Alexander Rossi has secured a seat for the 2016 Indycar season with Andretti Autosport after failing to secure a spot on the F1 grid.
Rossi was in the frame for the final seat at Manor alongside Pascal Wehrlein but was overlooked in favour of Indonesian driver Rio Haryanto. The American driver drove for Manor in five races last season and performed well against team-mate Will Stevens on those occasions but eventually lost out to the superior finances of Haryanto.
Rossi has been given the No.98 Honda-powered car and will take part in the series' rookie test starting next Tuesday at Sebring.
"I'm very much looking forward to making my Indycar Series debut this season and am proud to be racing with a team of such high calibre and pedigree as that of Andretti Autosport," Rossi said. "As a racer through and through, I cannot wait to get started; our goal is to be competitive immediately at the first race in St. Petersburg."
Rossi will partner Marco Andretti, Ryan Hunter-Reay and Carlos Munoz. The team has recently merged with Bryan Herta Autosport.
