1935 Alvis Speed 20

Introduced at the 1934 London Motor Show, the Speed 20 SC was among a new breed of Alvis cars that combined high performance (a long-recognized marque virtue) with luxury and refinement. Based around a sturdy cruciform - braced ladder - framed chassis, the new model came equipped with sizable fourteen-inch drum brakes and 'jelly mould' wire wheels. The car boasted such technological novelties as independent transverse leaf front suspension. Powered by a smooth but free revving 2762cc OHV straight-six engine featuring dual magneto/coil ignition, triple SU carburetors, and an aluminum crankcase, it was reputedly capable of 89 mph. Only 29 SC Vanden Plas sport touring were made.

The first vehicles to bear the Alvis name, founded by Thomas George John and G. P. de Freville, appeared in 1920. Production of the Alvis vehicles would last for 47 years ending in 1967. The vehicles quickly built a reputation for performance and for their durability, and quality craftsmanship. The company, during its lifespan, would also be involved in the production of aero-engines and military vehicles.

The Speed 20 was introduced in 1932 and were available in various configuration. Production would continue until 1936. The 4 door touring version was the standard configuration with Cross & Ellis handling these coachwork orders. The 4 door saloon was courtesy of Charlesworth. The two-door tourer, two-door sports saloon, and drophead coupe versions were created by Vanden Plas.

When introduced the engine offered was a six-cylinder unit with pushrod overhead valves, three SU carburetors, and about 86 horsepower. Their engines were referred to as 'Silver Eagles'. The suspension was comprised of semi-elliptical springs in the front and rear. 14-inch drum brakes provided the stopping power. Specifications varied and were continually improved. In 1933 the Crested Eagle was introduced which used an independent suspension with a transverse leaf spring and wishbone setup.

In 1936 production of the Speed 20 ceased with around 750 examples being produced.
