The following is speculation based on the author’s experience, the known Model 3 feature set, and Tesla’s plans and recent statements.

Summary



The Model 3 reportedly contains Autopilot hardware dubbed “v2.5“

News outlets have yet to fully explore the meaning and purpose

Tesla isn’t providing a full explanation because they don’t want to tip their hand and they don’t need you to reserve a Model 3 — yet





Welcome to anti-sell and production-hell!



Screen-Shot-2017-08-15-at-9.26.37-AM.png


In a highly anticipated but somewhat awkward Model 3 delivery event, Elon Musk, ever the promoter, showed just one positive video of the car: the Model 3 being tested for side-impact where it effectively bounced off the testing device while one of the safest cars in the world, the Volvo S60, wrapped around it like a burrito.

Then he welcomed his fellow employees to production hell, showed a single slide that highlighted a handful of Model 3 specs, said nothing about the interior or any other features, and exited the stage faster than Jack Black hitting an empty mosh pit.

Don’t be fooled, this was the anti-sell.

Musk has been terrified of the Osborne effect since the original Model 3 unveiling, often publicly lamenting that people are mistaking the “3” for third generation and then taking that to mean it contains newer/better technology than S/X.

Note:  It actually does have newer/better/mind-blowing technology, but not in the way most people were thinking. The technology in question will be the subject of this post.

In fact, so pervasive is Tesla’s concern for the Osborne effect that they still anti-sell the Model 3 on it’s own webpage. Scroll half-way down and they’ll happily tell you all the ways the Model S is superior. Don’t reserve a Model 3; buy a Model S today!

Despite this concerted anti-sell and after only two 30 minute presentations and a handful of tweets, the Model 3 reservation count exceeds 455,000, more than the entire 2016 worldwide sales of the BMW 3 series.

Oops.

OK, great. So Tesla fooled 450,000 people into thinking they were buying tickets to a rock concert. They’re all just going to cancel anyway. What’s Model 3’s big secret?

Let’s walk through this mystery, step-by-step.

The Great Autopilot Head-Fake

Reports have said that the Model 3 has, what some are calling, Autopilot HW 2.5.

Here’s how Tesla responded to this report:

“The internal name HW 2.5 is an overstatement, and instead it should be called something more like HW 2.1. This hardware set has some added computing and wiring redundancy, which very slightly improves reliability, but it does not have an additional Pascal GPU.”

(The part in bold is key and will make sense by the end of this article.)

Still, HW 2.5 is being interpreted to mean that Tesla has already obsoleted the autopilot hardware found in the S and X and/or realized it’s not sufficient for full self-driving.

For example, the Verge wrote:



The updated onboard computer, dubbed “HW 2.5,” would seem to contradict the previous vow by Tesla CEO Elon Musk that all vehicles released since October 2016 would have the hardware necessary to achieve “full self-driving capabilities.

On Twitter, some of Tesla’s biggest fans have reached similar conclusions:

Screen-Shot-2017-08-15-at-9.27.37-AM.png
Are they right?  Did Tesla just declare AP hardware v2.0 incapable of full self-driving?

Well, as always, there’s another side to the story.  And — oh what a side it is.

First, let’s recall Tesla’s public plans.

Tesla’s Future Ride Sharing Network

In the second installment of his Master Plan, Musk outlined the future Tesla Ride Sharing Network as follows:

When true self-driving is approved by regulators, it will mean that you will be able to summon your Tesla from pretty much anywhere. Once it picks you up, you will be able to sleep, read or do anything else enroute to your destination.



You will also be able to add your car to the Tesla shared fleet just by tapping a button on the Tesla phone app and have it generate income for you while you’re at work or on vacation, significantly offsetting and at times potentially exceeding the monthly loan or lease cost.

Now let’s peel the layers of the HW 2.5 mystery.



There Can Be Only One

Screen-Shot-2017-08-15-at-9.28.39-AM.png


The Model 3, as it turns out, is Tesla’s Highlander.  

It’s the only car in Tesla’s current lineup capable of someday joining its ride sharing network. The S and X, despite appearing to share the same autopilot hardware, will not make it in current form, nor do they even make sense as robotaxis, given this imminent and cheaper alternative.

Aha! So everyone was right!

Let’s note the important distinction that everyone seems to be missing:  

Full self driving does not necessarily equate to ride sharing



Tesla is not saying that the S/X hardware can’t achieve full self-driving.  

