Tuhia he tomokanga mō tēnei wāhanga - Mō te tau 1994 i kite ia i te whakataetae mai i a Michele Alboreto rāua ko Luca Badoer kia eke ki te noho tuarua ki Benetton i te taha o Michael Schumacher. Heoi, i whara ia i tona kaki e whakamatautau ana i te B194 hou i te wa o mua me te kaihauturu whakamatautau a Jos Verstappen e whai waahi ana mo nga rauna tuatahi e rua o te whakataetae. I hoki mai a Lehto ki te kokonga mo te San Marino Grand Prix kino ahakoa etahi tohu patai mo tona kaha. I eke ia ki te tuarima engari i mau ia i te tīmatanga, i patua tana motuka mai i muri e Pedro Lamy's Lotus. Ahakoa te rere tuatoru i Spain i mua i te ngoikoretanga o te miihini me te whiwhinga i tetahi tohu i Kanata (i muri i te whakakore a Christian Fittipaldi) i maarama kaore i tino ora ona whara ka whakakapihia ano e Verstappen mo te French Grand Prix. Hoki ia ki te kokopi mo te Italian
I whakawhiwhia ia ki ngā rauna Portuguese hei whakakapi i a Schumacher i whakamutua, engari kāore i whakamīharo, ā, i tukuna katoatia i muri tata iho i te wa i hainatia e te kapa a Johnny Herbert. Na tenei i tuku ia ki te taraiwa i nga rauna e rua whakamutunga mo Sauber <unk> Ko nga wharanga a Wendlinger mai i te aitua i te whakangungu i mua o te 1994 Monaco GP kaore i ora, a kaore i taea te uru atu ki tana whakakapi o mua a Andrea de Cesaris.
