The Honda Accord driver, without major backing from the Japanese firm, beat the might of the works team around the new Mexican circuit.
The Italian said: "The car is really good and I'm confident on the new track. Nobody has tested so we have the same advantage as everybody else. It was really good for the team. Everything went in the right way."
SEAT's Peter Terting will start alongside Colciago on the front row. The German was revelling in the advantage the front-wheel drive cars appear to have. "This circuit is not bad for SEAT because there aren't any long straights, its just one corner after another," Terting said.
Fabrizio Giovanardi was the top Alfa Romeo driver after qualifying third alongside teammate Augusto Farfus Jr.
The session was a nightmare for the rear-wheel drive BMW's with Championship contenders Andy Priaulx and Drik Muller qualifying 15th and 16th respectively. The flowing nature of the circuit suited the front wheel drive cars, and the pair will be up against it to score points tomorrow.
The new circuit took its toll on many runners, after a spate of accidents during qualifying that brought out the red flag three times. The WTCC uses Puebla oval's road course layout and the run off areas on some corners are limited.
SEAT's Jordi Gene brought out the first after an accident with Alfa Romeo's Gabriele Tarquini. Gene tried to drive round the outside of the Italian, but appeared to slide into him, launching himself into the air and across into the mud on the outside of the circuit. Gene's sustained damage to the front of his Toledo Cupra, including his front suspension, splitter. He also sustained a puncture.
James Thompson brought out the second red flag after he brushed the wall by the outside of the circuit's oval corner. Remnants of his brake discs were picked up by marshals, suggesting brake failure was the cause of his accident.
The third red flag was brought out for Nicola Larini after he spun his Chevrelot backwards into a wall on the inside of the circuit.
BMW's Jorg Muller did not manage to get out in the session after sustaining damage to his car in practice. The German, sixth in the Championship, went off in avoidance and hit the inside wall when Giuseppe Ciro spun infront of him.
Colciago's teammate Adriano De Micheli similarly did make the session after sustaining too much damage to his Honda Accord in a separate practice accident.
