Ford star Mark Winterbottom believes Holden's next generation Commodore has thrown down a gauntlet to the rest of the Supercars field.
The new model Commodore - the ZB - made its Supercars debut at the Adelaide 500 this weekend and wasted little time getting into the winner's circle following Shane Van Gisbergen's victory in Saturday's 250km season opener.
Van Gisbergen has also swept the pole positions at the Adelaide 500, proving the ZB - the first Supercar based off a hatchback road car - has one-lap speed as well as race pace.
Rivals, particularly those driving Falcons, have raised concerns about a supposed weight advantage with the new Commodore.
