> slow is fast, keep it at 60 if you want the milage meter to not die as quick This also works in petrol cars: the air resistance efficiency falloff is dramatic at higher speeds.

The use of AC / Heat will also just burn through your battery or your gas at a much faster rate.

The heat pump in the Tesla Model Y definitely uses electricity, but it is somewhat efficient. Much much more efficient than early model Nissan Leafs for a night and day comparison.

Sounds like you're an American who's either a Tesla employee or only owned American cars before. Their quality is mid-tier at best but the software appears to be so dangerous that I avoid driving behind/in front of a Tesla (in Europe).

I don't want a Tesla because I don't like how they look, drive, or feel on the inside, and the excessive tech bothers me. In other terms like speed, safety, and EV range, they're among the best, and I can totally understand why people besides me like them.

Btw, European cars are notoriously unreliable, aside from a few gems like Porsche.

I have a model Y. I hate almost everything about it. But most germane, The "Battery meter" at the top of the display is total bunk. That's got to be "rosy" numbers. It'll display a the battery in miles, but it's at least 25% inflated. However if you punch in a destination, you'll get exact numbers, and those are insanely reliable. It claims (and I don't believe any claims coming from tesla) that it'll factor wind, el…

I recommend tapping the battery meter to put it into percent instead of EPA miles (useless, misleading) and only estimate range using the trip planner, which is usually quite good.

"I like X, therefore any negative information about X is lies propagated by their enemies" is a dangerous position to take.

I like X and have had a good experience with X and negative information about X that conflicts with my personal experience with X may be called into question. I may even feel compelled to share my personal experience so that other people can have the same positive experience I have had.

The only way to show the most accurate estimate is to know where the driver is going, and many drivers don't always input their destination. It can also vary dramatically based on how you drive, and in fact, if you do have a destination, it will give hints if relevant (e.g. "keep speed below 70 mph to reach destination"). You can switch the EPA-rated miles for a battery percentage indicator by just tapping it in the…

Let's say you live in a state with a 55mph speed limit. The car has a lifetime average of 0.300 kWh/mi over 4 years of driving. It's December, ambient temperature is 20F and it is snowing. Your last 10 drives consumption rate was 0.400 kWh/mi because its cold out. There's A LOT of smarter things the car can do than use its factory set 0.250 kWh/mi consumption to spit out the range on dashboard. Erring on the side of…

It's not erring on the side of the absolute best state. The EPA-rated miles represent a standardized mix of highway and city miles.

The best state would be over 600 miles [1].

It's erring on the side of consistency, as it's also representing the battery's state of charge. It would only serve to confuse users to try and guess whether the current trip is a highway or city drive, will end in the next minute or two hours from now, which way the wind will be blowing and whether or not you're driving uphill, etc. It'd just be a useless guess, instead of an at least consistent one.

If you tell it where you're going, it already gives you a great estimate, as it doe stake into account all of those factors.

As a Tesla owner, I think the source of the confusion is the EPA range displayed in the HUD on the Tesla. We toggled ours to show the battery percentage, which is much more useful to us. We've never owned a gas vehicle that met it's EPA range and the Tesla is no different. No one takes EPA MPG * GALLONS of gas and expects it to be a real life estimate of range. Wind resistance increases EXPONENTIALLY with speed. Driv…

I think this is a problem because a lot of what people use to shop an EV is the headline range number, which you are declaring is not accurate. This is false advertising.

Sure, but isn't it up to EPA to fix their testing methodology to get better estimates? Why do we expect car makers to do that?

Rented a MY a couple months ago and was surprised how much I, and more surprisingly, my wife, hated it. Now, I despise Elon and the risky safety decisions of Tesla engineers, so I'm biased, but I wanted to give them a shot. Range was horrible. We drove about 100 miles and spent a couple hours over several sessions at superchargers. The handling and turning radius sucked. The controls were frighteningly distracting an…

You drive 100 miles and spent hours charging? That makes no sense. We're you towing something?

For what it's worth, I have a Nissan standard petrol car and it's pretty much the same. Every time I fill it up, it says I have 400 miles of range, then by the time I've driven about 300 miles, I've only got a few miles of range left. Interestingly the accuracy seems to get a lot better by the time I'm down to half a tank. I don't know if it's a sensor issue, or maybe my driving habits just change a lot when I have a…

Yes, my Mazda does the same. It will happily report a 450 mile (725 km) range on my 13.2 gallon / 50 L tank, when I have never gotten more than 380 miles. Sometimes much less. To be fair, if you cruised slightly above the speed limit on the highway in fair conditions and drove it to truly empty, I think you would actually get that. But the gauge reads empty when there is easily 1.5 gal / 5.7 L in the tank, so in practice there is no way you're going to get the stated range.

However, the key difference is that my gas car can be filled up anywhere, and worst case I'd need to get a gas can. Running out of charge is a flatbed tow, that's a huge hassle. The range being accurate is a big deal on an electric!

However, ICE is more efficient at higher free speeds unlike electric so there’s a higher sweet spot.

How so?

It is true that it's very accurate. I was on a trip that predicted 22% battery on arrival, and I had 21%. The last 5-10km were mostly descending down a valley, so lot of regeneration. Thus, when I arrived, 22%, as predicted.
