Drive to the outback, in open country (5)

I believe the answer is:

motor

I'm a little stuck... Click here to teach me more about this clue!

'drive' is the definition.
(synonyms)

'to the outback in open country' is the wordplay.
I cannot quite see how this works, but
'to' is found in the answer.
The remaining letters 'mor' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for motor that I've seen before include "Car; travel quickly" , "Engine - relating to movement" , "Car (colloq,)" , "Engine of vehicle" , "Car; powered machine" .)
