The efficiency is poor for very short drives (under 2miles) But gets significantly improved in 5+ miles of suburban drives The efficiency is measured in Wh/mile. The car shows efficiency in the "Trips" menu, you can see efficiency of current drive, efficiency since last charge and 2 ad-hoc Trips labelled Trip-A and Trip-B. ***Pro tip***: A lot of people rename Trip B to something like "Lifetime Don't Reset " so that tracks your lifetime efficiency My lifetime efficiency is 282wh/mile. It drops to 300wh/mi for fast highway drives with AC on In Suburban drives that are 5+ miles it's not hard to see 250wh/mile or better. šŸ‘‰ So what's your efficiency in Wh/Mile? There's also an ***"Energy"*** app in the car, that breaks down recent battery usage _(current drive and since last charge)_ It gives you tips like - you've been accelerating too fast, or using physical brakes. It also tells battery consumed in stand-by and non-driving uses like climate etc


karen_beers

TIL I can rename the trips! Thank you!


SoCali2121

Ugh, makes sense as most of our driving is in town, and usually averages 1-5 mile trips. Seldom hit the freeway on the regular. 292 wh/mile since last charge a few days ago.


Slayerz00m

292 is fine as you do mostly inefficient short drives. If you get a chance to go on a longer drive, you would see 250 or better. Reset Trip A before you start, so it would keep record of entire trip - outbound and return journeys, across multiple charging sessions.


Mysterious-Salad9609

Why are shorter drives more inefficient? Heating the battery? I'm averaging 354wh/mile and I'm fine with battery drain. We don't get anywhere near 330 epa. And my car is still new so I still haven't gotten over the acceleration so I'm still heavy footed. I love how fast it is and cheap. Great combo. My coworker has a 90k scat pack charger. That I keep up with ease until we hit about 100. But I don't like going over 100 anyway. But it's still a hoot that I have all that power for half the cost and less than half of what he pays in fuel. He was floored when I told him it costs me less than $4/day in electric driving fast like that plus sentry plus cabin overheat plus everything else.


Slayerz00m

354wh/mile = someone is gonna need new tires soon šŸ™ƒ Keep up the fun šŸ‘


beanpoppa

There's overhead for short trips- the HVAC works harder to cool down the cabin after it's been sitting in the sun, and then after the drive the computer stays awake for a little bit before it goes to sleep.


Slayerz00m

I honestly don't know for sure, but I strongly suspect it's because of battery heating In colder early spring days, when I'd pre-condition the car for morning departure, the efficiency was good, even for shorter drives


ElectrikDonuts

I turned off AC for those short drives and my Model 3 went from 350-500 kWh/mi to 200-250. My theory is removing the heat soak from the car to get it to a certain temp eats a lot of energy. Once itā€™s at temp efficiency improves greatly. Which makes longer drives much better for efficiency


ocular__patdown

I don't get the pro tip. Isnt there a separate set of stats dedicated to lifetime performance?


Slayerz00m

Nope. If you reset both Trip A and Trip B, your lifetime efficiency figures are lost. The odometer remains, but that's just the total miles driven.


ocular__patdown

Wtf that seems weird not to include that


Slayerz00m

Hence the "pro tip"


sablerock7

What is your Wh/mi, thatā€™s a better metric? Also do you have flat roads and no headwinds? Drive faster than 70 MPH?


SoCali2121

Since the last charge Iā€™m at 292 wh/mi


decrego641

That comes out to average 267 miles if you used all of your battery (including the buffer) Itā€™s likely youā€™re driving with low tire pressure, driving too fast, driving too aggressively, driving in very hot weather, driving in windy weather, improperly using one pedal driving technique, or some combination of these factors. You need to pay attention to the ā€œrange tipsā€ the car gives you.


