Autódromo Termas de Río Hondo is a motorsport circuit located in Termas de Río Hondo, Argentina.
 The circuit was created in 2007 and underwent a complete overhaul and rebuild process in 2012, based on design by the Italian circuit designer Jarno Zaffelli.
 The circuit hosted the third round of the Argentine motorcycle Grand Prix in 2014 and 2015, bringing Grand Prix motorcycle racing back to Argentina after fifteen years.
 In 2013, the circuit also hosted Rounds 15 and 16 of the FIA WTCC Race of Argentina of the World Touring Car Championship, and the first MotoGP and Moto2 official tests.
 The track was to host the Argentine motorcycle Grand Prix in 2013, but the government's nationalisation of the local subsidiary of Repsol S.A., and the ensuing cancellation of gas exports to Argentina raised concerns for the safety of the Honda MotoGP team that is sponsored by the Spanish oil company, forcing a one-year postponement.
 In previous years, the circuit has also hosted events in the TC2000, Turismo Carretera and Formula Renault series.
The 1976 Brazilian Grand Prix was a Formula One motor race held at Interlagos in São Paulo, Brazil on 25 January 1976.

The 1990 Brazilian Grand Prix was a Formula One motor race held on 25 March 1990 at Interlagos.
 It was the 19th Brazilian Grand Prix and the ninth to be held at Interlagos.
 The São Paulo circuit had not held the Grand Prix since 1980 and the circuit was extensively renovated with the circuit itself almost halved in length.
 The race was contested over 71 laps of the four kilometre circuit (as opposed to 40 for the races on the original circuit), for a race distance of 307 kilometres.
The Autódromo Internacional Nelson Piquet (Nelson Piquet International Autodrome), also known as Jacarepaguá after the neighbourhood in which it was located, was a motorsport circuit in Rio de Janeiro, Brazil.
 Opened in 1977, it hosted the Formula One Brazilian Grand Prix on ten occasions, and was also used for CART, motorcycle racing and stock car racing.
 In 2012, it was demolished to make way for facilities to be used in the 2016 Summer Olympics.
Autódromo José Carlos Pace, also known by its former name Interlagos, is a motorsport circuit located in the city of São Paulo, in the neighborhood of Interlagos, renamed after Carlos Pace, a Brazilian Formula One driver who had died in a 1977 plane crash.
 It is well known for being the venue of the Formula One Brazilian Grand Prix.

 It was race 2 of 14 in both the 1975 World Championship of Drivers and the 1975 International Cup for Formula One Manufacturers.
 It was the fourth Brazilian Grand Prix since its introduction in 1972.
 The race was won by São Paulo native Carlos Pace driving a Brabham BT44B.
 It was the only win of Pace's career; he was killed in an aircraft accident two years later.
 The circuit now holds his name.
 It would be eight years before another Brazilian would win the Grand Prix.
 Fellow Brazilian Emerson Fittipaldi finished second in his McLaren M23 with his German team mate Jochen Mass finishing third.
The 1980 Brazilian Grand Prix was a Formula One motor race held on 27 January 1980 at the Interlagos circuit in the Interlagos neighborhood of São Paulo.
 It was the second round of the 1980 Formula One season, and it was also the ninth Brazilian Grand Prix.
 It was the eighth to be held at Interlagos and would be the last until the circuit was substantially redeveloped for the 1990 Brazilian Grand Prix.
 The race was held over 40 laps of the 7.87-kilometre circuit for a total race distance of 315 kilometres.
 This race was originally supposed to be held at the Jacarepaguá circuit in Rio de Janeiro, but was transferred to Interlagos because parts of the Rio circuit's tarmac were actually sinking into the soft swampland the circuit was built on.
 This last-minute switch to Interlagos- which was to be resurfaced and heavily rebuilt with new pit facilities and safety measures for the 1981 season caused a lot of controversy- Interlagos had returned a bit too soon for some of the drivers.
