History of the 1933 - 1935 Alvis Speed 20

Model History Alvis Speed 20 1931 to 1936

The Alvis Speed 20 is a saloon, drophead and bare chassis produced between 1931 and 1936 in four series: SA, SB, SC and SD. Described in advertising as 'An entirely new sports car with a genuine 100mph chassis' the car actually topped out at closer to 90mph once the body had been fitted, typically by Vanden Plas, Charlesworth or Cross and Ellis. Nevertheless, it was an impressive sports car in any body shape and sales, although small, tended to be to rich men who considered themselves serious drivers.

The model was developed almost annually throughout its life. Between launch and 1935, the car was powered by a straight-six 2511cc OHV engine, then being enlarged to 2762cc for the SC and SD models. In its final year, the model gained a 3571cc engine, eventually being redesignated the Speed 25. Early SA models tend to be considered the most pleasing to drive with front beam axles, but SBs gained a four-speed synchro gearbox, independent rear suspension, adjustable rear dampers and larger Lucas P100 headlamps, giving it a purposeful, sporting look. For the SC, the newer engine was complimented by improved steering, a stiffer chassis and better front damping. The SD became wider and gained a bigger fuel tank.

Today, as with many pre-war coachbuilt cars, values vary a great deal. Rare, one-off designs tend to sell for the highest values, with drophead four-seat 'Tourer' bodies next, especially those by Vanden Plas. Saloon values tend to be lower, although the elegant and very rare 'flat back' Vanden Plas saloon is considered to be very beautiful and priced accordingly. Charlesworth dropheads and saloons tend to achieve the lowest values.
