To the average person, a picture of Model Y probably looks like a sedan. Some of the larger markets have not responded well to model Y because it doesn't look like a traditional SUV. To constructively criticize Tesla, it may have been wise to simply call model Y a "crossover". It lacks the trapezoidal shape. I must admit that when I saw Model Y, my heart sank. My first boy reaction was that it is not an SUV! It needs a redesigned backside! I wrote a critical article but chose not to send it because I realized I was jumping on the gun and several others CleanTechnica authors had actually been in the Model Y.
A few days later I had actually changed my mind completely. Dr. Mad Max Holland's article on the model Y's size along with Paul Fosse's article on the third row helped. Below is a picture from Max showing the difference between model 3 and model Y.
The last week I have obsessively seen and read several reviews from people who got a test trip in the model Y. Everyone was fascinated by the new glass, which lacks a center post. In model 3, the glass is two glass sheets separated by a large horizontal column. The general consensus is that model Y feels much bigger inside than it looks from the outside. It was specially designed like that, Elon Musk put in a tweet.
In addition, the glass buys a couple of inches of ceiling height relative to the average cushioned and insulated metal roof. The Tesla Model Y ordering page says, "An expansive glass roof provides more headroom and UV protection."
Here you can see the second and third row seats fold down to create 66 cubic meters of storage space. For comparison, I have a RAV4 that has 72 cubic feet. (I'm planning to sell it soon as I give up with a transport-as-a-service vehicle). I love my RAV4 and hoped to get an electric version, but they stopped making them after a short trial. I am 6 & 4 "and can totally lie down when seats are folded, allowing camping and napping on epic roads. I expect I could do the same in model Y because it is based on unofficial reports , it could be 2 inches longer than RAV4.
I was hoping that Model Y would have the same space as my RAV4, and it looks pretty close, from the best I can tell, the sloping tail end is critical to aerodynamics. shines in that department, with a 0.23 drag coefficient compared to 0.31 of the Toyota RAV4. (The lower the number, the more efficient the vehicle is.)
I remember this week and my sister's Living room feels twice as large because the entire wall is glass. Houseguests are mesmerized by the views of this sustainable home. Watching TV is especially nice, but sometimes difficult to keep focused because your mind is wondering in the clouds.
Except trying to earn brownie points from my sister, I mention this effect because it is the same concept of model Y. The glass roof is so unique that it can make consumers forget about the trapezoidal shape they are commonly used in a crossover SUV segment. It will set a new precedent in the automatic world. They say everything is bigger in Texas. Well, here in Austin, thoughtful and intelligent design can give you that feeling without having to use so many resources.
To promote this discussion, let's look at another popular electric crossover SUV, the Hyundai Kona EV. It has a coefficient of 0.32 – remember that Model 3 has a coefficient drag of 0.23. The wife's length is 13.7 feet and the unofficial length of model Y is 15.4 feet.
It is shocking that the Hyundai Kona EV has a small cargo space of 45.8 cubic meters, while the Tesla Model Y has 66 cubic meters of cargo space.
Our YouTube friends on "Like Tesla" also have a great built-in model Y video that helps show the vehicle a little more – well, in the dark. (Also check their back scenes and video of the event.) "Like Tesla" is a great YouTube channel I recommend. I hope Kim can convince my sister to get a model Y. So hopefully in a few years when my sister needs me to remember, she can just send model Y to pick me up, since I've pretty much given up driving. 19659007]
Kia Niro (above) has a bit more of a regular SUV look. But it comes at a hard price. Niro has a poorer 0.30 drag coefficient and only 53 cubic meters of cargo space with the back seat down. Once again, the Tesla Model Y is far superior, with a drag coefficient of 0.23 and a load of 66 cubic feet.
So, model Y will have 13 cubic meters of storage space, yet much more aerodynamic. This video provides a nice breakdown of storage capacity with other rows up to Niro EV and compares its statistics with other popular EVs.
Then we have the Audi e-tron, with a drag coefficient of 0.28 and load space of only 57 cubic feet. Even at $ 72,000 + I can't find an electric crossover SUV with more cargo space than a model Y.
Kia Soul EV has the traditional SUV shape, but its drag coefficient is horrible at 0.35 and that cargo space is only 49.5 cubic feet. In addition, it is only 13.5 meters long. There is no laying on the back of this car, at least for me.
We can trust that Tesla will do the right thing, instead of the simple one. The simple thing is to make a small version of an SUV and keep its ineffective design because that's what people are used to. The right thing is to create a crossover that has the best combination of range, volume, safety features, autonomy and aerodynamic shape. Tesla could have made it a traditional boxy SUV to match consumer tastes, but it would have come at a price. Instead, Tesla chose function and sustainability over conventional form.
