Hildebrand to replace Andretti
Regular driver Marco Andretti is unavailable for selection due to his IRL IndyCar commitments, and so the team will allow Hildebrand the chance to make his debut on the notoriously tough British circuit.
Hildebrand is in strong form, having just come off victory at last weekend’s Indy Lights race in Long Beach, California. He has competed in three rookies sessions for the squad this season, making the top ten running in each session.
"I'm really looking forward to the opportunity to drive for A1 Team USA and Andretti Green next weekend at Brands Hatch," said Hildebrand.
"Marco and the guys have done a good job learning more and more about what we need and I hope to make the most of all their hard work. I've really enjoyed driving in the rookie sessions at the other A1GP rounds I've attended and am excited to be able to take the car all the way through the weekend."
