Background

The 2017 1000km Buenos Aires was the first staging of the race as a Turismo Carretera event, but wasn't the first multi-driver enduro in the modern era of Turismo Carretera – a 500km race held at the Autódromo Hermanos Emiliozzi the previous year, won by Matías Rossi and Esteban Guerrieri, was the first since 1996. Similar to Supercars Championships' endurance driver rules since 2010, the regular season drivers could not partner up and had to be joined by one or two 'guest' co-drivers. Regular drivers were denoted by a green light inside the car, with the first guest denoted by a blue light and the second guest by a red light.

The race was held over 178 laps (1,005km), but had a time-certain limit of 6 hours. Outside assistance rules were relaxed for the event in that entries could resume participation in the race if they received it, but penalties for technical changes were heavily tightened – entries would receive a 1-lap penalty for changing a cylinder or engine cover, and a 2-lap penalty for changing an entire engine. The grid was set by the championship standings order prior to the event, however Mariano Werner started from the back of the grid for accumulation of penalties as did cars #7, #8 and #31 for taking engine penalties.

Race

Despite being spun by Gastón Mazzacane inside the first ten laps, Juan Manuel Silva and Juan Tomás Catalán Magni emerged the winners of the 1000km Buenos Aires having taken the lead after the last pit-stop cycle. Guillermo Ortelli – whose co-driver Diego Martínez both suffered a high-speed spin mid-race and earned the team a 20-second post-race time-penalty for not changing the co-driver light – inherited second late in the race after both long-time leader Mariano Werner's co-driver Juan Ronconi retired with an oil leak five laps from the end, and Juan Martín Trucco's (who completed the first four-and-a-quarter hours of the race by himself) co-driver Elio Craparo broke down three laps from the finish; although it was likely that the #1 Chevrolet would have scored a podium regardless having finished with strong late-race pace. Juan Marcos Angelini finished third on the road, but received a 2-lap penalty for an engine change and elevated José Manuel Urcera – who had completed the whole race on the same set of tyres – to the podium. Facundo Ardusso was classified fourth, and ultimately the last car on the lead lap as Esteban Gini was penalised 3 laps for not completing the mandatory number of driver changes.
