The Adler 2.5 liter is a car that the Adlerwerke brought out in 1937 as the "Type 10". It was intended as the successor to the Diplomat model . The streamlined body was the work of chief designer Karl Jenschke (1899–1969), who was chief engineer at Steyr-Daimler-Puch AG until November 1935 . It was there that he last designed the type 50 ("Steyr-Baby") small car , which the Adler 2.5 was very similar to. Because of the streamlined shape and the large number of new motorways that were completed around the same time , the car was popularly known as the motorway eagle or the eagle motorway car.
The four-door sedans with sunroof karossierte Ambi Budd , the two- and four-seat convertibles were from Karmann .
In 1938 a two-door sports sedan appeared as the Adler 2.5 liter Sport . Its engine was more highly compressed (1: 7.25 instead of 1: 6.25) and had three flat-flow register carburettors instead of the two Solex falling-flow carburetors. This increased the engine output to 80 hp (59 kW). The elegant body with covered rear wheels was supplied by Buhne in Berlin and glasses in Dresden.
engine and gears
The Adler 2.5 liter had a longitudinally installed water-cooled six - cylinder four-stroke in-line engine with a displacement of 2494 cm³, four-bearing crankshaft and pressure circulation lubrication . The stationary valves were controlled by a side camshaft driven by spur gears . The radiator, engine and transmission were well ahead. The power was transmitted to the rear wheels via a cardan shaft .
The four-speed transmission was synchronized in gears two to four. It was switched with a handle on the dashboard (so-called revolver circuit ).
Frame and chassis
The load-bearing element of the car was a box frame welded to a floor platform, the side members of which were arched around the floor of the vehicle in order to achieve a spacious interior ("fish belly frame"). The front wheels were suspended from wishbones and quarter elliptical springs, the rear wheels from a pendulum axle with tension struts and transverse leaf springs. The differential was bolted to the frame. All four wheels had hydraulic shock absorbers and hydraulically operated drum brakes. The steering was a ZF - Ross steering .
body
The four-door all-steel body with hatchback, welded to the frame and with a drag coefficient of 0.36, was considered very aerodynamic in its time. In the basic configuration it had four doors that were hinged on the B-pillar, and a large steel sliding roof that reached almost the entire width of the roof and from the windshield to over the second third of the rear doors. In 1939, however, this large sunroof was reduced in size to make it easier to move. Right from the start, the headlights, which were placed close together next to the radiator grille, proved to be of little use and were therefore supplemented by so-called "broad radiators" on the fenders, of which only one was permitted from 1938.
The bodywork improvements from 1939 included the trunk, which was accessible from the outside, with a flap that reached under the rear window instead of the small opening for the spare wheel. In addition, the rear wheel cutouts received covers. In addition, the dashboard with a speedometer, fuel gauge, temperature and oil pressure display and time clock has been made clearer.
Production period
The Adler 2.5 liter was presented in spring 1937 at the 27th International Automobile and Motorcycle Exhibition (IAMA) in Berlin. The first vehicles were not delivered until November, however, at a price of 5750 Reichsmarks. By 1940 a total of 5295 motorway eagles had been built . A 4-door sedan from 1938 is in the Aspang Automobile Museum in Aspang-Markt in Lower Austria .
