I would say that,
"J'ai envie d'une nouvelle voiture" would mean,
"I feel like changing my car"
indicating a feeling,
"I need a new car" ( your car has broken down/been involved in an accident) would be,
"J'ai besoin d'/Il me faut une nouvelle voiture"
indicating a strong need,
"I want a new car" is, "je veux/voudrais une nouvelle voiture" closer in meaning to avoir envie de but indicating a wish.
Hope this helps!
Does this sentence also mean 'I want a new car'
