Off the track, the 2001 season was an unmitigated disaster for CART under the leadership of Joseph Heitzler. It included two race cancellations; a disastrous European tour that coincided with the September 11 attacks and witnessed a severe accident to former series champion Alex Zanardi in which he lost both of his legs; infighting amongst engine manufacturers that saw litigation and the announced future departure of Honda and Toyota; the loss of the series' television contract with ABC/ESPN; the departure of longtime tracks Michigan International Speedway and Nazareth Speedway; the loss of Firestone as the series' tire supplier and its replacement by parent company Bridgestone; and the defection of Team Penske to the rival Indy Racing League (IRL) at the conclusion of the season.
The original calendar called for 22 races on five continents, by far the most ambitious calendar CART had ever attempted. With the race at Texas being canceled and the Rio 200 being dropped, the 2001 season ultimately had the same number of races as the previous year.
For the first time, CART would race in the United Kingdom and Germany and also return to Mexico for the first time in almost twenty years.
The original calendar released on August 5, 2000, had the first round of the season at Jacarepaguá in Brazil, but disagreements with the track owners several months later led to the event being dropped.
The removal of Gateway from the calendar meant that Memorial Day weekend would be empty, allowing several teams and drivers the opportunity to compete at the Indianapolis 500.
The 2001 season was the final time Michigan Speedway appeared on the calendar.
