Mythbuster did an epic series of this tests many years ago. Tailgate up, down, and removed. Most efficient in order: up, removed, down. Tailgate up creates a vortex bubble in the bed which pushes passing air over the truck most efficiently.
The benefit should be visible with a fastback shaped like cover like we can see in some pickups like the 2010 Navara.
I do not know if anything exists for this one tho
ruclips.net/video/r3aqHbD-O9E/видео.html
except that in Bjørn's test there was no measurable difference.
Bjørn was very smart to repeat the tailgate up test. This “capping run” is needed to prevent wrong conclusions due to test-to-test variation due to uncontrolled variables. The results show the importance of this step. I appreciate Bjørn’s efforts to conduct all of his tests in a scientific manner to get the most accurate and meaningful results.
I wonder if getting a bed cover would improve efficiency
You have to clode the tailgate to save energy, that limits zair flow going into the tail, mythbusters made a great videos explaining and measuring it
When I see 'shocking' in the thumbnail, I know it's a youtube video :D.
Takk Björn för ännu en intressant video! :-)
“There’s a little cowboy in me” pause on that
His fave movie is brokeback mtn.😊
@@Macmonkey1000 hahaha
Thats proper testing 👍
Cool test!
Very interesting 🤔🤔 good rest. Keep up the good work 💪🏼👍🏼
Mythbusters already tested this! Lid closed is more efficient and your test kinda proved that. ABC! Always be closed...
hadn't this been Mythbusted already? ABC, always be closed.
Hilarious that its estimate when you turn it on is less than half the consumption it actually gets.
Please test smart #1 premium one motor and brabus
I see that many people agree that counter-intuively the tailgate makes very little difference..
But if it did, wouldn't you be as likely to see it in the time of the runs or the satellite speed at given points on the run since the power is limited? Wouldn't reduced air resistance show up as slightly faster speed?
The tailgate can be changed for a net, those are (were?) on sale for ICE pick-up trucks. I used one on my ICE Toyota Hi-lux in the 90's, and it worked!
With such a short bed the tailgate is in the wind shadow of the cabin anyway.
You increased the drag.
MG ZS EV 2022 it shows the temperature outside. Also when it goes below %10 it shows the remaining range. Am driving the UK version. This Truck looks good and here where it's stop,
Can you test the Ford F150 Lightning.
That consumption is crazy high. I would like to see a table with frontal area vs consumption.
Drag = Frontal Area * Drag Coefficient
@@moestreiYou neglected:
• density of fluid
• speed of the object relative to the fluid
@@aliendroneservices6621 Is air a fluid?
@@moestrei "Fluids are materials capable of flowing and easily changing shape. The most familiar natural fluid is water. But *_air is considered a fluid as well."_*
Ok next test with a canopy fitted please.
Closed is better as during driving an rotating air tube is been build behind the cabin. The consumption is compared to having a roof while without there is a lot of air disturbance. I have seen a science documentation that deals with that question some years ago.
and he tested it and there was no difference that could be measured.
@@richard--sthat's what he said, based on the shown number the closed tailgate has shown slightly better consumptions.
And to be clear also in the documentation I have seen it was not that by open or closing it feels like exchanging the car. But their tests have been a bit more extensive. Also using windchannels to identify what is going on.
@@Gnubbelhurz OK!
Could Tailgate be the Pickup version of RapidGate! What The Truck Man Shhiieettt! 😂
Driving with open tailgate is like driving with folded side mirrors: barely legal, unsafe and has no significant efficiency improvement. But, some people are going to do this anyway...
Your like me when i drive through innlandet i put on western music because thats basicaly norways Texas 😝
I guess that the cabin is making vortex. Thats why there is no difference here.
And maybe its the reason why Cybertruck has cover from the top of the cabin to the tail.
It should be tested with cybertruck !
"Aug 8, 2019 - The aerodynamic analysis shows that the drag force is *_19% higher at highway speeds with the tailgate removed..."_*
ye boi
Who wouldn't want to be in cleveage at night. Sorry I meant Kløfta
❤❤❤
Does tonneau cover affect efficiency?
Yes, it should improve consumption.
Yes, tonneau cover saves a lot of fuel
Use a tonneau cover for the truck bed.
That's how you do it, not opening the tailgate
What’s his name? The little cowboy in you? 😂
Brokeback
Skip straight to 5:30 - don't ask any questions.
Most pickup tailgates are easily removable - if you know the specific trick for your model - which would eliminate the problem of obscuring the license plate.
♥♥♥
How old is this?
If you charge on Tesla supercharge in Sweden. You can charge from 2,90kr in Gbg and around Sweden 3-4 kr. Ionity is very expensive and is always broken.
Tailgate down improper engineered pick up does definitely not improve Aerodynamics.
Oh dear. 😂
Tell SAIC to bring thing to the States. It's gonna put Toyota Tacoma on notice.
Ionity must be totally out of mind, 6,99 NOK per kWh equals to 2,87 €, and i hear always that electricity in Germany is expensive. Obviously Legacyauto is kodaking itself.
That's drop-in price. Most people have way lower prices via their brands.
And 6.99 NOK does *not* equal to 2.87 €. Your math is way off. It's about 0.6 €.
Bjorn barely legal Nyland! Did everyone get the cleavage joke? lol
I thought Barely Legal was your girlfriend's name! ;) Before you were married.
That is very cheeky !!
I love it !!
❤❤❤
