Waxad ku qortaa sii socodka faqradan - qeexitaannada farsamada ee Indianapolis 500 waxaa hada qoraya IndyCar. Guud ahaan xeerarku waa isku mid sida tartamada kale ee IndyCar. Waagii hore, gaar ahaan xilligii USAC ay caddeysay Indy 500 (laakiin CART waxay caddeysay tartamada kale ee Indy), xeerarka Indy ayaa xoogaa ka duwanaa mararka qaarkood. Natiijada, tusaale ahaan, waxay noqon kartaa shaashad gaar ah ama qaabeynta mashiinka oo sharci ah Indy, laakiin maahan sidaas dhacdooyinka CART-lagu oggolaaday. Tani waxay ahayd mid caadi ah 1980-meeyadii iyo horraantii 1990-meeyadii, markii matoorrada "stock-block" (sida V-6 Buick) loo qoondeeyay heer sare oo ah kor u qaadista turbocharger ee USAC ee Indy, marka la barbar dhigo matoorrada V-8 ee loo dhisay ujeedada. In kasta oo matoorrada "block block" ay si farsamo ahaan sharci u ahaayeen tartanka CART, haddana lama siinin faa'iidada kor u kaca, taas oo si wax ku ool ah uga dhigtay mid aan tartan ahayn, oo ka horjoogsatay isticmaalkooda kooxaha. Muuqaalka ugu caansan ee kala duwanaanshaha xeerarka USAC wuxuu ahaa Ilmor-dhisay Mercedes-Benz 500I engine oo uu soo saaray Roger Penske 1994
