France's Franck Montagny will drive for the Super Aguri team in the next three Grands Prix at least.
Montagny will also compete in the Le Mans 24-hour race in June
Montagny replaced struggling Japanese rookie Yuji Ide at the Nurburgring two races ago and makes his first start in Sunday's Monaco Grand Prix.
And he has now been confirmed for the British, Canadian and US Grands Prix.
"I am thrilled to have the team's confidence and to be able to do these extra races or them," Montagny told his official website.
