Brough8 HP Monocar
Final named light-car program of William Brough's firm, using the proprietary 8 hp V-twin developed alongside the 6 hp motorcycle engine. The period-derived name Monocar is retained, though surviving summaries do not establish whether its layout had three or four wheels, nor preserve body, wheelbase, transmission, final drive, price or customers. It is not the ladies' open-frame 3½ hp motorcycle mentioned in the same 1912 range. Automobile manufacture ended by 1913, while Brough motorcycles continued into the mid-1920s.
Dates with their meaning intact
This record contains useful sourced evidence, but it does not yet meet the reference-ready standard. Still needed: attributed imagery. Fields we cannot source stay empty rather than guessed.
A few Brough automobiles were built through 1913; no Monocar-specific chassis total survives.
