AWD + 19" Mileage discussion

AWD + 19" Mileage discussion

I know there are a number of threads on mileage, but I don't see any based on configuration. Can we discuss what mileage you're getting with AWD and the 19" wheels? I know it's early, but at just under 400 miles, I'm at a lifetime number of 321 wh/mi. This is 90% city driving, with plenty of stop signs and red lights. When I give test drives, I or the "test driver" is definitely punching it. But that's a small number of miles. I'm not babying it for normal driving, but I'm not driving spiritedly, either. Just normal driving most of the time. When I am babying it, my 24 miles round trip to work and back usually results still over 300 wh/mi. Drives of 250 wh/mi are extremely rare.

A 321 wh/mi would get me about 233 total mile range, which is pretty far off from 310.

I have a slight alignment problem. Could this cause such a drastic decrease in mileage?

i'm at 275 wh/mi, with 607 miles on the odometer.. same 19" AWD configuration. I know i was consistently over 300 wh/mi for a while, but now notice things are calming down (either my driving or the car, or both)

misalignment can cause decrease in mileage, not sure that drastic though

jahshuwuh | 12 octobre 2018

I'm seeing an average around 300 wh/m, AWD+19" wheels, 764 miles on the odometer. Not much spirited driving, I've been trying to drive as efficient as possible (no climate control when I can). I've read some people say it gets better after the car breaks in, so we'll see. I've had the car about 2 weeks now.

AWD with 19's, 860 miles on the odometer from a combination of city, highway, and stop and go commuting on the 101 in Los Angeles - averaging 270 wh/m.

sroh | 12 octobre 2018

Give it some time and more miles. I have an AWD with 18" wheels, but have driven exclusively with the aero covers off. I started off around 300 wh/m for the first 500 miles, but have settled into 260 after 1,500 miles.

But definitely have the alignment fixed.

nttesla | 12 octobre 2018

Mine has 1600 miles and I am at 227.

Jlomb436 | 12 octobre 2018

WOA there nttesla, that's some awesome mileage.

I have about 2500 miles and lifetime is 265. I do not granny it. If there is a red light, I like to have fun up to 40 mph or so. I usually drive 70-80 on the freeway.

One thing we should all be including is our weather. I think that's going to be one of the bigger factors. I'm in Southern California, so average of 65-75 degrees outside.

Jlomb436 | 12 octobre 2018

And I forgot to mention, isn't the usable 78 KW not 75? OP, that would make your real range 244 vs 233. Not saying that's great range, but let me know if I'm off on the battery pack size.

afcop2 | 12 octobre 2018

RWD here, I had originally configured AWD, but when the efficiency rates came out that showed RWD was more efficient, I swapped over. I am glad I did based on the wh/mi I am seeing in this thread vs what I am getting.

WardT | 12 octobre 2018

The weather is perfect in SoCal (70-80 F) and my RWD M3 has a lifetime 251 Wh/m. We probably have the AC on most of the time, but never the heat. It started out higher and has slowly dropped down probably because I stopped hot rodding around. That is mostly city driving as we have taken only two long distance trips of more than 150 miles. We have just over 6,000 miles on our little baby picked up in March.

WardT | 12 octobre 2018

And I have the 19” wheels.

slingshot18 | 12 octobre 2018

OP here. SoCal resident so weather shouldn’t be an issue. I run AC all the time but it’s barely doing anything this time of the year.

sroh | 12 octobre 2018

As a point of reference. our RWD is at 239 wh/m over 5K miles. Also with 18" wheels and aero covers off most of the time. Similar driving as our AWD, so I can confirm RWD is more efficient. Easily 6-8%.

OP, one other question. Do you keep your cabin overhead protection on? That definitely sucks up miles while sitting and will have a negative impact on wh/m.

ODWms | 13 octobre 2018

PD3+, and I’m getting 240s consistently when I’m on surface roads. Overall, I’d say I’m at 280s on average though (I do a lot of highway driving. Gotta say, I’m very impressed with this car in so many ways.

jasr | 13 octobre 2018

AWD, 19”, San Diego:

Only have 500 miles, but I am averaging 250wh/mile. On short trips it typically runs > 350 wh/mile. Drove to LA driving at ~ 75 mph and averaged 260wh/mile. On the way back, I kept it below 70 mph and averaged 230 wh/mile.

P3D, stock 18" - I get 400wh/m, wife gets 275 wh/m...I have 99% pb foot, wife is 40%

ncancilla81 | 13 octobre 2018

In my RWD w/19’s under normal conditions, I’ll be in the 250’s. In my P3D+ under the same conditions 270’s. What I normally average in the RWD, 260’s. In the P3D+, 300+. In my opinion you shouldn’t be under 300 in the P3D:)

I drove the Jaguar I-Pace last weekend and It’s listed at 234mi for a full charge. I highly doubt it would even go that far on a full charge.
The acceleration was on par with my RWD 3 and I was impressed with the way it handled. I like the size and it looked pretty sleek in blue. The touchscreen was a complete mess though. Way too many menus to scroll through and not very responsive. Tiny screen compared to the Model 3.
The I-Pace made me really excited for the Model Y, since the size of it makes so much sense.
I’m just really surprised how bad the range is for a 90kWh battery.

kevin_rf | 14 octobre 2018

AWD, 18" Wheels, Chill, New England, 80% highway, rest rural back roads, 2500 miles, lifetime at 235 wh/m.

