Examine many of the undocumented technical aspects of the Model S/X/3/Y/C that may appeal to the engineer in us! Since little of this is from Tesla, assume some data may be inaccurate. If you know more, we’d love to add to this list – comment below and if possible, add a source. Tesla makes many ongoing improvements that can change vendors or specifications between older and newer cars, but we’ll try to keep this accurate. (Oct-2024 update)
Acronyms – Use our Acronyms and Abbreviations to help in decoding terminology.
Active Aerodynamics – Left and right front flaps boost aerodynamic efficiency and range by only providing additional airflow when needed through the radiators. Original parts for the first Model S and X were made by Rochling. These flaps are only open about 10% of the driving time according to Rochling. (from the article in Auto Industries magazine Q1-2014, page 82). The Model 3/Y also includes its own shutter system as does the 2021+ Model S/X LR and Plaid, different from the original S/X.
Aluminum – The Model S skin and structure is 98% aluminum. The aluminum body only weighs 410 lbs (Dream Cars video Dec-2014). The Model X is similar. The Model 3/Y uses aluminum in the doors, hood, and trunk. The Model 3/Y fenders are steel, as is much of the structure on the orignal Model 3. With successive generations, Tesla has been switching the steel structure to cast alumium, reducing weight and assembly complexity.
Antennas
See our extensive antenna expose for the S/X/3/Y with photos and details for each antenna in each vehicle. The Model S Plaid is the king, now with 46 antennas!
AutoPilot HW1.0 – The system is based in part on the Mobileye EyeQ3 hardware/software, a front-facing camera, radar, and 12 ultrasonic sensors. (Computer Vision Video by Mobileye). Auto-pilot hardware was made available in all Tesla S/X cars produced from September 2014 to mid-October 2016.
AutoPilot HW2.x – The hardware includes Nvidia’s DRIVE PX 2 AI computing platform, estimated to be 40 times more powerful than AP1. In addition, the system includes 8 cameras, 12 longer range ultrasonic sensors (about 30 feet range), and front radar. The hardware is included in all Tesla vehicles produced after October 19, 2016 until 2019 or so. Two levels of optional software are offered – Enhanced AutoPilot, as a set of features that includes AP1 and more. A second Full Self-Driving (FSD) option is expected to provide Level 4 or 5 autonomous driving, once it completed and is approved by regulators (perhaps in 2025-2026). FSD requires a new processor called HW3.0.
The Tesla AP2 processor board includes an Nvidia PG418 MXM module. This board contains a GP106 GPU and 4 GB of GDDR5 memory. The GPU has 1280 CUDA cores and in this configuration uses 128-bit wide memory. Interestingly, the PG418 board has pads for an additional 4 GB of memory for use with a 256-bit wide version of the GPU.
The mainboard includes many additional parts, including an Infineon TriCore 32-bit microprocessor; a Blox NEO-M8L GPS/GLONASS/Galileo/Beidou module with sensors, and dead-reckoning abilities; and an Nvidia TA795 Tegra SoC with Dual-Core CPU, Quad-Core Arm Cortex-A57, and integrated Pascal architecture.
On the Model S and X, the unit is air-cooled with fans. In the Model 3, it is liquid-cooled using the car’s cooling system.
AutoPilot HW3.x – Tesla announced in late 2018 that the HW3 AP processor module is required for FSD. This module includes a Tesla-created processor that offers far greater performance than the HW2 platform. Most S/X/3/Y vehicles made after March-2019 include the new processor. Those owners that have HW2 and paid for FSD are being upgraded for free. Some owners who purchase the MC2 retrofit are also upgraded to HW3.
HW3.x uses two Tesla-designed processors, which improves the performance over HW2 by about 2.5 times. The new processors each have twelve ARM Cortex-A72 64-bit cores, running at 2.2 GHz. Each chip also contains 2 Neural Network Accelerators with 32 MB SRAM for each accelerator and an ARM Mali GPU.
The chip input can process up to 2.5 billion pixels per second, or the equivalent of 750 720p images at 36 frames per second. The image processor can handle 1 billion pixels per second.
AutoPilot HW4.x – In March-2023 Tesla started shipping the HW4 system in the S/X. The processor further increases performance along with newer higher resolution cameras and for the S/X only, a new HD front radar.