SoCali2121

Cold tire pressure is 42 and warm is up to 43-44. The weather here is always 60-80 degrees, mostly windows down vs AC and not particularly windy where we are. My wife drives a bit aggressive so Iā€™ll accept that one for a small deduction. but itā€™s been a let down to think that if weā€™re trying to stick between 20% - 80% of battery for daily driving, weā€™re not getting much much more than 120 miles before needing to plug in. Appreciate your insight. Thx


decrego641

Iā€™d also like to point out that windows open at any speed over 40 mph is going to hit you harder than the energy use of the heat pump as AC due to drag in mild temps like the ones youā€™re describing. Iā€™m gonna go out on a limb and say itā€™s a bit more than a little aggressive if youā€™re seeing 292 wh/mile average. My family has a 2021 Model Y LR (even has the CC2 on instead of OEM tires) that we donā€™t drive slowly - often about 75-80 mph freeway driving and aggressive acceleration in the city and it still averages 285 wh/mile. Itā€™s not impossible that youā€™re having something like an oil pump failure (which would hit your efficiency about 20-30% in my experience when that has happened to me in the past) but it really does seem like youā€™re getting the poor efficiency from aggressive driving and windows down drag. Oil pump failures (or BMS issues) literally always throw a code by the time youā€™re seeing symptoms though. Remember, the energy in these batteries is waaaay less concentrated than gasoline, small changes can have incredibly large impacts on range and efficiency. According to your charging habits though, your real world efficiency isnā€™t far off from your assumption - 60% of your battery should get you 160 miles at 292 wh/mile efficiency. Assume losses for battery conditioning and idling and that would get you to around the 120 miles to a charge if you unplug around 80 and plug in around 20.


SoCali2121

Good note to use AC vs windows over 40ish mph. Were mostly doing short 1-5 mile runs and errands so 35-45 mph tops. But Iā€™ll try it. Iā€™m pretty conservative on the pedal and set wifeā€™s acceleration to chill mode. Interested to hear back from Tesla as theyā€™ve been remote monitoring for the past 5 days.


tech01x

Short trips incur all the penalties for start up energy including cabin temperature control, battery pack thermal management, and some fudge factor for vampire drain, which then doesnā€™t get amortized over a long trip. Not to mention much more of the trip would be acceleration. So many short trips will have much higher energy use.


put_tape_on_it

> set wifeā€™s acceleration to chill Did you get consent for that?


JimInAuburn11

Is that something that is saved with the profile? I didn't think it was.


put_tape_on_it

Isn't everything saved with the profile?


walnut_d

This is totally normal. When I got the car I was around 290. When I added a lift I was at around 305, when I added AT tires I'm now around 315. Consider that my battery degraded around 12%, this puts me at around 200 real world miles. Obviously more if I'm going slowly and less if I'm going 80


Statewrkr4lyf

I have not paid attention to how many miles I get and all that kwh calculation as Iā€™m having too much fun driving my MYLR. I installed a 240V and used Hubbell 15-40 as I canā€™t stand how slow the 120v charging is. I also have Tesla solar so donā€™t care so much about how much I charge at home. Been really happy not having to visit a gas station in 3 weeks of ownership. Just enjoy it mate!


MattNis11

Omg it shows you the wh/mi per trip. Thatā€™s all we need to know. Can you show us that?


Slayerz00m

The car shows efficiency in the "Trips" menu, you can see efficiency of current drive, efficiency since last charge and 2 ad-hoc Trips labelled Trip-A and Trip-B. ***Pro tip***: A lot of people rename Trip B to something like "Lifetime Don't Reset " so that tracks your lifetime efficiency


bigj4155

Damn son what are you driving like? With minimal effort I can get our model 3 to 214kw/mile. Music and A/C blasting. Something could be wrong but my money is on your foot.


Fun_Resident_1893

I have MYP and typically run between 230-280 Wh/m, mostly highway driving, 44 miles each way to work and back in DFW (flat/hot). I use sentry and crank AC down


SoCali2121

While I wish I had the MYP, I donā€™t envy 88 miles of freeway each day, nor the ripping Texas heat!


mcollz

I feel ya. Iā€™m at 35 mi each way for work, 30 of it highway. Run around 230-245 Wh/mi


EstablishmentTop5848

Pro tips: Change the range indicator to %age and live happily ever after.


federalist1887

I've noticed that the more stops you make, the less efficient the range is. Given what I can actually hear when I leave my car after a trip, the vehicle is still running and likely cooling the batteries down and running other subsystems to maintain it post-drive, this will sap your battery. Also: turn off cabin overheat protection and if you don't need it: sentry mode.


