Triple challenge for Tassie.

V8 Supercar Champion Marcos Ambrose wants to celebrate the return of Australia's premier motor sport event to his home state by sealing a second successive championship at the Tasmanian Triple Challenge at Symmons Plains in Tasmania.

It has been announced that if Ambrose is to win the Tasmanian Triple Challenge it will be achieved across three 100km races - one on Saturday November 13 and two on Sunday November 14 - in front of specially installed grand stand seating that will be in place at Symmons Plains for the first time.

"All things going well in the next three critical rounds I'd love nothing more than to secure my second championship title in front of a record crowd of Tasmanian supporters," Ambrose said of what will be the second last event on the 2004 V8 Supercar Championship Series calendar.

"It's also great to know that the Tasmanian fans will be looked after with the initiatives of grandstand seats and plenty of race action on offer over the two days.

"I'm an extremely proud Tasmanian and it really means a hell of a lot to me to get the chance to race at home. Incredibly, I've never raced in a V8 Supercar at Symmons Plains which is exciting and a great challenge."

To further enhance the experience a number of giant screens will be strategically placed around the venue to ensure fans don't miss a minute of the action no matter where they are watching from.

Symmons Plains will also be undergoing significant upgrades in the next two months including the completion of full pit lane facilities for all teams with a scheduled completion date a year ahead of schedule.

Tasmanian Minister for Tourism, Parks and Heritage Mr Ken Bacon announced the three-race format, grandstand seating and the availability of park and ride facilities for event patrons at today's launch.

Bacon was joined by Ambrose, fellow Tasmanian driver John Bowe, series leader Jason Bright, third placed Steven Richards and AVESCO CEO Wayne Cattach.

"We are so proud to have the V8 Supercar Championship Series back in Tasmania that we will do everything in our power to ensure it remains as one of the feature events on the series calendar," Bacon said.

"This also applies to those who attend the event. We have added grandstands, big screens and will provide a park and ride shuttle service to make their experience even better.

"The park and ride system will make people's travel to and from the race much smoother."

Mr Cattach said the Tasmanian Triple Challenge was shaping up to be one of the best events on the V8 Supercar Championship Series calendar.

"We are absolutely delighted with the way this event is coming together," he said.

"The hard work done by Premier Paul Lennon and his team to fast track the development of pit facilities at Symmons Plains will ensure our championship can put on the best show possible.

"With the news of the addition of pit garages we were able to develop a special race format to ensure there is great V8 Supercar racing action on both Saturday and Sunday complete with pit stops.

"This event is really gaining momentum and with the interest from both local and interstate fans growing rapidly we have made available a limited number of reserved grand stand seating."

The improvements will be followed in the second year by permanent corporate, media and administration facilities as well as more improved spectator facilities.
