GAC Aion UT or Chevrolet Onix Sedan LT (auto): which costs less to own?
As of 1 July 2026, over 5 years in Colombia (12,000 km/year), the Chevrolet Onix Sedan LT (auto) is still the cheaper car to own: about COP 83,808,095 versus COP 100,540,774 for the GAC Aion UT, a gap of COP 16,732,679.
Not a cash rebate — a list-price gap: in Colombia the core EV benefit is structural, at the border. 100% electric cars come in duty-free (0% tariff), while Decreto 1432 de 2025 (MinComercio — the trade ministry's decree of 24-Dec-2025) raised the import tariff on gas and diesel cars from 35% to 40%. That widens the showroom price gap between EVs and ICE cars, but it is not money handed back to the buyer: that's why we model it at $0 and do not deduct it from the total cost above. The effect was immediate (EV sales +171% in Q1 2026, helped also by lower interest rates and Tesla's price war).