And yet they’re not explaining the Model 3’s distinctive features because they’re already drowning in reservations and would rather you buy an S or an X.



But they left too many clues.

The Model 3 brings forward two very important innovations, one interior, one exterior. And, HW 2.5 is what’s needed to tie them together.

About That Model 3 Interior

The Model 3’s interior is certainly striking, if only for its minimalism. A quick comparison with two of its competitors.

Screen-Shot-2017-08-15-at-9.29.46-AM.png

From this, we can surmise that the Model 3 interior serves three purposes simultaneously.



It’s strikingly unique and unapologetically futuristic

It’s easier to manufacture (fewer parts)

It’s built for autonomous ride sharing



Yes, that last one. The Model 3 is built from the ground up to be the first candidate in Tesla’s future ride sharing network and the interior is the first piece of the puzzle.

The unique 15-inch screen is a hugely important feature.

Save for the window actuators (which are required) there are no other physical controls.

No radio.

No trunk latch.

No glove box handle.

No fiddly heating/air-conditioning vents.

Software Controls Go to the Next Level and Beyond

Who cares?  Tesla’s just cheap, right?

Not just cheap…  

Not having physical controls means everything in the Model 3 is software controlled. This means everything is configurable and remembered.  Everything. And more importantly, it’s remembered per person.

This also makes the main display the access point in order to do things like open the trunk or the glove box, or, in general, to operate anything.

Access to configurable touch screen controls can be either prevented or granted.

What are the first two concerns people mention when asked if they’d hypothetically share their car with others in a ride-sharing network?



 What if I leave something valuable in the car?

 What if someone pukes/destroys my interior?



As just illustrated, Tesla addressed the first issue through 100% software controls. Permissions for anything can be granted to the owner, but restricted from other parties.  



The glove box now acts as a safe that you don’t need to remember to lock.

The front and rear trunks are inaccessible without permission.  

Nothing proprietary or personal can be accessed from the main display



This has never been done before in the history of automotive.  And we’re only one third of the way through the mystery.

What about the second issue?

Monitoring the Interior

At CES 207 nVidia announced, among other things, AI Co-Pilot.  

They listed its features as facial recognition, head position and gaze tracking, natural language processing, voice speech capabilities, augmented lip reading, external environmental awareness.

nvidia_CES.jpg


As one would guess, it features a camera to keep an eye on the driver and interior cabin.  

The what?  What was that second one?

The interior cabin.  It monitors the interior cabin.

This would address the second piece of the ride-sharing interior puzzle: what if someone damages the interior?

And, in pouring over a video of the Model 3, someone noticed this.

Screen-Shot-2017-08-15-at-9.36.46-AM.png


An internal camera.

So, Tesla is not only using nVidia’s Drive PX2 board for autopilot, but they now appear to be using something very similar to its Co-Pilot technology to monitor the interior.

Let’s restate that for clarity — the Model 3 has a camera that can monitor the interior cabin in the event a third party damages something.

(Interior cameras will undoubtedly be standard in future robotaxi’s. And, yes, the car will likely not operate if the camera view is blocked. So keep your masking tape and magic markers at home.)

Also note that such a camera, not present on the S/X, would require computing power and new wiring to the Drive PX2/Co-Pilot board. Let’s recall Tesla’s statement to Electrek:

This hardware set has some added computing and wiring redundancy, which very slightly improves reliability, but it does not have an additional Pascal GPU.”

Are we getting it?  Tesla needed new hardware to address two of the biggest concerns in sharing one’s vehicle with a third party: restricting access to valuables and features, and monitoring the interior.  

But all of this still doesn’t work without one more innovation.

The Final Piece of the Ride-Sharing Puzzle

Screen-Shot-2017-08-15-at-9.38.28-AM.png
First we inserted keys.  

Then we inserted key fobs.

Now we have wireless key fobs that we keep in our pockets and can start the car with the push of a button.

Yet, none of these interactions are sufficient for a future ride sharing environment.  

You can’t lend your key fob to everyone who would ride in your car.  But, that’s OK.  It’s about to become obsolete.

The Backup Entry Option

As Model 3 videos began to surface it was quickly discovered that Tesla is replacing the key fob with an NFC key card. Entry via key card involves swiping it against the B-pillar, and then placing it in the cup holder.

tesla-model-3-keycard-packet-cupholder.jpg
While interesting, and simultaneously futuristic and (seemingly) a step backward, this is a red herring.

