DEAR RADICAL FAMILY

It is a true privilege to be writing to you

all in our 26th year in business, and in the
very first edition of Radical magazine. A decade
ago, our focus was on survival rather than
creating new opportunities and celebrating
success. Now we have established our position
as the world’s largest purpose-designed race
car manufacturer, with representation in
more than 20 countries.
As the world is moved on to a diet of
electric powertrains, I am delighted that we
continue to offer what is arguably the most
visceral experience per dollar available on
four wheels. In conjunction with the brand’s
global dealer network, we also offer the very
best international bucket-list track experiences,
with 12 national race series across the globe. It is great to see the camaraderie in the

We capped off 2022 with a landmark World
Finals event at the spectacular Spring Mountain
Motor Resort. This year, we look forward to an
equally exciting end to the season with the
2023 World Finals taking place in Portimão,
supporting the European Le Mans Series. Our
vision is to hold a World Finals event in
the final quarter of every year, bringing
