> The key results: In the first approximately 30,000 kilometres, the loss of capacity is accelerated, and the so-called state of health (soH) drops relatively quickly from 100 to around 95 percent. With increasing mileage, real degradation decreases. According to the Electrive portal, Aviloo data from the 7,000 vehicles showed a (average) SoH of around 90 percent at 100,000 kilometres. According to this, the trendline is almost horizontal, between 200,000 and 300,000 kilometres, it is almost stable – and is well above the 70 to 80 percent of the battery guarantee. In fact, it is rather 87 percent.

Seems pretty consistent with ICE engines, where you can expect roughly a 5-10% loss in efficiency once you get over 100k miles

I don't think I realized that ICE engines had this kind of degradation. What causes this? Seals and parts loosening as they break in? Some loss of efficiency in the fuel mixing/burning process?

Yes. Mainly wear causing loss of compression. So piston rings, valve seals and seats. Also dirt/soot accumulating in air passages, disrupting or eventually blocking air flow, leading to inefficient combustion.
