Kiwi driver Shane van Gisbergen has responded to teammate Maro Engel's comments after a disastrous Bathurst 12 hour race.

Engel hit out at van Gisbergen after the reigning Supercar champion crashed their team car into a wall with only 20 minutes of the race remaining.

Engel claimed van Gisbergen made a lot of mistakes and was too aggressive.

Van Gisbergen says Engel's comments came as a surprise to him and he apologised to him.
