Southeast Asia EV Price, Battery and Range Snapshot

Versioned 4 September 2026 snapshot of battery-electric vehicle variants represented in AutoTest Asia's Thailand and Vietnam datasets.

Files

• —southeast_asia_ev_snapshot_2026-09-04.csv: harmonized Thailand and Vietnam table, 195 rows.
• —thailand_ev_snapshot_2026-09-04.csv: 117 Thailand variant rows.
• —vietnam_ev_snapshot_2026-09-04.csv: 78 Vietnam source rows representing 77 normalized model-variant combinations.

What the ratios mean

price_per_advertised_km is purchase price divided by the manufacturer's advertised range for the same variant. It is not electricity cost per kilometre and it is not a real-world range measurement. NEDC, WLTP, WLTC, ECE and manufacturer-defined cycles must not be ranked together.

Thailand includes price_per_kwh only where the published snapshot retained an eligible battery value. Vietnam deliberately leaves that field blank because most battery records did not consistently identify gross, usable or nominal capacity. The Vietnam value_index_score is range-only and is populated only for the selected representative variant within each eligible test cycle.

Provenance

Each row includes an official manufacturer or distributor URL, its check date, an AutoTest model URL and the market-specific methodology page. A URL does not automatically validate every field in the row; users should verify the exact claim against the named source and date.
