Marco Andretti, Tomas Scheckter and Vitor Meira tested a modified aerodynamic package that Indy Racing League officials hope will allow for more passing and even better competition at the 2010 Indianapolis 500.
Officials removed the vertical wickers from the rear-wing end fences and moved the rain light toward the rear attenuator, all designed to reduce aerodynamic drag and turbulence behind the cars.
Andretti and Scheckter said they're confident the changes will be for the better, although the changes aren't very noticeable without a large pack of cars running together.
“I think the big thing is how it (the car) reacts in traffic,” Scheckter said. “With the rain light and end fences you've got a little bit bigger of a tow but you couldn't follow cars as closely in the corners, and to try and improve the racing maybe this is the way to go.”
