Off the track, the 2001 season was an unmitigated disaster for CART, featuring two race cancellations, a disastrous European tour that coincided with the September 11 attacks, infighting amongst engine manufacturers that saw litigation and the announced future departure of Honda and Toyota, the loss of the series' television contract, the loss of longtime tracks Michigan and Nazareth, and the withdrawal of Team Penske at the conclusion of the season.
Team Penske and Team Motorola joined Chip Ganassi Racing in having concurrent IRL teams to run in the 2001 Indianapolis 500, with Penske's Castroneves winning the race. In an unusual move, CART "sanctioned" the participation of teams in the race; This was an attempt to allow Penske's primary sponsor, Marlboro, to appear on cars in the 500 as they were prohibited from being in more than one racing series by the Tobacco Master Settlement Agreement. This legal maneuver was not successful, and Penske's cars ran without advertising.

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.
