The **Lancia Jota** (from the Greek letter [iota](/source/Iota)) is a series of [truck](/source/Truck) and [bus](/source/Bus) chassis produced by [Lancia](/source/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](/source/Numeral_prefix) added to the name, from **Djota** to the last **Eptajota**. While [axle tracks](/source/Axle_track), [wheelbase](/source/Wheelbase) and equipment gradually grew, the original layout and 4,940 cc [four-cylinder](/source/Inline-four_engine) [petrol engine](/source/Petrol_engine) were retained.

Though most were used as basis for military trucks, goods transport vehicles, or buses, Jota-series [chassis](/source/Chassis) had diverse applications, including special purpose trucks and [artillery tractors](/source/Artillery_tractor).

## Models

### Jota

The Jota was Lancia's first truck, designed for military use. Production for the [Royal Italian Army](/source/Royal_Italian_Army) began in 1915, and continued throughout [World War I](/source/World_War_I), making up two thirds of Lancia's total wartime production of roughly 3,000 vehicles.[1]

The Jota was powered by the *Tipo 61* 4,940 cc [side valve](/source/Side_valve), [monobloc](/source/Monobloc_head) [inline-four](/source/Inline-four_engine), with 70 hp at 2,200 rpm, from the 1912 [Lancia 1Z](/source/Lancia_1Z) military light truck and 1913 [35 HP Theta](/source/Lancia_Theta-35HP) passenger car.[2] Front and rear the Jota used [solid axles](/source/Solid_axle) on semi-elliptic [leaf springs](/source/Leaf_spring); brakes were on the [transmission](/source/Transmission_brake) and on the rear wheels, and the transmission was a 4-speed [gearbox](/source/Manual_transmission) with a multi-plate dry [clutch](/source/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

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 7.77 m2 (83.6 sq ft) and could carry 5.3 [metric tons](/source/Metric_ton) 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 new *Tipo 111* gearbox.[2]

### 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](/source/Lancia_Omicron) in 1927.

### Eptajota

The final 1927 Eptajota was available in *normale* (4.7 m) or *allungato* (extended, 5.0 m) wheelbase.[2]

Eptajota buses were used for the needs of public transport by ATAG in [Rome](/source/Rome),[4] as well as in [Milan](/source/Milan) and other towns and cities in Italy.
