Team USA will give JR Hildebrand his A1GP race debut at Brands Hatch next weekend, in place of Marco Andretti.

Andretti has raced for the team since the second round of the year, alongside his IndyCar campaign in America, but will sit out the British event which takes place just three days before the first practice session for the Indianapolis 500.

Hildebrand is also racing in Indy Lights and won at Long Beach last weekend. He has also taken part in the A1GP rookie sessions in Malaysia, New Zealand and South Africa this year.
