You need to compare apples with apples, one is a slippery saloon, the other is a large SUV, with +350kg to deal with.The Tesla M3 is VERY efficient. I don't think that gets noted enough in the various road tests. Some competitors just pile in batteries to get range. The Jaguar iPace for example achieves 2 - 2.5m per kWH. Compare that with the 5 miles/kWH in your figures above.
