2018 1000km Buenos Aires

The 2018 1000 km Buenos Aires was a motor race for Turismo Carretera held on the weekend of 17–19 August 2018. The event was held at the Autódromo Oscar y Juan Gálvez in Buenos Aires, Argentina and consisted of one race of 1,005 kilometres. It was the ninth round of fifteen in the 2018 Turismo Carretera championship, as well as the eleventh and most recent staging of the 1000 km Buenos Aires.^[1]

As opposed to the 2017 edition of the race, teams were required to enter three drivers per car as opposed to either two or three – one series regular (denoted by a green light inside the car) and two 'guest' co-drivers (denoted by a blue and red light). The grid was determined by the championship standings prior to the event as opposed to a regular qualifying session, however Matías Rossi started from the back due to accumulation of penalties. Following controversy over a two-lap penalty for engine changes the previous year, entries were allowed one 'joker' engine change without penalty. Entries were also allowed to resume their participation in the race if they received outside assistance, which resulted in retirement or exclusion in regular events.

Prior to the race, two changes were made to the entry list. Aldo Ortíz was entered to race for Indecar Racing No. 99, but was injured in a crash in a TC Pista race and was replaced with Junior Solmi. Santiago Andreoli was also injured in a crash in TC Pista, and his UR Racing No. 44 crew were allowed to compete with only two drivers as they failed to source a replacement driver.

Julia Ballario, competing for Neuquén Energía No. 33, was the only female driver in the field.
