All over the historical past of the game of motor rallying the Workforce B technology could be the maximum dramatic, probably the most intestine wrenching motorsport ever invented.
Some have referred to the Workforce B technology because the “Golden Age of Rallying”, and in all probability it used to be. It used to be in all probability the nearest factor in motor rallying to the mortal fight of the gladiators of Roman instances.
Rapid Information – The Audi Game quattro S1 E2
- The Audi quattro used to be impressed by way of the Volkswagen Iltis 4wd automotive as utilized by the German army.
- The speculation for the primary quattro got here to Audi engineer Jörg Bensinger in 1977 and the primary highway manufacturing automotive gave the impression in overdue 1980.
- The unique Audi quattro centre differential device that enabled the full-time 4wd got here from the Volkswagen Iltis.
- The contest model of the quattro made its debut within the 1980 Jänner Rallye in Austria.
- In 1981 French driving force Michèle Mouton become the primary girl to win a International Rally Championship rally when she drove her Audi quattro to victory within the Rallye Sanremo in Italy.

The Mighty Workforce B Generation
The Workforce B technology used to be lively from 1982 till 1986 when, after a sequence of horrific injuries which incorporated driving force and spectator deaths, the FIA made up our minds to finish it. The generation of the rally automobiles had arguably reached the purpose the place the auto used to be in a position to greater than a human driving force may reliably and safely organize, particularly when looking to cross flat out and keep away from out of control spectators, lots of whom appeared decided to behave like human lemmings.

Workforce B used to be created by way of the FIA (Fédération Internationale de l’Car – the governing frame for plenty of motorsport occasions together with Formulation 1) again in 1982. The speculation at the back of it used to be to supply some flexibility in a collection of motorsport festival laws that may permit producers room for creativity.
To this finish homologation laws have been made some distance much less hard with producers most effective required to make 200 of one of those automotive to go into them in Workforce B: and in addition offering a demand that most effective 10% of that overall had to be if truth be told made for each and every festival yr. So producers most effective needed to produce 20 of those automobiles consistent with yr.
Those laws supplied protection requirements for roll cages and so on, however accredited automobiles to be a lot more robust than had differently been the case.
Producers embraced the brand new laws, and all of the ingenious possible they unleashed, with Audi, Lancia, and Peugeot in particular coming into the spirit of it.
German automotive maker Audi embraced the concept that, for a rally automotive which should navigate regularly unsealed roads at prodigious speeds, that 4wd can be a really perfect merit. This used to be no longer going to be simple to engineer, however Germans, particularly those at Audi, have a deserved recognition for excellence, and they set about making a 4wd device that may be superb for each asphalt and dust.
4wd automobiles weren’t accredited in FIA rallying at that time however in 1979 Audi approached the FIA to foyer to have it accredited, the FIA agreed and so permission for those automobiles used to be incorporated within the revised laws starting in 1980. Volkswagen entered a staff of Iltis within the 1980 Paris-Dakar Rally and controlled a startling 1st, 2d, 4th, and ninth end.

Audi had advanced the quattro within the years prior to Workforce B used to be invented: the automobiles first showing in 1980 as manufacturing automobiles for highway use, with the plan to make use of them in rallying. The unique thought to create this complete time 4wd automotive got here from Audi engineer Jörg Bensinger who learned that the 4wd Volkswagen Iltis (utilized by the German army) used to be in a position to nice roadholding on dust and snow.
The Iltis used to be after all no longer distinctive, for instance the 4wd Ford Bronco had additionally proved the idea that after they have been entered in such motorsport occasions because the Baja 1000 again within the 1960’s.
Audi’s engineers based totally their new consistent 4wd transmission at the Volkswagen Iltis device and fitted it right into a changed Audi 80 with an extended wheelbase. The ability unit used to be the 5 cylinder turbocharged engine that may later in finding its approach into the Audi 200.
The device used to be christened the “Ur-Quattro” (i.e. unique Quattro): and it made its rally debut within the 1980 Jänner Rallye in Austria, all “quattro” automobiles that adopted would use a decrease case “q” out of deference to the unique automotive.
The next yr, 1981, French driving force Michèle Mouton made historical past when she drove an Audi quattro to win a International Championship rally, the Rallye Sanremo in Italy. The quattro thought had confirmed itself and the method of refining and making improvements to it lay forward.
Those first Audi quattro automobiles have been the A1 and A2 that have been according to the common manufacturing Audi quattro fashions on sale in Volkswagen/Audi dealerships. Those automobiles in rally trim have been homologated in Workforce 4 for the 1981 festival season and what then proceeded used to be a “trial by way of fireplace” with drivers struggling with to control the front-heavy weight distribution mixed with the turbocharged inline 5 cylinder engine sending 350 hp to the wheels.
Added to the dealing with problems have been reliability problems with disasters within the mission-critical centre differential being in particular tricky to handle, the restore groups would regularly no longer attempt to restore the misguided differential however merely disconnect it. This used to be no longer an exquisite method to the issue as the motive force then needed to take care of the entrance heavy automotive with out the good thing about the rear wheels being pushed.