HW4.x uses two second generation Tesla-designed processors, which improves the performance over HW3 by about 4 times.
AutoPilot HW5 – Tesla has indicated a new chip is in development for HW5. Few other details are yet available. It may appear in vehicles in the 2026 timeframe.
AutoPilot Software (in 2020)
AP – This is a new variant introduced 28-Feb-19 that includes Traffic-Aware Cruise Control (TACC), Autosteer, and Auto lane change with a confirmation.
EAP – Now, discontinued, it offered on HW2.x vehicles, AP features above, Navigate on Autopilot on the highway, Autopark, and Summon. It also includes Smart Summon.
FSD (Full Self Driving) – For HW3.x vehicles, it adds to AP and EAP features: Navigate on Autopilot in the city, traffic light and stop sign detection, auto-lane change without confirmation. Additional features are not released yet. Customers with a prior FSD purchase will get the HW3.x upgrade for no cost. Customers who ordered EAP prior to 28-Feb-19, but where the vehicle had not been delivered at that date, will get FSD instead of EAP at no additional cost. Prior EAP owners can purchase FSD at a discount, which includes the HW3.0 upgrade.
AutoPilot 2.0 Cameras
Common color cameras use four filters – RGGB (red, green, green, blue) over cells to create a single color pixel (two green are used to increase the resolution/luminance. Most Tesla cameras use clear on 3 cells for monochrome and a red filter on the fourth cell (RCCC). This increases the monochrome light sensitivity, as color is not important, except for the ability to detect red traffic lights and taillights.
All but the rear camera is the same Aptina AR0132 camera (Aptina is now On Semiconductor). It is a 1/3 inch CMOS 1.2M device, capable of 720p at 60 fps. Tesla is using a visual field of 1280 x 960 at 36 fps. An additional 4 vertical rows of camera (not visual) data make each frame 1280 x 964.
The rear camera uses the OmniVision OV10635 720p CMOS sensor Tesla is using 1160 x 720 at 30 fps. SMK from Japan appears to be the company assembling the module. With the introduction of AP2, the rear camera module changed and has a built-in heating element. The module is connected via four wires – power and LVDS data lines.
For those owners that purchased FSD, Tesla is providing a free upgrade to newer cameras for cars manufactured from 1-Oct-2016 through 1-Aug-2017. Upgrades started to occur in late 2021 and are ordered by VIN number.

CSIMarket provides an up-to-date list of likely suppliers.
Operating System – Tesla created code running on Linux, written in C (PC World interview); Modified Ubuntu using the ext3 file system (Dragtimes). Early in the development Tesla considered both Android and iOS, but the key people at Android recommended against it, and Apple was unwilling to even talk to Tesla (Elon, video @36:10).
Vehicles- before version 8.1 (17.24.30) used the Linux kernel 2.6.36 for the center display. With the Tesla version 17.24.30, the kernel was updated to Linux 4.4.35. (Electrek). Functionally, there doesn’t appear to be any difference and no new features were added related to the OS upgrade.
Paint Color Codes – Tesla uses standard paint color codes. Some colors have multiple names or have changed names. You can also confirm the color on the label when you open the driver’s door. Look for the white label is near the bottom door jam. The paint code appears on the bottom line of the label after PNT. Check our in-depth article on Paint and coatings.
Patents – Tesla Motors has thousands of patents issued and many more pending. Lots of interesting reading!
Power Connector – Below the center arm-rest, the 12 v “cigarette lighter” power connector is fused for 15 amps. It is a switched circuit and power is removed when the car turns off. When the car is on, and the car is charging the 12v battery from the main battery, this connector’s voltage measures at 14.4 volts for cars with AGM battery and about 15.7 volts for the S/X with the Lithium-Ion “12v” battery (from our measurements and analysis). The Model X and Model Y includes a second 12v power connector in the trunk area.
Power Consumption – Using the Mobile Connector, after the car is fully charged the vampire AC power load is less than 2 watts! (from our measurements)
Processors – Our CPU report has over 60 processors on a fully loaded Model S.
