Ku qor sii wadida faqradan - Marka la xaqiijiyo bixinta qaybaha dayactirka bartamihii xilli ciyaareedka, B186s ayaa wax laga beddelay si loogu daro noocyo badan oo astaamo aerodynamic cusub ah (oo ay ku jiraan baalasha hore iyo gadaal iyo qaab dhismeedka dib loo eegay), xirmooyinka ganaaxyada cusub, iyo fikradaha qaabeynta dib loo eegay. Shaashadda ayaa sidoo kale la sii xoojiyay si ay ula qabsato culeyska ay keento awoodda mashiinka BMW. Xirmada horumarinta waxaa lagu dhammaystiray imaatinka naqshad cusub oo garabka dambe ah oo loogu talagalay Abaalmarinta Weyn ee Austria, halkaas oo waxqabadka la hagaajiyay ee B186 iyo wadada xawaaraha sare ee Österreichring ay ka dhigtay gaariga ugu dhakhsaha badan garoonka iyadoo Fabi (pole) iyo Berger ay qabsadeen safka hore ee shabakadda. Tartanka baabuurku wuu fiicnaaday xilli ciyaareedkii oo dhan, gaar ahaan qeybtii labaad, taas oo ka dhalatay horumarkan. Waxa kale oo ay noqotay mid la isku halleyn karo, in kasta oo dhinacan uu ahaa mid shaki ku jiro sanadka oo dhan iyadoo wadar ahaan sagaal iyo toban ka fariistay 32 bilow. Tartanka taayirada Pirelli ayaa sidoo kale soo hagaagay, iyo adkeysigooda marka la barbar dhigo Goodyears ayaa inta badan ka ciyaaray faa'iidada B186, oo lagu muujiyey Berger oo ku guuleystay 1986 Mexico Grand Prix
sababtoo ah uma baahnid inaad sameyso joogsi loogu talagalay taayirada cusub ee taayirada halka inta badan tartamayaasha ugu waaweyn (marka laga reebo Prost's McLaren oo dhammeeyay labaad) ugu yaraan laba joogsi oo loogu talagalay taayirada sababtoo ah dusha sare ee Autódromo Hermanos Rodríguez.
