It did not help them at the X Prize did it. |
Well actually it did help.
It did improve stability.
Stability was part of the competition.
Help yes ... compensate for all other Aptera deficiencies compared to all other x-prize competitors in all other parts of the competition , no.

Perhaps.
'ENOUGH' depends on the context / conditions , and criteria of what is 'ENOUGH'.
I'm not them so I can't know for certainty ... but perhaps that is why it was originally designed to have the comparatively lighter motor in the rear as a rear wheel drive to keep the comparatively heavier battery component in the more forward position... but the new company management wanted it done differently ... good or bad , they pulled rank , and ordered the redesign.
Of course 2 tire front wheel drive pulls out / handles significantly differently than a one rear wheel drive pushes / handles ... which is another reason I think the choice to change has pros and cons.
