Company history

From carriages to buses.

We have been writing the history of public transport

The first bus of Josef Sodomka left the bodywork factory as early as in 1928.

The history of IVECO BUS in the Czech Republic goes back to 1895 when Josef Sodomka founded his wheelwright’s workshop in Vysoké Mýto. For over two decades he had manufactured mostly carriages and automobile bodies. Up to 1928, when his bodywork factory gave birth to the first 14-seat bus on a Škoda 125 chassis.

The key moment in the company history was 1948 when the company was transformed into the KAROSA state enterprise strictly specialized in bus manufacture. As early as then, KAROSA could be proud of a range of unique technological solutions and successful bus models and it ranked among the most renowned Czech enterprises. The supranational success of KAROSA is inseparably bound to its connection with the Renault and subsequently Irisbus brands in the 90s.

In 2003, IVECO became a complete owner of Irisbus and the company entered its new era which resulted in the change of the Irisbus brand to IVECO BUS in 2013. Thanks to our experience and the strong background of the supranational CNH Industrial group, our buses sell successfully all over the world today.

The manufacture on the Praga NDO chassis

In 1938, buses on the Praga NDO chassis started to be manufactured in city bus and tourist coach modifications. First vehicles were built for public transport operators in Brno and Olomouc, while during the war the main customer was the Czech-Moravian Railways (ČMD). The mixed wood-metal construction, used at the beginning of the manufacture, was later replaced with the all-metal construction. Another significant contract was a series of fifty buses designed for participants in the 11th Sokol Gathering Festival which took place in Prague in 1948. The vehicles were equipped with two wide four-wing pneumatic doors and the Praga-Wilson automatic 5-speed transmission. 195 Praga NDO buses in total were manufactured in Vysoké Mýto.

As a follow-up to this contract, the Czechoslovak Railways (ČSD) ordered another series of these vehicles for the same customer at the turn of 1945 and 1946. About twenty buses in total were thus supplied to Slovakia.

1942
milestone

The manufacture on the Škoda 256 B chassis

Between 1946 and 1947, the body workshop of Josef Sodomka manufactured buses on the Škoda 256 B chassis. These small vehicles were made in several variations, with lengthwise or transverse orientation of seats for no more than 25 passengers. Their main purchaser was the Czechoslovak Railways (ČSD), but there were also other customers among other companies and organizations throughout the country, e.g. the Headquarters of the National Security Forces in Bratislava purchased 38 of them. Four buses were manufactured for the Czechoslovak Airlines. At least 150 of these vehicles were manufactured in total.

1946
milestone

The manufacture on the Škoda 706 RO chassis

In 1947, the company launched the manufacture of buses on the Škoda 706 RO chassis, which went on even after the founding of the Karosa state enterprise. They became the key product of the factory in Vysoké Mýto, and during ten years 2,916 of these buses were manufactured in versions for city, intercity and coach transport. Thanks to their low demands and reliability they were very popular both in Czechoslovakia and abroad where a significant part of production was exported.

The manufacture of the Karosa T 500 HB mountain buses

From 1954 the state enterprise manufactured the Karosa T 500 HB mountain buses, medium-size vehicles for 60 passengers. The aim of this project, realized in cooperation with Tatra Kopřivnice, was to provide transport in demanding mountain conditions. The equipment of these three-axle buses with a semi-self-supporting body included the Tatra air-cooled engines placed in the rear part of the body, which was a globally unique solution at that time. 524 of these vehicles in total were manufactured until 1957.

1954
milestone

The new luxurious Škoda 706 RTO coach

At the Exhibition of Czechoslovak Engineering in Brno in 1956, Karosa presented a new luxury coach Škoda 706 RTO built on a modernized chassis from the LIAZ Jablonec state enterprise. This vehicle with an exceptionally successful design, the typical features of which included round shapes of the body and large glass surfaces on the sides and the roof, won the admiration both of specialists and non-professional public. The series production of these buses went on until 1971. The Brussels World Fair EXPO 58 witnessed a premiere of a luxurious RTO coach with an exceptional interior equipment with a buffet, changing room, radio and TV set. The RTO buses were very popular and thanks to their qualities, which included the elegant look, reliability and low fuel consumption, they became a legend. They were also used for special purposes, e.g. as service vehicles, mobile groceries, service vehicles, postal vans, mobile libraries and X-ray vans, or as surgical buses. Progressive prototypes based on the RTO range included also an articulated bus. In total, Karosa produced 14,969 buses of this type, in versions for city, intercity line a and coach transport, and a substantial part of the production was exported to many countries in Europe, Asia, Africa and South America.

