They may technically be Holden teammates but there is clearly still no love lost between Supercars stars Jamie Whincup and Mark "Frosty" Winterbottom.
Seven-time series champion Whincup couldn't help but take a swipe at Winterbottom after being asked what it was like sharing the same data as his old sparring partner in the Holden garage after the Supercars opening round's first qualifying session in Adelaide.
Ford hero and 2015 series winner Winterbottom controversially joined the Holden fold by signing with Irwin Racing for 2019, ending a successful 13-season stint with Tickford Racing.
Irwin Racing boasts a Commodore constructed by Triple Eight Engineering, the same makers for Whincup's pace-setting Holden outfit Red Bull Racing (RBR).
