Liz Halliday will make her American sportscar return in the Petit Le Mans endurance race at Road Atlanta after extending her partnership with Creation AIM.

Creation will contest the final two rounds of the American Le Mans Series, with Halliday competing with them again after making her debut in the LMP1 machine at the Le Mans Series event at the Nurburgring.

Striving for overall glory, or at least the honour of being the best petrol-powered LMP1 car, Halliday will team up with sportscar stalwart Stuart Hall and debutant Dean Stirling for two events, three years after she claimed an LMP2 Petit Le Mans victory for Intersport Racing.

"I'm excited to be back in the ALMS. I've been away for two years and it's going to be really cool seeing everybody again." said Liz. "It's a great championship and I love racing in the US - the fans are always fantastic and hopefully they will be happy to see me back in a car again."

"It's a great circuit but at the same time it's quite challenging and very easy to lose time. There's a lot of ups and downs and surface changes so that's something to look out for. It's also a heavy braking circuit that demands commitment. This will be the first time that I have driven this or any LMP1 car at the circuit so it will be a new experience for me!

"Creation have always done well in America and have proved that they are competitive here. I've got complete confidence in the team, especially after the race in Germany so I'm really looking forward to it!

Importantly for this race, Halliday's Creation will be specially adapted in order to run on a greener, cleaner bio-ethanol fuel. However, with a grid consisting of Audi, Peugeot, Porsche and Acura, the equestrian star is conscious of the challenges ahead.

"Obviously we want to finish as far up as we can with no incidents and do a good job for the team. Hopefully we can get a podium. It's going to be a tough challenge what with a grid full of Audis, a Peugeot, Porsches and Acuras but at the end of the day you've got to have a go. In a race like that anything can happen."
