Wheldon remained with CGR for the 2007 season. He began the season with pole position at the season-opening XM Satellite Radio Indy 300 at Homestead–Miami Speedway, and led 177 of 200 laps to win his third successive event at the track, a new series record. Wheldon went on to lead a race-high 177 laps to win the Kansas Lottery Indy 300 at Kansas Speedway, his second of the season. After qualifying sixth for the Indianapolis 500, he retired from the rain-shortened race after a late-event collision with Marco Andretti, losing Wheldon the lead of the drivers' championship. His third-place finish in the ABC Supply Company A.J. Foyt 225 at Milwaukee Mile was overshadowed by a physical confrontation with Patrick following a collision on the 88th lap; the two reconciled after a private meeting with IndyCar president Brian Barnhart. The rest of Wheldon's season was modest, with four retirements and two further third-place finishes in the SunTrust Indy Challenge and the Detroit Indy Grand Prix. He came fourth in the final points standings with 466 accrued.
