Sources & how to compare

  • Prices are list prices before on-road costs; editions and option packages are not separate powertrain variants.
  • Fuel-use badges compare non-plug-in combined petrol figures only. PHEV consumption depends on charge state; the BMW figure is WLTP weighted, while the GLA 250 e's published 1.2 L/100 km figure has no cycle identified in the cited source. PHEVs are not ranked against petrol-only models.
  • †GLA rear legroom comes from 2026 Mercedes-Benz North American cabin dimensions; ‡BMW rear legroom is from CarExpert’s specification data. These are indicative, not a common Australian measurement standard. Audi’s Australian material does not give a comparable mm figure.
  • Dimensions are length × body width (excluding mirrors) × height; wheelbase is shown separately. Published GLA/Q3 dimensions vary slightly between databases and measurement conventions; confirm with the manufacturer.
  • No Q3 PHEV or separate BMW iX1 is included in the model/variant scope. Confirm current availability and specifications with the manufacturer before purchase.
