Subaru Impreza
The Subaru Impreza WRX
STI (often referred by auto-enthusiasts as
simply STi or also colloquially pronounced
as the "Impreza Rex Ess-Tee-Eye";
in 2006, the acronym had the 'I' capitalized;
hence it is currently STI) is the highest
trim in the Subaru Impreza line (excluding
the limited edition special cars). Subaru
uses the WRX as the basis for it World Rally
car in the FIA World Rally Championship. Subaru
created Subaru Tecnica International to handle
its motorsports activities. After the company
had grown, it was used to make highly-tuned
high-performance versions of the Subaru Impreza
WRX, a 4WD sportscar with a turbocharged flat-4
engine.
There were 6 noted versions
of the STi. The different versions were marketed
with consecutive numbers. Another way to tell
the verison of a WRX STi was to look at the
chassis code. All WRX STis have the beginning
chassis code of GC8 then followed by a letter
from A to G. Version
I (1994) - GC8A/B: The first STi had 250 PS
(184 kW) @6500 rpm and 31.5 kgf·m (309
N·m) @3500 rpm and weighed 1230 kg
(2,710 lb). This version was the only version
where the standard cars were taken at the
end of the assembly line and replaced by STi
parts. After this version, the standard STi
was built alongside the WRX on the production
lines.
