The ASA 1000 GTC was a sports racing car built in 1963 by [[Giotto Bizzarrini]] and based on a production 1000 GT. The car was developed under a newly-founded Società Autostar workshop. The body was designed and built by [[Piero Drogo]]'s [[Carrozzeria Sports Cars]]. The engine had its displacement reduced to 995 cc to meet the under 1.0-litre racing classification. The tubular chassis with aluminium body saved the weight to a total of {{Convert|590|kg|lb|abbr=on}}. Bizzarrini and Drogo also built a larger displacement car called 1300 GTC with 1.3-litre engine that debuted at the 1966 [[Trento-Bondone Hill Climb]].<ref>{{cite web|url=https://www.coachbuild.com/2/index.php/encyclopedia/coachbuilders-models/item/drogo-asa-1000gtc-010-1962|title=Drogo ASA 1000GTC #010 1962|website=coachbuild.com|access-date=24 November 2019}}</ref>

This engine produced {{convert|104|bhp|kW|abbr=on}} at 7500 rpm. The Berlinetta 411 had a lightweight all-aluminum body and [[Poly(methyl methacrylate)|plexiglass]] windows, resulting in a dry weight of {{Convert|1562|lbs|kg|order=flip}} compared to the regular 1000 GT's {{Convert|1720|lb|kg|order=flip}}.<ref name=":1" /> Other modifications included wider tires and a competition gas filler.<ref name=":4" /> The exact number produced is unknown.<ref name=":4" /> Two competition 1000 GTs were entered in the [[1965 Targa Florio]].<ref>{{Cite news|url=https://www.motorsportmagazine.com/archive/article/june-1965/13/49th-targa-florio|title=THE 49th TARGA FLORIO|last=Jenkinson|first=Denis|date=1965-06-01|work=Motor Sport Magazine|access-date=2018-09-26|page=13|language=en}}</ref> They placed 17th and 22nd overall, 3rd and 4th place in the 1000-1600cc prototype class.<ref name=":4" />
