| - The Aston Martin DB3S is a sports racing car that was built by Aston Martin. Following the failure of the heavy and uncompetitive Aston Martin DB3 designed by Eberan Eberhorst; William Watson, employed as Eberhorst's assistant, presented an alternative design to John Wyer, Aston Martin's competitions manager, whose assistance was needed as Eberhorst could well oppose being up-staged. In total 31 cars were made, with 11 works cars and 20 cars being sold for customer use. The DB3S was introduced in 1953 and it proved significantly more successful than the Aston Martin DB3. Although the DB3S failed at Le Mans they went on to score a 1–2 at the Tourist Trophy at Dundrod in the 6th round of the inaugural World Sports Car Championship to help Astons to 3rd in the championship. As well there was a win in the non championship Goodwood 9 Hours. 1954 was a less successful season with a third place in the Buenos Aires 1000 km being the high point. However the cars failed at the Sebring 12 hours, the Mille Miglia, Le Mans and the Tourist Trophy. 1955 saw a return to form. Astons missed the opening two rounds at Buenos Aires and Sebring and the sole DB3S failed to finish at the Mille Miglia but Collins/Frere finished 2nd at Le Mans and Walker/Poore scored a 4th at the Tourist Trophy behind the dominant 1, 2, 3 of the Mercedes 300SLR to finish 5th in the championship. There was also time for another win in the non championship Goodwood 9 Hours. By 1956 the design was starting to show its age and Astons were putting their resources into the development of the new DBR1 but the DB3S still finished 4th at Sebring and 5th at the Nurburging 1000 km to finish 4th in the championship together with another second at Le Mans in the hands of Moss/Collins although due to the change of regulations following the 1955 disaster this latter event was a non championship race. The DBR1 now took over as Astons main sports racer, but there was one last swan song for the DB3S in the hands of the Whitehead brothers at Le Mans in 1958 with a second place after all the works DBR1s failed to finish. The car won the 2013 Gran Turismo Trophy at Pebble Beach Concours d'Elegance. (en)

Au total, 31 voitures ont été fabriquées, dont 11 voitures usines et 20 voitures clients. La DB3S a été présentée en 1953 et s'est révélée significativement plus efficace que la DB3. Bien que les DB3S aient échoué au Mans, elles réussirent un doublé au Tourist Trophy de Dundrod lors de la 6e manche du premier Championnat du monde de voitures de sport, aidant Aston Martin à se classer 3e du championnat. De plus, elles remportèrent une victoire hors championnat lors des . En 1954, elles connurent une saison moins bonne avec une troisième place aux qui fut leur meilleur résultat. Les voitures échouèrent successivement aux 12 heures de Sebring, aux Mille Miglia, au Mans et au Tourist Trophy. 1955 fut un retour des performances. Les Aston Martin ratèrent les deux premiers tours à Buenos Aires et à Sebring. L'unique DB3S engagée aux Mille Miglia ne réussit pas à terminer la course, mais l'équipage Collins/Frere termina 2e au Mans et Walker/Poore remporta une 4e place au Tourist Trophy, derrière les intouchables Mercedes 300 SLR aux trois premières places, ce qui lui permit de terminer 5e du championnat. Il y eut aussi une autre victoire hors championnat aux 9 Heures de Goodwood. En 1956, la conception de la voiture commençant à dater, Aston Martin mit ses ressources dans le développement de la nouvelle DBR1 ce qui n’empêchât pas la DB3S de terminer 4e à Sebring et 5e aux 1000km du Nurburging. La voiture termina 4e du championnat avec une seconde place au Mans entre les mains de Mousse/Collins, bien qu'à la suite de la catastrophe de 1955 et en raison de la modification de la réglementation, cette dernière course n'ait pas compté pour le championnat. Pour Aston Martin, il était temps pour la nouvelle DBR1 de prendre le relais en sport. Pourtant, la DB3 réalisa encore un dernier exploit lors des 24 heures du Mans 1958 entre les mains des frères Whitehead, remportant la deuxième place après que toutes les DBR1 usines aient abandonné. La voiture a remporté le Gran Turismo Trophy 2013 au Concours d'Elegance de Pebble Beach. (fr)
- La DB3S è un'autovettura da competizione prodotta dalla Aston Martin dal 1953 al 1955. Il modello derivava dalla Aston Martin DB3 e dei 31 esemplari realizzati, 11 furono destinati alle gare, mentre 20 vennero venduti a clienti privati. Degli 11 esemplari destinati alle competizioni, solo 10 furono poi realmente impiegati dall'Aston Martin. La DB3S fu sostituita, nel 1956, dalla DBR1. Il telaio era tubolare doppio e separato, mentre il corpo vettura era aperto e venne realizzato in alluminio. Le sospensioni erano costituite da barra di torsione, doppi bracci oscillanti e ponte De Dion posteriore. Il motore era anteriore ed aveva una configurazione a sei cilindri in linea. La cilindrata era di 2.992 cm³. Questo propulsore era dotato di tre carburatori doppio corpo Weber 35 DCO e di una distribuzione a doppio albero a camme in testa. Il cambio era un "David Brown S430" manuale a quattro rapporti mentre la frizione era monodisco da 9". La trazione era posteriore. Due esemplari di DB3S destinati alle gare vennero realizzati con carrozzeria coupé. Questo corpo vettura risultava più aerodinamico di quello aperto. In ogni caso, questi due esemplari erano instabili alle alte velocità e quindi si schiantarono entrambi alla . In seguito, dopo l'incidente, questi due modelli vennero ricostruiti con una carrozzeria aperta. Anche tre degli esemplari di DB3S destinati alla clientela privata furono dotati di carrozzeria coupé. Questo modello non ebbe molto successo nelle gare. (it)
