Kiwi Shane van Gisbergen took advantage of a late safety car to win an enthralling race at Winton Raceway and fire a counterpunch back at championship rivals Shell V-Power Racing on Sunday.
The defending series champion's Red Bull Holden Racing Team found improved speed on Sunday after playing catch-up to their Ford rivals over the past three rounds and sets up a superb championship battle through the rest of the year.
Red Bull teammate Jamie Whincup held off a charging Fabian Coulthard over the final laps to ensure a one-two finish for the Holden outfit.
The safety car - the first since Phillip Island two rounds ago - was called when Michael Caruso was pushed off the track and into the tyres, which bunched the field up and left a 13-lap sprint to the finish.
New Zealander van Gisbergen got the better of the re-start and jumped his teammate Whincup while the latter was left to go back and forth in a terrific exchange with Coulthard.
