Munro: Tesla Cybertruck Technical Specs DEEP DIVE with 5 Tesla Executives

[JBee]

7500 lbs towing on rwd

Model Y performance motors (basically) are used

Just at 1kV not 400V.

That's why the rotors are smaller as well.

This now finally confirms that the main pack and motor and inverter voltages are all at ~800V and that it only switches to 400V for charging. It also confirms that it's not all 48V, and that they still need voltages down the 0.7V for processors etc. Also some cool details on how they do the bidirectional charging and power-sharing, and how the 48V is made.

Active air suspension is also awesome, we can expect some really dynamic suspension control. Even mentions load paths in the casts! Crazy!

Really worth watching, despite the long adds.

I'll see if I can do a bit of a write up tomorrow with all the good stuff in that video that some might have missed. Finally some details on all those 4 years of design questions!

But now it's time for sweet dreams!

I wonder if they played with the idea when Elon said they will have a quad motor. Basically would the dual rear motor could also bolt to the front motor mounts giving a quad motor setup. If I was Elon I would have 1 custom Cybertruck with a quad motor setup because I can lol

Oh, you're saying double up on the rear induction dual guy. It sounds like they're hybridizing permanent magnet motors with induction motors intentionally. Doing that wouldn't lend to that design since the rear tri motor is induction.

They say they are doing Active Road Noise Cancellation using the speakers.

@45:28
They make a somewhat sneaky comment that "long term target is 500" miles of range with the range extender.

So maybe initially it's 460-470, but later revisions of the range extender will be 500+.

4680 improvements would do that im sure

Yesssss that's a big one. I don't think I've EVER seen a vehicle with full cabin active noise cancelling. I'm surprised this is only just now coming out, I would have advertised it like they did the exoskeleton.

The lowest/very vague voice comes out from Andrew when Mr.Munro asks if the cyber cell is all 'dry'. They arranged that part of the showcase to the last and short for a reason. I could not stop smirking whenever I think about that.

There is so much good stuff baked into the Cybertruck that it's hard to absorb all at once. I'm a guy that is not impressed with a bunch of doo-dads and features designed to impress, tacked on a crappy, out-dated platform, I want leading edge engineering at the core of the vehicle, and simplicity and innovation to make the vehicle better, more robust, all while costing less.

When you buy an F-150 Ford will list all the features (and almost anything qualifies as a feature because they want to pretend you are getting a *lot* of stuff for your money). So you see lists like this:

• Color-Coordinated Carpet with Carpeted Floor Mats
• Flow-Through Center Console with Stowable Floor Shifter
• Steering Wheel - Mesa Leather-Wrapped
• Unique Genuine Wood Interior Trim Accents
• Dual-Zone Electronic Automatic Temperature Control Open image overlay for Dual-Zone Electronic Automatic Temperature Control
• 12-Inch Digital Productivity Screen Open image overlay for 12-Inch Digital Productivity Screen
• Intelligent Adaptive Cruise Control Open image overlay for Intelligent Adaptive Cruise Control
• Ambient Lighting Open image overlay for Ambient Lighting
• Delayed Accessory Power
• Dome Light
• Fade-To-Off Interior Lighting
• Fully Flat Load Floor (SuperCrew® Models)
• Partitioned Lockable, Fold-Flat Storage Open image overlay for Partitioned Lockable, Fold-Flat Storage
• Gauges and Meters – Fuel, Oil Pressure, Transmission Temperature and Engine Coolant Temperature; Speedometer, Odometer and Tachometer
• Grab handles (A-Pillar) - Front, Driver- and Passenger-Side
• Grab handles (B-Pillar) - Rear, Driver- and Passenger-Side (SuperCrew® Only)
• Horn, Dual-Note
• Intelligent Access with Push-Button Start
• Rain-Sensing Windshield Wipers
• Lane-Keeping System Open image overlay for Lane-Keeping System
• Outside Temperature Display
• Power Door Locks with Flip Key and Integrated Key Transmitter Keyless Entry Including Auto-Lock
• Power-Adjustable Pedals with Memory
• Powerpoint, 12V
• Rain-Sensing Wipers
• Rearview Mirror, Auto-Dimming
• Reverse Sensing System Open image overlay for Reverse Sensing System
• Seats - Front, Heated and Ventilated
• Steering Wheel, Heated
• Steering Wheel, Power Tilt/Telescoping with Memory
• Universal Garage Door Opener
• Visors with Driver- and Passenger-Side Illuminated, Covered Mirrors
• Wireless Charging Pad

Etc, etc, etc. But it's all added to a platform that is ancient technology, I-beam underframe, leaf springs and cheap dampers (shock absorbers). The Cybertruck has most of the functionilty listed above (but Tesla designers and engineers don't even mention them). The Cybertruck has things that actually push my truck buttons:

12+ inches of active suspension travel with adaptive damping control with independent control of compression and rebound damping with only 10 msec response time.