Radar Transponder – Tesla uses a 77 GHz radar transceiver (from an article by Ron Freund in Jan-2015 Current EVents). The first radars likely used the NXP’s MR2001 chipset or similar and the chip consumes a negligible 2.5W when operating. The Radar system is present in all cars built after late September 2014 and until Fall-2017 were sourced from Bosch.
Vehicles with AP2.5/3.0 hardware, including all Model 3 and Model Y cars, used a radar assembly from Continental, the ARS410 CV, similar to the ARS404-21 or ARS408-21. It consumes under 7W typically, with a peak of 12W.
In mid-2021 Tesla discontinued the radar in the 3/Y as unnecessary, as the visual processing system works better without using radar, due to the frequent false radar information. In early 2023, the radar was no longer used on all Teslas after AP1.
HW4 added back an HD radar in March 2023 with the S/X.
Rear Camera – For the Model S 2012 this was a 720P HD 30 fps (from the 2012 OmniVision Press Release, no longer linkable). With HW4, the camera was upgraded to 5.1 MP and is the current standard in all new Tesla vehicles.

Special Access
- Diagnostic Access – On Controls -> Software, press the model name text (like Model S) for 5 seconds and release. A dialog appears that requires a password. The password is created daily inside the car and sent to Tesla’s servers. There may be some non-password options that work like DYNOTEST. Note that DYNOTEST makes your car undrivable, so don’t use it other than for dynamometer testing. Use “service” to access Service Mode.
- Ethernet connector – For the S/X via custom 4-pin connector behind driver side dash panel (only enabled via Tesla service through WiFi or 3G/LTE). A fleetwide software update in August 2015 added additional security to prevent non-Tesla access through this connection. With the 2016 Model S refresh, the connector was moved to behind the cubby. The 2021+ S/X moved the connector to above the phone chargers. The newer model Y has Ethernet access via an RJ45 connector under the dash near the driver’s door.
- Bug reports – If you have what appears to be a software bug, press the Voice button and say “Bug Report” along with a short description of the issue. Both screens will automatically be captured with the log, along with the message.
- Honk to manually save 10 minutes of video when the dashcam feature is available and active (and option enabled in Controls).
Superchargers – see our Supercharger SuperGuide.
Suspension – While components such as the Bilstein monotube shocks and Brembo brakes are well known in the early Model S, check out this excellent analysis by Edmunds of the entire suspension system with extensive photos and explanations. Many improvements have been made over the years. The current S/X now has an adaptive suspension system.
USB Connections – Depending on the car and year, there are from 2 to 6 USB ports available. Newer cars include a USB port in the glove box, which can be used for the storage of dashcam video or music. The S/X and earlier 3/Y allow the two ports in the center console to handle dashcam video or music as well. All other USB ports are only for charging. Some center console USB ports do not support dashcam video/music, likely due to the supply shortages (as of June-2022).
Check out our Accessory Power Guide for our detailed tests of USB ports for voltages and currents in the S/X/3/Y.
Devices that can be connected in the glove box and most front ports include flash drives, hard disks (with USB connection), phones, mice and USB diskette drives, and some music players. USB keyboards were disabled in software version 4.5 and later.
All model Y include USB-C connectors, and Model 3 vehicles made around Jun-2020 switched to USB-C style connectors as did the mid-2021 S/X.
To access music via USB, the drive must be formatted for exFAT, FAT32 or Linux Ext4 format. NTFS is not supported. See more on how to select and use a USB Flash Drive for Music.
Some USB-connected Android phones and tablets may provide drive-like memory access that the vehicles can see. This seems to be a bit hit and miss depending on the device’s design. Apple’s iPhone and iPod’s proprietary data format is not seen by the vehicle.
VIN Decoding – Try out our VIN (Vehicle Identification Number) decoder, supporting all Roadsters, Model S/X/3/Y and Cybertruck vehicles at Vin Decoder.
WiFi – b/g/i/j/n 2.4 GHz hardware support, but we believe b/g is currently enabled in software; Back in 2012, Tesla used the Parrot FC6050 W chip. Use WPA or WPA2 for the best security. Low-security WEP was supported in early software versions, but now smartly, it is no longer supported. With the Model 3/Y and S/X MCU2 and MCUZ after March-2018, 5 GHz is supported.

