Sport Quattro S1 'Pikes Peak'

Audi Sport Quattro

Manufactured:
february 1984 - january 1986 (rallye Sport Quattro until 1986)
Engine:
"KW" 2133cc (79.3 x 86.4mm) - 20v - 306hp / 350Nm - 1984-1986
Aluminiumblock and head, 8.1:1 compression-ratio

The fierce competition in Group B in the mid-80s forced Audi to improve
their rallycars. The result was the Sport Quattro, a 320mm shortened
urquattro, more suitable for the twisty bends.
Seriesproduction:
The Audi inline 5 lies far in front of the Quattro vehicles, which gives the
car understeer-characteristics. To improve this matter, Audi shortened
the original Quattro by 320mm from the B-pillar and rearwards.

Other changes was the use of a more upright windscreen (like the typ 81
Audi 80 2-door version) to avoid reflections, a ventilated bonnet and a
onepiece grille in black surrounding the headlamps. All chassisparts were
built especially for the Sport, most of them in lightweight materials. The
exception are the steel doors taken from the beforementioned Audi 80.
Hatch was in glasfibre, while the remaining was by GRP composite.

Evolving - A1 in front, then Sport Quattro and two shortened prototypes

214 Sport Quattros were built between 1984 and 1986, but some were
finished spare chassis' released in 1988. It is the Quattro car that
introduced the 20V engine, while the engineblock is the same found on
the rallye Quattro A2s, in aluminium. These are said to be prone to
cracking, so it is not unusual to find a Sport Quattro featuring the more
standard cast-iron block. If this is an actual problem, or just a way for
Audi Sport to get hold of more aluminium bottomends is uncertain.
Nevertheless, the Sport Quattro is a real driver's car, i.e. right hand
sidemirrors were optinal as it stole 2km/h of the car's topspeed. Other
options were polished Ronal alloywheels.

In streetversion the Sport Quattro delivers 306hp by 6000 rpms.
0-100km/h is done in 4.9 seconds, and topspeed is around 250km/h.

All Sport Quattros features the setup of regular production, that is the
following code: WAU ZZZ 85 ZEA 905***, 128 cars Tornado red, 48
cars Alpein weiss, 21 cars Copenhagen blau and 15 was Malachite grün.
Additional 2 cars was given the special black metallic, as it was
Ferdinand Piech's favourite color (IN-NJ 99 and IN-NY 88).

There are now less Group B rallye Sport Quattros than S1 cars.

All cars had left hand drive to accomodate FIA's homologation demands
of over 200 cars produced. Of the 214 cars was 164 sold to customers,
19 stayed inhouse and 22 dedicated for Audi Sport, 5 as parts cars and
the remaining 6 stayed at Audi AG.

Engine: inline 5, alu-block, alu-head, 20V.
Capacity: 2133cc by bore 79,3mm x 86,4mm stroke
Compression-ratio: 8.1:1
Power: 306hp / 6000 rpms
Torque: 350Nm / 3700 rpms

Rallye production:

Much alike the rallye Quattro A2, besides the shortened chassis and the new
20 valved engine. First used at Corsica 1984 and last at Ivory Coast rally
in 1985, the rallye Sport Quattro had the same displacement as the A2 with
2110cc. It featured approx 400hp by 7500 rpms and 460Nm, with a
compression-ratio of 7:1.

0-100 km/h in 4.4 seconds, weight was 1060kg.
Length/height/widht 4239/1859/1343mm.

Prototype 25V engine, equipped with twin KKK K24 turbos

Audi Quattro S1

Engine:
2110cc - 20v - 450-550hp / 670Nm - 1985-86

Not all the drivers were pleased by the shortened Sport Quattro as a
heritant to the A2, especially Walter Röhrl. In many situations the
predecessor did better than the new car, so Audi had to evolve the
rallye Sport Quattro. The result is the winged Audi rallye Sport Quattro S1.
The big setup of wings in front and rear ment better traction.
First used in Argentina 1985, and last in Portugal in 1986, these cars
present the wildest version of the rallye Quattros. Chassiswise they are
marked independently from the Sport Quattro series. Only 20 cars were
built, whereas the last car was used in regular S1 costume in 1986 at
the Pikes Peak event, and in a more extreme version in 1987 at the
same event.

Engine: inline 5, alu-block, alu-head, 10V.
Capacity: 2110cc by bore 79,5mm x 85mm stroke
Compression-ratio: 7:1
Power: 476hp / 7500 rpms
Torque: 480Nm / 5500 rpms

These engines were built to do 8500 rpms, and features 2.2BAR
from their K27 turbos. Different drivetrains were tested, standard
with 6 speed gearbox with hydraulic operated clutch, but one car
also tested the Porsche Doppel Kupplung (PDK).

Topspeed at approx 220km/h and 0-100km/h done in 3.1 seconds.
Length/height/width 4240/1860/1343mm.

Audi Quattro S1 'Pikes Peak'

Engine:
2110cc - 20v - 598hp/590Nm

After the cancellation of Group B in 1986, Audi searched for another
arena to display it's Quattro cars. The Pikes Peak hillclimb in Colorado was
found the most suitable one.
Michele Mouton raced to victory in 1985 in a rallye Sport Quattro, followed
by Bobby Unser in 1986 in S1 no. 20, and last Walter Röhrl in the evolution
S1 in 1987, setting a new course-record at 10:47.85.

Pikes Peak S1 as few knows it, in regular S1 guise driven by Bobby Unser in '86