Four-wheel independent suspension coupled with four-wheel steering increasing manueverability and nimbleness at slower speeds and stability and safety at high speeds and while trailering. The amount of power available from that front steering rack is impressive!

State of the art electric drivetrain technology.

Too much stuff to list, actually. And I haven't seen a list published by Tesla that includes all the things I find significant. One of the best parts was Tesla's lead of vehicle engineering, Lars Moravy, talking about the structural design of the exoskeleton. He clarified that the high-strength boron steel forming the door ring of the passenger safety cage was an integral part of the exoskeleton design (Lars is far more credible than the loudest and most strident exoskeleton denier).

The front and rear castings are made from custom alloys chosen for their castability, ductability and strength in an accident. He said they are surprisingly ductile for a cast alloy structure and emphasized how closely the design engineers worked with the production engineers to create designs that not only performed but were also very manufacturable. The ribs in the castings are designed to enhance the flow of molten alloy through the molds. I imagine this reduces casting rejects and shortens cycle times.

The opening of the motorized vault cover looked very smooth and quiet, without the noises of early prototypes. In terms of useability, this is the one feature that really stands out, it adds huge value relative to other trucks. Sure, the price of Cybertruck is high, but it comes with so much stuff that traditional truck buyers are accustomed to having to shell out extra for after the purchase. No need to buy a bed liner or a tonneau cover. The Bakflip tonneau I have on my F-150 is something I would buy again, if I had to do it all over again, but it sure is less than optimum in many ways, including lack of security (easy to break into), heavy and awkward to operate, the foam core is permanently saturated with water, it gets in the way when fully opened and cannot be walked on when closed. And it added over $1000 to the price of the truck.

Looking forward to taking delivery of a truck that doesn't drive like a truck!

Advertise! ... we don't need no stinking advertising ...

We got confirmation that the gearing is 15:1

15.02:1 to be exact. I was wondering when this stat was going to be made public. There’s a few other cool stats listed in the owners manual that I’ve yet to see.

 

[thedownwardmachine]

Came here to note two things from the video, one of which someone just pointed out -- the cabin ANC, which was news to me.

The other interesting thing was the 12V-to-48V adapter for jump starting the vehicle via existing vehicle tech. If they did that, it's conceivable there's a 48V-to-12V converter somewhere (or they can run the 12V-to-48V backward), though I didn't hear them mention that.

I like Sandy but listening to him is brutal. He really needs a co host that can help along the conversation.

Yeah I agree...I'm sure Sandy has a lot of experience but at the end of the day these engineers are way out of his league as it relates to how and why they do things. At the end of the day he tears down cars to try to understand the why certain things are done. From all the tear down most legacy oems are literally trying to build these things fast with the least amount of additional capital.

Tesla can do all these new cool innovations because they have a forward thinking CEO with $26 billion in cash to play with.

Legacy brands are hoping that their loyal fan base will just buy their brand if they make an electric vehicle...some loyal fans would prob buy...but I don't think all the non brand loyal people will. I believe Tesla is starting to realize they need to refresh their vehicles to keep them interesting. I believe the next gen affordable Tesla will be ready to be sold within 6 months of announcement.

When you listen to him talk, you can see him perk up when it comes to manufacturing processes and mechanical engineering topics, but he directly states that he doesn't know the software side of things, and by extension, probably doesn't know much about the new gigabit ethernet architecture.
I had a friend that worked there a few years ago and left before Cory left. I applied for a position, but they were looking for electronics costing people, of which I had some limited experience. I know they have engineers there that have deep knowledge on BMS and pack technology, but I'm not sure if they have anyone with knowledge on comm architecture or software engineering. If anyone from Munro is reading these threads, I can still be bought. My commute will be literally the same as it currently is. Look back in your submitted resumes around 2/14/22.