The key card is the secondary form of entry, and it’s purpose is to obsolete the key fob, not replace it. There’s something much more important in play.

The REAL Entry Option

Screen-Shot-2017-08-15-at-9.42.46-AM.png
The main form of entry to the Model 3 is actually your cell phone.

With the Tesla app and an Internet connection, one can press a button and lock/unlock the doors from anywhere in the world. Both the S and X also work this way.

Wait. What if you don’t have an Internet connection?  

And how is unlocking your phone, launching an app, waiting for it to load, and pressing a button possibly better than a key fob in your pocket??

Almost there.

Enter The Magic Protocol

As we know, everything’s better with Bluetooth. And so is ride-sharing.

Starting with the Model 3, Tesla’s mobile app will also run a persistent background service that uses Bluetooth LE to directly connect to the vehicle.

Bluetooth LE is an advertising/scanning-based approach that one can use to securely transmit encrypted public/private keys and data. It does not require explicit pairing like traditional Bluetooth.

In other words, with your phone in your pocket, the car will not only unlock as you approach but also know who you are and instantly configure itself with your preferences, privileges, and restrictions.

And that my friends is the final piece of the puzzle.



Tesla’s Entire Plan Revealed

Let’s recap.  Tesla needed new hardware to enable new features, not to change self-driving performance.

As such, Tesla is about to deliver, right under everyone’s noses:



Autopilot hardware it believes will be capable of full autonomy.

A 100% software-controlled vehicle that’s accessed identically by either its owner or a random person, and is fully customizable for each.

A camera to monitor the interior.

Vehicle entry with a mobile phone.



Autopilot hardware. A fully software controlled vehicle. An interior camera. Entry via a cell phone.

Autopilot hardware. A fully software controlled vehicle. An interior camera. Entry via a cell phone.

Are we getting it yet?

The Model 3’s design is NOT just to save money.

HW 2.5 isn’t about self-driving.

It’s about ride-sharing.

Screen-Shot-2017-08-15-at-9.43.37-AM.png


Conclusions

Despite misguided criticism, Tesla has not obsoleted Autopilot 2.0 hardware and this isn’t a “backup plan.” AP HW 2.5 is not about self-driving; it’s about ride-sharing. And Tesla doesn’t want to explain it — yet.

In short, with the Model 3, Tesla is delivering a mind-blowing electric vehicle that:





Incorporates everything Tesla believes is necessary for full autonomy

Incorporates everything needed to join its future ride sharing network

Will recognize you as you approach

Unlock your door and adjust your seat position

Restrict any parts of the car you’re not approved to access

Set the car to your temperature and aim the air vents where you prefer

Set all your radio presets

Queue your favorite streaming music or podcasts

(Someday) play your favorite movies and television shows



And, the “you” in question can be a complete stranger.

And all this happens instantly as you approach, without any manual interaction.

Expect more discussion on this from tech and auto industry reporters, and eventually the general public.

This is what Apple, GM, and others aspire to deliver three or more years from now.

Tesla isn’t going to explain it because, for now, they’d rather you buy an S or an X.

Despite keeping this secret they still have over 455,000 reservations. And counting.

The bottom line is that contrary to what Tesla says, the Model 3 is the most technologically advanced car that Tesla or anyone else has ever built.  

And it’s not even close.

Tesla is innovating at a rate unmatched in the auto industry. Not only are they planning years ahead but they’re also executing in a way that none of their peers can even conceive.

For contrast:

Mazda just announced a 20% improvement breakthrough in an ICE engine that it hopes to bring to market in 2019.  

Ford is adding 25HP to this year’s Mustang, and also adding a mute button, so the engine doesn’t annoy your neighbors.

These are ocean liners trying to catch a catamaran and they’re not even in the right body of water.

Is it any wonder Tesla accelerated their bond sale when it could have waited until 2018?

TMC Member Alketi is an electrical/software engineer with 25 years experience. He is also a Model 3 reservation holder.

What about the centre console arm rest storage area? On the Model 3 it is opened only via the centre screen, is that the same in the S/X currently or is there a normal latch to open it?
I saw in one of the videos that you just lift up on the center armrest lid. The lid on the lower storage near the dash is accessed by pushing on it and it springs open. Very easy.
 
The thing is, this is obvious and Musk has told us this is where they're headed. He has said that the Model 3 will be the cheapest car they will make because in the near future, opting into the autonomous Tesla fleet will subsidize the cost of the car. This is just proof that their hardware is ready for that to be reality.

