I’ve got similar wh/m on my 2018 PD3+ (with the 20” wheels, big brakes, etc), so it’s good to know my efficiency isn’t that bad comparatively.

Makes me feel better - Just picked up my M3P and was thinking my numbers seemed high from what I've read online. 351 Wh/mi here with 450 miles on the odometer.if you aren't in the mid 300s, you are driving it wrong...

Not slow. Probably close to what you do with bursts above. Pretty heavy on acceleration too. What wheels did you swap to? That's the one thing outside of a bit of tint that I want to do with the car.How do you drive? i was around 350 wh/mi when i first got it because I was driving pretty fast I also drove 80-85mph on highway consistently. My first 20k miles was about 340 wh/mi average. I switched to 18 inch wheels and dropped down to around 300 wh/mi consistently (PS4S).
NM Heat. Texas heat is similar or worse. All windows (plus windshield with LLUMAR AIR 80) with LLumar IRX ceramic tint on the doors and back. Get sunshades for the roof glass - as doing all of them helps reduce cabin heat drastically (windshield tint reduces dashboard heat, which keeps the air coming out of the vents cold) and energy to keep the ac going. With all windows tinted and roof shades - it's a night and day difference. Plus - install new air cabin filters once a year too.My average wh/mI has been decreasing with the cooling weather and my new roof shades… down to about 335 wh/mi (from 350).

Pretty sure the aerodynamicists on the planet would disagree with you that micro surface roughness makes any difference to aero drag at 70 MPH on a non-laminar shape like a car.Helps to have a slick and clean car for aero efficiency - use a spray on ceramic coating + rainX after each wash.
This is equally dubious from a physics standpoint.My tinter said that the model Y's regardless of tint run hotter inside, due to the more volume of space to cool.

Too bad Mythbusters isn't still on to test this. They did demonstrate that the exact reverse is true however:

Geez. The last owner drove it wrong….2020 M3P 50,223 miles lifetime average 263 Wh/mi
Bought 1 1/2 months ago, I thought the consumption was high but seems it's actually not that bad lol
20" ps4s

I guess Adrian Newey (Red Bull chief designer and aero principle) should dimple the F1 car and pour mud over it to make it more aero efficient? Nonsense, a slick vehicle will enable the aero design to maximize the efficiency flow. Last step in increasing your car's aerodynamics after reducing weight you have to move and design, you can thoroughly polish the vehicle's exterior to make that as smooth as possible. A car with a smooth outside surface provides less resistance to air traveling over and around it, lowering drag to a point.Pretty sure the aerodynamicists on the planet would disagree with you that micro surface roughness makes any difference to aero drag at 70 MPH on a non-laminar shape like a car.

I think a lot of this stuff depends on the shape of the car and the speed regime its made to operate in. Dimples can be used to trip up laminar flow to create vorticies which energize the boundary layer and keep flow attached to a surface, but there's a lot of calculation into where and how big those dimples should be. F1 cars tend to use vortex generators (see Ferrari's new front wing this weekend ---- not that Ferrari has been a prime example of performance in F1 lately ).I guess Adrian Newey (Red Bull chief designer and aero principle) should dimple the F1 car and pour mud over it to make it more aero efficient?

Cooling - less cubic feet to cool and surface greenhouse glass - the cooler you will keep the space. Presuming the M3 and MY have the same heat pump systems in terms of size for cooling and overall insultaion - Y has much more volume to cool. Seat to the pants driving both of them in the summer Texas heat will tell you there is a difference.
There's no REAL lifetime... Many people use Trip B and never reset it so its effectively the lifetime (I renamed my trip B - "L:fietime")How do you find lifetime? I only see current and since last charged.
I should have done the same thing. That’s a great idea.There's no REAL lifetime... Many people use Trip B and never reset it so its effectively the lifetime (I renamed my trip B - "L:fietime")
