INDIANAPOLIS – IndyCar officials are requiring engine manufacturers Honda and Chevrolet to make structural upgrades before this weekend's Indy Grand Prix of Louisiana.
The announcement, made Thursday, is intended to minimize the amount of damage involved in car-to-car contact. In the season opening race at St. Petersburg, some of the caution periods took longer than expected to clean up because of debris on the track.
IndyCar is using new aerodynamic kits this season.
Derrick Walker, the series' president of competition, says the upgrades include adding components that will improve the overall strength of the body work. The two engine manufacturers, Walker says, have already redesigned the components and the modifications have been approved by series officials.
