Autódromo Oscar and Juan Gálvez Long – Buenos Aires 

When was the track built?

Built in 1952, after the city hosted several road course Grand Prix, exploiting the big popularity of motorsports thanks also to the success of Argentinian drivers like Fangio and Gonzales, it is the only circuit in the nation which has hosted a Formula 1 Grand Prix in the 50s, 70s and mid-90s, in various layouts.
Due to the national financial struggles Formula 1 never came back, but in 2025 Tilke and the MotoGP redesigned a single-layout main track that will be suitable for all main motorsport categories, with completely new facilities.
The new F1 Organization will keep the old loop for a second variant, that would be suitable also for endurance racing.

When was its first Grand Prix?

In 1953, on the circuit 2 variant; a race dominated by the Ferraris of Ascari, who won from pole, and Villoresi, while one of the local heroes Gonzales managed to take third on his Maserati; Fangio retired while he was in second place.
On the 15S layout, the first race was held in in 1974, the inaugural event of the season; Denny Hulme on McLaren-Ford won a rip-roaring one, after several drivers were forced to retire, including pole-sitter Ronnie Peterson, his Lotus teammate Jackie Ickx and fan favorite Carlos Reutemann on Brabham-Ford, who was leading up to the penultimate lap; Lauda and Regazzoni completed the podium for Ferrari.
It is one of the eight Argentinian circuits in the database that will rotate for three spots in the Continental Series and one in the World Title.

What’s the circuit like?

The modified Long layout uses the first five corners of the new MotoGP layout, which guarantee a good flow, that lead to the old lake loop section.
An 800m long straight ends in the tight chicane T6-T7 followed by a long newly banked T9 that launches cars into a 1.1km straight.
The tight hairpin at T10, one of the several and best overtaking spots, brings drivers onto the small bridge that climbs the lake and reconnecting to the MotoGP layout from T12 to T19, with again a nice technical flow.
The final hairpin is moved further away from the exit of the Arena, allowing for another 1km long straight, before the final easy bend at T21.
This variant keeps the old-school feel while offering modern facilities, several overtaking spots and high average speeds.
Cars will have ultra-low drag set-ups and engine power will play a part on this track.
