Alvis 10/30

The Alvis 10/30 was the first production car of the Alvis Car and Engineering Company, introduced in 1920 and made until 1923. It had a water-cooled four-cylinder engine of 1,460 cc, usually of side-valve type though some had overhead valves, driving the rear wheels through a cone clutch and four-speed gearbox on a chassis with rigid axles and half-elliptic springs. A range of body styles was offered, and a top speed of 60 mph was claimed, with an overhead-valve Super Sports version said to lap Brooklands at 80 mph. The chassis cost 450 pounds, rising to 470 with a factory body. A larger 1,598 cc engine arrived in 1921 as the 11/40, later the 12/40.
