How efficient is it for its size?
Cohort: every currently registered 400–499 L bottom-mount fridge freezer sold in New Zealand, counted once per registration. Star ratings already account for size through the GEMS adjusted-volume formula; this comparison is in raw kWh against models a buyer would actually consider instead.

- 308 L

Gross volumes exclude shelving. Fresh food = fresh food, chill and cellar compartments; frozen = freezer, two-star and ice-making (zero-star) compartments. Adjusted volume weights frozen space more heavily and is what the government uses to set the star rating for the size.
