HI
Decided To Make This Site Due To Ma Love For The Ford Escort Cosworth They
Are Fucking Beauty Cars and Should Have More Websites Like This
Dedicated To Them .
| The history
of the Escort RS Cosworth started many years before the first car
of that specification was produced. The history of the Escort
Cosworth started at the same moment Ford decided to put a turbo
onto the old trusty Pinto block and install it in the Sierra RS
Cosworth. That was back in 1984 and the engine produced 204 hp.
The Sierra RS Cosworth was first produced in 1986 as an
homologation special for rally. 5000 examples was required to get
a car homologated for group A. It was not particularly successful,
mostly due to the lack of four wheel drive; no wins in group A
rally. But it did have a certain amount of success in touring car
championships. |
Then there
was the Sierra RS500.
Based on 500 examples of the Sierra RS Cosworth the RS 500 had
more spoilers and 224hp. The extra airintake above the numberplate
and the extra tip on the rear spoiler are the easiest way of
distinguishing it from a standard Sierra Cosworth. Only twenty
more hp was produced from the following additions: Garrett T4
turbocharger, much larger intercooler, 8 injectors (only 4 were
used on the standard car), 9mm bigger intake manifold and thicker
engine block walls. Probably Ford's most successful car to date it
did win the only World touring car championship that was ever
held, and had 40 victories in row in the BTCC. |
| When the
required 5000 examples of the three door Sierra RS Cosworth was
produced Ford felt that they needed a camount of
power but with more comfort and ability to carry the family too.
The answer to these requirements was the rear-wheel-drive Ford
Sierra Saphire Cosworth. It used a standard 4 door sierra body
with the the same engine, suspension and drivetrain as the 3-door
Sierra RS Cosworth. the body was modified slightly from the
standard Sierra with different airintakes, fog lights, and a new
lowr with the same aer lip on the front bumper. A small rear boot spoiler was also
added to counter aerodynamic lift at high speeds. |
| After the RS500
there was an empty slot in the Ford motorsport department. They
needed a new car to keep up with the Lancia Delta HF Integrale and
the Audi Quattro. This lead to the development of the 4-door
Sierra RS Cosworth 4wd. It looked very similar to the Saphire 2wd,
but underneath the body the changes very many. It had Ferguson 4
wheel drive system with two viscous couplers; one on the center
diff, the other on the rear diff. Torque split was 34% to the
front and 66% to the rear wheels. The engine was improved, having
changed 80% of the parts compared to the Saphire Cosworth. The
changes included new modified RS500 block, stronger head and
stronger pistons with new gudgeon pin placement to decrease piston
slap. A new Garrett T03 turbo, new intake manifold and bigger
intercooler was also installed. This lead to a powerincrease of
only 224hp, but much more was available when tuning the engine.
But none the less; it still did not fulfill Ford's expectations.
It did not score a single group A win in it's two years of
rallying. The reason the Sierra Saphire didn't produce any decent
results was probably due to it's weight and size. Ford simply
needed a smaller car. The suitable model for the time was the
Escort. |
But there was
no Escort that could be homologated as a rallycar as it had to
have turbo and four wheel drive. So a new variation of the Escort
model had to be produced. Ford knew they had a great engine in the
YBG that sat in the the Sierra Saphire, so Ford's master plan was
to simply put the engine, drivetrain and suspension of the Sierra
Saphire 4wd into a modified and strengthened Escort shell. But, to
Ford's dismay I suppose, it was simply not possible so a new
chassis and body had to be built specifically for the Escort RS
Cosworth. After 400 new parts a new car was born: more than twice
as stiff and strong a standard Escort Chassis. The Escort Cosworth
shares only 50% of it's body panels with the standard Escort. The
most prominent features of the new body is: New hood with two
vents helping in the removal of hot air from the engine
compartment. New wider front arches with air exits from the engine
in front of the doors. New wider rear wheelarches. New Front
bumper with huge airintakes and low front spoiler with adjustable
splitter. New low rear bumper. All this creates a car that not
only counters the aerodynamic lift at high speeds but creates
downforce too. At 180km/h the downforce is 45N at the front, with
the splitter at it's middle position, and 190N at the rear.
Ford did not have the space to build the Escort Cosworth, so the
car was put together by Karmann in Germany. The production of the
Escort Cosworth started on the 19th of February 1992.
The Escort RS Cosworth was Ford's new rallycar and was much more
successful at it than it's earlier brothers; the Sierra Cosworth
in two and four wheel drive versions. The total count of victories
came to 8 in group A, and after the modifications that were made
to the car to make it a WRC car, it scored two more victories.
In 1994, after the 2500 cars required for homologation were
produced Ford put a "new", more civilized engine into
the Escort Cosworth. The new engine is basically the same old
engine in a new package. It has smaller turbo (Garrett T25) and
another engine management system. This lead to more low-rew punch,
but less boost available above 5500rpm. The new Escort RS Cosworth
was produced until early in 1996 when EU put a new set of noise
regulations for cars to work, and the Escort Cosworth couldn't
pass those without modifications. For some reason Ford then
decided to stop the production instead of changing the car so it
would be within the new noise regulations. And that was the end to
the Escort RS Cosworth. The last car rolled out of the factory on
the 12th of January 1996. Then 7.145 Escort Cosworths had been
produced. |
