Paolo Stanzani prepared two special cars in 1976, with engine revisions up to 400 bhp, and used the then new Pirelli P7 tires,
the first (nr.188) was finished in a bright red, with a black interior and was delivered to an Italian customer,
but the second, finished in a brilliant Bugatti light-blue, with a natural leather upholstery with gold colored
wheels and pinstriping became the famous Walter Wolf Countach. This specific car, nr. 202 was recently restructured
by the factory and it still wears the original colors.
These two cars were in fact the prototypes of what later would be developed into the Countach LP400S production model.
The LP400S was the first revision of the Lamborghini Countach, the differences between the LP400 and the LP400S
were not only visible on the outside, although that's where they were most obvious, but the entire suspension geometry
had to be redone to cope with the very wide rear wheels.

Walter Wolf could actually be held responsible for the LP400S to be launched by Lamborghini, he had two of his cars
equiped with a custom built 5.0-Litre engine, just like the one Bob Wallace blew up in 1971, but what was more important,
he also had wider Pirelli P7 tires installed on these cars, and had the complete suspension geometry redesigned by Dallara.
When he bought his third personalized Countach, he convinced Lamborghini SpA to take a look at commercializing 'his' modifications.
But they didn't follow the Walter Wolf 'treatment' completely, the wide Pirelli low-profile high-tech P7 tires were adopted,
now mounted on new five-hole telephone-dial rims, as seen on the Bertone's Bravo show car in 12 inch width over a 15 inch height.

To be able to fully use the extra grip of these tires, Dallara had to come back to Lamborghini SpA and completely redesign
the suspension, because of the massive width of these tires it was necessary to keep them as horizontal as possible
on the tarmac.
To complete the exterior changes, four large fiberglass wheelarch extenders were installed, the front
ones connected by a deep chin spoiler, while the rear wing wasn't available at the start of the LP400 S production,
note that the 3rd Wolf car didn't have the rear wing on the Geneva car show, it was mounted later, after he took
delivery of the car.
Demand for the LP400 S increased and also the rear wing seen on Wolf's cars became a highly requested item, later
Lamborghini SpA was forced to offer it as on option on the Countach, at first it was a large wing mounted on two
vertical fins, later two endplates were added at the outer limits of the wing.
All these appendages, together with a slight decrease in engine power to 352 Bhp, to make the Countach easier to handle,
made the LP400S slower than the LP400, therefore Lamborghini decided to keep the LP400 in production along with
the new S-type.
It is noteworthy however that some LP400 S still had the LP400 engine with 375 Bhp the original Weber carburettors with
the high lift camshafts and higher compression, without any emission equipment, while later on most cars imported into
the United States had to be 'federalized' and power dropped even further to 325 Bhp.
All the special tacked-on items made the bodywork less aerodynamic, but the Countach now looked even more aggressive,

ready to tear the road to pieces with it's ground-hugging front spoiler and the widest tires in existance
(345mm width still remains the widest available, even today) mounted at the rear.
The suspension was later raised three centimeters, because most customers damaged the deep front spoiler,
hitting the sidewalk with it, also during the 1981 production run, the wheels were changed to a simpler design,
which would be used up to the LP 5000 QuattroValvole, also note the first 24 cars had magnesium wheels, which in
the late Seventies were about US $ 2000 each, later the wheels were made of aluminium, which were actually a lot
cheaper than the exotic magnesium ones, and the suspension was modified with new shock absorbers, way Assauto.
At that time the dashboard was also changed, and bigger Jaeger instrumentation (the LP400 used Stewart Warner ones)
was installed, the speedometer now started at 20 km/h instead of 40 km/h as on the earlier ones, also different
steering wheels were mounted during the LP400 S production.
The roof was raised another three centimeters on the inside, starting from chassis nr. 1121312, to improve the comfort of taller driver,
but still nobody taller than 180 cm would fit into the tight cockpit, the tunnel in the roof, which the
LP500 used for its rear view mirror, was actually removed and provided this three cm extra space.
The accelerator pedal was now hinged from the top and the handbrake lever was moved to the right of
the driver.
On the 1979 Frankfurt Auto Show, a silver-grey Countach was displayed with new, rectangular
rear view mirrors, which would be installed on several cars. Next to this car was a turbo-charged V-12 engine,
but it was actually only a mock-up, it was never functional, and the Lamborghini factory never produced a
turbo-charged Countach.
Also note that the moment the LP400 S was available for sale, the demand of the original LP400 dropped dramatically,

and a new demand was unintentionally created by Lamborghini SpA, several owners of the LP400 Countach wanted to have
their car turned into an S-series look alike, now here things start getting complicated, some LP 400's got the
front spoiler and wheel arch extension, but not the expensive wheels and different suspension, while other LP400's
were 'retrofitted' with the entire S-series options.
Also the factory was persuaded by several wealthy customers to convert brand new LP400's into the LP400 S model,
complete with front spoiler, wheel arches and massive rear wheels with the special setup suspension, but
these cars still had the 375 Bhp engine as mentioned earlier, so these would easily outperform any 'original'
LP400 S on the open road.
