it was Only manufactured 200 copies.
Group B was one of the most spectacular formulas used in the entire history of the competition. Much more permissive than the Group 4 which replaced, allowed the different manufacturers only had to fabricate a series of 200 copies to be able to homologate the model, compared to the 400 required by the Group 4.
This allowed the brands involved, especially in the various championships of rallies, create authentic prototypes that had little or nothing to do with the models of street that are intended to emulate the lids of your body. In the edition 2017 of Villa Erba, you will find available for two of the models most significant, the Audi Sport Quattro and Lancia Delta S4.
If the model of Audi was the a pioneer in incorporating the all-wheel drive system, which quickly became the standard of the category, the Lancia was one of the last and more radical models that are created for this formula, which quickly had to be cancelled because of the incredible level of potential mechanical reached by the participants in a very short time.
The Delta S4 Group B is a machine, bestial, even under the current standards.
Morphologically speaking, the Group B rally championship is not derived from vehicles of street, contrary to what you may be used up to that time. Many of them, though from the outside we remember the models of the grantee, were manufactured with ligerísimos racks created ex profeso for these prototypes, with schemes of central motor wildly sobrepotenciados and all-wheel drive. Their versions of “street” were usually versions decaffeinated mechanically, so that the few manufactured units are still models extremely radical, now adored the parts of the collection.
The Lancia Delta S4 Stradale only had as a purpose to be able to homologate the Delta S4 in the Championship of the World Rally championship (S for supercharged and 4 of 4-wheel drive), and although it was intended to emulate the Delta street with the shapes of your body, what is true is that could not be more different. Of there that to the naked eye looks like a bad copy of the Delta series, because their proportions are very different.
Their lengths are different, 3.885 mm for the Delta street in front of the 4.005 mm version S4 Stradale, and its proportions are somewhat different, with a line of passenger compartment is shorter in the case of the S4 and a little less height.
Mimics the Delta of the first generation, but it is very different.
As the racing car, the S4 Stradale were manufactured
around a tubular frame made with tubes in chrome molybdenum and
with sub-frame of aluminum. The 4-cylinder engine and 1.8-liter was
hosted at the centre and account with the compressor volumetric and turbocharger, in addition to
In your version Stradale, the S4 delivered a few 250 HP
and 291 Nm rising out of the (officially) up to about 450 HP in the version
of competition, although it is well known that in its latest developments
surpassed the 550 horsepower. The transmission was manual and its awd system I had 3 differentials, that were handing out the pair in a 30/70 per cent to the axles front/rear respectively.
The body were simple caps of glass fibre and epoxy, and while the racing model weighed less than 900 pounds, versions Stradale reaching the 1,200 kilos. This was mainly the equipment, because in the inside we find an interior completely covered in Alcantara, plus items such as power steering, air conditioning, or even a rudimentary on-board computer.
Even the decaffeinated version Stradale is terribly radical.
Just came to make the 200 units required for the
approval, and this copy of red came out of the factory in
1985. You currently have in your bookmark of only 1,600 km,
which is not unusual in a vehicle of this type, since they have been part of
collection from your own birth. This piece has a
quote that points between 450,000 and 550,000 euros.
Lancia declared a maximum speed of 225 km/h and a number of 6 seconds to complete the 0 to 100 km/h, figures which may seem a bit spectacular for a sport today, but let us remember that we are talking about a model with more than 30 years old and most importantly, a version deliberately decaffeinated and civilized model of competition, the purpose of which was to stick to the ground like no other and cope with curve after curve at speeds daredevil for that type of roads and pavements.
One of the best stories of the Lancia Delta S4 (rally) the starred Henri Toivonen onboard a unit with the supercharger regulated to the maximum, with a theoretical 800 horsepower. A few weeks before the Rally of Portugal in 1986, there were a few laps of the test at the Estoril circuit, which at that time was part of the calendar of the F1.
In configurations with more radical boost hiring about 600 HP in rallies.
His best time, he says, it was just a few seconds slower than the
chrono faster obtained only a few weeks before in a test of the
Formula 1 and that would have allowed him to be classified among the ten
first grill of the Grand Prix of that year.
that Is to say, allegedly, your time was between 1:16.673 marked by
Ayrton Senna with his Lotus and the 1:19.657 of Rene Arnoux with a Ligier.
At that time, the F1 even had turbo engines, and that season
the more powerful engines exceed easily 1000 HP. Though
never knew the clock real, this anecdote exemplifies to perfection
the tremendous power of the models of Group B.
