A name that stands for American racing royalty will join forces with A1GP for Season Four. Andretti Green Racing (AGR), the most successful team in Indy Racing League history, announced today it will run the US entry in A1GP beginning at Zandvoort this weekend.

"We are very proud to be representing the United States on the level and competitive playing field that is provided by A1GP," said team co-owner, Michael Andretti, who will be on hand at Zandvoort to announce the team's driver lineup. "Andretti Green has been fortunate to enjoy a reasonable amount of success in just six seasons of operation and we're looking forward to joining the world stage of A1GP."

Andretti Green Racing, which is owned by Andretti and partners Kim Green and Kevin Savoree, has taken three IndyCar Series championship titles (2004, 2005, 2007), two Indianapolis 500 wins (2005, 2007), one Firestone Indy Lights championship (2008), an overall American Le Mans Series (ALMS) victory at the 2008 Detroit Sports Car Challenge and an LMP2 class victory at the ALMS 12 Hours of Sebring (2007).

A1GP Chairman, Tony Teixeira, commented: "We are proud to have such a successful and well respected team involved with our series. Over the years some of the most famous names in motorsport have been associated with the A1GP, and to have one that is synonymous with racing at its highest level in the United States can only help to raise the profile of the series both there and worldwide."
