Piccolo ma Potente - Abarth 1000 SP

Image
  Courtesy of Tony Berni Carlo Abarth’s manager of mechanical, chassis and body development , Mario Colucci, joined from Alfa Romeo following the collaborative Abarth-Alfa 1000 project which culminated in November ’58 with the presentation of a Scaglione-styled version at the Turin Motor Show.  This model featured a tube frame chassis, the preference of both Alfa Romeo corporately, and Colucci personally.  Following on from this, despite his own contrary chassis construction and engine location principles, Carlo Abarth gave Colucci the opportunity to design and develop a new line of lightweight spiders, initially with the Fiat 600-based 748 cc #221 engine.  By ’62, 1300, 1450 and 2000 cc versions had evolved, utilising the Simca-based engine.  However, these models did not achieve competitive successes to an extent which could attract an ongoing/increasing cohort of racing customers.  In addition, Carlo’s retained prejudices re-emerged in an edict which contended that the expense invol

The Nearly Alfa - Part 2

Once again, the control of Alfa Romeo by the state organisation, Istituto per la Ricostruzione Industriale – IRI – through its finanziaria, (financial entity), Finmeccanica, would be highly influential.  Not for the first time, the managements of Alfa Romeo and Autodelta were compelled to make decisions constrained by directives formulated on the basis of political expediency rather than engineering savvy.  Responding to recurrent government diktaks seeking to promote the use/consumption of Italian-made products, Finmeccanica ‘s nose intruded into the 890 engine project, stipulating that its turbochargers must be locally-sourced.  Accordingly, the KKKs were soon replaced by units made by the Alfa Romeo aeronautical manufacturing subsidiary, Avio.  Unfortunately, the performance and reliability of these was clearly inferior to the German blowers.  At this stage of the 890’s development, the induction characteristics were rendered furthermore problematic by the difficulty found in the se

Eight on the way to Twelve – the Abarth V8 Engine

Image
Much was positive for Abarth as 1965 dawned.   Especially so in terms of the marque’s racing exploits.   For three years in succession, Abarth had taken GT World Championship honours, in the 1 litre class in ’62, 1.3 in ’63 and ’64.   In addition to these top-flight achievements, Abarth victories in national, regional and club events were commonplace, providing the Corso Marche treasury with regular and substantial income stemming from the ‘57 agreement whereby Fiat made a payment to Abarth for each and every race win credited to one of its Fiat-based models.   But there was a downside to this apparently generous, sugar daddy arrangement – to maintain the competitiveness of Abarth’s numerous racing customers, across a wide spread of model types/variants, it was necessary to implement an ongoing programme of product development and resulting upgrades.  This was an expensive business – enough so to be prompting Carlo Abarth, Renzo Avidano and Carlo Scagliarini to consider a major str
