Speculation about a return to Mexico for formula one is revving up.
Earlier this year, Sauber sponsor Telmex’s Carlos Slim Domit confirmed that officials are working on a project to end the country’s 20 year absence from the calendar.
On a trip to Mexico in August, FIA president Jean Todt said it is "possible" Mexico will host a race soon.
Slim Domit wrote in a column for FIA in Motion magazine: "Linking races in Canada and the US with a Mexican round would perfectly consolidate formula one’s footprint in North and Central America and provide a viable bridge to the race in Brazil."
Bernie Ecclestone told the Independent newspaper in September: "After Russia I would like to go to South Africa and Mexico.
"Both countries are trying to do something."
Germany’s Speed Week now says "leading representatives" of Mexico’s motor racing federation are "very confident" a F1 race is viable, with the Autodromo Hermanos Rodriguez on pole position as the venue.
That track, in Mexico City, last hosted the grand prix in 1992, won by Nigel Mansell.
