Karl Wittmer is a Silver-graded professional endurance racing driver competing in IMSA Pilot Challenge since 2021. His rating of 4,302 places him in the professional band, the level of a national championship front-runner who beats semi-professionals comfortably. Across six seasons with MMG, he has recorded 6 wins and 16 podiums from 47 starts, averaging a finishing position of P6.9. His most recent campaign in 2026 brought 1 win and 3 podiums across 6 rounds, finishing fifth in the season standings.[1]
Wittmer's record against his peer group shows a mixed head-to-head picture. He trails more often than he leads against several Silver-graded rivals of similar rating; Harry Gottsacker, a one-time champion also graded Silver, finished ahead of him 31 times to Wittmer's 16 in 47 shared races, and Mason Filippi, another Silver-graded driver, leads 29 to 17 across 46 starts together. Against some rivals he has the edge. Tim Lewis, graded Bronze, finished behind Wittmer 26 times to 21 ahead, and Denis Dupont, a Silver-graded one-time champion, shows a near-even record of 24 to 21 in Dupont's favour across 45 races. Wittmer has occasionally beaten much stronger drivers; he finished ahead of Robert Wickens, a two-time Silver-graded champion, 8 times across their shared races.
The body of Wittmer's work lies in the Pilot Challenge one-make and pro-am field, where he has established himself as a consistent podium threat for the MMG stable. Recent form includes a four-hour victory at Mid-Ohio in 2026 and pole position at the same venue the previous year.
