"My whole focus is on this year's V8 Supercar championship, however I look forward to working with the crew and being a part of the development process of Car of the Future.''
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.
Team Vodafone boss Roland Dane expressed delight with Whincup's re-signing just a fortnight after Lowndes re-committed.
Dane is now convinced his team can continue their dominance of the series with the two men he considers the sport's best drivers.
"With both Jamie and Craig on board I know that we have the strongest driver line-up in the V8 Supercar championship series,'' Dane said.
"Jamie has time and time again proven to be not only the ultimate winner but also the ultimate fighter.''
Whincup currently sits second in the championship after the opening races of the series in Adelaide earlier this month.
He will compete in the V8 Supercar non-championship round as part of the Australian Formula One Grand Prix.
Qualifying will be held on Thursday ahead of two races on Friday, one on Saturday and one on Sunday.
The next round for championship points is scheduled for Launceston from March 30 to April 1.
