Tuhia he haere tonu mō tēnei wāhanga - Mō te tau 1968, i hiahia a Cooper ki te whakauru atu ki te rārangi mō te Cosworth-Ford DFV, engari i whakaaro ia e kore e tika te hono atu ki a British Leyland me ngā Mini-Coopers. Engari, i whakaritea he kirimana ki a BRM mo te whakamahinga o tana 3-ra V-12, i whakaarohia i te timatanga hei waahanga motuka hākinakina, engari ko te BRM ano ka whakamahia i te 1968. He putanga whakarerekētia iti o te T86 i hangaia mo te miihini hou, i tapaina ko te T86B me te kaihauturu o mua o Ferrari o Itari a Ludovico Scarfiotti me te taiohi Ingarihi a Brian Redman i whakamahia ki te taraiwa. I taea e ngā motokā te whakaoti i te toru-wha i te reo Paniora
me te Monaco Grand Prix, i te nuinga o te whakawhetai ki te kore pono o te whakataetae, engari i mate a Scarfiotti i te taraiwa o te Porsche i te piki o Rossfeld me Redman he aitua nui i te Belgian Grand Prix i waiho ai ia i te mahi mo etahi marama. I haere tonu a Cooper i te wa me te kohinga o nga taraiwa, kaore tetahi i taea te mahi i tetahi mea o te T86B. I te wa o te wa, i hangaia e Cooper he taraiwa whakarereke, te T86C, i hangaia hei tango i te Alfa Romeo 3-ra V-8 engari i mate te kaupapa.