The model S 75 battery section states it has a capacity of exactly 75kWh…? I’m pretty sure this is not correct, and that it’s actually some number less than 75. Are you simply assuming based on the number 75, or did you validate this somehow?
At the time of the Model S75 release, the only data was that it was a 75 kWh pack, but it could be less. I’ve not been able to find a trusted source for the actual battery size. I even used to own a S75, but sold it last year. The label on the battery in my car indicated 75 kWh. Now that is not necessarily what the usable battery size is, which is a lower value to ensure longevity and safety.
I have a California HOV sticker. I was told I no longer needed to display the HOV stickers on my Model 3 . Is this true?
That would be nice, but no I’m about 99.9% sure the decals must be attached, no matter the car. I can see no changes at the CA DMV either about a rule change. Now some owners skip putting the stickers on and/or only put one sticker on, but they run a tiny risk of getting a fine if caught.
Do you have any info on the power available from the Model 3/Y USB-C ports? The manual says the wireless charger plugged into the front USB-C is 15 watts total, but nothing about the rear ports. In particular should I be able to charge my laptop at 60 watts (20v x 3a)?
I’d expect the rear to be about the same – 15W. Clearly not enough power for your laptop. In addition, USB ports are all 5V, not 20V that your laptop needs.
Check your USB-C spec. USB-C can provide 5, 9, 12, 15, or 20 volts depending on negotiation between the source and sink at at least 3 amps. With the optional Power Delivery protocol up to 5 amps or 100 watts max is possible. Some of the options depend on chips in the cable connectors confirming their capabilities. In some sense it’s similar to the charging options in the Tesla/J1772 protocols. If the sink only wants 5 volts then 15 watts is the max. If both source and sink agree to 20 volts then 60 watts is the max without the Power Delivery option. Since the Tesla ports are fed by the 12 volt battery I suspect they only provide up to 12 volts if, indeed, they provide multiple voltages.
I just went out and plugged the laptop into a rear port on my Model Y and there was no response, so I believe that confirms no 20 volt output. I’ve been learning a lot about this since my new laptop has both traditional proprietary and USB-C charging. By the way the laptop’s USB-C port is two-way meaning it can accept power input from a charger and also provide power output to an accessory, and data can flow in both cases.
Thanks for the extra details, I wasn’t aware that USB-C offered those options. Since Tesla only provided USB-A before, my assumption is the USB-C is simply wired to the old USB-A connections and has the USB-A limitations. It seems you confirmed that. There is no direct 12v connection to these ports as 5V power comes from the MCU. I also suspect 99+% of USB-C only supply 5 volts, but I can’t say I’ve tested them. I have tested the USB-A ports in the past.
I think that the definition of UDS is actually “Unified Diagnostic Services”. UDS is a diagnostic standard published under ISO 14229.
Many acronyms have different meanings in different industries. In this specific case, Tesla describes UDS as “Universal Diagnostics System” and is internally used by Tesla. My guess is the ISO document refers to some other usage.
Does anyone know where I can find information about the raw material usage in a Model S? I’m conducting a life cycle assessment and am having trouble finding the info.
Add? “The emmc chips differ by the way, MCU1 is 8GB Hynix H26M42001FMR or similar, MCU2 is 64GB Micron MTFC64GAJAECE-AIT.”

You say: SR – 50 kWh – 2976 total 2170 type cells in 4 modules; 2 modules with 23 groups of 31 cells each, and 2 modules with 25 groups of 31 cells each (from electreck).
==> This is the hardware for Model 3 Standard range PLUS => turned out to be 240 miles with Model 3. The actual standard range battery is a software locked version of the same hardware with a little less usable energy for 220 miles – just to fulfill what was promised before that. It would be interesting, what cell configuration the mid range battery is composed of.

https://cleantechnica.com/2019/03/08/supercharger-v3-shocking-power-smart-strategy-by-tesla-charts/
It’s unclear how reliable these charts are, but I suspect there are a good estimation. We’ll need to see the results from a production public V3 supercharger, hopefully soon.
