The Abarth in the running-mission

rally | upgraded | swan song | works-racer

  In October 1972 the brand-new Abarth race versions strong from the beginning of 165 HP were operational. They   became free for running only at the end of of 1972. It's Rally premiere committed the CSA under Alcide Paganelli   and Domenico "Nini" Russo with the TAP Rally Portugal in the prototype class (group 5). A defective gasoline pump   threw them on the fifth place back.

  In relation to the civil remarks at the racers lightly on 950 Kilos they had   done infinitely much. "Tuned and improved" was called it so beautifully in   the Homologations regulations of the group 4 (500 cars).

  The meant: Achievement-increasing cylinder heads and engine mounts   including larger valves and harder valve seat feathers/springs were just
  as legal, as special cranking and cam shafts; Lubrication system, mixture   preparation and exhaust organization were subject only to few obligations.

  The compression rose by means of higher, forged piston on up to 12,5:1,   the anyway extraordinarily stable crank gear became more low-friction;   they seized to sturdy titanium piston rods. An oil-cooler associated to the   water-cooler too, the oil pan was increased and the achievement of the oil   pump increased. Those "sharp" cam shafts through still "sharper"   replaced, which became suction ports increased, hollow or sodium-cooled   valves were anyway already used. All in all engine performances were so   finally realized by approximately 165 HP with 7200 U/min - this meant 5.2   kg/HP weight per horsepower instead of 7,2 kg/HP with the series Abarth.

  The over-powerful 1,8-Liter-alpine-rivals had itself however just on the same maximum speed "high upgraded".

  Again of Colotti the unsynchronal, extremely durable, but fine-coordinated CCC-5 gearbox (CCC = Cambio Corsa   Colotti) came - also the transmission choice was released by the FIA: Had to be free however 100 pieces.

  The balanced-T section was run-moderately laid out: The first course sat completely at the bottom left hand corner,   on one level with the reverse gear.

  The slip differential came also from Colotti with a lock percentage of 25 up to 100 percent. Still another difference   with the series CSA: The screwsteering was laid out, those for front axle was continued to modify with 12:1 instead   of 16:1 many more directly. And the Hardtop consisted - in contrast to the civilian CSA - of breath-thin fiber glass.

  In the inside did not do so much; in the light aluminum dashboard however only the tachometer sat, surrounded by   4 smaller round instruments.

  Naturally also the flared wings had still more sumptuously   failed. A half year later experimented Abarth with still much   more aerodynamics aids: The broadly issued spoilers in   extension of the flared wings within the tail range worked like   batwings...

  In addition on the racing course by Casale a strong 2,0-litre   Abarth engine from the racecar Abarth Osella 2000 was mounted   for 250 HP by way of trial.

  Lively realized by the Abarth testdriver, Giorgio Pianta (today Alfa race-chief in the ITC) and of Ingeneur Piero   Jacoponi the vehicle in the middle of 1973 one finished and one used successfully with still more unloading tail   wing work with the 1973er giro d'Italia. Although there were no further employments, this combination had not by any   means coincidentally come off: Already with a press conference at the end of 1972 had announced, project manager   Gianfranco Squazzini, not only the new CSA, but also had placed future co-operation with the Osella raceteam in   prospect.

  They hoped to show 1973 in the sport prototype class of the two-litre cars of the competition the exhaust - it left   however during this declaration of intent.

  Starting from January went to that yearly instead of its four work-crews with that to durable Group-4-Abarth into   running. The whole year 1973 over remained its colour the same: red basic colour, flat black hoods, black flared   wings, summer white roof (otherwise black Hardtop) and white sidestripes.

  For the first time they were used directly with the 42. Rally Monte Carlo. Also with it were of now on also some the   Scandinavian world class pilots such as Bjoern Waldegaard and Rauno Aaltonen, which one had bought as heavily   doped Freelancer. With the Monte drove the Fiat teams against hardest competition - against the previous year   winners, the Lancia Fulvia 1600 HF, and the Renault Alpine's.   But the employment was only one disaster: Bjoern Waldegaard   separated early, Paganellis car smashed at a wall, Raffaele   Pinto/Pietro Bernacchini became only seventh. Also with the   Sweden Rally no headlines were written: Lindberg/Andreasson   came only on fifth rank. And in May with the Morocco Rally   proved the 124-Abarth-chassisframe as not sufficiently, and   Waldegaard/Sager became only sixth.

  Fortunately 1973 also some laurel could be achieved. High point   was, when Achim Warmbold and Jean Todt (the today's Ferrari   running leader in the formula 1) came as first from 3 "survivors"   Equipes with hard Poland Rally into the goal: 62 teams were   failed... Aaltonen/Turvey occupied with the Akropolis Rally the   second place, Lindberg/Hertz became fourth. Verrini/Torriani   came with the Rally San Remo on second rank, further three Fiat teams followed them on the foot. Achim Warmbold   achieved the respected place with the thousand lakes Rally however only.

  And the coronation was, when Fiat became 1973 vice-mark world champions - this time after alpine-renault & before   Fords, Volvo and Saab. Too does not forget the lady European championship, where the earlier Porsche-911-pilots   Donatell Tominz/Lucia Mamolo ("Squaw") on Fiats made the run.
