Aero and turbine wheel covers economy test. Tesla Model 3 SR+

Good morning guys, Matt, it's not in the manual here, so today I'm going to do a cheap

test

. I had to arrive quite late at night just for the traffic to calm down. I have had the new tires installed on the car, you can see them here. I've done 1258 kilometers and the

economy

is 131 watt hours per kilometer, so that's pretty good efficiency, so these tires haven't increased efficiency or decreased efficiency. The car is still super efficient. I've been pretty happy with the tires so far. These are more of a comfort tire than a performance tire, so I'm happy with them because I like them.

The steering is not as responsive as the sport pilot, but I'm going to do a separate review on these tires and go over the features and explain a few things, so I'll leave that separately, but so far I've been pretty happy with them, so What I'm going to do is reset that, reset that trip, so I might rename it, we'll just call it economic

test

, okay, it's not e-primus anymore, but we'll click here to go down and reset the trip. economical, so that's it. that resets there so we're at zero what we're going to do is drive about 25 kilometers and come back and I've got the Aero

wheel

covers

on right now and then what we're going to do is this

economy

test.

We'll try two things: we'll see how these tires perform stock with the

aero

caps, and then we'll put the induction

wheel

covers

on and see what kind of difference they make in economy, if anything. We've reset that we're going to drive on the M2 motorway, it's reasonably flat, it's not a windy day at all, so it will be a reasonably fair test, now it won't be a super scientific test, but you know. we're doing it all at the same time, so it's going to be reasonably fair and, you know, you really only want to do these tests under normal driving conditions, so it's going to be pretty normal driving conditions.

I just wanted to be able to maintain a reasonably constant speed and that was the main thing and not have wet roads or really windy conditions, so yeah, it's looking pretty good, so let's get out and start driving, a little busier than I thought, but um. my battery is at 34 degrees, ambient temperature is 24 degrees, rear motors at 41 degrees, so everything is pretty stable, so I know that's not going to influence the economy. Simply set the speed to the current speed limit, which is 100 kilometers per hour. So most of this test will be done at 100 kilometers per hour and you should be able to keep that speed fairly constant throughout this test.

Let's do an automatic lane change and see how you pass these slow cars. This would be a good opportunity to test autopilot. If there is any improvement with this latest update 2023.2.10, we will see how we go down the usual path, you overtook and the card accelerated. This is where the automatic lane change, you can see it here, um, disengaged the steering. so it's a bad time of day with the uh with the Twilight here it goes, it's doing the automatic lane change now so yeah, the automatic lane change isn't much better, it's having trouble with these roads here where I don't know if you can see I notice it when the camera is getting the contrast right or not, but they repair the cracks in the road with this type of flexible rubber sealant and at night or if light comes in at a certain angle, those lines light up and I think the cars with Navigation safety systems with cameras really have a hard time seeing the lines and with automatic lane change you will only change over broken lines, so if there is a darker line or these repaired sections here that light up, it thinks the line it's not broken. and it's not going to cross an unbroken line and I think that's where sometimes the automatic lane change doesn't work, it's because of the bad markings on the road, so I think we can see it fine, but I think the cameras really struggle, you can see here now the carburetor wobbles a little bit in these sections.

It is very difficult for the car to determine which is the lane marking and which is a repaired section of road. It's a great sunset here today. I don't think it will do much for the cameras, we'll see how I have my GoPro hero 10 and my insta 360 here today, different angles, yeah, it's very nice to drive into the sunset, you can hear those little repairs. The markings on the road are also quite noisy, so it's not these tires. You can see that this road is pretty horrible and in the wet and at night it's almost impossible for the car to try to see the lane markings here on this road, so I think.

We will have to greatly improve our roads if we want to have safer cars with their guidance systems. I am quite happy with the noise level of these tires compared to the pilot sports ones. They are possibly a little bit louder, but Well, at high speed, but at low speed, I think they are quieter and actually a little more comfortable, so I don't think the sidewalls are as stiff on these tires as they are on the sporty pilot, so the noise levels here aren't too bad. I'll probably do a separate noise test. I didn't bring the sound level meter today and I'm not really prepared for that, so today is just the economic test, so just passing the exit I was planning to take towards Seven Hills, but I'm not even at 20 kilometers yet, I might push it to the 25K or about 25 km for us to do a 50 kilometer round trip, which makes it a little fairer for the economic test and, yes, I think 50 was a pretty good thing, is where the application of energy looks back at the fifth of the last 50 kilometers.

I think that's a pretty good distance to do a cheap test, okay? I think we'll just take this exit here, 23 kilometers and three kilowatt hours, so here at the halfway point we have 124 watt hours per kilometer, so we're here at the Sunnyholt Road exit, it's going to be pretty close. to the amount of kilometers I want to do, what we could do is go down further here and then turn around, okay, turn around for the return trip, now we get back on the motorway, this is the M7 motorway, it eventually becomes on the M2 motorway and this.

It takes you straight into the city if you want and if you come back that way it takes you to Canberra if you continue, so it's a pretty big arterial road through Sydney, so yeah, 25km return, it worked fine once I went. I got up, turned around, and we got back on the highway, so we were doing 125 watt hours per kilometer, just accelerating toward the highway. I've seen it increase to 130 watt hours per kilometer, so we'll start the autopilot again and set it up. to 100 and just returning to the starting point to navigate on autopilot can be quite annoying, sometimes you can see here, it tells me to change lanes to follow the root, but it is not necessary, no, it is not necessary to enter that lane . no exit, no merging, no nothing, but it tells me to cross, so if that ever bothers you, you can turn off autopilot navigation there and it goes back to standard autopilot, so you can click again if you want . navigating back on autopilot is pretty easy to do, if the suggested lane changes really bother you based on speed, you can see this one tells me to follow the root and get into that lane again, so it's not a suggestion lane chain based on speed, so I'm going to turn it off because it bothers me and use the standard autopilot, which is pretty good anyway.

