I just noticed the little LCARS interface sticker, I love it!
I saw you on the highway somewhere between San Antonio and Amarillo last year. I first read about this truck probably 10-15 years ago. Super cool. I wish I was able to get a pic.
so Do you press the button while your driving ? to turn off?
Please bring back the days of actual testing on Ecomodder !
Seems like a lot of work. You are no longer driving. You are focused on all these techniques
cool these look really effective
Ancient (14 year old video) RUclips gold. Thanks!
I’ve been looking to trick out my Prius the way the aerocivic guy did. If he can get 100 mpg on a Honda Civic then imagine what’s possible on a Prius! It would be amazing if you guys could do that and provide instructions and a parts list. Rideshare drivers and folks in gas-expensive places would love it.
I Drove 1200Miles in a Prius rental without doing the P+G and got 60+ MPG US Gallons . See Below Distance Driven 1204 (1937 KM) Gallons used 18.759 (US) 15.66 (UK) Cost (USD) $63.30 £51.04 ( Sterling ) @ Current Rate 1.24 USD -Pound MPG (US) 64.18 (UK) 76.88 3.66L per 100KM
Wish you guys aeromodded a Mitsubishi iMiEV. They paid zero attention to that little EVs 0.35Cd
Kinda skeptical ur car will slow down when generators starts to recharge battery. Thus no advantage over regular driving.
I don't understand how this works. Physics is physics. X distance, y time. Pulse, constant... Okay, wait. You can trick the engine off. Huh. But you're saving enough that stopping and starting the engine is still net positive?
It makes your car look ridiculous but it does work! Also if you don't care about fuel economy it probably makes your car faster too!
Very cool.
I would love to see a Toyota FJ 40 in the wind tunnel.
You weirdos have a dedicated channel?!
This is so freaking cool!
Neat! I wants it!
Darin, you are the original ! Hard to believe it's been over 14 years soon. Thanks for all the testing through the years.
It's more based on drag coefficiency on one vehicle to reduce drag and saved energy, but all things is a combination of things to work in union for better performance.
Eco modding is basically based after aerodynamics not much on fuel Technology are zero emissions, such as hydrogen fuelcell conversion and electric vehicles technology.
My theory is it takes advantage of brake specific fuel efficiency
Pulse and glide so passengers will puke hihihihhi
Empty road only technique. Anyone behind would be going bananas.
I have always wondered how well it would work, but never had the time or money to do it. This is perfect.
Newer Prius' free-wheel much higher than 43 mph, yep even highway speeds.
Imagine being behind this asshole.
Watch in 2x no words anyways
Boy, it sure is windy in there.
Yes Pulse and glide from 20 to 40 mph may give us 70 MPG and piss everyone else off behind us
Everyone gets stuck on “transmission” but its really a synchronized motor and engine in perfect harmony. Its quite amazing if you check into it
I wonder if a pulse and glide mechanism could be built into a car so that it does it multiple times per second. The engine could cause each cylinder to misfire by not injecting any fuel every few cycles to maintain speed but have the throttle wide open to reduce engine braking. The car will essentially be coasting whenever the engine isn't firing and since engines produce the best thermal efficiency at peak torque at wide-open throttle, you'd end up saving fuel without having to speed up and slow down all the time (at least, you wouldn't notice the speeding up and slowing down the car would be doing many times per second). Hooking this engine up to a CVT would be the most economical since the transmission could keep it in the peak torque band all the time. Further still, maintaining the vehicle's most efficient speed would add to the savings. Usually around 45-50mph.
I think it would be better to just not use some of the cylinders, although optimum results would be to be able to completely decouple the cylinders. This would be complicated in terms of needing two separate timing chains and a locking clutch in terms of evenly spacing the power strokes. The other problem is the firing order of a 4 cylinder engine makes it difficult to split up into two 2 cylinder halves that fire evenly. The other thing which is easier is to expand the range of top gears in the car. In most sports cars, the top gear ratio will be aligned so that the power peak and top speed are aligned on a level road with still air. At lower speeds, you can use an even higher gear. Perhaps a "drafting a truck on the highway at 55 mph" gear. In some cases the rpm you need might be below the peak BSFC but it will still get numbers adding a bit more load to the lower revs, than feathering high revs. In practice, these higher gears don't suit most rolling terrain driving conditions, but there are times where 1500 rpm at 70 mph might be optimal, in terms of decreasing the percentage of engine "rolling" resistance - especially if the engine is at least 1.6 liter.
@@TimpBizkit cars already have that....
dude must have an entire collection of tickets for impeding traffic....at least i hope
This is where people come from all over to learn how to piss people off on the streets driving at 20mph
Dunno why I like this so much, but it's awesome
Thanks -great video with good common Prius sense. Since I bought my car last year (had 165,000mi and a failed HV battery), I got about 44 immediately after fixing the HV battery and using it completely without hypermiling attempts. After I changed the oil and increased the tire pressure to 42front/38 rear I got to about 48mpg. After I figured out the ideal glide stuff (pressing pedal just a touch to get 'no arrows' or just lightly to get some battery power without engine kicking in, I was able to get my mpg up to about 50.x, with one section/one day oddly being up at 63 mpg over 150 miles highway and country roads. This explains, I guess how I got to that outlier high number. I must have been doing the extremely low engine-on 'pulse', where the orange arrow from the engine goes to wheels with no orange arrow from the electric motor to the wheels (meaning the motor is taking some engine power and sending it to the battery, also a green arrow.) It's a good tip that the driver suggests the instantaneous mpg number has been found to be 'about the speed your going' to maximize overall mpg. Thanks for that too! I'll be trying, when road conditions/drivers allow, to work on my pulse acceleration technique.
So the sperm was the same just the metro was going faster!! I want my 2:39 back!
Me on my way to uzbekistan
Hey look an Aptera
So I assume this project is more than dead..... Any chance the code is still lying around somewhere? Website is a no go.
for low speeds, pulse and glide is best (town etc). At higher speed, constant speed is also very efficient because of heretical mode.
That is totally wicked, I want to build one!
Can some1 recommend: is it more hybrid-efficient to brake slowly or step hard? Which would give a bigger output. Also, I've got a ct200h, the charge is more or less when the arrow is at 0? (the harder i brake - the lower it gets)
Braking gently is the best way to get the most from regenerative braking
Think of it more like time breaking not how hard. If you brake too hard you will be using the pads and all that energy is wasted you want to stretch your braking as long as possible this makes sure all the energy possible to be recovered can be. around 48% on a mild temp day
👌
And it looks so good 😜
I added a flux capacitor to mine.. I just have to remember to have a heavy jacket.
Auris MY15 Euro - best mpg 65.7 mpg or 3.58 l/100 km - how? 100% Eco Mode, always use the battery between 40% and 80%, always keep the needle at the half of the first eco section (on electricity or gas) always park your car with 40% battery life if there's a lot of accelerating and braking involved, use the battery between 80% and 90%.
With the aerocivic, I'll tell you what's funny, this car will probably beat all the boy racers' ricer on motorway races. Imagine an Aero Type R. Will it get to 180 mph? This could be used as a luggage carrier that actually IMPROVES your fuel economy!
At 4:06, he seems to undercut the entire approach for people who rarely drive at desired speeds (usually a tad higher than the actual speed limit) of less than 30 mph.
