Sirron Cars

Sirron Cars was a short-lived English automobile marque whose cars were manufactured at York Works on South Road in Southall, Middlesex, between 1909 and 1914. The company produced a range of passenger cars with stated outputs from 10 to 25 horsepower, placing the marque within the broad field of early British motor manufacturing rather than the specialist or luxury segments for which some contemporary manufacturers became known. A representative Sirron was reported to cost approximately 200 guineas, providing an indication of its position in the early twentieth-century British car market, although the available reference material does not identify a complete model catalogue, production totals, sales network, or surviving corporate structure. Sirron therefore appears to have been a small and comparatively obscure marque whose principal historical significance lies in its documented place within the early Southall automotive industry. Production ended in 1914, around the beginning of the First World War, but the available sources do not establish whether wartime conditions, commercial difficulties, or another factor directly caused the cessation. The Sirron name later appeared in connection with diesel engines associated with the Newbury Diesel Company. Those engines were designed by Henry Kent Norris, and the name Sirron was formed by spelling Norris backwards. Norris was a racing motorist who competed in Tourist Trophy events before the First World War and died in 1969. However, the reference material does not establish that Norris was connected with the earlier Sirron car manufacturer, so the later diesel-engine usage should be treated as a subsequent association rather than evidence of common ownership or continuity. No reliable information is provided on a present owner, successor company, headquarters, website, executives, export markets, or current commercial activity. Sirron Cars is consequently best classified as a defunct historical British automobile brand.

Sirron Cars operated from York Works on South Road in Southall, Middlesex, England. Its documented production period ran from 1909 through 1914, during the formative phase of the British motor industry, when numerous small manufacturers attempted to establish themselves by producing comparatively low- or medium-powered cars for the domestic market. The available historical account records several Sirron models with outputs ranging from 10 to 25 horsepower. This range suggests that the marque served more than one segment of the early passenger-car market, but the surviving reference does not provide model names, body styles, engine specifications, production volumes, or details of the engineering design. A typical car was priced at about 200 guineas, although the exact model and date associated with that figure are not specified. Sirron’s manufacturing base at Southall places it among the early automotive enterprises operating in the London and Middlesex industrial environment. Its production ended in 1914. The source does not state whether the end of production resulted from the First World War, financial pressure, acquisition, or a planned closure, and no successor automobile business is identified. The Sirron car marque should therefore be regarded as defunct from 1914, with its surviving documentation limited largely to its location, operating dates, power range, and indicative price. A separate later use of the name is associated with the Newbury Diesel Company. Diesel engines carrying the Sirron name were designed by Henry Kent Norris, whose surname was reversed to create the name Sirron. Norris was a racing motorist who competed in Tourist Trophy races before the First World War and died in 1969. The available account explicitly leaves open whether Norris had any connection with the earlier Sirron car manufacturer. On the evidence provided, the later diesel-engine name cannot be treated as proof that the automobile marque continued under the same ownership, technology, or corporate identity. No current business activity, surviving product line, parent company, or modern brand management is documented.

  Sirron diesel engines

  The Sirron name was later applied to diesel engines associated with the Newbury Diesel Company. These engines were designed by Henry Kent Norris, and the name was derived by spelling Norris backwards. The available material does not provide engine specifications, production dates, applications, or evidence that this later diesel-engine usage was controlled by the original automobile manufacturer.
