Even on a long journey at a steady 70-75mph it returned 2.9m/KW.

What exactly have BMW changed?

There is probably different battery management software for the i4 vs the i5. There was a rumour about the i4 getting the i5 system with the bump in horsepower for 2026 model year,

Out of your i4M50?

Today I did an efficient mode experiment in my i5 M60. I drove 7 miles to Cycle Barn and 7 miles back home. Mainly downhill in one direction, I got 4.2 mi/kWh. Uphill heading home, I got 3.5mi/kWh. I did max efficiency as it was a high of 57 and didn’t need the heat or the A/C. My car was at 58% battery and it said I had 204 miles of range. Other than sluggish acceleration, it seemed worth using for local trips with a 30mph speed limit. I even let the car drive itself part of the way.

I should probably try this out for one of my local trips to the tennis courts. I drive this route 2-3 times per week and it's about a 10 mile trip each way. The max speed limit for much of it is 50 mph. Typically, in Personal mode I average about 3.3 - 3.4 mi/kWh.

Your test has inspired me! I will try it this coming week and see how it does on a 50 mph limit trip.

In heavy traffic on my way to work or home here in VA, I’ve used max range mode when weather permits and it’s not too hot. It’s great and makes my efficiency much better.
