Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Benchmark anchor. The score uses the 30 kW highest model in the exact Australian family. Scored model: X3-ULT-30K · checked 2026-08-02. Evidence.

Strong evidence coverage

24 of 24 scored criteria link directly to a published source.

Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.
