welcome to another test video from nextmove
today we are testing the Aero Wheels of the Tesla Model 3
actually they are just wheel caps
We want to find out? Is there any effect and how big is it?
We have three Tesla Model 3 in this test.
We want to find out minimal differences.
What is the best time to drive smoothly on the highway?
Sunday morning at 7 am!
We want to drive more than 200 kilometers. One addiotnal car will accompany the test for 
reference puropose
to later eliminate potential fluctuations due to wind, battery temperatures in the calculations.
So we take it seriously todaywith the test.
But let's take a look at the wheels first.
First let's jump back to the year 2012.
Tesla introduced this Aerowheels for the Model S
the goal was the same: to increase range
A completely closed alloy wheel with
some ventilation opening for braking and
abraison.
Due to ugliness they were kicked out of the configurator shortyl after.
Meanwhile the trend goes clearly into this direction at many manufacturers of EVs.
If you see an EV, take a look at the wheels.
For example the Tesla Model 3.
The solution is a wheel cap that you can take off swiftly.
There it is.
Below is an alloy wheel rim - of course a bit dirty now.
And it does not look that good right now.
What can you do? First wash the car.
Second you can use covers in grey or black. They cost 10 to 20 € for one set.
So you can put it here
and cover the bolts.
It is quite tight. You cant remove them easily.
the set comes with a small tweezer.
So if you want to remove them just use the tweezer
Works with no problems. And in the middle you have to cover the hole.
You have two options to solve that. The cheap solution for aboutu 10 - 15 Euro
but make sure you find covers that fit.
The original Tesla Model S covers for the 19 inch wheel fit as well.
Or you buy the covers for the Model 3 at Tesla. And voila: you have a nice looking wheel.
We are checking the tyre pressure.
All three cars are set to 3.0 bar.
Let'a align on all values: speed  on the Autobahn 150 kph according to traffic, Autopilot is allowed
but not for acceleration and braking.
Because we can do that more efficient than the Autopilot.
If there are speed limits we go to Neutral and roll.
We drive in chill mode, heating is switched off
On the last traffic light before the motorway, we reset the trip meter to 0.
The first acceleration on the feeder will be taken into account so to say.
First stop. We have taken off the aerowheels from two cars now.
Next round we test the consumption without aerowheels.
and the third car is for reference in case we have differences between the rounds.
so we can count out these differences later when we do the math.
We our now on the last round and I am really curious about the results.
So what is the bottom line of the test.
We had three Model 3 on the line. All Long Range
Two RWD an one AWD,
one of the RWD had a special suspension - a bit lower than normal. But that was not the point in this test.
We concentrated on the difference with and without Aerowheels.
To increase the data basis we send three cars into the test.
We drove 3 rounds around Leipzig on our hometrack - 94 km each.
Speed 150 kph if traffic allows- for most parts that was possible.
The highway was almost empty because it was Sunday morning
All three cars were on wheels 18 inches
on summer tires and in the
In the third round we took of the aerowheels on two of the
three cars
The third car drove again with aerowheels for reference puroposes. We drove 3 rounds because we were concerned
that between round one and two yet
a difference in the consumption would occur
due differences in the battery temperature.
So we wanted to rule that out.
What were the results?
The values in round one and two were atually very close to each other
So no noticably effect to warming of the  battery and thus same consumption.
So we included the values from the first round into the test as well.
To have a larger basis we averaged the results from round 1 and 2.
Furthermore we corrected the distances. All cars travelled the same distance but
showed different trip distances on the board computer.
We saw differences of up to one
kilometer
This is most likely due to the tread depth of the car tyre
One car was new, with new tyres
The others had already more than 10,000 km.
so then we anaylzed first our 
reference vehicle
and checked the values ​​between round one
two and three
So we wanted to check wind effects, side winds,
Although we drive a round that in total the wind is the same,
also differences can occure.
So we had a deviation
between the mean value of round 1 & 2
against round 3 of 0.7 Wh per km, So 0,07 kWh/100km
So very little and it shows how perfect the test conditions were.
And the other 2 cars had 5 and 7 Wh per km more than in the first tweo rounds.
So that means 3% more range
on a full battery charge on the Autobahn that means 8 kilometers more range at 150 kph with Teska Aero Wheel caps.
compared with the 18 inch wheel without the caps.
Our conclusion: If you don't like the Aerowheels, you can easily leave them at home
and use the solution from the beginning of the video.
But on long distances you could consider using them.
to pick up these 3 percent.
on the other hand we are talking about
electric cars we're talking about
use of resources and we are talking about
efficiency and three percent are three percent.
And if the OEM would increase the battery by three percent,
to reach the same range , than that would be more expensive
than a set of plastic caps for the wheels.
In that sense this solution is attractive - I am a friend of efficient vehicles and my
personal choice would also be a Model 3
with the 18-inch Aerowheels and the caps.
I hope it was an exciting test for you. We tried hard to measure the differences
as best as possible. And I think we succeded in doing so.