Regardless of the demanding situations Audi completed up in 5th position in that yr’s International Rally Championships which confirmed the promise of the quattro thought, making the blood, sweat, tears and frustration generated by way of the generation value it, for the teachings discovered have been to be carried out to perfecting the generation – one thing that may cross directly to grow to be and re-define the rally automotive.
In 1982 with the creation of Workforce B Audi endured with the A1 after which A2 quattro, successful 3 international rallies in 1983 and 5 in 1984 with those automobiles.
In 1984 the made of Audi’s engineering analysis and analysis ended in the advent of the Audi Game quattro S2 constructed on a miles revised design. The auto used to be powered by way of a DOHC double valve (i.e. 4 valves consistent with cylinder) 2,133 cc (2.1 litre) model of the Audi inline 5 cylinder engine. The gas used to be fed into the engine by way of a Bosch LH Jetronic gas injection device mixed with a KKK K7 turbocharger. In Workforce B festival shape this engine churned out a decent 444 hp.
As a way to support the ability to weight ratio the contest automotive’s frame shells have been fabricated from carbon-kevlar with one inch wider wheels (from 8 inch to 9 inch) and tyres, and prolonged wheel arches to make room for them.
At the request of the drivers the windscreen rake used to be steepened to scale back inside reflections from the dashboard, and, oddly given the entrance heavy dealing with of the auto, a 12.6 inch shorter wheelbase.
This nippy little bobtail of a automotive used to be utilized by Michèle Mouton in her attack at the 1985 Pikes Top World Hill Climb. Mouton gained the development, changing into the primary girl to take action, and set a brand new document within the procedure.

The Audi Game quattro S1 E2 Workforce B
The quattro S1 E2 automotive for Workforce B festival used to be according to the S1 however handled to vital aerodynamic frame enhancements, and to an important spice up in energy. The aerodynamic enhancements incorporated very function air-dam and wing on the entrance and a wing on the rear. Those have been put in to a great deal support the downforce performing at the automotive to make it as solid as conceivable each for top velocity and cornering drive.
The spice up in energy for the S1 E2 Workforce B automotive partly got here from revisions to the turbocharging device. The two,110 cc engine used a recirculating air device within the turbocharger to scale back the turbocharger lag, making the engine’s reaction a lot more rapid. The claimed energy output of the engine used to be 473 hp whilst the true determine used to be round 493 hp @ 8,000 rpm and that regularly greater till it used to be extra like 550 hp, at which level the S1 E2 may venture itself from status to 100 mph in a neck muscle straining 8.9 seconds.
The burden of the auto used to be diminished down to one,090 kg (2,403 lb) and so the efficiency advanced, status to 60 mph used to be achieved in 3.1 seconds. Indisputably the aerodynamic wings brought about some further wind resistance however the building up in energy would have compensated for that well.
The entrance to rear stability used to be additionally a lot advanced with the relocation of the radiator and fanatics to the rear, and by way of the huge rear wing which generated a welcome aerodynamic down-force to higher stability the auto.
The quattro S1 E2 Workforce B automobiles gained the 1985 Rally Argentina with 1984 International Champion Stig Blomqvist riding, and the 1985 San Remo Rally gained with Walter Röhrl and Christian Geistdörfer riding.

1986 used to be the remaining yr of Workforce B festival and after that the ones few Workforce B quattro S1 E2 festival automobiles have been bought off to creditors and to these short of automobiles for different kinds of festival. Of the twenty S1 E2 automobiles made fifteen are identified to nonetheless exist. Simplest six if truth be told competed in International Rally Championship occasions, and of the ones six simply 4 are within the ownership of personal fanatics.
