a straight. In 2002 the exit of the pitlane was changed to make exiting the pitlane safer for drivers. This also shortened the length of the circuit. Changes made in 2005 to the curbs on the final chicane were controversial amongst drivers in the run-up to the Grand Prix. The curbs were made higher and more difficult for the drivers to see, making it even more challenging. On June 23, 2006, the Canadian Press reported that the city of Montréal had awarded exclusive rights to stage the two allowed race weekends on the track to Normand Legault, promoter of the Formula One Canadian Grand Prix. The deal was for 2007 to 2011, with an option for 2012 to 2016. Legault decided to replace the Champ Car race with races from the Grand American Road Racing Association's Rolex Series and NASCAR's Nationwide Series, respectively – the latter series' first race north of the Canada-United States border. On August 4, 2007, Kevin Harvick made history by winning the first NASCAR Busch Series (now Xfinity Series) race at Circuit Gilles Villeneuve in what was one of the most controversial NASCAR races ever, as Robby Gordon claimed to have won the race. The NASCAR races have affected the circuit layout. An expansion of the pit lane took place, since a NASCAR pit lane must accommodate a minimum of 43 cars. The 2008 race made history as the first NASCAR race to run on rain tires. In 2017, due to the higher cornering speeds of the new Formula One cars and the new safety requirements imposed by the FIA, the circuit had additional Tecpro barriers installed, following the removal of older tire barriers by May 2017. With the 2017 technical regulations, experts predicted the F1 cars to be quicker by three to five seconds a lap in June at Montréal. 2017's F1 event also saw a change to the exit of the last chicane (the Wall of Champions) with its angle modified, because the FIA found it was dangerous. Senna 'S' turns The complex of turns one and two has become known as the Senna 'S'. From a bird's eye view turns one and two together can represent an 'S' shape. Since the pit-exit was redesigned merging into turn two, the 'S' shape is not so evident on first glance. Pont de la Concorde corner The very fast Pont de la Concorde corner (Turn 8)
