Hart ran for 187 yards on 35 carries and scored two touchdowns, and Ryan Mallett threw for three scores, leading the Wolverines to a 38-0 win over Notre Dame on Saturday.
Michigan handed the Fighting Irish their worst loss since beating them by the same score in 2003. The Wolverines (1-2) avoided their first 0-3 start in seven decades.
Notre Dame (0-3) is winless after three games for just the second time in school history, putting coach Charlie Weis in unwanted company with Bob Davie.
The Fighting Irish have lost five in a row for the first time since the 1985-86 seasons, Gerry Faust's last year and Lou Holtz's first.
In an unprecedented matchup of the storied programs, Michigan looked like it might not be that bad while the Fighting Irish appeared to be even worse than expected after losing to Penn State and Georgia Tech by a combined 51 points.
Hart backed up his prediction of a win with a sensational performance, even against a defense stacked to stop him.
Notre Dame freshman Jimmy Clausen was 11 of 17 for just 74 yards and an interception. He was sacked seven times, leading to the Irish's rushing total of minus-6.
