Richard Petty Motorsports has re-signed Sprint Cup Series drivers Marcos Ambrose and Aric Almirola for the 2013 season.
It will be Ambrose's third season at RPM. He will again be behind the wheel of the No. 9 Ford. It will be Almirola's second season in the No. 43 Ford.
Director of Competition Sammy Johns believes ''the chemistry that we are developing now with both teams is very strong.''
Both drivers changed crew chiefs twice this season while searching for the right combination.
Ambrose, who won at Watkins Glen earlier this season, will be teamed with crew chief Drew Blickensderfer in 2013. Blickensderfer joined the team earlier this season.
Almirola, who has three top-10 finishes this season, will be paired with veteran crew chief Todd Parrott next season.
