The following year, Nadeau moved to M.P.H. Racing and planned to run ten races in the Busch Series in 1996, in combination with a full season in the Formula Opel European Union Series Championship. He ran only two races in the Busch Series, finishing thirty-ninth in both races and did not qualify at Darlington. In Formula Opel, he drove a partial season, running in thirteen out of seventeen races for six teams and finished sixth overall, the highest for an American driver. He later declined a move into the Formula 3000 series, opting for a return to NASCAR. In November 1996, Nadeau and Barber Dodge Pro Series driver Tony Renna represented the United States in the EDFA Nations Cup held at Donington Park and won the silver medal, finishing behind Germany.