I'm sorry, but by that strained logic... we WILL have a HUD (and whatever other nonsense we all expected/inferred that never materialized). The fact is, no... he hasn't "told us" that. He told us something that you interpreted in the way you interpreted it. And that's completely understandable... except for the pattern of reality that suggests it isn't reasonable. Think back to his "spaceship" comment... he really did "tell us" that the car would have a HUD (or something that would blow us away in terms of "steering system" [his words]), but in the end it was... wait for it... a steering wheel. Yippee. Now you're reading between fantastical sound bites and weaving an amazing tale of the future... that all makes sense but probably won't come to be.

I'm not being a pessimist. I'm an excited optimist who's been brought slightly down to earth as virtually EVERY self-pumped expectation based on Musk's 140-character limited tidbits falls short. HUD, range, price, options... every single step of the way we hold the pedestal so astronomically high with no where to go but down. And this conjecture about self-driving taxis from the 5th Element are just more of the same.

Do I hope you're right? Sure. Do I think you are? Not a chance.
 
We will see. Follow the news. It's mid 2017. In Nov 2016, before the order for Max Effort was given, they logged 3700 km with 6 disconnects. I wonder where they are now with 130 more cars running and 9 more months and another billion $?
So we`re talking about the same cars..........no extra sources or something unheard of so far.
Those aren`t level 5, not even close, they are "level 2`s with dreams" atm.....

And that mileage...that`s nothing.....that`s literally a toddler trying to move his head for the first time.
I´m not quite as pessimistic as Michael DeKort that #53 brought up, but yeah...we`re still very far from real fsd.
At least far enough that I do believe, that FSD is nothing that the first ~2 iterations of the Model 3 will ever have. Imho that whole Autopilot-tesla-fleet-fsd-stuff is hot air to keep the hype going without any factual evidence that it could be possible in the not so remote future.

Does anyone here appreciate cutomization of destinations presented on the touch screen?

This is a big deal for young and old alike. As it makes getting to the right place easy.

It is also important for increasing the participation of owners.

And starting with a finite set of proven routes. It puts rings on the ladder for the car.
 
I agree with everything in this post, but I would point out: the interior camera is not enough for me to send my Model 3 out for use by strangers. So you can catch people in the act of damaging your interior and ban them from using your car again. Great! But your interior is still damaged. Maybe the camera would deter many people, but kids don't think things through.

I see what you are saying and you make a good point. People who borrow the car may not even know that there is a camera so it may not do a good job of stopping people from damaging your car. However, I hope that it will at least provide evidence that they did indeed damage your car and you can press charges and get compensation.

Given how much trouble my loaner S had trying to pull itself into my average garage with summon, I think it's still going to be a long while before one of their cars can drive itself anywhere. Doesn't mean autopilot isn't cool; it is. Doesn't mean they shouldn't try; they should. But I'd place my bets on "not anytime in the near future".

As for interior camera, I place my bets on it being used just as an alternative to hands on the wheel nagging. That by itself would be hugely appreciated by a lot of folks.

I'm not interpreting at all. Here is the quote from Elon's Master Plan, Part Deux: "You will also be able to add your car to the Tesla shared fleet just by tapping a button on the Tesla phone app and have it generate income for you while you're at work or on vacation, significantly offsetting and at times potentially exceeding the monthly loan or lease cost. This dramatically lowers the true cost of ownership to the point where almost anyone could own a Tesla."

He is literally saying that once there is level 5 autonomy and regulatory approval owners will be able to opt in to an autonomous ride sharing fleet. I think it was in a shareholder call that he further clarified and said they didn't see the need to make a car cheaper than the 3 because of this cost offset.

Yes, there are a lot of things that need to happen first that are out of Tesla's control, but they are moving forward so their hardware will be ready once the technology is in place, whether that takes three years or 15. I'll admit it sounds crazy to even speculate that level 5 could possibly be here in three years, but 10 years ago how many people thought we would see the level of autopilot we have now in our lifetime?

This article is incorrect in at least one respect. The Tesla New Vehicle Configuration page plainly states the Model S will have Self Driving capability and it mentions "car sharing and ride hailing for friends and family is fine, but doing so for revenue purposes will only be permissible on the Tesla Network details of which will be released next year."

Furthermore it is my understanding there is no difference in computer hardware between a Model S, X or 3 rolling off the assembly line today.
 