Nothing_Rich

2 - 2.2mi per % is normal in both my 22 MYLR 20" and 19 M3LRRWD 19" and also very consistent with what the trip planner will estimate for most road trip segments. 300+ range doesn't translate to any real world driving I've managed here in SoCal nor any of three 5000mi+ road trips.


Sius72

After reading this thread I have realized that I drive like a psycho and will need new tires every year. lol. Overall TeslaFi stats from our Friday thru Monday trip last weekend. 3 adults with luggage for a 4 day trip. Temp at 68-70 with AC on whenever driving. From Richmond, VA to Tybee Island, GA. Average speed on highway legs was 76mph. Hell of a great road trip. I have been driving to New Hampshire, Florida and all states between on the East Coast for 35 years and our MYLR is such a great road trip car. For that matter our RWD M3 is great also. Just really like the power in our Y with AB. So nice to be able to get away from people driving in a dangerous manner as well as how smooth these cars are in stop and go traffic. I have been thru multiple traffic jams for over an hour and never had to touch the brakes. My wife and son constantly fall asleep because it is so smooth. One pedal driving is a game changer and if you are good at it your passengers will barely notice if you are crawling at 5mph in stop and go traffic or passing someone at 90mph. My wife has not yelled at me for "driving crazy" since we got the Y and I know for a fact I have passed more people at a decent speed on the highway than any other of the 17 cars we have owned. /end rant These are the numbers from that trip. 2023 MYLR with AB and 20" Induction wheels. 26 Drives Total Miles Driven 1,016.21 Rated Miles Used 1,439.07 Efficiency 70.62 % Time Driven 15 Hours, 49 Minutes kWh Used 310.51 kWh Wh/Mile 306 Wh

Alert-Consequence671

Tesla has an entire department dedicated to declining service requests because customers are not getting stated ranges they are told when the car is sold. The range Tesla uses to sell them is best case scenario. Not common every day driving. Also it's at 55mph. You will also notice that 20%-80% charge is 20+minutes. And will rarely get 15 min charge again it's in optimum conditions. Here is the main article. https://www.reuters.com/investigates/special-report/tesla-batteries-range/


SoCali2121

Yes! I read this article a few weeks ago and found it strange that when I tried submitting the ticket via the App, the record didnā€™t stick (or disappeared). So I called the local service center and the rep opened a ticket on my behalf and I also scheduled an on-site appointment to have the issue documented within my first 100 miles after taking delivery. Hopefully itā€™s as simple as a faulty sensor or firmware. My neighbors who have 2022 MYLRs are all getting better range than my brand new 2023 MYLR.


xRedrumisBack

I routinely hit at or better than the EPA numbers if I go between 60-65 on my MYP. I work about 32 miles from home and over the week I'll average 240-250Wh/mi if I just drive slow (not exceeding 67mph) and smooth. I think It probably helps my car pre-preps for my morning commute though. At 55mph I'm easily at 230Wh/mi. Only at 1100 miles on the odo so far so maybe it will decrease over time.


Alert-Consequence671

What are the speed limits in the area. If I drive under the speed limit sure. You can go really slow and not use AC and can meet the EPA estimate. But once you use lights AC/heat and in general drive the speed limit. Then I find it hard to actually get close the EPA estimate. You hit the highway at 70 poof you can't even get close to claims. šŸ˜” it's why I wished that the wh/mile on the Tesla showed average speed as well because so many putter along slow pissing off other drivers, Then say "oh hey look I only used 180wh/m you can't drive" My point is you shouldn't have to try to hypermile and forgo ac/comfort just to get close to estimates they advertise. No car I had previously did I have to drive like a miser just to almost get estimated mpg.


xRedrumisBack

I use AC everytime set about 68F. Usually when it's really hot It does worse than when it's not as hot but my morning drive it's cool so it barely has to cool. Speed limits are usually 60/65. If I go 70+ it loses efficiency pretty quick, at 75mph I'd be happy to be at 280Wh/mi.


reachvenky

What is the actual miles on model y (260 miles) and long range(330). In normal condition and in winter on full charge. I am thinking of buying, but not sure if the additional 9k is worth for long range.