Well, we have finished the second leg of the first half of the trip, so we have 49 kilometers, we used six. kilowatt hours now it says 122 watt hours per kilometer, but when I took the exit and I was regenerating, when I took the exit it went from 126 watt hours per kilometer to 120 and now it's back up to 122. Let's take it. As you know what it was before taking the start and that it was 126 watt hours per kilometer, now I am going to put the induction wheel covers and do that test again, repeat it again and see how we go with the induction wheel covers. induction.

Ok now I have the induction wheel covers installed we will reset the economical test and repeat so my main concern with the induction wheel covers I bought was just a big ridge on the ends around the outside edge of the wheel . I'm a little worried about how

aero

dynamic it is and also what you don't know is the kind of fan shape on the induction wheel covers, you know, they have the angles and things there, they're going to create a lot more turbulence, eh, that's the strange unknown point, so what are we looking at? 134 watt hours per kilometer, it was actually 140.44 right before we took off there and we did a big long regen there, so, yeah, it looks like it could.

There has been a little more consumption, a little more consumptive, but it is not a big difference to get back on the highway for the last leg of the trip. Once we get to the end, I'll park the car and give you a briefing on how. everything went well, so we are at the start, at the end of the second stage, so the economy is 133 watt hours per kilometer, so a little more. I was at 126 watt hours per kilometer with the standard Aero wheel covers, so I'll have a little more. Look at it in a little more detail.

We'll look at it at Tesla Phi and I'll compare the two rides and just look at the overall economics. Alright guys, we're here at Tesla. 5. So this is a website that records data about my car. I give it permission to take trip data from my car and a couple of other small data points. I don't let him control my car. You have a voice and a vote. which when you set it up initially it records my trips and this is pretty good to look back on trips to different places and see what the differences were on these trips and for me to make these videos I think it's pretty good to go back and take a look at these trips and see the data if something happened on the trip and I wasn't taking note of things, so it's pretty cool, so we can see here that we have both, both. round trips, so this one above was with the Aero wheel caps, the standard ones from Tesla and this second one here was with the

turbine

wheel caps that I bought from tesseries, so I made my previous video, you see, I made a review about that.

And uh, we've installed it, although we showed you how to put those wheel covers on, so looking here I think it was a reasonably fair test, it was the same amount of time, the kilometers are slightly different between the two and that was purely uh, At one of the change points I had to take a small detour to make a U-turn from the other, so there is a kilometer difference for a little over a kilometer difference, not a big deal and, in fact, it's even higher if you're giving the Aero wheel caps have a minuscule disadvantage, but overall the efficiency was fantastic with the Aero wheel caps 123 watt hours per kilometer and you can see here, I mean, it was a hundred kilometer hour zone, but had an average speed of 83 kilometers per hour.

So what that does is it takes into account the extra slower speeds that you were doing at each end, so, you know, you're getting a little bit of that slower speed there, but what was the whole point of this test. Compare the Aero hubcaps to the

turbine

hubcaps, so most of it was at higher speeds and 100 kilometers per hour in the air along the highway and you can see here 6.05 kilowatt hours used for the Aero 123 hubcaps watt hours per kilometer as opposed to the 6.43 kilowatt hours and 134 watt hours per kilometer of turbine wheel covers. Very very close, they are not a dramatic difference, so I wouldn't worry too much about the efficiency of the car with these turbine wheel covers.

I was initially concerned about the hard edges on the outer diameter of the wheel cover. Oh yeah, just a little worried because it wasn't a nice smooth curved surface, but it doesn't seem to have made much difference here, but you can. See, there is a difference and on a trip much longer than you think, 48 kilometers that will accumulate. I wouldn't be too worried about leaving them on for a long trip, you know, with a long trip, as long as you have enough. enough capacity or range in your battery to go from one fast charger to the next with a margin of safety greater than 15, you know, 20 percent, so yeah, that's pretty good and that was the main point of this, obviously , these are ideal conditions.

Also, you're not going to get this in the middle of winter somewhere in Europe or North America, you know, ideal temperatures, the battery was nice and warm, everything was stabilized, the air conditioning, the HVAC didn't have to work too hard and um , you know, look at the outside temperatures 23.4 22.8 uh ideal, ideal, not much wind, such perfect conditions. I couldn't have asked for better conditions to run an efficiency test, so there's not much outside influence on that and it's very similar. The results with the two trips were quitegood, pretty successful, so I guess I've shown here that you don't need to worry too much because when you put these accessories in, it won't affect your economy dramatically, so I hope you have something.

In this video it really shows how efficient these cars are and you can see here with the Aero wheel covers. What I also wanted to do was test the new Michelin e-primacy tires that I generally have in my economy. The 26,000 kilometers or whatever the car has done was now 144 watt hours per kilometer before installing the Michelin e-primacy tires and that has been decreasing so overall these tires are actually more efficient than pneumatic tires. Original Michelin Pilot Sport Teslas that were installed on the car and my driving style has stayed the same and I think that's pretty good, you know, it's headed in the right direction anyway, so those tires seem to be on point. live up to the hype and the promises of the features and be efficient.

They're a comfortable tire, though, um, yeah. Comfort over performance, but me. I've been very happy with those tires so this was an efficiency test for them as well, so I'll do a separate review on the Michelin e-primacy tires and include this and possibly do another separate efficiency test for those as well. Just to verify this, but yeah guys, that's it, I hope I get something out of this and I'll see you in the next video.
