The conclusion I came to was that the centre driveline works at such extreme angles, losses were occurring that my spreadsheet was not compensating for.
I should probably point out that your spreadsheet probably does not take into account a bunch of other variables, but you might already be aware of this. Motors are notorious for not running at their claimed RPMs, batteries might be voltage sagging under load, aero becomes very important at such high speeds. Oh and tyre ballooning is almost impossible to account for. These variables might be the same for your Sworkz and Baja, but not for the Corally.
