you are comparing a vehicle with a 106.3 vs 80.7kw (usuale range since BMW doesn't allow for 100% battery capacity) battery pack in terms of range.
iX = 3.048 miles/kwh
I4 M50 = 3.346 miles/kwh
**EDIT** looks like someone posted it already lol
But in terms of .cd drag, the iX50 and the i4 M50 have the same .25 cd of drag. The biggest differences are larger frontal area and more weight of the iX making the largest impact.
But yes, if the i4 had a dedicated EV platform, it could perform better. However, as is, the i4 edrive40 and M50's are pretty efficient, not even using the "despite using an ICE" platform. It's not the most efficient obviously, however it's definintely not terrible.
Also keep in mind that EPA testing weighs more on highway driving. Actual range will likely be between EPA's 270 mile range and the WLPT cycle of 317 miles (which favors more city driving). Additionally, many German vehicles are underrated using the EPA cycle as well (MB and Porsche come to mind). BMW is a conservative company, something to keep in mind.
