What Wh/mi are you getting with AWD and P cars?

[CarpetMan]

Getting a pretty bad 340-370 Wh/mi efficiency on a new P3D+ with no mods when going 75mph on highway, 45F. Surprised by this. At this rate the snow tires should get much better efficiency. I wonder if it's just the tires.

Lowest average I've gotten is 284 Wh/mi on a lower-speed (~60mph) drive, so it doesn't seem like an outright mechanical issue.

I was in the same boat as you (AWD 19” rims, but non performance).
I was averaging 342 wh/mile until I hit over 500 miles. Seems to be some kind of a break in period. I’m guessing it’s the tires.

Once I hit 500 miles I drove 100 miles on the interstate at 75 mph with 260 wh/mile. Also at 55 degrees I’m seeing really good efficiency, at 45 degrees I see a huge spike in consumption.

My lifetime efficiency is 286 wh/mile. On local runs today I got 254 wh/mile which is about what my LEAF is getting.

I thought M3 would do better than the LEAF, here's hoping the inefficiency is new tires. Only have 250 miles total so far.

It's speed and tires. I just did 250 miles this weekend (mostly 65 mph), temp between 28-50F, Limited Regen for about 90 miles of that 250.

I got 250 Wh/mi

P3D- with 18" X-Ice tires on. Aero covers on.

238 Wh/mi on Lifetime @ 1600 miles.

We drove our new model 3 LR/AWD 19" wheels home escorted by my model S85 leading the way.

The 3 was locked on TACC (set @3) behind the S and we cruised at 110km/h for hundreds of kilometers.

So this is a perfect side by side test... same route, conditions, speed, etc.. both on cruise.
Model S low regen whereas the 3 used standard regen...
Model S at 45psi all around, the 3 was at 42psi all around.
Model S, no HVAC, whereas model 3 used auto HVAC setting around 20C
Ambient outdoor temp was about 16C so HVAC not working too hard if at all

The trip is not too undulating open highway cruising.

Model 3 might have even had advantageous position behind the S, if there was any drafting benefit to be gained but doubtful.

We both set battery display to %

Throughout the trip we compared % remaining and % estimate at destination, our home.

Pretty much BANG ON EQUAL.

Actually, to our disappointment. We had hoped and thought for sure the 3 would do quite a bit better out of the box for equal driving styles. Nope. Given, if HVAC was off we'd expect the 3 would have done better than S on the same trip, but probably around 10% at most. Even that is not impressive.

We think the biggest downer is not having 18" wheels and aero covers. What would we stand to gain with that, another 10% maybe ?? 40 to 50 km extra range per charge?

18" Aero's with covers would definitely help. Also give your 3 at least a few 100 miles to break in. I really wanted to put 19" wheels but after reading all the data I stuck with 18" Aero's with covers. I'm glad I did because there are so many ways to lose range I figured why give up range that you DO have control over.

So what is "equal" as in what was the wh/mi?

There was a nice spread sheet/grid posted (might have been this thread). That gives all the numbers. I think some of it is based on data and some interpreted. Not sure. But it seemed pretty accurate.

We don't have Wh/mi where I live

I didn't record the number of Wh/km for each car... sorry

The point of my post was more of a real world data point of distance-per-capacity of two different car architectures. Not efficiency. I shouldn't really have posted in this thread, I just thought it was an interesting head-to-head of two different architectures under a nearly ideal and fair competition.

Taking the battery size out of the equation. Charge percent is relative to each car itself... and only itself.

I think the model 3 has a smaller battery but eeks more out of it when translated to amount of ground moved under the wheels. So yes, the 3 is more efficient. Easier on the pocket book for energy. But doesn't go remarkably further than the bigger tanked and less efficient model S.

I offered to my wife that we'll buy a set of aero's and slap them on if we actually need the max possible range for the car. We'd have 3 sets of wheels then: stylish 19s, good winters, and aero's. Storage space at home and ability to change my own wheels with air tools helps.

I'm at about 1400 miles so that shouldn't be an issue. I really think it's the wheels/tires (PS 4S tires are sticky). Switching over to 18" wheels soon for winter (no aeros for P3D+ unfortunately) so we'll see how that goes.

Lifetime efficiency is 380 Wh/mi, but some of that was track usage

 

[Oyinko]

Would pumping the pressure from 41 PSI to 45 PSI on the PD3+ help with the range? Might do that only for the long trip.

 

[Vines]

P3D+ here and I am getting a lifetime of just dead on 300 wh/mi.

I don't baby it at all, just drive normal with some badass acceleration whenever I need a jolt of adrenaline. Most of my freeway 98%+ is with AP engaged, set to 80 though its usually more like 70-75 because of traffic.

 

[Thomas Edison]

I was at 314 with covers on my daily commute and decided to take them off, now I’m at 320. It’s 33 miles round trip with back country roads first half, stop and go in town for the remainder.

 

[Kmelnuk]

Picked up our Model 3 AWD last week with 18” aero wheels. As a former Model S P90DL owner, I’ve been thrilled with efficiency on Model 3.

Did one trip 200 miles round trip in Florida (86 F) at 75-79mph the remaining miles are strictly city driving under 30-50mph.

Normal driving I can easily obtain 220 wh/mi.

 

[Iroh]

I'm at currently at 290Wh/mi for the 2058 total miles driven.
I mostly attribute this high Wh/mi rate to my wife's daily commute; driving with low regen and the tollway she uses where speed limit is 80mph - 85 in some sections.

I drive with standard regen and yesterday's~200 mile trip has me wondering what am I doing wrong and how i can get better Wh/mi.

I charged above 70% for the first time for a ~200 mile round trip.
Drove on EAP 95% of the trip with speeds no more than 70mph on short occasions and staying between 55-65mph for the majority of the trip.
Outside temps were between 47-51F, inside temp was between 72-74F while driving.
I don't remember the inside temp while the car was parked for 3.5hrs - cabin overheat protection is set to fan only.

"Since Last Charge" details
195.6 miles
57 kWh
293 Wh/mi

Left home with 97%, got back at 18%.

AWD. Over the last 3 weeks 380 Wh/mi. Conditions have been mostly Snow/ice covered roads, temps in the 10’s-low 30’sF. 18” aero’s with nokian Hakka 9’s.

 

[chrisbac]

I have a 2 week old M3 AWD. SO far 895 miles. Still always getting 330+ Wh/mi. I took a trip, 80 miles each way using Autopilot. Had a reported 305 Mi range and had to stop for charging before I got home (at least the car was complaining a lot telling me I would not make it). This worries me a lot as it is not even close. How can you have to supercharge on a 160mi round trip with 305 mile charge? It was moderately cold, ~50F, for this trip.

 

[Snow Drift]

AWD on stock 18s, from Sept to Nov, a mix of highway and local driving...

 

[coleAK]

Here is what I’m getting with my daily commute. The peaks are the house.

 

[MacGreiner]

260 Wh/mi for me. 3k miles in. 18s with aero covers. Don't go over 70 mph on freeways.

 

[Ciditad]

My commute is mix of highway and local. Been getting 233wh/mile.

Be nice if folks could include Wheels, Wheels Driven, Cruising Speed and Average Temps.

Without that, your numbers could be horrible, average or amazing
