The Adem was an Italian-built car sold on the British market in 1912 by A. De Martini after his departure from the Martini company. Its 17.9 horsepower 4-cylinder monobloc engine had a capacity of 2.9 litres and a four-speed gearbox. It was cooled by fan blades on the flywheel. The car was not commercially successful, and it is possible none were sold.
