There are few motorsports venues more iconic than the Indianapolis Motor Speedway. Of the places I've visited, only Monza comes close: you can feel the ghosts of all the men and women who have raced there. With its massive grandstands and historic racing museum, the vast facility is breathtaking. It is a magic place.
Sadly, the magic is all around the 4 kilometer rectangular oval on which the Indy 500 is held, and not so much around the road course used by MotoGP. The rather tight, artificial infield road circuit feels very much like an afterthought, something retrofitted to allow a greater range of activities at the facility. If the oval layout is spectacular, the road course is positively pedestrian.
To the credit of the Speedway, they have done an awful lot to try to improve the track. Last year, there were at least four different types of asphalt around the circuit, and the infield section was considered too tight for overtaking maneuvers. In an effort to solve both those problems at a stroke, turns 3 and 4, turn 7 and turns 15 and 16 have all been modified. The changes are aimed at opening the corners up a little, making them a little faster and more flowing. The change at turns 3 and 4 should make for more natural corners, and a better transition back onto the outside oval. Turn 7 has been altered to open it up, making a more natural chicane rather than the right-angle corner it was before. Turns 15 and 16 are now a little more flowing, and again have been modified to provide a more natural transition onto the oval. At the same time, the infield has been completely resurfaced, so that it now has just one type of asphalt.
