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.

"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.
