The vehicle components are cooled by a ram air fan (front left) with an airflow of up to 180 km/h. This makes highly dynamic driving manoeuvres possible.

The total of ten vehicle test rigs are used to perform such work as the fine tuning of engine and transmission, with comfort, dynamics and agility being matched to each other.
16C880_003
Especially the development of alternative drive systems has increased the demand for testing on chassis dynamometers. The Powertrain Integration Centre (AIZ) offers reproducible test conditions.
16C880_007
The total of ten vehicle test rigs are used to perform such work as the fine tuning of engine and transmission, this involving extensive wiring-up of the vehicles in advance of the tests.

The test rigs are highly automated: the vehicles are electronically controlled, accelerated and decelerated as if by magic or shift through the gears.
16C880_056
As the engineers and technicians are not in the car, but outside at the control console, they are able to simultaneously evaluate the measurements using newly developed tools.
16C880_063
The vehicles require extensive preparation for operation on the test rigs, this being facilitated by, among other things, the automatic parking storage system and the high-bay tyre warehouse.
16C880_069
The Powertrain Integration Centre (AIZ) includes a workshop for preparing the test vehicles as well as 16 cold chamber places for pre-cooling the vehicles prior to testing in the climatic chamber.

16C880_119
On this state-of-the-art vehicle powertrain test rig, the vehicle does not run on a conventional roller, but is directly connected to a high-power asynchronous machine by means of a special wheel hub on each wheel with the use of a high-precision torque-measuring system.
