Methodology
Cars are compared on manufacturer-rated maximum power and torque, certified fuel economy (km/L, converted from each market's test cycle: EPA, WLTP, CLTC, JC08/WLTC, ARAI) or EV energy use (kWh/100km), official NCAP crash-test ratings from the model's home-market programme, and list prices converted to USD at recent exchange rates. Each model shows its newest listed year and its highest-priority market trim. Test cycles differ between regions, so cross-market economy figures are directional rather than exact; prices exclude local taxes and incentives.
