Lancia Epsilon

For the similarly named car, see Lancia Ypsilon.

The Lancia 20/30 HP (Tipo 58), later known as Lancia Epsilon,^[a] is a passenger car produced by Italian car manufacturer Lancia between 1911 and 1912. The car was quite similar to the previous 20/30 HP Delta model.^[1] In total 357 were made.^[1]

Models

Three wheelbase lengths were offered, resulting in a choice of five different models—depending on the desired body style:

• Type A: normal wheelbase, for phaetons, landaulets, limousines and coupés
• Type B: long wheelbase, for phaetons, landaulets and limousines
• Type C: short wheelbase Corsa, for competition two- or three-seaters
• Type D: normal wheelbase, for torpedoes
• Type E: long wheelbase, for torpedoes and cabriolets

Specifications

The Epsilon was powered by a Tipo 58 side valve monobloc inline-four, displacing 4,080 cc, which produced 60 hp at 1,500 rpm.^[1] Top speed was 115 km/h (71 mph).^[1]

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

Notes

1. 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.
