TheLancia Jota (from the Greek letteriota) is a series oftruck andbus chassis produced byLancia between 1915 and 1935. The original 1915 Jota was the first true Lancia truck; throughout the following two decades it was made in a number of different series and variants, each identified by a progressive Greeknumeral prefix added to the name, fromDjota to the lastEptajota. Whileaxle tracks,wheelbase and equipment gradually grew, the original layout and 4,940 ccfour-cylinderpetrol engine were retained.

Though most were used as basis for military trucks, goods transport vehicles, or buses, Jota-serieschassis had diverse applications, including special purpose trucks andartillery tractors.

The Jota was Lancia's first truck, designed for military use. Production for theRoyal Italian Army began in 1915, and continued throughoutWorld War I, making up two thirds of Lancia's total wartime production of roughly 3,000 vehicles.^[1]

The Jota was powered by theTipo 61 4,940 ccside valve,monoblocinline-four, with 70 hp at 2,200 rpm, from the 1912Lancia 1Z military light truck and 191335 HP Theta passenger car.^[2]Front and rear the Jota usedsolid axles on semi-ellipticleaf springs; brakes were on thetransmission and on the rear wheels, and the transmission was a 4-speedgearbox with a multi-plate dryclutch.

A short-wheelbase version of the Jota, it was produced in comparatively small numbers and almost exclusively for the military during the war.

The postwar 1921 Triota adopted a modifiedTipo 64 engine as well as a differentTipo 107 gearbox, in place of the previoustipo 61 andtipo 106.

Also launched in 1921, the Tetrajota had widened front and rear axles, a design carried over to all subsequent models.

In 1924 Lancia replaced Tetrajota with the Pentajota. Available innormale (4.3 m) orcorto (short, 3.8 m) wheelbase, with almost 2,200 made it was the most successful model in the series.A Pentajota normale had a loading area of 7.77 m² (83.6 sq ft) and could carry 5.3 metric tons of goods,^[3] more than twice as much as the first Jota. It introduced to the series four wheel brakes (front pedal-actuated, rear hand brake) and a newTipo 111 gearbox.^[2]

The Esajota was a very long wheelbase bus chassis. It was built in 13 examples during 1926, and was replaced by the dedicatedLancia Omicron in 1927.

The final 1927 Eptajota was available innormale (4.7 m) orallungato (extended, 5.0 m) wheelbase.^[2]

Eptajota buses were used for the needs of public transport by ATAG inRome,^[4] as well as inMilan and other towns and cities in Italy.
