Lagonda is a British luxury car marque, founded as a company in 1906 in Staines, Middlesex by a former opera singer from Ohio, but of Scottish ancestry, named Wilbur Gunn (1859–1920). He named the company after a river near the town of his birth, Springfield, Ohio, USA. The marque has been owned by Aston Martin since 1947.

Wilbur Gunn had originally built motorcycles on a small scale in the garden of his house in Staines with reasonable success including a win on the 1905 London—Edinburgh trial. In 1907 he launched his first car, the 20 hp, 6-cylinder Torpedo, which he used to win the [[Moscow]-[St. Petersburg]] trial of 1910. This success produced a healthy order for exports to Russia which continued until 1914. In the pre-war period Lagonda also made an advanced small car, the 11.1 with a four-cylinder 1000 cc engine, which featured an anti-roll bar and a rivetted monocoque body and the first ever fly-off handbrake.

The ratchet control button on the end of a fly-off handbrake is designed to work in the opposite way to what is normally accepted. If the lever is lifted or pulled back to the "on" position, on letting go it immediately releases unless the end button is pressed and held in place before letting go of the lever. Once set, the brake is released by lifting the handbrake lever (not pushing the button) in the setting direction (up or back). This mechanism was traditionally fitted to sports cars to facilitate a racing get-away, such as at traffic lights. It can also be used to help the back wheels to slide, without the worry of the ratchet leaving the brake on.
