The final three contestants on Shannons Supercars Showdown will be put to the test behind the wheel of a Kelly Racing V8 Supercar at Winton Motor Raceway in this Sunday's episode at 5pm on 7mate.  Andrew Jordan, Cameron Waters and Samantha Reid will each be assessed by judges Todd and Rick Kelly as well as the team's race engineers, with one driver eliminated to leave just two drivers vying for victory in the final episode on Sunday October 2.  This Sunday's episode will also be the first time fans get to see the livery for the #77 Shannons Mars Racing Commodore that the winning contestant will race at the Supercheap Auto Bathurst 1000 alongside the show's host Grant Denyer on October 6-9.  "These final two episodes are when things get really serious," said two-time Bathurst winner Rick Kelly.  "This episode is the first time we put the contestants behind the wheel of a V8 Supercar and really get to test their ability in the car the winner will race at Bathurst.  "To test a V8 Supercar is a big buzz and a massive opportunity for any young racing driver.  "In this instance Andy, Cam and Sam are not only coming to grips with a 640-horsepower V8 Supercar, they are also testing for an opportunity to compete at Bathurst, the biggest motor race in Australia, so the pressure could not be more intense.  Kelly said that the Shannons Mars Racing livery was different to the team's existing liveries.  "This Sunday's episode is the first time that fans will get to see our Shannons Mars Racing Commodore and we're really pleased with how it looks," said Kelly.  "We have the black and white Jack Daniel's Commodores, our Stratco 'red rocket' and of course the ever-changing colours of the Pepsi Max Crew - and the Shannons Mars Commodore is completely different again."  It will be a Shannons Supercar Showdown marathon on 7mate this Sunday, with Episode 1 screening at 12:30pm followed by each episode all the way up to 5pm when the latest episode (Episode 10 - the second-last episode of the series) airs in the usual timeslot.  You can also watch previous episodes and exclusive online content at shannonssupercarshowdown.com.au/videos Shannons Supercar Showdown - Episode 10  Sunday 25 September 2011  5:00pm  7mate  *please check local guides  Shannons Supercar Showdown - Marathon  Sunday 25 September 2011  Commences 12:30pm with Episode 1 - 10 straight episodes aired  7mate  *please check local guides  For further information please contact:  Chris Jordan - BAM Media: +61 412 936 338  Communications Manager - Kelly Racing  SHANNONS SUPERCAR SHOWDOWN - KEY POINTS:  - New reality TV show 'Shannons Supercar Showdown' screens on 7mate Sundays at 5pm  - Hosted by Grant Denyer with V8 Supercar stars Todd and Rick Kelly as judges  - Show features 10 contestants, all young racing drivers from Australia and around the world, competing in a series of elimination challenges  - Winning contestant to race at the 2011 Supercheap Auto Bathurst 1000 alongside Denyer for 'Shannons-Mars Racing', prepared by Kelly Racing  - Show features never before seen access behind the scenes of the Kelly Racing V8 Supercars team both at events and at the team's workshop  - 'Shannons Supercar Showdown' is produced by Logie-awarding winning production company WTFN, creators of Bondi Vet, Coxy's Big Break and Trisha & Krishna - The Quest For Separate Lives  - 'Shannons Supercar Showdown' is a joint production between WTFN, The Media Mix and Kelly Racing, with motor enthusiast insurance company Shannons as the naming rights partner  FINAL THREE CONTESTANTS:  ANDREW JORDAN (Male - 21 years old)  All the way from Britain, Andrew Jordan adds international flavour.
