In 2006, Kelly won the Australian V8 Supercar Championship Series after being one of the most consistent performers throughout the season. The victory, however, was not without its share of controversy. Despite not winning a single round overall (though he did win an individual race), or scoring a pole position in any individual race, Kelly entered the final round of the series at Phillip Island seven points ahead of his nearest competitor, Craig Lowndes, (who had won four rounds) due to consistent high points finishes in all twelve of the previous 2006 rounds.
