Hyundai Kona tops Brazil hybrid fuel‑efficiency ranking as BYD offers lower‑cost EVs

In a 2026 Inmetro test, the Hyundai Kona HEV recorded the highest average fuel consumption at 17.2 km / L (18.4 km / L in the city), edging out the Honda Civic Hybrid, Kia Niro, Toyota Yaris Cross and Toyota Corolla by just 0.05 km / L. The ranking, which measures hybrid‑only (HEV) models that do not need external charging, highlights the Kona’s efficient use of its electric motor at low speeds.

A separate cost analysis of Brazilian‑market vehicles shows BYD’s fully electric models (Dolphin Mini GS, Dolphin GS, Yuan Pro GS) incur monthly maintenance expenses ranging from R$ 868 to R$ 1,131, well below the R$ 1,600 + monthly costs of Toyota hybrids such as the Corolla Cross XRX and Corolla Altis Premium. Energy costs also favor BYD, with annual electricity bills of R$ 688–R$ 875 versus Toyota’s fuel expenses of roughly R$ 6,000 per year. While BYD’s EVs are cheaper to run, the top‑ranking hybrids remain attractive for drivers seeking maximum fuel efficiency without relying on charging infrastructure.
