Organisers hope for smooth event

The first three rounds of this year have all taken place at venues that are new to the series, and every event last year was a first visit for A1GP.

The last round at Beijing was heavily disrupted by circuit problems, which caused the majority of practice and qualifying to be cancelled.

But A1GP chief operating executive David Clare believes that things will be a lot easier as the series has its first experience of returning to a track it has previously raced on.

"So far, as a series, we've had to learn as we've been going along visiting new circuits, but at Sepang we can consolidate our experience," he said.

"This is the second time we have been to this circuit so we will be up to speed right away and we can show how far we have come."

The wide circuit that was built for Formula One produced great racing in A1GP last year, although the crowd was quite small for the event.

A much larger crowd is expected for this weekend's event, given the recent success of the Malaysian team, who have taken three wins since the Sepang event in 2005.
