Lowndes says he is looking for opportunities to compete in more endurance races, and will be pushing for a drive in the French classic as early as next season.
“When the opportunity came up to race with the Joest guys (at Bathurst), it was definitely pretty hard to refuse,” Lowndes told Speedcafe.com.au.
“This is hopefully a stepping-stone to the Le Mans 24 Hours, which is really the ultimate race I'd love to do one day.
“Hopefully we're on the podium somewhere (this weekend).
“That'd be a great result for me, and then the bigger picture would be trying to secure, or at least build a relationship with them (Joest) to try and do the Le Mans 24 Hours, probably more likely next year or beyond.”
