Ku dhammaystiro weedhan soo socota: Bonnier wuxuu ku soo laabtay inuu ku biiro kooxdiisa 1966kii, isagoo ku hoos jiray magaca Anglo-Suisse Racing si uu u muujiyo deganaanshihiisa Switzerland waqtigaas. Gaadhigiisa ugu muhiimsan sanadkaas wuxuu ahaa Cooper-Maserati T81, oo lagu rinjiyeeyay Swiss tartanka casaanka iyo caddaanka. Sanadka wuxuu bilaabmay si rajo leh xilli ciyaareedkii furitaanka ee aan aheyn Horyaalka 1966 BRDC International Trophy oo ka dhacay Silverstone Circuit, iyadoo Bonnier uu u qalmay Cooper kaalinta lixaad oo uu dhammeeyay kaalinta saddexaad, laakiin inta ka hartay xilli ciyaareedkii farxad yar bay keentay. Shil baabuur oo ka dhacay wareegii koowaad ee
Belgian Grand Prix wuxuu burburiyay Cooper T81-kiisa. Intii baabuurka la dayactiray Bonnier wuxuu galay Alf Francis oo dhisay Cooper-ATS ee Grand Prix-ka Faransiiska. Kadib markii Cooper-ATS aysan cadeyn inay tartan ku tahay tababarka Bonnier waxay heshiis la gashay kooxda Brabham waxayna wadeen baabuurkooda dayactirka inta ka hartay usbuuca dhammaadka. Bonnier's Cooper T81 waxaa lagu dayactiray waqtigii loogu talagalay Dutch Grand Prix ka dib markii uu ku kaxeeyay Brabham BT7 ee British Grand Prix. Dhibcaha ugu horreeya ee horyaalka ee Anglo-Suisse Racing waxay ka imaan doonaan xilli ciyaareedka xidhitaanka 1966 Mexico Grand Prix, laga bilaabo kaalinta lixaad.
