Eco-friendly vehicle part contains uranium, really oddly (6-7)

'uranium really oddly' is the definition.
I can't judge whether this definition defines the answer.

'eco-friendly vehicle part' is the wordplay.
I cannot really see how this works, but
'vehicle' could be 'car' (car is a kind of vehicle) and 'car' is located in the answer.
'part' could be 'ut' (ut is a kind of part) and 'ut' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

'contains' acts as a link.

Can you help me to learn more?
