Geoffrey de Freville designed the first Alvis engine and is also responsible for the
company name. Production was in Coventry, where from 1922 to 1923 they also made the Buckingham car.
De Freville's first engine design was a four cylinder engine with aluminium pidstons and pressure lubrication, which was unusual for that time. The first car model using de Freville's engine was the Alvis 10/30. It was an instant success and established the reputation for quality workmanship and superior performance for which the company was to become famous. The original 10/30 side-valve engine was improved, becoming by 1923 the overhead valve Alvis 12/50, a highly successful sports car that was produced until 1932. Around 700 of the 12/50 models and 120 of the later Alvis 12/60 models survive today.
1927 saw the introduction of the six-cylinder Alvis 14.75 and this engine became the basis for the long line of luxurious six-cylinder Alvis cars produced up to the outbreak of the Second World War. These cars were elegant and full of technical innovations. Independent front suspension and the world's first all-synchromesh gearbox came in 1933 followed by servo assisted brakes. The Alvis 12/75 model was introduced in 1928, a model bristling with innovation, such as front wheel drive, in-board brakes, overhead camshaft.
