1985 Audi Sport Quattro S1
The Audi Sport Quattro S1 was introduced at the end of 1985 as an update to
the Audi Sport Quattro. The car featured an inline 5-cylinder engine that
displaced 2,110 cc (128.8 cu in) and produced an officially 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 rpm, when the driver closed the throttle, either to back
off during cornering, or on gearshifts. This allowed the engine to resume
full power immediately after the resumption of full throttle, reducing turbo lag. The actual power figure was in
excess of 500 bhp (373 kW; 507 PS) at 8000 rpm.
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 reduced to just 1,090
kg (2,403 lb), and the S1 could accelerate from 0-100 km/h (62 mph) in just
3.1 seconds. Some of the cars were supplied with a "power-shift gearbox", a
forerunner of today's DSG technology.
The S1 proved to be an immediate success in the rally circuit, helping
Walter Röhrl 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
Twenty years after the cancellation of Group B, the Sport Quattro S1 is
still widely regarded as the most powerful rally car ever fielded in
international competition, with the final factory machines
of 1986 rated at 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.

The struts need to be valved a bit stiffer to help with the squattro action
however weight transfer isn't a bad thing.