I'm not interpreting at all
Yes, you are. Look at what you're quoting and the conclusion you're drawing from it. Ten years ago (from the time that was posted) he's talking about some non-specific point in the future. Nowhere does it talk about the model 3.

Just like his "spaceship" comment didn't turn out to be the HUD everyone assumed... you can't take vague Musk comments (particularly from a decade ago) and draw such specific conclusions that you are.

Look at the link again. Master plan part two was published just over a year ago. I don't have time to dig through transcripts to find where he has referenced the Tesla fleet in direct context of the Model 3, but it's out there.

Taking his statements from multiple occasions at face value and tying them to correlating hardware changes is nothing like extrapolating a HUD from a tweet about "spaceship controls." If you took "spaceship controls" at face value it would mean a tiny windshield and a dashboard with a whole array of buttons and switches. This article is using logical reasoning, not wild speculation. The equivalent for a HUD would be if we saw a projector in the dashboard pointing at the windshield, which we obviously haven't.

I'm not going to be paying for EAP on my model 3, because I don't expect it to be ready before I want to upgrade my car. Maybe they will surprise me. Nonetheless, it's clear that many of the ways the Model 3 is different from the current S/X are because Tesla is looking toward the future, even if they won't be fully utilized for at least several years. You're criticizing this article, but you haven't offered any alternative ideas about the purpose of the new features.

I don't understand why some people are so passionately opposed to the ideas in this article. Elon has also said that at some point in the future cars won't have steering wheels. If he shipped the Model 3 without a steering wheel "because that's how cars are going to be" that would be stupid, but we're not talking about things like that. None of these features of the Model 3 take away from the experience of driving it today, but they are there partially to accommodate changes that could be coming in the future.

Edit: I just re-read your original comment and I think I've been too harsh. Yes, I know I'm being an optimist, but I think Tesla is also operating in a spirit of optimism when they're including these features. And it seems to be a great time to be an optimist with Tesla - They met Elon's "impossible" goals of getting the supply chain in place for the Model 3 by July and got regulatory approval to start building them two weeks early. Like I said, I don't expect EAP to be ready while I have my first Model 3, but I would rather Tesla be looking toward the future than not and it's exciting to see them actively working toward Elon's dream, even if it's unrealistic at this point.

I think the leap between his comments and a HUD were *FAR* more understandable than the leap to assuming the 3 will be running around as a money maker for people. My point is... every time we speculate on what fantastical feature there might be, we're always later told we were silly to build it up so much. That's what this article is... building up. It is based on fairly solid conjecture, but conjecture nonetheless. Recent history has told me that this is unlikely to be a prediction that comes true.

But don't get me wrong. I'm fully on board with being super excited and vastly positive of what Tesla *HAS* achieved. I just think we need to accept those achievements on their own, and not inflate them with some what-could-come future.

With that said... your predictions are fun, and logically the pieces all fit, in theory. Of course, Trump *could* make America great again, I suppose.
 
I don't think that the standard Model 3 will be well designed to serve as an autonomous taxi. Taxis are designed to withstand a lot of abuse and they have to use better components than a standard car. You will need heftier doors and seat cushions that last longer and stronger seat covers (or seat covers which are easily replaced), and a water-proof floor covering that is designed to be washed or stronger floor carpet. People predict that the EV motors will last longer than the standard 200,000 miles because they have so few moving parts, but you might need a special motor if you expect it to run all day. Look at how the Yellow Cab and Checker Taxis are built and you get an idea how taxis need to be built. I suspect that Tesla will need to create a special model if it truly wants a car that doubles as a taxi.

Well done! It is nice to read an article that applies knowledge and wisdom. No political commentary; just an analysis of the facts. Keep up the good work. Now should I get an ice cooler for my Model 3 so riders can have a bottle of water? Need to keep up my rating for future business!
 
I don’t think you could’ve hit the nail on the head any better. This tweet from Elon himself today could have been taken straight out of your article:

“We are going to move all info and settings to the ‘cloud’ (aka server) so any Tesla you drive in the world automatically adjusts to you”

Well done sir.
 
Nice article. One area that remains unanswered is the wheel and pedals. As an autonomous taxi, would it be ok to leave these in place? I would say at the very least deactivate (mechanically disconnect) the wheel and brake pedal, or?

Tesla's plans for AP2 FSD do not involve being able to autonomously drive everywhere so you'd still need those and also in case of emergency.

...enabling full self-driving in almost all circumstances...
