312:. Of these models, the Berliet PR100 proved to be the most successful. Initially considered a temporary solution due to evolving transportation needs, the Berliet PR100's design was later modified to include a third set of double doors, resulting in the Jelcz PR110—a 12-meter bus featuring three sets of doors. Approximately 50% of the parts used in the Jelcz PR110 were imported from France.

Jelcz M11 was equipped with the
Hungarian Csepel 260.88 chassis, which was also used in the Ikarus 260 buses. It was characterized by a high, flat floor. While the chassis was responsible for most of the defects in the Jelcz M11, it allowed for the interchangeability of engine parts between the Jelcz

trucks. According to the agreement, Hungary was to deliver approximately 1,500 complete chassis equipped with engines and gearboxes between 1986 and 1990. The Jelcz M11 (initially named Jelcz M110) was intended as a transitional solution, with production planned to end upon the introduction of the

In 1994, plans were made to adapt city buses to accommodate people with physical disabilities. Expert evaluations determined that the Jelcz M11 buses, along with Ikarus 260 and 280 buses, which were based on the same chassis, were unsuitable for retrofitting with elevators. Additionally, the high

The economic downturn of the 1980s caused a shortage of foreign currency in the Polish People's
Republic, making it difficult to purchase parts needed for manufacturing these vehicles. By early 1984, assembling one bus with imported parts cost $ 2,000

The new Jelcz M11 bus was built on the Csepel 260.88 chassis with the engine. Its body, with minor modifications, was adapted from the Jelcz PR110. The first prototype was completed in 1983. During testing in

Jelcz M11 buses were deployed to city transport operators across Poland, excluding Warsaw. In the 1990s, the M11 was introduced to Warsaw, where it was primarily used by private operators.
