The Lancia 20 HP (Tipo 55), later renamed Lancia Gamma,^{[lower-alpha 1]} is a passenger car produced by Italian car manufacturer Lancia during 1910. It was derived from previous Beta model, now equipped with a bigger engine. In total 258 units were built.^[1] In 1911 the type was superseded by the larger-engined and more powerful Lancia 20-30 HP Delta.

The Delta was built with two wheelbases, normal and short. The latter was destined for competition-oriented Corsa models, to be bodied as open two- or three-seaters.

Specifications

The engine was a Tipo 55 side valve inline-four, with cast-iron monobloc engine. Bore and stroke measured 100 mm × 110 mm (3.9 in × 4.3 in), for a total displacement of 3460 cc.^[1] The engine produced 40 hp at 1500 rpm, giving the car a top speed of 110 kilometres per hour (68 mph)—the same as the six-cylinder Dialfa of two years earlier.^[1]

The transmission was a 4-speed gearbox with a multi-plate wet clutch. The separate body was built on a conventional ladder frame; fore and aft there were solid axles, on semi-elliptic springs at the front and three-quarter elliptic springs at the rear. Braking was by drums on the transmission and on the rear wheels.

Notes

↑ All early Lancia models were named after their tax horsepower rating, as was common practice; when in 1919 Lancia began naming its passenger cars with Greek alphabet letters, all earlier models were posthumously renamed in order of appearance—from the 1907 Alfa to the 1913 Theta.
