SEGULA Technologies owns a large number of modern exhaust roller dynamometers to offer car manufacturers emission and range tests for passenger cars and light commercial vehicles according to global requirements.

In doing so, we fully support our customers to successfully meet the enormous requirements in the automotive industry in terms of exhaust emissions, fuel consumption and electric range.

Our highly qualified team has many years of experience and expertise on the exhaust roller dynamometer and ensures reproducible, process- and law-oriented execution of the measurements.

Several air-conditioned all-wheel drive test benches (e.g. the altitude climatic test bench for all-wheel drive vehicles, equipped with the latest measurement technology for recording the charge balance) in conjunction with a large and modern workshop enable the laboratory to offer the complete spectrum of testing, engineering, consulting and homologation for both conventional and new drive concepts.

In addition, the test center includes roller dynamometers for vehicle endurance testing.
