The '''Lancia Jota''' (from the Greek letter [[iota]]) is a series of [[truck]] and [[bus]] chassis produced by [[Lancia]] 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 Greek [[numeral prefix]] added to the name, from '''Djota''' to the last '''Eptajota'''. While [[axle track]]s, [[wheelbase]] and equipment gradually grew, the original layout and 4,940 cc [[Inline-four engine|four-cylinder]] [[petrol engine]] were retained.
Though most were used as basis for military trucks, goods transport vehicles, or buses, Jota-series [[chassis]] had diverse applications, including special purpose trucks and [[artillery tractor]]s.
==Models== ===Jota=== The Jota was Lancia's first truck, designed for military use. Production for the [[Royal Italian Army]] began in 1915, and continued throughout [[World War I]], making up two thirds of Lancia's total wartime production of roughly 3,000 vehicles.{{sfn|Amatori|1992|pages=31–33}}
The Jota was powered by the ''Tipo 61'' 4,940 cc [[side valve]], [[Monobloc head|monobloc]] [[Inline-four engine|inline-four]], with 70 hp at 2,200 rpm, from the 1912 [[Lancia 1Z]] military light truck and 1913 [[Lancia Theta-35HP|35 HP Theta]] passenger car.{{sfn|Amatori|1992|pages=403–405}} Front and rear the Jota used [[solid axle]]s on semi-elliptic [[leaf spring]]s; brakes were on the [[Transmission brake|transmission]] and on the rear wheels, and the transmission was a 4-speed [[Manual transmission|gearbox]] with a multi-plate dry [[clutch]].
===Djota=== A short-wheelbase version of the Jota, it was produced in comparatively small numbers and almost exclusively for the military during the war.
===Triota=== The postwar 1921 Triota adopted a modified ''Tipo 64'' engine as well as a different ''Tipo 107'' gearbox, in place of the previous ''tipo'' 61 and ''tipo'' 106.
===Tetrajota=== Also launched in 1921, the Tetrajota had widened front and rear axles, a design carried over to all subsequent models.
===Pentajota=== [[File:Lancia Pentajota (1924-1929).jpg|thumb|Lancia Pentajota (1924-1929)]] In 1924 Lancia replaced Tetrajota with the Pentajota. Available in ''normale'' (4.3 m) or ''corto'' (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 {{convert|7.77|m2|abbr=on}} and could carry 5.3 [[metric ton]]s of goods,<ref>{{cite web |url=http://www.lancia.com/com/en/history/model-history/ |title=Historic models |publisher=Lancia Automobiles S.p.A. |access-date=29 April 2015 |archive-url=https://web.archive.org/web/20150422065736/http://www.lancia.com/com/en/history/model-history |archive-date=22 April 2015 |url-status=dead }}</ref> 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 new ''Tipo 111'' gearbox.{{sfn|Amatori|1992|pages=403–405}}
===Esajota=== The Esajota was a very long wheelbase bus chassis. It was built in 13 examples during 1926, and was replaced by the dedicated [[Lancia Omicron]] in 1927.
===Eptajota=== The final 1927 Eptajota was available in ''normale'' (4.7 m) or ''allungato'' (extended, 5.0 m) wheelbase.{{sfn|Amatori|1992|pages=403–405}}
Eptajota buses were used for the needs of public transport by ATAG in [[Rome]],<ref>{{cite web |url=http://www.tramroma.com/autobusroma/rete_urb/autobus/rotabili/autrot_03.htm |title=I Lancia Eptajota |work=Rotabili della rete romana di autobus [Rolling stock of the Roman bus system] |publisher=Autobusroma |last=Di Pietrantonio |first=Mauro |language=IT}}</ref> as well as in [[Milan]] and other towns and cities in Italy.
