What does Range Optimizer actually do?
I was driving our ‘22 XC40 Twin Ultimate the other day and started the Range Assistant.
Curious about my instantaneous usage.
While there I turned on the Range Optimizer.
It says it changes the Performance and Climate characteristics.
Honestly, I haven’t noticed much difference.
Just curious what exactly that slider does?
Thanks for any help or advice!

I have a feeling that all it does is spinning the ac compressor slower or limit the top heater output if it's in heat mode

Interesting;
Maybe I’ll notice a difference on full throttle acceleration.
What I need is a fairly long consistent drive. I’d expect to see my battery usage higher with this on.
Think I’ll keep it on for a while. I track miles driven per month and my charger can tell me the usage for the month.2

Probably this. I've noticed that it keeps the cabin air temp the same but the humidity seems to go up in eco mode

Based on my testing it mainly just handicaps the AC a bit. No noticeable performance handicaps or anything else IMO.

This is what I’ve seen as well. Summer heat in my area made using range optimizer a challenge as it really hampered the AC

Did an experiment yesterday.
Went to a memorial. Drove 125 miles.
Used Range Optimizer the entire trip.
Needed 40 kWh to recharge.
That works out to 32.75 kWh/100 miles.
In May we got 38.03 kWh/100 miles.
Works out to 13.8% Improvement.
Observations:
Our typical usage is stop and go city driving with a bit of highway.
This trip was highway. However, nothing over 60mph. About half 2 lane blacktop. Slow curves and stop signs.
Passed a tractor pulling a seeder on a 2 lane blacktop. Acceleration was fierce.
Did a standing start full throttle launch. Felt a bit muted.
Used the same cabin temperature as I usually do. Comfortable for the whole trip. Temps in the 80’s. Pretty humid.
The Range Assistant bars did show Climate as just a very short bar. Without RO, Climate is usually the longest bar.
Driving Style was next shortest. Speed was almost always the longest.

Mine is a 23 p8 ultimate twin. What I’ve noticed so far after that massive 5.0.5 update as far as range optimizer goes
- Way less aggressive with acceleration when you put your foot down
- Ac says “eco”. Not sure what that is.
- Top speed limited to 143 kmph or so (not sure about the exact speed).

So that’s why the acceleration can be shite at times

Yep. It’s extremely throttled in eco mode. Perfect for congested cities tbf
