Fuel efficiency

Squeeze value out of every kilometre

You’ll have more to spend at your destination if you save on the cost of getting there. Fuel efficient vehicles use less fuel per kilometre, which is better for your wallet and the environment.

Three fuel efficiency factors

  1. 1

    Small is beautiful

    Buy the smallest car that suits your needs – that goes for engine size and its actual dimensions. Just being lighter means it needs less fuel to get moving. It’ll likely cost less to insure as well – use the savings to hire a bigger vehicle if you need it now and then.
  2. 2


    Every year, manufacturers get better at optimising fuel efficiency in the vehicles they make (responding to demand from people like you). They improve engine efficiency and tweak the aerodynamics – and keep making them safer too. So in general older vehicles cost more to run and produce more emissions than newer models.
  3. 3

    Maintenance history

    The less a previous owner spent on their vehicle, the more it’s likely to cost you. A poorly-maintained car can use 10-20% more fuel than a well-maintained one – producing more emissions as it goes. So choose a vehicle with a documented service history or get it checked over by a good mechanic before you buy.

Two-thirds of New Zealand new vehicles are SUVs or utes, which consume much more fuel than a regular car.
