The
Audi
Sport
Quattro
was
a
Quattro
programme
car
developed
for
homologation
for
Group
B
rallying
in
1984,
and
sold
as a
production
car
in
limited
numbers.
It
featured
an
all
aluminium
alloy
2,133 cc
(130.2 cu in)
(2.1 L)
20v
DOHC
engine
slightly
smaller
than
that
of
the
Audi
Quattro
(in
order
to
qualify
for
the
3-litre
engine
class
after
the
scale
factor
applied
to
turbo
engines).
In
road-going
form
the
engine
was
capable
of
producing
225 kW
(306 PS/302 bhp),
with
the
competition
cars
initially
producing
around
331 kW
(450 PS/444 bhp).
The
vehicle
also
featured
a
body
shell
composed
of
carbon-kevlar
and
boasting
wider
arches,
wider
wheels
(nine
inches
as
compared
to
the
Ur-Quattro's
optional
eight
inch
(203
mm)
wide
wheel
rim),
the
steeper
windscreen
rake
of
the
Audi
80
(requested
by
the
Audi
Sport
rally
team
drivers
to
reduce
internal
reflections
from
the
dashboard
for
improved
visibility)
and,
most
noticeably,
a
320 mm
(12.6 in)
shorter
wheelbase.
This
was
carried
out
in
order
to
improve
handling
potential
in
the
face
of
newer,
smaller
competition,
such
as
the
Lancia
037
and
the
Peugeot
205
T16,
which
had
been
purpose-built
from
the
start
for
Group
B
rules.
A
total
of
224
cars
of
this
"short
version"
Sport
Quattro
were
built,
and
were
offered
for
sale
at a
heady
price
of
203,850
German
Marks.

Audi Sport Quattro Wiki
The
original Audi Quattro competition
car debuted in
1980, first as a development
car, and then on a formal basis in
the 1980 Janner Rally in
Austria. Largely based on the
bodyshell of the road-going Quattro
models (in contrast to the
forthcoming Group B cars), the
engine of the original competition
version produced approximately 300 bhp
(224 kW/304 PS).
In 1981,
Michèle Mouton became the first
female ever to win a world
championship rally, piloting an Audi
Quattro. Over the next three years,
Audi would introduce the A1 and A2
evolutions of the Quattro in
response to the new
Group B rules, raising power
from the
turbocharged
inline 5-cylinder engine to
around 350 bhp (261 kW/355 PS).
Sport Quattro S1
The
Audi Sport
Quattro S1 was
introduced at the
end of 1984 as an
update to the Audi
Sport Quattro. The
car featured a
inline 5-cylinder
engine that
displaced 2,110 cc
(128.8 cu in)
and produced an
officialy quoted
figure of 350 kW
(480 PS/470 bhp).However,
the
turbocharger
utilised a
recirculating air
system, with the aim
of keeping the turbo
spinning at high
speed, and the
actual figure was in
excess of 500 bhp
(373 kW/507 PS)
at 8000 rpm.[1]
In addition to the
improved power
output, an
aggressive
aerodynamic kit was
added that featured
very distinctive
wings and spoilers
to the front and
rear of the car to
increase
downforce. The
weight was lightened
to just 1,090 kg
(2,403 lb),
and now accelerate
from 0-100 km/h
(62 mph)
in just 3.1 seconds.
Some
of the cars were
supplied with a
"power-shift
gearbox", which is
said to be a
forerunner of
today's
Direct-Shift Gearbox
(DSG) technology.
The
S1 proved to be an
immediate success in
the rally circuit,
helping
Walter Röhrl[1]
and Christian
Geistdörfer win the
1985
San Remo Rally.
A modified version
of the S1, was also
driven by
Michèle Mouton.
The S1 evolution
would become the
final
Group B car
produced by
Audi, with the
works team
withdrawing from the
Championship
following the 1986
rally in Portugal.
Twenty years after
the cancellation of
Group B, the Sport
Quattro S1 was still
widely regarded as
the most powerful
rally car ever
fielded in
international
competition, with
the final factory
machines of 1986
rated at an
incredible 441 kW
(600 PS/591 bhp).
In
addition to Group B
competition, the S1
won the 1985
Pikes Peak
International Hill
Climb with
Michèle Mouton
in the driving seat,
setting a
world record
time in the process.
This victory was
repeated in 1987,
this time at the
hands of
Walter Röhrl,
and again in 1988 (Michèle
Mouton) and 1989
(Bobby Unser),
completing a
hat-trick.
