The noise is coming from the bugs... screaming.

[@mitchellbarnow1709]

Great video, Brian! I’m really surprised how close your results were, even with all of those variables. Thank you so much for doing the boring work, so that we don’t have to.

[@i1Tesla]

I was too but I would give it a 2-3 % as I probably drove smoother with the rack on. Just to be fair, but that is still good

[@HansMilling]

Great video, nice to see you test and review all this stuff. I can’t rename my trips, I guess I am an update behind.

[@JL-ij2xc]

Yeah, wind noise. I had a Taurus wagon years ago and I ended up having to pull the roof racks off because at certain speeds it would cause a drumming noise. As far as which one is causing the noise, just take the front rack off and drive the car and then come back and put the front one on and take the back one off and drive the car. That should let you know. The racks are an airfoil. Maybe the roof rack engineers need to do a little bit of tweaking to the geometry of the airfoil. Keep up the good programing and I really enjoy it. Have a good day and stay safe. Cheers, John L. in Fairlawn Virginia USA

[@luckydog7776]

I’ve found similar results with my Model 3 roof rack over the past several months. Relatively small increase in wattage with roof rack alone. Thanks for the video.

[@ctuna2011]

What about with something on it?

[@luckydog7776]

Charles Jutkins there is for sure negative efficiency impact with putting something on the roof rack (e.g. ski box or kayak) and there are a number of tests online that give approx loss figures. But of course this is all expected regardless of the type of vehicle. With nothing on the roof rack, there is little impact.

[@ctuna2011]

Can you quantify them

[@kurtpenner2362]

Hey Brian, thanks for this vid. I think I asked you some time ago to do this test.

[@MegaBoidin]

A good one Brian, going to get them when I get my model Y 👍👍👍✋🇧🇪🇧🇪

[@tilted8]

Really appreciate this test! You are doing the test in the best way you can and it is scientific because you’re documenting your work and reporting results and commenting on your confidence level of the test itself.

[@ecdriver6595]

Good video Brian!

[@sludged08]

If you have wind noise with your roof rack, wrap them with cord, I wrapped bungee cord on my front rack and it eliminated all the wind noise

[@Luke_Starkenburg]

Hi Brian, do you know why Tesla isn’t letting my buy a Model Y with the referral code? Do you know when they will make the Y part of the referral program?

[@erickessler6094]

Brian, Great video! I'll look to see if you did a noise reduction Update. :-) Cheers, Eric

[@loljz]

Where did you get those i1Tesla headrest pillows for the back? I really like them wondering if I can get some for myself.

[@HalBran]

Regarding wind noise, would the aftermarket spoilers that fit on the rack help?

[@aytchroberts5850]

[@MarkHamric]

Awesome video! Will you please put a roof cargo box on the rack and test the kw/h difference?

[@HuntAndFishExchange]

Nice video, but can you do one with the surfboard or SUP strapped on top?

[@omsi-fanmark]

Nice to see that the Roof Rack itself isn't such an energy drain (looks OK as well), but that will change drastically when you actually put something on top of them, a cargo box for example.

[@jim52356]

would love to see a test with a ski box or something on top

[@FamilyFirstJ]

As expected...great video

[@cree8k]

How about putting a luggage carrier on the rack and test it!

[@BrianMurrays]

Put it on backwards as well. It’s supposed to be more aerodynamic that way. electrek.co/2020/03/24/tesla-model-3-roof-rack-box-range-efficiency/

@@evanharris5088 Smooth laminar flow and minimizing turbulence on the tail end. The teardrop pointy end backwards. Cool stuff great catch.

[@coreycummings8662]

Brian Murray the Y roof rack is different than the 3 rack and is more aerodynamic

[@pilot1226]

Great video. Thanks for your research 🤙🏻

[@i1Tesla]

My pleasure!

[@pilot1226]

Any thoughts on durability with off and on a bunch of times... or is this something that should be installed and just left on there?

[@ctuna2011]

At one percent I would just leave it once setup . It is glass roof you know.

[@miquelbiggs5721]

Glass roof looks dope

[@glenm5679]

Another great video. Thank you! I can't remember did you get the roof tinted? If not, does your head get hot when it's so sunny out?

[@i1Tesla]

I did not yet. I do feel a little heat

[@stephenreinhart7393]

Loved the test. Can you test it with skis or snowboard.

[@frcgfd107]

I honestly thought it would be around 310, I am surprised that it was so low, nice going Tesla!

[@ctuna2011]

I would like to see and efficiency test with some long surfboards or sailboards on the tesla. I saw a 3 test with a rocketpod and it was pretty good. I saw one test with the seasucker's rack and it like a 30 percent hit.

[@GadgetBoyea]

I find autopilot works better in the interstate left lane. The on ramps mess with it if in the right lane.

[@i1Tesla]

Very true

[@IanNelson]

They don't look flat so my roof box won't fit?

[@MrNURSE]

How's the view?

[@JZainbear]

You should get a tri-pod and drone and do more shots of the Model Y as you come and go. Your a good looking guy, but till mine comes I'd rather see the sweet ride :) aka Gray Babe.

[@bobbyjayy_]

Yo i commented one of your other recent videos, I wanted to get your opinion on the evpremiumcustoms headrest?

[@i1Tesla]

I think they are great. They doin't fit me because of how tall I am but he is making me a new one so I can use it upside down

[@justinfowler2857]

How does that glass roof do with sun and glare in the summer? I've seen people sitting in them and they are shaded, but would like some real world comparison.

[@ManchesterUtdFan]

Incredibly minimal. Tesla did a fantastic job. My kids sit back there and not once have complained.

[@garyclark6747]

Remove one of the two and check for noise. Then trouble shoot from there. At that price they should be silent. Do you have a db meter app or device? How easy is it to add and remove? Putting them on only when needed would be ideal. Can they stow under in back?

