2023 Competitor Information


Calling all time attack competitors, this is your chance to join us as we welcome back the world to Sydney Motorsport Park in 2023. WTAC provides a unique opportunity to test your mettle against top-tier international cars and drivers in an all-out battle with the stopwatch.

For all classes this year, the competition is hotter than ever with current top competitors already flagging their intention to return in their pursuit of their One Perfect Lap! The last time we saw international cars at WTAC was 2019, so 2023 will be an overdue reunion of local talent and some familiar names making the pilgrimage back to the biggest time attack festival in the world.

Be warned, this will be our most in-demand year EVER as the pandemic has provided a unique stop-in-time for new cars both locally and overseas to be built in the shadows and some previous competitors having time to develop and refine their machines. Don’t underestimate the little guys, we are guaranteed to see some surprising lap times from under-the-radar builds. 

Get your ducks in a row and be the first through the gates for your best chance to compete at WTAC 2023 and have a crack at stepping onto the podium on the world stage.