Was lower, 230 after 1000, I seem to get lower mileage on 190 and the Mass Pike than I do on 495. Speed plays a large factor in how many electrons I burn. 495 is usually a parking lot.

Gray Dragon | 14 octobre 2018

Awd 19’s. 246 lifetime, 2500 miles. Commute with mostly highway driving with some stopping due to traffic in sf east bay area.

slingshot18 | 15 octobre 2018

@sroh Yes, cabin protection is on, but the weather has been mild lately and I don't expect it to be doing much right now. Got another 100 miles this weekend and lifetime is at 318 wh/mi. It isn't really moving much lately and I'm worried it won't.

I appreciate the other points of reference, but I was hoping to keep this thread to just AWD with 19" wheels to help us AWD/19 owners have easy place to review data.

staze | 15 octobre 2018

Depending on where you live in SoCal and your commute, the hills a a factor as well. Hilly terrain will require more electricity than pancake flat areas.

slingshot18 | 19 octobre 2018

So I do have an elevation change on my daily commute. 662ft to 1157ft and then back at the end of the day.

I'm now at 664 miles with an average of 308wh/mi. Mostly just drive normal, with some spirited driving once in a while, but also some grandma driving to try to get the efficiency better. But I seem to be plateauing around just over 300wh/mi. Weather continues to be pleasant, so not much AC or heat.

Could elevation account for all of the poor efficiency numbers?

tigerkc | 19 octobre 2018

AWD + 19".
Temperature range is 55 - 80F, sunny, low wind.
Odometer at 654 miles and 256 wh/mi overall, 90% highway (65-80 mph), 10% city stop & go. On average, rate mile is 2% higher than actual mile.

JAD | 19 octobre 2018

Be sure your tires are in the 42-45 psi range COLD. Also, the biggest factor is how fast you drive on the freeway, not how you accelerate. 65 mph should get you rated range, 85 mph will be 300+ Wh/mi usage.

slingshot18 | 19 octobre 2018

My tires are 42 cold, 45 warm.
Regen is in standard.

It’s either the elevation or something is wrong with my car.

JAD | 19 octobre 2018

@slingshot, you never said what speed you drive? 85 to keep up with SoCal traffic?

slingshot18 | 19 octobre 2018

Almost all side streets. Freeway is less than 10%. Fastest is 55-60 on daily commute.

slingshot18 | 19 octobre 2018

If I hit the freeway, yes SoCal speeds, but easily less than 20 miles at those speeds.

Average is probably 30-35.

russr1123 | 19 octobre 2018

I'll chime in here even though I have the 18" aeros. I'm averaging around 260wh/mi with about 600mi on the odometer. Keep in mind that a large part of that is from the warmer weather here in the Northeast. With the weather in the 40s to 60s, my Wh/mi have dropped a bit. I'm driving all local roads ranging from 30 to 55mph pretty conservatively, but my average speed is probably around 35mph. There is some starting and stopping at lights and so on and my commute is about 14 miles each way. If the weather is nice, I can get around 240 Wh/mi going to work, but my average coming home is always higher around 260 Wh/mi. Rain adds like 40Wh/mi more.

In general, it seems the AWD is not nearly as efficient as the RWD as I see people with that posting numbers around 200Wh/mi.

slingshot18 | 19 octobre 2018

I know AWD is lower efficiency as RWD. I’m not comparing to RWD. I’m trying to compare to other cars of my config to see if there is something wrong with my car. Even though 240 is the stated efficiency of the car, I’d be thrilled with 260. Even 280. The 308 I’m getting is worrisome.

jamesacarroll3 | 19 octobre 2018

AWD + 19” wheels. Round-tripped from Dallas to Portland (6k miles) driving 80-85mph most of the way and logged 293 wh/mi. Slowing down will definitely improve this metric.

garibaldi | 19 octobre 2018

AWD + 19" wheels. I do 70% city driving often with traffic. I go down 570 feet and up 300 feet one way, and the reverse on the way back. I'm getting between 70 to 75% efficiency, or 217-232 miles. And it's not winter yet.

russr1123 | 20 octobre 2018

slingshot, I don't think I made my point clearly. What I was trying to say is that 308 is pretty normal. I'm getting 260 to 280 only because I'm trying super hard to drive conservatively and keep the energy bar in the middle as much as possible. On top of that, I've got the 18' aeros and I keep my tires at 45 PSI cold. If I just drove normally, I'd get the same as you and possibly even higher. When I showed my co-workers the car yesterday for example, I punched it once and drove normally and I got 421Wh/mi. So if there's something wrong with your car, then the same thing is wrong with mine :).

slingshot18 | 20 octobre 2018

@russr1123 I'm having a hard time believing 308 is normal (up to 311 now). I can't get 260 on my round trip if even if drive like a grandma. And from the data I'm piecing together, the only people I see over 300 are the ones admitting to driving aggressively most of the time (I'm not) or commonly driving 85mph+ on the freeway (I'm not).

