EuroBrun ER189

EuroBrun ER189 in the livery of the sponsor Jägermeister from summer 1989.

The EUROBRUN ER189 was the second Formula 1 race car of the Italian team EuroBrun . The car was entered in the 1989 Formula 1 World Championship for seven world championship races. In the following year he appeared, without having experienced any significant changes, for 14 races under the name EuroBrun ER189B . Both versions of the ER189 were unsuccessful racing cars. With a total of 21 attempts in one and a half years, the team only achieved two qualifications; a EuroBrun driver crossed the finish line in one of the races.

background

After an unsuccessful first year, EuroBrun's team boss Walter Brun initially planned to start the 1989 season with a new car, which was to be developed in cooperation with the Brabham team, which was temporarily in his possession . However, since the regulations required each team to design their own car, the desired synergy effects could not be achieved. Therefore, at the end of 1988, Brun had to commission the construction of his own car. Unlike last year, the car was to be developed by British specialists in Great Britain. For this purpose, Brun founded the Brun Technics company in Bicester. The chief engineer there was George Ryton , who began construction of the new EuroBrun in January 1989. Due to financial difficulties of the team, the completion of the car was delayed until the summer of 1989. EuroBrun therefore contested the first races of the year with the transitional model EuroBrun ER188B .

technology

The EuroBrun ER189 was designed by George Ryton and the former Coloni technician Roberto Ori. It was a simple car with no outstanding features. In contrast to its voluminous predecessor, which dates back to 1984, the monocoque was cut very tightly; Claudio Langes , a driver of the 1990 season, regularly had difficulties finding enough space in the narrow car. The lines were flowing. The engine cover now had a working airbox and slowly fell off towards the rear. The side pods were very low. The suspension consisted of double wishbones with push rods. The suspension proved problematic; therefore, the team replaced it in late summer 1989 with the old suspension from the ER188B.

As in the ER188B, a Judd eight-cylinder type CV served as the drive , the output of which with around 600 hp was almost on the level of the Cosworth DFR engine.

In 1989 there was only one ER189B vehicle; The replacement car at this time was the ER188B.

Races

The ER189 was used in seven world championship races in 1989, starting with the German Grand Prix . It stood out for its orange paintwork, which was due to the sponsor Jägermeister . Its driver was initially Gregor Foitek ; later the Swiss was replaced by Oscar Larrauri . Both Foitek and Larrauri failed regularly in the pre-qualification in 1989.

When the ER189 in its original form turned out to be unsuitable for racing after two Grand Prix, Brun temporarily withdrew the car to allow modifications, which included installing the rear axle of the old car. The team therefore reported the ER188B again at the Belgian Grand Prix.

For the 1990 season, the ER189 should initially only serve as a transitional model. Walter Brun intended, with the help of sponsorship money from the United Arab Emirates, to construct a completely new car called the ER190, which was to exclusively use a twelve-cylinder engine developed by Neotech in Austria . However, the project failed in the spring of 1990 when the hoped-for sponsorship funds failed to materialize.

Technology and special features

The 1989 copy of the ER189B was used in the 1990 season. In addition, in the winter of 1989/90, the team built a second car that was conceptually the same as the first car. Also in 1990 the cars were powered by the Judd CV engine. The preparation of the engines, which are now in their third season, took place in Switzerland.

Only minor modifications were made during the spring. The only major change was the conversion of one of the two cars to a single front shock absorber (monoshock), which was carried out on the occasion of the French Grand Prix . With this development, the team followed the trend set by the successful Tyrrell 019 . The monoshock damper did not lead to any improvement in driving behavior, however, so that the team soon turned its main focus back to the second car, which had conventional double shock absorbers. In the last races of the year, the monoshock ER189B was mostly left to Claudio Langes, the team's less successful driver.

There are uncertainties regarding the nomenclature of the car. Some sources refer to all cars used in 1990 as EuroBrun ER189B, while others only use the name ER189B from the third race of the season and do without the suffix “B” for the first two races.

Races

The EuroBrun ER189B was used in two copies in 14 races in 1990. The drivers were Roberto Moreno and Claudio Langes. The latter kept the team alive through his sponsorship money, but was overshadowed by Moreno, on whose commitment the team concentrated.

Langes failed the pre-qualification fourteen times in a row, Moreno was able to qualify twice for participation in the race. The first race of the year, the US Grand Prix in Phoenix, was outstanding : Here Moreno drove the fastest time in the pre-qualification by a clear margin and was second fastest in the peloton in Saturday practice in the rain. As a result, he reached position 16 on the grid, the best in the team's history. Moreno finished the race in 13th place. At the Grand Prix of San Marino Moreno was able to qualify again for starting place 24; in the race, however, he retired on the first lap due to engine failure. In the remaining races Moreno failed to qualify. The team gradually fell away. In view of the lack of test drives, no competitive set-up could be developed; the drivers repeatedly described the driving behavior of the car as a "disaster".

After the last European race of the year, EuroBrun ceased racing.
