    US 2021 Model Y Standard Range RWD battery type

    Tesla did build, deliver a limited number of 2021 SR Model Y. Some of the 2021 SR MY have the 7 seat configuration. I have seen a few 2021 SR Model Y. The 2021 SR MY vehicles look like the LR MY except for lacking the Dual Motor badge on the rear hatch.

    Mobile charger - Tesla or third party

    You may want to purchase the Tesla Mobile Connector to bring on trips. If you plug into a standard household 120V/15A circuit (using the included NEMA 5-15 plug adapter) to charge that will add up to ~4 miles of range per hour when charging. Overnight charging this way can add a decent amount of...

    New Owner - Want New Tires

    Another option would be to replace the OE Goodyear Eagle F1 tires with Michelin CrossClimate 2 (CC2) all season tires (for superior performance on snow and ice.) The CC2 is not currently offered in the OE 20" spec tire size (255/40R20) but some Tesla Model Y owners have installed the CC2 on the...

    USA MY RWD has soft limited LR battery!

    I always refer back to this earlier post, example (nod to @scottf200) of estimating the capacity of a Model X battery. The most important take away is that this method of estimating the usable capacity of the Tesla battery is that the state of charge when viewing the energy screen should be...

    USA MY RWD has soft limited LR battery!

    I have an early 2020 LRMY that came with a printout from Tesla stating that the usable capacity (when new) was 74kWh (This paperwork documented the usable capacity of the battery for a rebate program that was in effect at the time in Maryland.) I always understood the total capacity to be ~77...

    Am I right to expect ~200 miles range in winter? '23 MYP

    180 to 200 miles, in winter is a reasonable estimate. There are multiple variables that will impact efficiency and range with the greatest being your average highway speed. Colder temperatures, elevation changes (when climbing), wind and wet roads will all negatively impact the available range...

    HVAC vibration

    The Tesla Model Y's heat pump features a variable speed compressor. The compressor can spin at up to 9000 RPM. You may notice additional noise and vibration when the compressor is running at near maximum speed. This typically happens when starting to precondition the Tesla Model Y (especially in...

    Cold Weather Charging

    Cold temperatures won't be an issue for the battery unless it goes below -24F for more than 24 hours. If too cold to begin charging the Tesla Model Y will first warm the battery as needed, then charge. Vehicles need to be driven regularly. Your truck probably does not have soy-based wiring but...

    what PSI do you inflate your tires to

    You should always check the tire pressure when the tires are cold, i.e. when the vehicle has been parked (out of direct sunlight) for at least several hours. Early in the A.M. is usually a good time to check the tire pressure. The manufacturer's recommended tire pressure is always printed on...

    Cold Weather Chicago?

    I see the blue snow flake all of the time in winter. Normal driving is unaffected (you might notice the difference on a timed 0 to 60 run,) As far as range goes, simply driving will gradually warm the battery and then the normal range would be available. If you enable the blended friction...

    Cold Weather Chicago?

    It is common to think that you should install a charging circuit that terminates at a receptacle (outlet) but this actually can increase the cost of the electrical installation. Today, you would be better off installing the Tesla Wall Connector (designed to be hard wired). When you install the...

    3 weeks away should I leave plugged in

    If you set Sentry mode to exclude your Home location then you don't have to do anything to turn off Sentry when parking in your garage. Limit the number of time you open the Tesla app while you are away (especially if you leave the Tesla Model Y unplugged). Opening the Tesla app on your phone...

    Cold Weather Chicago?

    Newly installed EV charging circuits must be dedicated, i.e. no second outlet. This is now part of the National Electrical Code (NEC) for all new 120V and 240V EV charging circuits. You will want to get quotes from 2 or 3 licensed electricians for adding a 240V circuit for EV charging in the...

    Opinions on this charging plan

    Nothing is thrown away. When blended friction braking is set to on whatever percent of the regenerative braking that is possible is provided. If you don't set blended friction braking to be on and the battery is cold or nearly fully charged there is little or no regenerative braking, slowing of...

    Opinions on this charging plan

    Did you know you can now enable blended friction braking (See Pedals & Steering settings)? When you enable blended friction braking the Tesla Model Y will slow at the same rate when you raise your foot from the accelerator pedal regardless of whether full regenerative braking, partial...

    Tesla Model Y Standard (UK 73 plate) - 70-80% range efficiency?

    There is also the 3% "Tesla cold weather tax" that seems to infect Tesla vehicles starting at the beginning of winter. The Tesla Model Y will automatically adjust the estimated battery % state of charge and estimated range, downward, by 3% in colder temperatures. I imagine there was much hand...

    Tesla Model Y Standard (UK 73 plate) - 70-80% range efficiency?

    Short trips are the least efficient, especially in colder weather. The Tesla Model Y climate control system will use a significant amount of energy to warm up the passenger cabin only have the cabin cool down as soon as you park. Efficiency improves once your drive time exceeds ~30 minutes. Try...

    Update on replacing OEM 12v lead-acid battery with lithium?

    A large engine takes up more space under the hood. The engine generates lots of waste heat and vibration. The trunk may be the better, only location for the 12V starter battery even considering the longer cables. (May help slightly with weight distribution.)

    Update on replacing OEM 12v lead-acid battery with lithium?

    The original VW Beetle, Ghia etc. could not be built, sold today (i.e. placing an ~8 gallon gas tank practically in your lap just behind the windscreen LOL!) The 12V lead-acid battery (originally a 6V battery) was famous for leaking battery acid; the acid eventually eating through the floor of...

    Update on replacing OEM 12v lead-acid battery with lithium?

    Tesla's decision to originally use a flooded lead-acid 12V battery in the Tesla Models S, X, 3, and also the Model Y meant that Tesla was required to locate the 12V battery under the hood, in front of the firewall for passenger safety. The plastic case of a flooded lead-acid battery can rupture...

    range anxiety

    You would lose all power in the event the Tesla vehicle shuts down, including the electric power steering. Regenerative braking generates power but not enough to matter once your battery state of charge is below 0% and the vehicle is shutting down. You could start off at the top of a mountain...
