Energy efficiency in ACC?

[Ian 2455]

Update...
Just returned from Wales using only my right foot to moderate the power. Arrived with 31% SOC and showing 85 miles of remaining range. Weather was 8-14 ° but very windy. Even including an 8-10 mile detour on the outward journey, that is a significant gain.
My verdict...humans are more efficient than the version of ACC on a 2024 MG ZS LR.
Would this convince me to never use ACC...no, but I do not feel it will ever be my default option. I do strongly feel that those little incremental gains from region during the journey do add up though.

That's interesting Ian. I've found the opposite, but it will vary per journey depending on road type, length of journey, traffic conditions, terrain etc. Interesting to hear your thoughts.

And the best indicator was the efficiency...3.3 miles per kWh outward and 3.7on the return...

My efficiency showed an improvement of 0.3 miles per kWh WHEN USING ACC. But going the other way against the wind might have shown the opposite. Coming back I didn't use ACC because I came back a completely different way going cross country on back roads where using ACC wasn't really a good idea.
