The Lancia Epsilon (internal: Type 58) was a two-seater vehicle of the company Lancia, which was produced from 1911 to 1913.
History
The Lancia Epsilon also known as the Lancia 20/30 HP Passo Lungo or Lancia Tipo 58 was based on the previous Lancia Delta, which it replaced. The production expanded once the company took over a factory previously used Fides-Brasier manufacturer. The first new models produced there were the Delta and Didelta, and soon the Epsilon which used a reworked version of the 20 30 engines, mounted in short and long chassis and variety of bodies the chassis were supplied to specialist coach builders. The Chassis numbering is between no. 862 and no. 1799 (the numbering includes, in addition to the Epsilon model, the Eta and Zeta models; according to some sources, the numbering of the Epsilon model would start from the number 862 and end with the number 1212; the examples However, there are 351 built)
The "Type 58 - Epsilon" is similar to the Delta, and for the 1911 model The Gamma Of 1909 and the Delta of 1910 led to the model designated by the next fifth letter of the Greek alphabet, it essentially represented the extended wheelbase version, indispensable for accommodating larger bodywork. About 350 copies were made. Successor was the Lancia Theta.
Apart from a dry multi-plate clutch, there was nothing radical about this Epsilon over previous models. The engine was a Monoblock four-cylinder unit; it was also to be used in the Theta with 4080 cc and an output of 80 hp at 1800 / min. The top speed was 115 km / h. The chassis and suspension were Conventional. The track width was 1330 mm at the front and 1330 mm at the rear and 3227 mm at the wheelbase wire wheels were an option. The top speed was 115 km / h. The track width was 1330 mm at the front and 1330 mm at the rear and 3227 mm at the wheelbase. The chassis and suspension were Conventional type.
Performance:
maximum power 60 HP at 1,800 rpm
maximum speed (with the longest gear ratio) approximately 70 mph/115 km/h
max speed in the various gears: 30 in 1st, 48 in 2nd, 71 in 3rd, approximately 115 in 4th
