Anyone notice Wh/mi increase after uncorking?

[AlgaeHater]

I recently had my MX 75D uncorked. As expected, my Wh/mi spiked shortly afterwards as I was "testing" the increase in acceleration. However, I've noticed that my consumption has increased from ~350 Wh/mi to ~390 Wh/mi driving the same roads at the same speeds. Has anyone else noticed this? It is getting a bit colder and wetter here in the PNW so perhaps the weather is the main contributing factor?

Has anyone tested their consumption after uncorking and compared it to pre-uncorked numbers?

I’ve done a few thousand kilometres since uncorking and my usage hasn’t changed.
Was 197Wh/km historically (40,000kms) and since uncork has been 198Wh/km.

Good know. Mine is scheduled for Monday. Was the performance increase noticeable?

My consumption went up a similar amount the past few days. No change in car, but avg temp dropped 15 degrees.

I thought my consumption improved after the "uncorking". I don't find it is faster the first few feet, but definitely continues to build speed a bit longer and lifts the front end.

I'm guessing that the uncork didn't work then, you'll definitely notice a huge power increase from zero (or from anything up to 50mph).

Did you control for weather? Cold snap across the plains and Midwest jacked my highway average from 290 to 360 — with no uncorking.

Mileage might change if you accelerate more ... Updated 100D Performance tests and Chill Mode

I noticed this as well. I’m still not sure I’ve had a successful uncork, but the SC confirms I have.

I chalked it up to the colder weather but it’s not unreasonable to expect this change would result in higher wh/mi.

Oh yes, it’s way more powerful. Almost brutal. I certainly no longer envy the P cars.

It can only be a combination of weather and acceleration. You have more power available, but if really not using it then your efficiency is unchanged. I expect you are accelerating a little faster even if you don't notice after a while. I find that with performance increases, you quite quickly re-calibrate your brain until it becomes the norm.

I just got mine uncorked today and I'm going to go back to the SC and ask them for a P badge to put in front of my 75D. The acceleration is phenomenal, it's like a mini-ludicrous mode! The higher acceleration will produce higher power consumption but when driven normally my consumption was the same as before. I encourage everyone who is eligible to get this done. The performance upgrade will literally floor you!

How are you guys getting such crazy low WH/km?? My overall average since buying the car is 253 Wh/km....

In the Summer days I'm usually getting 250....currently I'm getting around 300-350 WH/km...


Speeds *in theory* might have been....130km/hr - 150km/hr on the highways.

- Pretty slow driving (Australia has an annoyingly low max speed limit of 110kph, and very diligent police)
- 19" tyres
- Mild weather, rarely lower than 10C, usually in the 20s.

That could be it....PS: if you think 110kph is mild....Canadian limits are 100....at 150km/hr we get the following gift:
1) $10,000 fine
2) Road side impound
3) 30 day license suspension

I have the standard 20" tires....

Temperatures play a factor, but very rarely have I been able to get anything lower than 220-230 even with the "perfect weather" where neither AC nor heat is required.

Firstly, ouch! That's a big fine. Having said that, I think 50kph over would be pretty brutal here too.

However, the big difference is that you're in a Model X! I'm in an S. The SUV shape has more drag, that will be the major difference.

Ahh that explains a lot actually! I didn't realize you were driving an S
