Bobby Rahal oo ku guuleystay Indy 500 iyo kooxdiisa Truesports ayaa sameeyay isbedel aad loo xayaysiiyay oo ka yimid shaashadda Maarso ilaa shaashadda Lola ee soo socota. Truesports, si kastaba ha noqotee, waxay la joogtay mashiinka Cosworth ee la xaqiijiyay. Sannadkii 1987, Ilmor Chevrolet Indy V-8 wuxuu ballaariyay kaqeybgalkiisa, isaga oo soo saaray gawaarida Penske Racing, &lt;a href="Newman/Haas%20Racing"&gt; Newman/Haas&lt;/a&gt; iyo Patrick. Mario Andretti wuxuu dhaliyay guushii ugu horeysay ee Indy ee baabuurta ee xilli-ciyaareedkii furitaanka ee Long Beach. Sidoo kale ku biirista taxanaha waqtiga buuxa wuxuu ahaa Judd AV V-8 (oo markii hore loo yaqaanay Brabham-Honda), ka dibna xilli ciyaareedkii Porsche wuxuu sameeyay baabuurkiisii ugu horreeyay ee Indy. Penske waxay dib u bilaabeen barnaamijkooda shaashadda gudaha, laakiin ka dib natiijooyin xun oo ay la yimaadeen PC-16, gawaarida ayaa la dhigay inta lagu guda jiro tababarka Indy iyagoo doorbidaya March 86C.
