V8 Supercar champion Jamie Whincup has pledged his long-term future to Team Vodafone and Holden, agreeing to a new three-year deal.
Whincup will remain with the team he's won three championships with until the end of 2015.
His contract also locks in the key pieces of Holden's V8 Supercar campaign going into a new era next year when additional manufacturers will be allowed into the series to join Holden and Ford.
Already Holden has pledged medium-term financial support to Team Vodafone and Holden Racing Team.
Team Vodafone has signed Whincup's teammate Craig Lowndes for the next three years, while HRT has Garth Tander and James Courtney under contract.