[@i1Tesla]

Great idea I will try that. I don't have a db reader but I could use an app. They are very easy to remove and put on. Little big to store in the car though

[@garyclark6747]

i1Tesla that’s a shame about storage because you have such a beautiful panoramic glass roof. Was that a ceramic tint you put on to reduce heat?

[@DirtyTesla]

lmao pretty much any video I make if I'm in the left lane for 1 second or more I get complaints :P

[@GarretL757]

take one off and see if the noise is better or worse, rinse and repeat

[@i1Tesla]

Tony from www.1975creations.com made them for me

[@techyjames1945]

Curious with my M3 I noticed the range was always lower than EPA range. Are you seeing same with the Y?

[@i1Tesla]

You are never going to get EPA range if you drive like everyone else or with climate control on. That being said the Y is very good

[@domg7359]

Your range will be higher than EPA in the city, lower on highway. It's just the way EPA does testing. The average speed during EPA test cycle is only 48mph, and they max out at a speed of 60mph. Most people drive faster than the EPA max on the highway. The EPA should really change the test, given that many people look at the range number with the highways in mind for a long trip.

[@drdrew3]

Techy James You can get either higher or lower than the EPA rating depending upon how efficiently you drive. In that respect it’s the same as an ICEV

[@techyjames1945]

Dom G I think totally agree. Most highways have a 70 MPH speed limit so expecting a max speed 60 MPH is unrealistic.

[@tonyc6996]

Real test is with stuff ON the roof rack. Local club member added a rack and skis to their 3 for weekend trips and with the cold and added drag couldn't get over 150 miles. Due to lack of quick charging between their house and the ski slopes they had to abandon the Tesla and use a different vehicle because they couldn't go round trip

[@ctuna2011]

Real World numbers are what we need thanks. However how much of this comes from Cold and how much from drag?

[@tonyc6996]

@@ctuna2011 they used to make the trip with the equipment in the car. After adding the roof rack they could no longer make it round trip.

[@bhags777]

Is that with the 21’s or 19’s? Also how’s the heat and glare with that roof?

[@i1Tesla]

21's. I do feel the heat on my head but I dont' have hair

[@drdrew3]

bhags777 There’s a layer of super heated air just below that giant glass roof but the Y has so much headroom that most people aren’t tall enough to feel it. And there’s no glare inside car because the roof is heavily tinted (just don’t look up if the sun is directly overhead).

[@Hamza-xc9kb]

Is Tesla’s glass roof stronger than a normal car roof?

[@tonyc6996]

The rack mounts to metal mounting points under the glass

[@davidholdman5518]

4% impact consumption on a total tank (battery) for me.

[@nbookie]

At least it will keep your roof on when it peels off

[@jasonparry7173]

the front one has more bugs... maybe because the front one has hit all the bugs they don’t make it to the back one 🤔

[@irfansafi1714]

Yup

[@DDrawer66]

A roof rack fairing would probably eliminate the whistle. Less efficiency though.

[@constructioneerful]

Maybe test with bikes on the rack?

[@mr.blahblah4731]

Probably get more of a difference if you put luggage up there.

[@b9506]

Real question is with something on the rack, for example with a roof box

[@philoso377]

One thing EV out standing is weight nearly 2x of ICE counterpart. What is the point? Heavier vehicle waste more energy stop-go cycling. For roof rack test and like kind tests - can we count record the number of stop-go cycles per each test necessary support a judgement call when two results are marching one another.

[@drdrew3]

YK Chan You are either bad at math or prone to extreme exaggeration. The Model Y weighs 4400 pounds and its closest sized Mercedes GLC is 3000 pounds. How do you figure the Tesla weighs “twice as much”? Bad guess

[@philoso377]

Andrew Leavitt You’ve got me this time.I hope I didn’t lost you. We have a heavy EV placed in two test conditions, w/wo roof rack. Test1 - wo rack but stop-go cycle is more. Test2 - w/rack but stop-go is less. Frequent stop-go cycles can build up energy loss enough to bias test1 result.

Did you see anyone else with me in the car. Or did I stop anywhere and talk to anyone. This is the problem with people right now. Yes it is bad out there but if you take the precautions you should be safe. I don't see any issue with driving around by yourself. Get out of your house arrest and take a drive.

[@mr.blahblah4731]

Hey Brian, thanks for the reply, big fan! Just thought it was funny you saying other people should be home because the lock down was for another week yet you were out too. And if you think about it KZbinrs are a mental essential worker, keeping people entertained or informed in this time. Keep up the good work. But at the same time, this will not be over until there is a vaccine or anti viral medication for this specific virus.Let alone if it mutates on an annual basis like the flu. We really do not know how many people have the virus as they only test people with symptoms. With most viruses you shed the infection before you have symptoms. So saying we need to get back out there is misinformation at the same time. Love the channel but we are far from this being over.

[@Robo10q]

Why do we all treat the speed limit like it is a suggestion?

[@drdrew3]

Rob Ostry Because traveling modestly over the speed limit is the flow of traffic and the limit is not strictly enforced. Ask a cop - they speed too when off duty

[@MrRichBenn]

I was a black belt statistician before retiring. With a single data point, you cannot get statistical significance. Likely one could easily get +/- 5% differences doing the same run 10 times, as one cannot control the lurking variables. Wind, traffic, tire resistance, road resistance and many other variables may change more than the rack affects the efficiency. If that holds, then it’s a good thing. Personally, the noise would bother me more.

Im a model 3 owner, but the roof rack is shit. Try to mount two bikes on it. They will stay in V shape because if the rack curve. Its so stupid. And roof box can break because of the curve. Tesla went with design and vindresistance instead of practicabillity