@garibaldi Those are not great numbers either, like me. Your total change in elevation is less than mine, but our numbers aren't that far off. Are you driving aggressively?

cantak | 20 octobre 2018

19" AWD, 295 Wh/mi @ 1834 miles. I drive normal. No hypermiling, occasional bursts of fun pedal to the floor acceleration. Mostly highway.

garibaldi | 20 octobre 2018

@slingshot18 Not aggressively, but through a lot of slow traffic, with several lights on the way. A 16 minute commute easily becomes 30 minutes.

Going up and slow wastes more battery, I guess.

This is what TeslaFi is giving me. Notice how my efficiency is better with lower temperatures because in the morning I'm going down the hill:

Temperature Wh/Mile Efficiency % Miles Recorded
5 to 10 C 293.17 75.6 50.38
10 to 15 C 285.71 77.6 75.39
15 to 20 C 295.05 75.1 93.17
20 to 25 C 313.71 70.6 10.36

(also TeslaFi doesn't have the whole driving history; it didn't get the first week or so)

garibaldi | 20 octobre 2018

By the way, when using CHILL the numbers are way better. Have you tried it?

NOC8H18 | 20 octobre 2018

AWD 19" located in Michigan, after 2,695 miles I'm at 278 Wh/mi. Daily commute is 44 miles roundtrip with stop and go traffic, recently took a trip to northern Michigan and was averaging ~290 with speeds ranging from 77-85 on the expressway to 50-60 on the local roads.

mountainjoe | 20 octobre 2018

AWD with 19” wheels - so far 264Wh/mi after 1,253 miles and I live in the mountains so lots of ups and downs. Pretty happy with the mileage.

slingshot18 | 20 octobre 2018

@mountainjoe WOW! That’s incredible and pokes a hole in my elevation theory I suppose. I’m now leaning more to something being wrong with the car.

Randkthorn | 20 octobre 2018

AWD 19” 3000 miles, some driving like a teenager, demo-ing acceleration for folks, etc. 264 Wh/mi.
Compared to previous cars I’ve owned it’s like a super car or bat mobile, so I’m sure my Model 3 is more efficient than those.

scwilliams52 | 20 octobre 2018

AWD 19" with 775 miles and I've been hitting it fairly hard. Love to launch it. I'm at 273 Wh/mi avg. Probably half of my drives have more elevation gain than you are saying, considerably more. But 75% of my miles are on freeway with half of that at 70 MPH. I see big swings in my average Wh on different drives, so it could just be how you are driving. Make sure your regeneration is on standard.

russr1123 | 20 octobre 2018

What are your tires at? Keep then at 45 cold and I guarantee you that you'll get good mileage. If you don't, then maybe it's with a visit to the SC.

djgarrett21 | 20 octobre 2018

AWD 19" and ~1500 miles I've got a lifetime average 250 Wh/mi.

Coming from gas vehicle it seems the efficiency of an EV is much more sensitive to just about every variable. I averaged about 325 Wh/mi when I first got the car. After 500 miles my average dropped to where I'm at now mainly due to me learning to drive more efficiently. I focus on using regen as much as I can, that makes a huge difference.

My driving profile: 75% freeway (75 mph) and generally easy on the "gas".

slingshot18 | 20 octobre 2018

Regen is standard and I use it all the time. Rarely use the brakes. Tires are at 42 cold as they were delivered. 45 warm.

jarvis123 | 21 octobre 2018

AWD and 19”. Central Virginia. 3000 miles since September delivery. Average 251 Wh/mi. Mostly commuting with a fair use of AP (45-65mph). A few road long trips on interstates (70+). Have definitely seen some 25-30 mile drives on country roads down around 190 Wh//mi. Not too often, though. Energy consumption is always best when the AC or heat is turned on 10 minutes before morning commute while still plugged in. Always have the AC/heat on auto between 68-70, and always use cabin heat protection.

slingshot18 | 6 novembre 2018

I've been driving a Model S loaner for the past week. It's rated at 259 miles on a 75kwh battery, so about 290wh/mi. With some pretty aggressive driving, and lots of hills on the weekend, I'm at 310wh/mi. That's about a 7% hit based on driving conditions. On my normal commute, the Model S is getting 301wh/mi round trip, which is less than a 4% hit.

In my Model 3, driving very conservatively, trying to maximize range, I get about 300wh/mi. Based on a stated efficiency of around 240 wh/mi, that's a 25% hit!

Either the stated efficiencies are wrong, or something is wrong with my Model 3. I'm convinced of the latter.

And yes, I know not the full 75kwh battery is not 100% usable. I'm ignoring that small difference for this simple comparison.