It's simple physics! It is designs that are based on first principles and not what everyone else does. You don't make an SUV like everyone else. Instead, you think in the most aerodynamic / safe form and then change that shape as little as possible to create a functional and pleasant passenger space. So to go beyond, get creative with other materials (glass) to offer even more ceiling height and a wonderful sense of expansiveness .
Hopefully, Tesla can change the traditional notion of what the form of SUVs should be . The shape is just a more sustainable design. This shape can be scaled up in the future as batteries become cheaper and denser. Of course, Model X is basically a larger version of Model Y (with deeper doors). This form will always be more sensible when it comes to physics.
It is worth a shot for Tesla to create a paradigm shift in view of what an SUV should look like. Nevertheless, I unofficially request a future model G, as in the Giant, to compete with the Chevy Suburban. It will be able to fly "like a G6" (it's a private jet). Such a vehicle will certainly be possible in the future. It can be financed from the yield of model Y. It can also be the basis for self-propelled shuttle buses. Hopefully, Model Y's superior form doesn't go anywhere. If physics has its meaning, it will not.
I'm sorry I can't give you more specific details about how important the decline to model Y is its drag coefficient. It was not for lack of effort. However, I know that a water droplet approximates the ideal shape of an aerodynamic car, and that is the likely cause of the sloping back of model Y and the whole of S.3.X.Y. alignment. This is something I think Tesla could have better explained in the presentation, but it is a bit clear when looking at S.3.X.Y. models at once. This basic form should probably be a timeless principle, just as the wheel is for transport and the arch is for architecture.
You can argue that Tesla should just do what everyone else does. However, I think what Tesla has done is the most accurate.
…… the other three. Autonomous cars will be drastically safer, more sustainable and have the most important functionality a vehicle can have. We must remember Tesla's long-term goals here, which is to develop self-propelled taxis, shuttle buses, buses and semi-trucks. Revenue from the sale of S.3.X.Y. Models will finance a future where most and businesses use self-propelled taxis, shuttle buses, buses and semi-trucks (in connection with other forms of public transport). Transportation as a service will be significantly more sustainable, safer and more convenient for our future cities. And that's S.3.X.Y. lineup that will perfect self-propelled technology so that most of us do not need to own cars in the future. Finally, we can save thousands of dollars every year by choosing not to own a car. Of course, sharing is more sustainable.
I think Tesla is incredibly wise to put self-propelled hardware into each model Y. The company does not know who will buy the self-propelled software at a later date. The extra revenue from software packages will be significant. However, in the next few years, it is most important to have as many Tesla cars as possible and collect data to train the self-driving software. Of all companies that work with self-propelled vehicles, Tesla probably has ~ 99% of the autonomous mileage driven. That management is growing every day.
Tesla could have made a slightly larger SUV, but then it would have fewer resources to put in self-propelled technology. It would probably not afford to put self-propelled hardware in any model year. It is my belief that almost every model year will eventually be upgraded to self-driving in one way or another. Some will probably be traded in and become self-driving taxis themselves. No other car dealership sells cars that have the ability to earn large amounts of revenue after they are already sold.
The creation of Model Y will attract most buyers possible while achieving the four factors (goals) listed above. Hopefully, other vehicle companies will notice the much improved aerodynamics of model Y and the whole of S.3.X.Y. presentation present. A drag coefficient of 0.23 or less can be the norm. Part of Tesla's importance is to make that norm desirable, as opposed to having it required by government regulation in any form or fashion.
Last week, I thought Tesla had to change model Y to make it look like other SUVs. This week, I hope our perception of what an SUV will look like will be permanently changed by the Tesla Model Y. In addition, the long length of the Tesla Model Y not only makes it more spacious, aerodynamic and efficient, but it also provides bigger crumple zones to keep us safe in accidents.
Tesla Model Y is considering what needs to be done to make transportation safe and sustainable, a major step forward in technology. I think it will be clearer over time. So be tuned.
As an addition, I would like to note the following: I try to read as many comments on CleanTechnica as possible. It became a full-time hobby many years ago. Some commentators feel that we have an unfair bias towards Tesla. I'd like to address this criticism. We are independent writers scattered all over the world, and almost all of us have day jobs. I write about what inspires me and what I think is most important. It wasn't long since I thought Tesla had made toys for the rich. It is the opposite of the truth, which I have come to learn, which you can read about here: Why Buy a Tesla is the best thing you can do for the environment .
