Technical Specs

edited November -1 in Roadster
Anyone have any technical details beyond what is posted on Tesla webpage? Tire size? Gearbox? Anything else?

    Michelin pilot sport cup 2 325/30ZR21 rear, 295/35ZR20 front. Y rated, same as 918 Snyder. (This info is from photos at the event. This may change, since model 3s at the reveal events all has 20’s, but only 18s and 19s available now, 20s will probably come with the AWD model 3 release)

    My guess is that Tesla will always use single speed gearboxes.

    I’ve got a founder’s roadster reserved, it would be nice to get an invite to ride in the roadster 2020 prototype.

    There are some Y tube videos that speculate about as well as possible. But not sure there will be anything official for awhile.

    Hello i have a question,
    what kind of used electric motor for Roadster? İs it induction motor?
    Can you give us some information about the electric motors?

    The original Roadster, S and X all use induction motors. The Model 3 uses a Permanent Magnet type motor - usually chosen for lower power output and slightly better efficiency.

    Other than that, no one in the forums knows what motor will be used in the Roadster 2020, although another induction motor is likely considering the power it offers.

    Just to add Model 3's is permanent magnet induction motor, as opposed to PM DC motor.

    Carlk, Permanent Magnet AC motor. Never heard of a Permanent magnet induction motor (probably because it doesn’t exist). Induction motors are called induction motors because the stator induces a magnetic field in the rotor; permanent magnet motors do not- because they have magnets.
    PMDC motors are generally thought of as brush commutated motors- like the battery powered motors commonly found in toys. Strangely and ambiguously, BLDC motors do not use brush commutation and are in fact PMAC motors.
    I have no interest in getting into a pissing match with you, so if you disagree, I won’t argue it.

    Impedance is a major issue, particularly for the individuals who live in thickly populated territories. Signs from different wireless networks can affect speeds, also some cordless telephone frameworks, microwaves, and other electronic gadgets.

    Ever play with walkie-talkies as a child? You may recollect how the units should have been on the equivalent "channel" with the end goal for you to hear one another. Furthermore, in the event that you happened to be on a similar channel as your neighbors, you could tune in on another person's discussion, regardless of whether they were utilizing a totally extraordinary set.

    In a similar vein, every single present day router can switch crosswise over various channels when speaking with your gadgets. Most routers will pick the channel for you, yet in the event that neighboring wireless networks are likewise utilizing a similar channel, at that point you are going to experience flag blockage. A decent router set to Automatic will endeavor to pick the least blocked channel, yet numerous less expensive routers ( will simply pick a predefined channel, regardless of whether it isn't the best one. That could be an issue.

    On Windows-based PCs, you can perceive what channels neighboring Wi-Fi networks are utilizing. From the order brief sort netsh wlan demonstrate all, and you'll see a rundown of every single wireless network and the directs being utilized in your region.

    For example, the majority of our networks and those of our neighbors are utilizing channels 6 and 11. By and large, for 2.4GHz you need to stick to channels 1, 6, and 11 since they're the main ones that don't cover with different channels (which can debase execution). 5GHz for the most part utilizes non-covering channels, in any case, which should make choosing the correct one a lot simpler.
