The Alvis Speed 25 was a British touring car made between 1936 and 1940 by Alvis Ltd in Coventry. Widely considered one of the finest cars produced in the 1930s it replaced the Alvis Speed 20. The earlier car’s six-cylinder, four main bearing engine was replaced in the Speed 25 with a similarly designed larger six-cylinder in-line unit with seven main bearings for which an output of 110 PS at 3,800 rpm was claimed (and proven) along with a top speed of almost 160 km/h (100 mph). It propelled the occupants at high speed in exceptional luxury accompanied by the attractive sound of a powerful deep and throaty exhaust.
