BYD Dolphin Mini or Chevrolet Onix 1.0 (flex) — which comes out cheaper?

As of 1 July 2026: over 5 years in Brazil (12,500 km/year), the BYD Dolphin Mini comes out cheaper — about R$132,353 versus R$139,755 for the Chevrolet Onix 1.0 (flex), a saving of R$7,402. It's at 3 that the electric car moves ahead.

Purchase incentive (consumer): in Brazil there is no direct federal subsidy for a consumer buying a 100% electric car — unlike in Europe. The incentives are industrial: the MOVER program (which replaced Rota 2030 in June 2024) gives automakers an emissions-based IPI tax bonus/malus and R&D credits (~US$ 4,8 bi, i.e. billion, through 2028) — none of it reaches the buyer's pocket. On top of that, the old import-tax exemption for EVs is being phased out, rising to 35% in 2026, which tends to make imported EVs more expensive. We show this separately and include no incentive in the total costs above. Source: MOVER / US ITA / Mobility Portal, as of . Always check the current conditions before you buy.
