STI - rallying success
at all levels
Subaru and its motorsport division STI have a rich
and successful heritage in international rallying,
particularly in the production category.
Subaru Impreza rally cars have won six FIA
Production Car World Rally Championship titles
in the last decade alone and the Japanese
manufacturer has won 47 world rallies outright, as
well as three world drivers’ titles and three world
manufacturers’ crowns since 1995.
Rallying has been at the heart of the STI brand for
close to 25 years and joining forces with JRM has
allowed Subaru’s performance division to record
even more success in various territories, particularly
Europe.
It’s worth noting that JRM’s 2014 Subaru WRX
STI production rally car led every round of the FIA
European Rally Championship that it entered and
set a number of fastest stage times along the way.
