Almost every corner on the Autodromo Hermanos Rodriguez will be altered to accommodate Formula One when it returns to the venue for the 2015 Mexican Grand Prix.
A promotional video issued by the federal district reveals how the circuit, which was first used for F1 over 50 years ago, will be revised to bring it into line with modern safety standards.
The sweeping three-turn chicane which opens the lap of the clockwise circuit will be tightened. The next sequence of corners – turns four, five and six – will also be tightened and slowed, giving more space for run-off.
The challenging, high-speed Esses in the middle of the lap will be altered in parts and also benefit from increased run-off space. But they should remain one of the quickest sections of the circuit.
However the once-fearsome Peraltada corner will not be retained in the configuration it was when F1 last raced at the circuit in 1992. The circuit will turn right into a baseball stadium in the centre of the corner, and rejoin the old track via a hairpin and two right-handers.
The high-speed nature of the 180-degree bend, and the inability to make safety improvements to it due to a public road which runs behind it, forced other single-seater series which have visited the track since F1 left to make changes. The now-defunct Champ Car and A1 Grand Prix championships last raced at the venue in 2007 and 2008 respectively, each time using a slow chicane before the corner:
