Today is the big day: the main event at the World Time Attack Challenge in Sydney, Australia. And things have suddenly become very serious. With cooler temperatures today, the laptimes have come down. In the latest Pro class session, two cars have comprehensively smashed the 1:30 barrier. 

Currently at the top of the timing screens is David Empringham, steering the SSE Evo to a staggering 1:29.024.

Tarzan Yamada is currently second with a 1:29.751. To give you an idea of how fast these two cars are, last year's winning time (Yamada driving the Cyber Evo) was 1:30.587.  

 

And literally a few minutes ago the Sierra-Sierra team blocked off their pits from all photography and prying eyes, with the car hidden behind enormous Hankook banners. Before the banners went up, Andrew Foy from Downshift caught a glimpse of the Evo which had its manifold off.

Many of the Pro class cars have only been doing installation laps, so it's going to be a very interesting day as it's now time for everyone to reveal their cards.
