Alvis Car and Engineering Company Ltd was a British manufacturing company in Coventry from 1920 to 1967. In addition to automobiles designed for the civilian market, the company also produced racing cars, aircraft engines, armored cars and other armored fighting vehicles.

Alvis produced 20,374 cars between 1920 – 1967. 4,703 are known to survive (23%).

The Speed 25 has a 3.5 liter 6-cylinder seven main bearing engine, three S.U. carburetors producing 108 hp, all-synchro gearbox, independent front suspension and servo-assisted brakes.

Alvis did not make any of the bodies for any of their vehicles. The cars were supplied in chassis form and coachbuilding firms such as Cross & Ellis, Charlesworth, Vanden Plas, Lancefield, Offord and others would fit open, touring or saloon car bodies.

391 Speed 25s were made from 1936-1940. Of the 391, ten had Vanden Plas coach-built bodies:1

convertible, 1 tourer, and 8 saloons (sedans). Of the 8 saloons, 3 were in this 2-door style. Body

numbers 3506, 3507, 3508. 3506 is a re-bodied 2 seat special in Germany. 3508 was last heard of in

August 1963, advertised as ‘breaking for spares’ and possibly might still be lurking in a barn!

3507 is the sole (known) Alvis Speed 25 survivor of this body style.

153 original and 51 specials of the 391 Speed 25s are known to survive (52%)

This Speed 25 has never been restored and is designated by the Antique Automobile Club of America

(AACA) as ‘Historical Preservation of Original Features’ (HPOF).