Please add information on:
* additional CCS Interface on European superchargers V2
* Chinese charging interface
* Chademo adapter not working with Model 3
* the Supercharger V3 hardware up to 250 kW (test site at Hawthorne) for Model 3.
And regarding more hardware: here is some nice footage on an older AP1 model:

* Bosch iBooster braking system, communicating with the AP1 Mobileye frontcamera
https://www.youtube.com/watch?v=HsSxo4YJ6_U
* with CAN Bus to the yaw sensor
Additional interesting hardware list, that you could merge:
[www.teslorean.com/tesla-technology/] (dead link – moderator)
* and in the MCU 17 inch:
** 7channel audio amplifier (Premium)
** physical SIM card holder (mini SIM 25×15 mm) – no eSIM
** a fan cooling the Nvidia chip, that is prone to fail due to the cable being
** the 4 GB SD card on the back of the MCU board and some of its content like greylevel images from the front camera
The fellow promised another video about the contents if the SD card.
Good info. Sorry we don’t have any details of CCS or Chinese charging or the timing for CHAdeMO for the Model 3. We cover Superchargers and v3 in our Supercharger Superguide.
Can you give more insight on battery used in Roadster 2020 and compare to what was there in roaster 2010 , how much volt battery was used earlier compare to what they are planning to use in future.
Great questions, but Tesla has not released any battery details on the Roadster 2020 other than the range will be over 600 miles. The original Roadster battery is a nominal 375 volts. Everything else is just a guess right now! With two years until production, Tesla may not even have locked in the battery size. To work on existing Superchargers, a 400V battery is likely, but we expect a version 3 Supercharger announcement in 4-5 months which may be created in part for the new Roadster and other future vehicles.
Hi Moderator ,
Very excellent benchmark and anlysis, May I ask who supplies the ultrasonic system for AP1 and AP2? Somebody said that the detect range can achieve up to 15m.Thanks.
The ParkAid ECU ni 2013-2015 cars is made by Bosch, and presumably the newer ECU too. Not sure about the ultrasonic sensors. Keep in mind that the sensors have reduced range at higher speeds due to wind and buffeting on the sensors. They work best at stopped or slow speeds. So far Tesla has stated the sensors on an HW2 cars work to 9m or 30 ft.
Great resource! One small nit: in the section about cameras it says “Common color cameras use four filters – RGBB (red, green blue, blue) over cells to create a single color pixel (two blue are used to increase the blue sensitivity.” but this is incorrect. The common Bayer pattern is RGGB — two greens, not two blues. This increases effective resolution (not sensitivity).
Thanks! Not sure how I got that wrong, and I’ve now corrected it.
Just got the FCC alert about a new Bluetooth and 13.56mhz RFID antenna in the Model 3 B pillar. I can’t tell if they added any security to the passive RFID tag. Out of the box 13.56mhz tags can be cloned with an Arduino/Rasp Pi and some trivial decryption programs found on Google. Although the possibility of using a BLE secure two way handshake with an Apple Watch, iPhone or Android device seems a lot more secure. I’ve always wondered why the Model X bluetooth software hasn’t been updated to support local direct phone app auth. Relying on cell service of both vehicle and phone or watch is completely worthless. I could see a token process where the first request registers with the internet server, for X number of days of offline use.

Here I found some interesting Pictures an pinouts for the European charge port which is defined for 1-3phases AC (16,5/22kW) or 135kW DC:
[ed. page no longer available]
see on page 3 (German ony version) DC low charging (1*38kW):
[ed. page no longer available]
Or here on bottom of page 2 DC mid charging (defined for up to 70kW):
[ed. page no longer available]
I think that the contact material and contact springs are in a much higher quality compared to the Standard industry connector so that the European SuC is defined for 135kW.
Can someone confim that this is the pinout for the European SuC?
Where is the gps antenna on the rear glass left side? Does anyone have a pic of what it looks like? Thanks
Yes, it’s under the glass near the top on the left side on (driver’s side on LHD) cars. I’d estimate it’s about 1.5″ down from the top and maybe 0.75″ from the left side. The antenna is about 0.75″ square.

Thanks – We had it updated elsewhere, but missed it here!
If all 75/70/60(v2) kWh model use the same battery pack, does the software limit the “top” 20% of 75kW battery to make it 60? If this real, will below case happen?
