  • 4.1 Dimensions
  • 4.2 Specifications



The not drivable prototype was in September 1957 at the IAA in Frankfurt am Main. The car was equipped with a two -cylinder boxer engine and front wheel drive.

Subsequently, however, it turned out that he had got far too top-heavy, because the engine was far ahead of the front axle. Restore the drive block would have a complete redesign of the body does what neither time nor money were available. Therefore, the designers opted for a conventional rear-wheel drive. The system, designed for front-wheel drive four-speed transmission could also not be changed, so that a somewhat unusual shift pattern revealed: The 2nd and 4th gear were in front, the 1st and 3rd rear. For series production, yet some was also stylistically changed and relocated the spare tire from the trunk over the engine.

Goggomobil T 600

On 12 June 1958, the series production of the new four-seat sedan with two doors began. Panoramic windshield, small rear fins and the two-tone paint and reflected contemporary fashion that came from the USA to Europe. The keyhole- shaped rear light clusters were reminiscent of the Opel Kapitän this time. Remarkably for the time was the self-supporting all-steel body with (from 1959), reinforced by box-shaped longitudinal girders bottom part. The front wheels were individually suspended from the lower lateral and upper trailing arms with coil springs; rear had the car - as still widespread at that time - a rigid axle with leaf springs.

The boxer engine with a displacement of 584 cc, developed 20 hp (15 kW ) at 5000 rpm. Thus, a maximum speed of 98 km / h was reached. The approximately 640-650 kg car accelerated in 61 seconds from 0 to 100 km / h; Fuel consumption: 5.3 l/100 km regular gasoline.

Goggomobil T 700

As of August 1958, the first version has been given a more powerful variant to the side. Your engine had 688 cc and made 30 hp (22 kW). The top speed was 110 km / h acceleration 40 seconds (0 - 100 km / h). Consumption increased to 5.8 l/100 km.

Glass Isar ( sedan and wagon )

To detach from the Goggomobil microcar, which technically unchanged cars received in November 1959, the name Isar Isar T 600 and T 700 At the same time also appeared three-door station wagon variants, the Isar Isar K 600 and K 700 were called.

Big facelift

In August 1960 published by all four variants revised models. The cars were grown in length by 25 mm ( by essays from plate for the new tail lights ) and had desired front and rear chrome bumper bar - according to the new rules for the United States. Instead of the rear lights in keyhole shape, there were now elongated specimens of about twice the size. Adapted to the new rear lights had the Isar rear bumper now curved corners, large trunk lid handle disappeared and license plate light wandered into the middle part of the rear bumper. The roof was raised slightly in the rear area, leaving space for a much larger rear window was created. In the last -built models, the dashboard was covered with black imitation leather, also the steering wheel and the front seats have been installed from the larger model 04.

The weaker -powered variants had only 19 hp ( 14 kW ), but reached 105 km / h top speed.

In this form, the cars were manufactured until August 1965.

Technical Problems

The first versions of the "Great Goggomobil " suffering from bad childhood diseases: The die-cast aluminum housing of the motors were deformed at high operating temperatures. This defect in the fuel consumption could rise up to 12 l/100 km. The bodies verwanden so strong that cracks originated and in the worst case, the panoramic windscreen fell out of their frame on bad roads. The complaints cost the Hans Glas GmbH a lot of money and damaged the reputation of the company.