The manufacture of the Š 11 range buses

Karosa had been gradually developing the manufacture of buses of the Š 11 range from 1965. The city version represented the basic type from which the intercity line and coach versions were derived. The vehicles were equipped with the horizontal Liaz ML 634 engine situated, together with the gearbox, under the floor between axles. The drivability of the bus was significantly improved by air suspension, unique with respect to global trends at that time, and also the used unique technology was “ahead” of the world standards – the whole vehicle was composed of six main panels manufactured separately, including the surface treatment and almost the complete equipment. The engine and other driving-gears were fixed to the body grid, to which were then bolted other completed panels, one by one, on the production line. This simple and revolutionary method of production meant huge progress for bus production at Karosa. Several other variations were later created as well, e.g. the Evropabus long-distance coach with a “rotel” sleeper trailer, various service vehicles, mobile libraries and also the luxurious ŠD 11 Superflux coach which won a huge recognition and was awarded with a Silver Cup at the Nice exhibition in 1969. At the same time, also 15-vehicle testing series of articulated bus were developed and manufactured. In total, 26,669 buses of the Š 11 range were manufactured, while almost 20 % of this production was exported.

A novelty: A 7 m long bus built on an Avia-Saviem chassis

A short, 7 m long bus built on an Avia-Saviem chassis, both in a line and long-distance version, became a novelty of 1969. A small series of 13 vehicles were manufactured in 1972, modified for the Czechoslovak Radio in Prague and Bratislava. Karosa manufactured thirteen of them in total.

1969
milestone

The new 700 range

The successful and popular “ŠMs” were replaced with the new 700 range the manufacture of which was also based on the panel structure system. However, the key innovation was the engine and gearbox shifted behind the rear axle. The more modern construction and improved technology of the product also helped to raise the volume of the production up to fourteen vehicles a day between 1981 and 1990. The basic model of this range was the Karosa C 734 intercity line bus equipped with the Liaz ML 636 turbocharged engine with a Praga mechanical transmission. This type was then followed by city buses with an automatic transmission, suburban buses with a mechanical transmission, as well as intercity and long-distance coaches. The concept of the 700 range enabled to manufacture also articulated buses on the same assembly line. From the beginning of the series manufacture in 1981 to its end in 1999, the production plant produced 37,166 vehicles of this range in total.

In 1992, Karosa offered its customers a novelty in the form of the luxurious LC 757 HD 12 long-distance coach which won the Golden Medal at the Autotec exhibition in Prague. The vehicle with a raised floor met the most demanding requirements on long-distance passenger transport, and, apart from air-conditioning and other important safety features, it could boast of luxurious equipment, e.g. a kitchenette, refrigerator, WC and a video system. The vehicle was driven by a vertical Cummins engine, situated behind the rear axle, later replaced with a Renault. The 12 m long coach took in 41–47 seated passengers, depending on its equipment quality level, and its maximum speed was 100 km/h. Until the end of the millennium the number of these vehicles manufactured in Karosa reached 98.

The KAROSA joint stock company, Vysoké Mýto

The privatization brought a significant change: on 1st July 1993, the Karosa joint stock company (1,706 employees) was established, specialized in the bus manufacture. The remaining production plants of the former Karosa state enterprise become independent privatized enterprises. Negotiations with the French company Renault V.I. resulted on 2nd November 1993 in the foundation of a joint undertaking, Renault V.I. holding a share of 34 % and the European Bank for Reconstruction and Development holding a share of 17 %.

New buses of the 900 range

In this year, Karosa manufactures and introduces to the market the first bus of the 900 range, the overall score of which was 12,944 manufactured vehicles in the end. This bus is the first one to carry the Renault logo.

After the privatization of the enterprise in 1993, Karosa commenced the development of the new 900 product range the overall score of which was 12,944 manufactured vehicles in the end. This bus was the first one to carry the Renault logo. These vehicles were modernized and converted buses of the previous 700 range whose reconstruction focused especially on the innovation of the body design, more comfort both for driver and passengers and increased quality and lifetime of the vehicles. Another significant benefit was their ecological operation. The first B 931 vehicles sold as early as at the end of 1995, while all the remaining types, i.e. line buses, long-distance and tourist coaches, were being introduced to the market gradually between 1996 and 1997. They were equipped with the Liaz ML 636 or Renault 6-cylinder engines meeting the Euro II emission standards and imported VOITH or ZF gearboxes.

Irisbus holding

A joint undertaking of the Italian company Iveco and the French company Renault V.I. was established on 1st December 1999 to coordinate the purchase of strategic components, industrial politics and development. This new Irisbus Holding S.L. group acquired a 94% share in Karosa. By unifying their activities in the field of bus and coach manufacture, the Iveco and Renault companies created an undertaking of international dimensions – the second largest manufacturer in Europe and a prominent global company. In this company, Renault V.I. owned a 50% share and the other 50% share was owned by Iveco.

The introduction of the new 950 range with Iveco Euro III engines

The next innovation of the 900 range buses brought their prolongation to 12 metres. In 2002, the new 950 range was introduced to the Karosa assembly line, with Iveco Euro III engines. Nevertheless, the modernization involved also a significant part of the chassis and body, therefore the innovation had an impact also on other aggregates, e.g. the intercity and long-distance buses were equipped with disc brakes, which contributed to their safe operation. From July 2001, all types of vehicles had been receiving the cataphoretic (anti-corrosion) immersion treatment. The manufacture of the successful 900 range ceased in 2006, with the total score of 13,071 manufactured buses.