1) If you set the charge limit on your 75kW to 80% to keep your battery healthy, you will get a 60kW but in high price.
2) Or you can order a 60kW version, and disable the charge limit, you still keep the battery well. Because the top 20% is software limit. Can someone confirm this? This should be able to confirm by record the near full charging current, it should close to a 75kW@80%
3) Or even better, even the battery degradation due to ageing, you still get “full” 60kW as the software limiter will try to limit those lost capacity
Good questions, but Tesla has never commented on how the 60 limited by software is implemented. There is lots of conjecture, but no confirmations on how exactly how it was done.
[…] are a lot of components in a Model S. According to TeslaTap, there are 432 lights, 50 motors/solenoids, 52 processors and a host of other complex machinery in […]
How can the battery cell count be the same in an 85 and 90? Wouldn’t the 90, producing the same voltage, have to have more cells for additional amperage?
“90 kWh – 400V, 7104 total cells in 16 modules, each with 6 groups of 74 cells = 444 cells, producing 25 volts (our conjecture, using newer batteries); nominal voltage 346 VDC
85 kWh – 400V, 7104 total cells in 16 modules, each with 6 groups of 74 cells = 444 cells, producing 25 volts (our analysis from battery photos); nominal voltage 346 VDC”
Great site!
Tesla changed the cell formulation for the cells used in the 90. Each cell now holds about 6% more power, but the voltage remains the same per cell. Over the coming years I expect cells will continue to improve so that we’ll see even higher capacities without increasing the size of the pack.
For Autopilot please add that the hardware (front facing camera, radar) was only built into Model S since a certain production date (Aug 2014). For Model S’s before that production date, the cars cannot be easily retrofitted as more of the onboard control architecture for steering and braking has beed changed in parallel.
I would also like to add, that on the Model S radar is *front* facing only, while competitors have two additional (rear left, rear right) additional long-range radars in the rear to detect fast rear traffic, which is important for lane changes. Using the ultrasonic sensors for rear vehicle detection may be fine in the US (with speed limits), but shows its limits in Germany, where there are cars overtaking a Model S much quicker, if the Model S driver actually wants to achieve the promoted range.
Thanks. I’ll expand this a bit. Note that most vehicles don’t have any auto-pilot features at all and you are right that a few have many more radars and cameras, usually at a very hefty additional cost. Surprisingly, in a competitive analysis these alternative systems were rated poorly in comparison with Tesla for auto-pilot features by Car and Driver. Extra hardware doesn’t always mean better design. http://www.caranddriver.com/features/semi-autonomous-cars-compared-tesla-vs-bmw-mercedes-and-infiniti-feature
Under Autopilot is says 10 ultrasonic sensors however the Model S has 12 of them, 6 in the front and 6 in the back. Does it not use all of them?
Yep, stupid error on my part. It does use all 12 sensors. I’ve corrected the details. Thanks for letting me know.
Couldn’t see anyone mentioning but sorry if I’ve missed, the audio also supports OGG files which made me very happy.
Thanks! I’ve added it to the list of supported Music formats.
Does anyone know if the SD card storage is accessible and can be replaced?
How large a card is supported? 64Gb, 128Gb? Is there anything Tesla-specific on the card or just music?
This seems an easy way to store a larger part of my music library in the car.
The SD card(s) are inside the MCU (the large 17″ display module). There may be more than one. For music, originally 16 GB was the default and 32 GB was installed for those that bought Sounds Studio (Now called Ultra High Fidelity Sound). It would require hours of disassembly to get to the cards as the entire dash must come out. It’s not clear if Tesla now uses a larger card or exactly what is stored on the card, so a larger card is unlikely to provide any benefit. Songs are not stored on the card, but that was the original plan. We think the space was consumed with map caching and added software features.
There isn’t any “greater” input power for the Superchargers in Europe at 380-400 VAC (220-230 volt per phase) compared to the North American market at 480 VAC (277 volts per phase). Only the cars in Europe are using a three phase charger not used in North America. The Superchargers use the same “single” phase chargers used in cars in North America.
It looks like assumptions were made with the 70D that aren’t correct. First, the car does indeed charge at 120kW (370 amps max at low 300-ish battery voltage.

