Thanks for the video, it's helpful to see other numbers to see how I'm doing efficiency-wise in mine. Here in central FL, there are no hills to really speak of, and if I do my commute as a (mostly) normal driver I have been between 230-245 Wh/mile.

My lifetime average is sitting at about 225 Wh/mi, having drifted up from 221 as the weather has coldified. Just put my winter tires on today, which will probably push it slightly higher again. I have the RWD model, though, so I have a slight efficiency advantage vs those of you with AWD.

Nice, Zaxxon. I had to go downstairs to check out my lifetime stats (never scrolled all the way down). After 2,532 miles I’m at 235 Wh/mi, used 594 kWh. I’m sure that’s going to keep creeping up as well during the winter. I see my range drop a lot more driving back and forth to work with the heater on. I would go from 73 to 55% battery for a 40 mile round trip.

Short trips in the cold are killer. You don't notice it in a gas car because 1) most people don't track range, 2) ICE cars are producing heat as a waste byproduct, so heating the cabin is done at virtually no incremental energy cost, and 3) they're inefficient enough that if there were a heating cost, it'd be noise. In an EV, we care about range, heat is an incremental consumer of battery energy, and the car itself is efficient enough that that cost is significant.

I track mi/kWh - but I converted to your crazy units ;) - 236.4. That's for 3356 miles from September until today.

I also track everything in a spreadsheet if anyone is interested in how it has changed as the temperatures have dropped - Bolt Energy Tracking.

So I’m addicted to one pedal driving. Now with the colder temperatures, when the regenerative braking is reduced, I get caught off guard as the car does not slow as quickly as I’m used to.

Stessier, that 13 cents for utility cost is great. For me it’s about 20 cents per kw (9 cents generation + delivery). So I’m about 4 cents a mile operating cost for electricity. I have some level 2 free chargers around me I use when shopping and hitting the library.

Yikes, $0.20. here in CO it's $0.11 or so.

Time for you guys to become another of the many, many people who get an EV and then get solar PV. It's one way to cheapify the operating cost of the car significantly if your house is a good candidate for PV.

Makes it easy to demonstrate that your car is fueled with clean energy when it's literally coming from your roof.

Simple question for you lot, I think.

Let's say I get to my in-laws place in the evening, can I plug it into a regular outlet to charge it? Like with a three prong plug into a regular outlet. How long would a full "tank" take to charge (long range and regular)?

If it is completely empty, it take 76 hours to charge to full from a 110V outlet.

But it seems unlikely you would arrive empty, nor would you need to charge it to full before using.

You will get about 4 mph on a standard 120 outlet. You can also use a dryer outlet to get much faster speeds, in the event that they have one in or near the garage. And if the garage 120V outlets are on a circuit not shared with anything else, you can cheaply convert them to a 20A 240V outlet to get 8 mph.

I found the trip odometer and "lifetime" I am at 268. A little more reasonable. Those last 30 miles must have been a lot of fun.

This time I am pretty sure the quotes around lifetime are appropriate, hepcat. It's a little shocking to me to note that in 4 months I have driven a little under 2500 miles. I am not getting the gas savings benefit I expected!

Figured I'd put these Wh/mi numbers into perspective since non-Tesla folks have likely never considered energy in that manner (lower is better):

My Model 3, including winter so far: 225 Wh/mi
Coop's drive-it-like-you-stole-it 3: 268
2019 Chevy Bolt: 283
Tesla Model X: 362
2018 Toyota Prius: 648
2018 Chevy Malibu Hybrid: 733
2019 Honda Accord: 1,087
2018 Mazda 3: 1,087
2019 Toyota Highlander Hybrid: 1,203
2019 MINI Cooper Clubman: 1,248
2018 Ford F150 (small 2.7L engine): 1,604

These are based on the EPA's 33.7 kWh/gallon number used in MPGe calculations.

I’ll be curious to see where my lifetime peaks after the winter. Currently at 235 (AWD non-p 18” aero) and I checked the last 30 miles yesterday during my normal work commute and it’s 287 (about 30 degrees, 72 cabin, 65 mph).

On a side note... We have one 10 kW EVSE in our garage, and share it between the Tesla and our PHEV. I plug the Tesla in as needed, but it's a little bit of a pain since the EVSE is on the other side of the garage and I have to unplug the Tesla whenever that car needs to come in or out of the garage, plus it's using the charger for a few hours nightly since it's a PHEV whose capacity gets drained each day.

I recently 'installed' my Tesla mobile connector in our garage (by this I mean it's plugged into a standard 5-15 120V outlet and cable-clamped to studs to keep the UMC cabling neat). That way I can plug the Tesla in all the time, albeit at a measley 4 mph charge rate. I thought, hey, Tesla makes a 5-20 adapter and virtually all modern housing uses 12 AWG wiring and 20A breakers by default, so I'll just swap that outlet out for a 5-20 and bump that up to 6 mph. That's a 5-minute job and < $5 in parts, plus the 5-20 Tesla pigtail adapter.

But no. My stupid house's stupid builder used stupid 15A breakers and 14 AWG wiring when it was built (in the late 90s!), so I'm stuck with this unless I want to run new wiring from the panel behind the house to the garage. Another annoying example of builders annoying homeowners by saving themselves pennies.

Yeah, I've got two freebies coming from the referral program, but I don't think it's worth the cost to me to install (new wiring, new breakers, possibly panel upgrade since we've already got a 50A breaker for the other EVSE) since I've already got the 10 kW EVSE. That single EVSE covers us just fine (it's about 38 mph for the Tesla). I was going to do this just to help my lazy self not have to plug/unplug cars 95% of the time.

I'm frustrated by the absurdity of the situation more than the actual impact to me.

You'd think that, but no. Our builder also went with the strict definition of '2-car garage,' in that it's 2.0000000000000 cars wide and long, and has a stair that comes down from the house door to the garage floor on one side. The cars only fit in the garage with the larger vehicle on the side with the charger and the smaller (the 3) on the stair side.

I'm also at 225 Wh/mi, at 775 miles with the RWD Model 3 mid-range. I have a 40 mile commute to work, one way, and the temps around here have been between 25-45 degF. Although I am cognizant that running the heater will drain the battery quicker, so I've been pretending I'm a B-17 bomber pilot, bundling up for my high altitude non-pressured flight.

I don't think we have anyone here that was on the fence but not yet purchased... But: Tesla is releasing any customer cars that can't be delivered by year end. They also apparently have stockpiled a bunch of cars at regional hubs and are promising delivery in time to get the full tax credit. They'll refund deposits if they can't live up to that.
