The Alvis Speed 25 was a British luxury touring car manufactured in 1937-1940 by the Alvis Car and Engineering Company. It replaced the Alvis Speed 20 and was considered one of the best cars produced in the 1930s.
The car was built on a heavy steel chassis usually associated with trucks. To reduce weight, Alvis cut a number of holes in the chassis, a solution that Mercedes-Benz chose when faced with the same challenge at the beginning of the decade. The 4-cylinder engine of the previous model was replaced by a 3.5-litre I6 engine with 110 hp (81 kW) and a top speed of almost 160 km/h (160 mph).
