I’m confused. Just took 1st long trip with my new i4. Departed with 180 mile range and 78% battery capacity. Drove 93 miles. Ended with 130 mile range and 44% remaining capacity. Does this make sense?did i regenerate 40 miles?i drove entirely in B mode.

I think this is expected due to different efficiencies in driving just like an ICE car. Range can be affected by several factors like stop/go vs free flow traffic and hills vs flat terrain. I think the range estimate on the i4 is based on most recent driving.

If I’m going on a longer drive I plug in the route to myBMW app and/or in car navigation and it’s always been accurate within a few percent since it knows what kind of driving to expect.

After awhile I got a feel for how much range to expect around town vs longer trips just like I have with my ICE vehicles. Had the i4 for almost a year now and love it.

Your range is constantly being recalculated based upon recent driving conditions and habits. Over time you’ll likely get a feel for that, but would recommend a combination of tracking %state of charge and efficiency (miles/kWh) as a good way to track your efficiency and range

As noted above, the range is not static and is constantly being recalculated based on many factors - ambient temperature, driving style, terrain, air conditioning/heater use, etc. etc.

Totally makes sense. In B mode, the i4 uses aggressive regenerative braking, which feeds energy back into the battery every time you slow down.

So even though you drove 93 miles, regen could’ve added enough juice to appear like you only lost 50 miles of range. The range estimate is dynamic too, based on your driving style and terrain, so it’s not a precise 1:1 ratio with battery %
