All three teams spent their final night on the road camped close to Port Augusta, in SA's mid-north.
Vattenfall's likely victory will be bittersweet though after Solar Team Twente crashed out of the lead and on Wednesday.
The team's RED E car flipped north of Coober Pedy as strong winds battered the field.

The deteriorating weather conditions also claimed the German Sonnenwagen team when their car was damaged after it was forced off the road by wind gusts. Its driver was also unhurt.
