Ford gun Scott McLaughlin has returned fire at Dave Reynolds and labelled his Holden rival immature as the Supercars stars continue their public slanging match.
Reynolds called McLaughlin "boring", "precious" and "corporatised" this week following the New Zealander's rise to the top of the sport and utter domination this season.
The simmering feud first erupted when their cars collided at the Townsville 400 last month and McLaughlin accused Reynolds of a "desperado" move.
McLaughlin has won 14 of 20 races for DJR Team Penske this season and leads the drivers' standing by 433 points ahead of teammate Fabian Coulthard.
