Vehicle Description
Autodelta Factory Team Race Car, Raced 24 Daytona 1968
FIA Passport, Moda Miami Concours Class Winner 2025
In 1965 Alfa Romeo and its racing arm Autodelta introduced its new
entry to the European Touring Car Championship. The new GTA or Gran
Turismo Alleggerita was a comprehensively modified production
Giulia GT and homologated by the FIA with approximately 500
examples completed. Wearing a full aluminum body and replete with
the latest performance modifications developed by Autodelta ,
including twin plug cylinder head and magnesium everywhere, earning
its appellation "Alleggerita" or light weight. Fast out of the box,
Autodelta and many privateers used GTAs to make names for
themselves in the racing world both in Europe and in the TransAm
series in the US. The drivers who raced and won in GTAs reads like
a who's who of competition in the 60's. De Adamich, Kwech, Giunti
and Jochen Rindt to name a few.
Manufactured by Alfa Romeo in July 1965 and delivered new to the
Senegalese importer. In 1968 613760 Contested the 24 Hours of
Daytona entered by the official Alfa Romeo works team; Autodelta.
Driven by regular Autodelta team drivers, Teodoro Zeccoli, Leo
Cella and Gianpiero Biscaldi, it finished a very credible sixth in
class and twentiet overall. After its use as an Autodelta Team Car,
613760 quickly found its way into the hands of Franco Angelini, the
well-known and respected Roman Alfa Romeo tuner whose semi works
cars were always front runners either harrying or beating the
Autodelta cars.
Finished in its 1968 24 Hours of Daytona livery 613760 is fresh,
race ready and set up for US Historic racing with a freshened up
175 HP motor and a close ratio gearbox, 613760 is in original
specification and comes with a complete history file, FIA HTP
(Historical Vehicle Passport), Italian CSAI Logbook and continuous
Italian vehicle registrations to its first registration in the name
of Franco Angelini. Additionally, a complete sliding block (or
"Slittone") rear suspension system is available for a US based
Historic racer. Currently it is running the standard GTA rear end,
legal in European events. Ready to be driven and be competitive in
any of the important Historic events such as Le Mans Classic,
Goodwood, and the Tour Auto. With little modification, it would
make a marvelous car for road tours or Rallyes such as The Colorado
Grand or Copperstate 1000.
