The driving distance is approximately 2,170 km to 2,240 km. Fuel costs are estimates based on average prices in Brazil (BRL 5.50-7.00/liter) and Argentina (ARS 1300-1700/liter, converted to BRL, noting high ARS volatility). Tolls are prevalent in both countries and can be paid in local currency (cash or card) or via electronic systems (e.g., Sem Parar in Brazil, TelePASE in Argentina). An International Driving Permit (IDP) is recommended in addition to your national license, and vehicle documentation (registration, insurance) is essential for border crossings.
