Two-time MotoGP champion Casey Stoner will put an end to his V8 Supercars career after just one year in the series.
The Australian, who quit MotoGP at the end of the 2012 season, switched to four wheels this year, joining the V8 Supercars' second-tier Development Series. Stoner has struggled to be competitive in the series, and is currently in 18th position in the standings with two races remaining.
The 27-year-old said he will be taking a break from any form of competition after the season ends.
"To be honest, after this year, I realized I want to get away from competition for a little while," Stoner told Reuters. "I will probably do some car racing here and there in different times.
Stoner fueled speculation about a possible return to MotoGP earlier this year when he completed a two-day test with the Honda MotoGP squad. He has insisted he has no intention of going back to racing, however.
