More than 100 entries have been confirmed for one of the biggest events on the Australian motorsport calendar, the Yokohama World Time Attack Challenge (WTAC), which takes place at Sydney Motorsport Park over two days of jam-packed action. 

As usual the mammoth entry list will be split into respective classes including Emtron Pro, Plazmaman Pro-Am, GCG Open as well as the 2023 Haltech Clubsprint, with each class to tackle multiple 15-minute sessions across the weekend and attempt to post the fastest possible lap time before Sunday afternoon – where the top five fastest drivers from each class will then compete in a bonus Shootout session to determine the winner.

Headlining the popular event will be three-time winner Barton Mawer, and two-time winner Tim Slade, as well as Japan’s Yuusaku Shibata – all of whom are in the Pro Class, with Mawer and Slade looking to add another milestone to their already impressive WTAC resumes.  

Mawer will be looking to make it four outright wins in a row in his ever-successful Porsche 968, while Slade will aim to spoil the party and take his third victory in the Nissan Silvia S13.  

Former Pro-Am class winner, Robert Nguyen will also feature as part of the Pro class this weekend in his Nismo Super GT 350z, while a new Pro-Am class winner is guaranteed with no former victors to take part.  

Motorsport, racing and car enthusiasts are encouraged to make their way to Eastern Creek to witness what is known as one of the most thrilling motorsport events of the year, with plenty of on and off-track entertainment throughout.

New for 2023, the Turbosmart Flying 500 head-to-head will see two competitors’ line up alongside each other and race their rivals to the finish line, repeating until an eventual champion is crowned.

The exciting new format will take place late in the afternoon on both Friday and Saturday, alongside the International Drifting Cup, presented by Garrett Advancing Motion.  

The latter will see competitors randomly drawn into pools, where they will perform side-by-side and judged on their drifting abilities and performances.  

Other on-track entertainment includes the V10 Battle, Exedy Hot Rod Drift Show, the Spoon Civic Demonstration and more.  

Off the track, fans will be able to check out the huge trader area available on site, while also treated to a Lamborghini display and the Matt Hall Stunt Plane activation. There will also be opportunities to see the action up close with a pit lane walk on Sunday afternoon.  

The 2023 Yokohama World Time Attack Challenge will take place at Sydney Motorsport Park on 1-2 September.
