Tuhia he haere tonu mō tēnei wāhanga - I hoatu ki a Walker he nohoanga F1 wā-katoa hei whakahaere i te Lotus 72 i te tau 1972, hei kaihautū tuarua ki a Emerson Fittipaldi. Heoi, i te wa e haere ana te wa, ka nui haere te pouri o Walker me te roopu. Whai muri i te kitenga o Lotus kua whakamatauria e Walker tetahi motuka Momo Tuarua mo tetahi atu roopu, i tukuna ia mai i te roopu mo te GP Itari
me te Canadian GP, i whakakapia ai e Reine Wisell. I hoki mai a Walker mo te US GP, engari i reti.
