES300h since it is equally as smooth but gets 40 mpg city and highway
