This year's 96th running of the Indianapolis 500 next Monday morning (NZ time) will be the most wide open in decades.
Not only do all the teams have a new car and new engines to deal with, but there have been many off-track dramas to deal with as well.
Chief among them is a stoush between Dragon Racing and their former engine suppler, Lotus, that was resolved only just in time for Sebastian Bourdais and Katherine Legge to put a Chevrolet under the hood. It was similar for other Lotus-powered teams, including Bryan Herta Racing and Dreyer and Reinbold who have both walked away from Lotus.
On top of this, Chevrolet and Honda are at full capacity when it comes to supplying the new turbo-charged engines. Hang on though, it gets worse. Honda recently got permission to tweak its single turbo to stay in touch with the Chevy power plants.
Honda believes the new compressor cover on its turbo-charger will reduce the power disadvantage it has compared with the twin turbo-chargers from Lotus and Chevy. After four wins and four poles in four races for Chevrolet some would think the Japanese manufacturer might have a point.
