    I have just ordered a 90D and like everyone eager to take delivery.

    Does anyone know :

    1. What OS the cars on?
    2. Can one download software to run on the system IE an email program?
    3. How big is the RAM and presumably its a SSD?

    Thanks so much.

    1. A variant of Linux, proprietary extensions
    2. No
    3. No! To be more precise, it might be on some cars but is definitely not user accessible.

    There are two sets of systems: the mission critical driving systems; and the user interface systems such as AV and satnav.

    Ubuntu for ARM with a custom kernel.

    2. Can one download software to run on the system IE an email program?
    Not without hacking the IC. It _is_ possible, but people who did this are not disclosing how they did it.

    Me? I've just bought an instrument cluster and the central console from a salvage Tesla in order to analyze them to get access to _my_ Tesla's computer.

    I think it is more like this:

    1. Commodore KERNAL
    2. Dialup
    3. 64 kB RAM + 20 kB ROM

    The CID (center display) is running a customized old version of Ubuntu Linux on an Nvidia Tegra 3 quad-core ARM processor. It has a 64M MTD NOR Flash drive partitioned into many sections for various purposes, along with a 16M SD card used for storing navigation data.

    There is also an embedded PowerPC based Gateway that runs openRTOS and has internal flash and a 4G SD card.

    Tesla's applications are written using the QT framework and since there is no source code provided, it would be very difficult to integrate your own applications, though with a lot of work, you could re-code their interface or just run some sort of overlaid system, but there isn't a lot of horsepower left for much. It is not an open system, and there is no easy way to alter it, and you risk getting your car to an inoperable state that would likely not be covered under warranty. Unless you are extremely skilled with Linux, I would not recommend attempting to modify anything.

    Thank you everyone for your humorous as well as the factual replies. I much appreciate the information. I was curious for many reasons and as its a dedicated system I am sure it is well sized for now and possible future tasks.
