Wheldon remained with CGR for the 2007 season. He began the season with a pole position at the season-opening XM Satellite Radio Indy 300 at Homestead–Miami Speedway. He led for 177 of 200 laps to win his third successive event at the track, a new series record. Wheldon then led for a race-high 177 laps to claim the victory in 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 Andrettit, 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.
