The grinding of the concrete Sambodromo frontstretch section of the 2.6-mile São Paulo street course not only solved the adhesion issues IZOD IndyCar Series drivers experienced on 13 March, but also improved lap times by about four seconds in the rescheduled qualifying session.
"The response by all parties to the concrete issue symbolised the can-do approach all of our Brazilian hosts have exhibited throughout this process," said Terry Angstadt, president of the commercial division of the Indy Racing League.
"We couldn't be more pleased with all aspects of our first race here, despite the tight timeline. At each and every stage, when a problem arose, the Brazilian team found a solution."
Construction of the circuit didn't begin in earnest until 15 January, under the director of Tony Cotman. With packed grandstand and suites, the event was hailed as a huge success, with IRL competition and racing operations president Brian Barnhart praising mayor Gilberto Kassab, race promoter Bandeirantes and Cotman.
"Every track we have been to since 1996 has had a challenge at one time or another, but I can't remember a better and quicker response than we have had here in São Paulo," Barnhart said, "I especially want to comment the city workers who worked through the night grinding and cleaning the track giving us a fast surface for qualifying and the race.
"We race on temporary street tracks in Long Beach, St Petersburg, Toronto and Edmonton - all excellent tracks, all with a history of competition - but, despite the limited time to design and execute this track, it ranks with the best quality and the best racing environment of any of those. The people of São Paulo should be very proud of what they have accomplished."
