SAO PAULO (AP) - Honda will be allowed to make changes to the turbochargers on its IndyCar engines after a three-person panel denied an appeal by Chevrolet.
The panel decided at a hearing in Indianapolis on Thursday that Honda can change the compressor cover on its single turbocharger, a move that Chevrolet and its teams were against.
IndyCar last week decided to allow Honda to make the changes but Chevrolet protested. It can still appeal the panel's decision.
IndyCar has multiple engine manufacturers this season for the first time in seven years. Chevrolet has won all three poles and all three races in its return to the series, all with Team Penske.
Honda has a pair of second-place finishes. The next race is Sunday in Sao Paulo.
