Can I trust the displayed battery data?

Your profile says you have an SE SR ... that's the 51kWh version (50.8kWh usable - allegedly). The 64kWh version is the SE LR (or Trophy LR).

Indeed, and pretty much identical to the figures my SE trots out regardless.
10% optimistic even if you ran it to zero, 20% optimistic if you leave a sensible buffer.

I think these factory range defaults are so no one is scared off during a test drive. Pity they couldn't have an adjustable range 'slider' hidden in the touchscreen menus to help you match the reality.
