A private consortium purchased the Buenos Aires track in 1991, renamed it and began to upgrade it. They secured a place on the 1994 F1 season calendar, but the race (set for October) was aborted to continue modernization. The general layout was not changed, but an "S" chicane named after Ayrton Senna was added. The No. 6 arena circuit was used, which did not include the flat-out lake run. This tight, twisty circuit was not well suited to Formula One cars and it was very difficult to pass on this variant because of the corners being so close together. The modernized Argentine Grand Prix returned in , with victory going to Damon Hill. Hill won the event again in (his championship season), and in Jacques Villeneuve won the race in his championship season.
