World Time Attack
Sydney 2026
Confirmed participation in WTAC for the second year in a row!!
WORLD TIME ATTACK CHALLENGE
Based in Kanagawa Prefecture, this project was created by Yuuki Kamakura over a period of more than 10 years.
The "4-Rotor FD" has proven its capabilities through countless tests at Tsukuba Circuit, the mecca of time attack racing. This car is truly the culmination of many years of collaboration with leading rotary tuners and time attack specialists in Japan.
And now, in order to share the appeal of Japanese naturally aspirated rotary engine tuning with the world, we will be taking on the WTAC (World Time Attack Challenge) held in Sydney, Australia.