85kWh pack – 7104 total cells = 74 cells in parallel * 96 cells in series
16 battery modules are connected in series. There are 6 sections in one module also in series, and each section of 74 cells is connected in parallel.
74 cells in parallel at 4.2 volts each in parallel * 6 * 16 = 403.2 volts pack voltage (max charge / regen)
74 cells in parallel at 4.15 volts each in parallel * 6 * 16 = 398 volts pack voltage (Open Circuit Voltage)

Thanks for the info. I don’t have access to the European Superchargers, but Tesla has stated on multiple occasions that European Superchargers provide 135 kW vs the North American 120 kW. This must mean the European Superchargers draw more input power from the grid. If you have the exact European input specs (from the label on the Supercharger), we’d love to know.
I’m assuming your numbers on the batteries is conjecture, but if you have an official Tesla source let me know! I should point out we don’t know for sure the exact battery cell details. Panasonic does not provide a spec public sheet on the cells Tesla uses (it’s custom for Tesla). I and everyone else have been going off the closest Panasonic spec sheet to what we think Tesla is using.
Your information on the 70 is in conflict and I have yet to get any confirmation on the actual battery structure for the 70. If the 70 pack voltage is 350V, then the Supercharger can only provide a maximum of 105 kW (like the 60). If it handles 120 kW, then the pack voltage is likely 400V. If you own a 70, and get 120 kW at chargers, then it’s likely the battery configuration is a 400V pack. The label on the battery should indicate the voltage. I’ve looked at two different 70s and the voltage part of the sticker is obscured by the passenger wheel well.
For music formats, the Model S plays 24-bit FLAC with at least 176KHz sampling rate. It also handles USB devices formatted with the EXT4 filesystem without any problems.
Antenna’s do not seem to be in mirrors:
Service notes
Correction: Antenna – AM/FM/HD Radio General Diagnosis
Diagnose vehicle AM/FM/HD radio. Check for pinch on antenna wires. The wires are ok. Lowered the headliner and re routed antenna wires and cleaned off ground for the Radio Antenna. Checked the reception ok at this time.
There are multiple antennas – in the mirrors and the rear-hatch. The radios use a system that switches to the antenna with the strongest signal. This is a common design in cars today, especially for FM radio. I’ve personally seen the antenna wires that feed into the mirrors.
It’s possible with the addition of electric folding mirrors that they had to remove an antenna, but I’ve not heard that yet (nor seen an electric folding mirror pulled apart yet).
I looked at a trace of network traffic sent over Wi-Fi from my model S. It looks like all traffic is encrypted and sent over OpenVPN. A portscan reveals that all ports are blocked on my car.
The Homelink Antenna is approx 3-5in to the Left of the frunk connector
Hi. The instrument cluster resolution is not correct. BMW’s is 1280×600, but the Tesla is 1280×480 which is more standard for automotive instrument clusters.
Yikes, I can’t find the source of the HD resolution now. I suspect you’re right, especially if they use square pixels as the ratio works out to be a 1280×480 display. What is your source?

Under ‘special access’, you can add that there’s an ethernet port for diagnostics/programming behind the side panel at the left hand end of the dash.
Also found out yesterday there are six sensors to detect the key. Two in the front, two in the back, and one either side attached to the back of the same panel as the ethernet port.

From the useragent string it looks like Tesla is using the Qt framework on X11. https://en.wikipedia.org/wiki/Qt_(framework)
It’s one of the best framework out there.
Why do we think it’s an Android variant, as opposed to a non-Android Linux variant? I thought I read the latter.
I thought I heard it from one of the engineers at the Amped-up event last June, but I could be wrong. The fact it integrates with Google maps, and they have said they will have apps and possibly third-party apps makes Android a good bet. It gets them so much further faster by using Android. Of course they could have home-grown all of it, but seems like a huge amount of duplicate work for what’s available for free with Android.
It was originally supposed to be Android, but they went to a different Linux-variant instead. I assumed it was because of the realtime functionality required.
may be they went to custom due to security, malware threats from apps which may cause potential or dangerous problems to thier cars and owners and eventually Company.
And no rare earth permanent magnets!