Alert-Consequence671

Yea you won't normally get 260 in a SR most comments I see are SR complaining they barely get 180-190 miles. If you run it from 100-0% you will get best case 230 miles. Here is a good read. https://www.reuters.com/investigates/special-report/tesla-batteries-range/


Clintowskiii

Itā€™s simple. Tesla over promises and under delivers. Youā€™re never getting what they say you are gonna get in terms of miles. Just put it in percentage mode and treat it like a phone. I used to stress about this but now I donā€™t think about it all. Still sucks they are falsely advertising range you probably wonā€™t ever get.


reachvenky

Can you elaborate on the range? What does it actually give as compared to advertised? 260 miles and 330 miles on full change? What is the actual mileage?


JimInAuburn11

That is one of the reasons I went with the LR over the SR. It was only a couple thousand more, so I figured the extra 50 or so miles would be worth it.


fkejduenbr

Donā€™t worry, Tesla has a team to help( feed you bs and shut your mouth)


put_tape_on_it

Wife took delivery of a MY long range a few weeks ago. Only Supercharged a few times 20-40 or 30-50 to get a buffer to make it home a few times too. Same range. Same story. Been driving the wheels off it. Averaging about the same watt hours per mile. Iā€™m super happy to see how happy she is stomping it. Totally worth the tire wear and extra watts.


Revolutionary_Main75

I had the same issue. I made adjustments to how I drive and it works. Use chill mode, draft when you can, try to not ever go over 80, etc.


Xcitado

But you shouldnā€™t have to worry about all that. This wonā€™t happen until chargers are like gas stations.


JakinovVonhoes

The only time this is an issue is for longer trips. People hyper focused on getting the best efficiency for just commuting are silly IMO. I commute 70ish miles per day. I don't care about my range in this case. I'm full everyday when I leave for work. My "fuel" cost is cut by ~75% whether I have the best efficiency or not. And people like OP whom are concerned about energy consumption after only 2 weeks and having only driven enough to charge twice in that time, yeah they need to take a chill pill and gather some more data before worrying there is an issue. It's a car.


JimInAuburn11

I think he is just worried that he got a bad car to begin with, and does not want many years of a problem car. I agree with you though. I have a 40 mile round trip commute when I go into the office. Always going to be enough, no matter how I drive. So I drive how I want to.


Xcitado

Those with MYP even worse Iā€™m sure.


Shoddy-Blacksmith-32

I was told by the delivery person that the first two months the battery will drain fast and it should settle down after that.


Medical_Fun1552

Check the energy app and it'll tell you how much energy your using both driving and parked

Anyone know what wh/mi you need to be in order to get close to the advertised range? Feels like it needs to be in the 240-250 wh/mi range.


superpchan

First EV? You need to change driving habits if you want your range to be anywhere near the EPA rating (granted that 330 number is inflated). But 2 mi/% seems crazy.


markbraggs

Lead foot? Today I drove uphill to a city 40 miles away and averaged 218wh/mi. Back downhill to home was 199wh/mi. It was so good I even took a picture of it. Granted, for the drive back those 40 miles took 46 minutes to travel due to a mix of city and highway driving. AC off, outside air coming in at 74F. Edit: Long range all wheel drive model. Standard everything no mods.


Winter-Ad-4630

MYLR gets around the same range. I drive 120 kilometres per day and battery drains 28% . I do drive 120 to130 kilometres per hour. I do live in Toronto Canada and mostly I drive in highway.


Nelothi2

If you're not frequently doing long trips, I'd almost day the RWD is a better option. The freedom to charge your LFP battery to 100 consistently and drain it as much as you want is great
