WORLD TIME ATTACK SYDNEY MOTORSPORT PARK
In 2025, we took to the world stage for the first time, participating in the WTAC held in Sydney, Australia.
Competing against the world's most advanced time attack machines elevated the team and the 4-rotor RX-7 to a new level. Having gained invaluable experience, we returned to Japan, and will take on our next challenge with a more refined setup than ever before.
Furthermore, thanks to the support of the WTAC team, we were able to secure our first major sponsorship with HARDTUNED at this tournament. I am truly grateful for the trust placed in my work and the opportunities it has given me.
My goal remains unchanged.
We will continue our challenge, aiming to create the fastest naturally aspirated machine in Japan.
TSUKUBA CIRCUIT
FASTEST NA MACHINE
In January 2026, we finally achieved our goal:
setting the fastest lap time ever recorded by a naturally aspirated (NA) machine at Tsukuba Circuit.
This result is the culmination of many years of development, challenges, and uncompromising pursuit. I would like to express my sincere gratitude to the team, supporters, and sponsors who have supported us this far.
We are aware that this record will be challenged as the level of competition within the country increases year by year.
Nevertheless, we will not stop.
With your support, we will continue to strive for even greater heights.
