Autonomously acting vehicles, connected cars, alternative drive systems, reduction of emissions in conventional drive systems, telematics that interact with state-of-the-art mobile telephones, but also mobility concepts such as carsharing all place great demands today on the vehicles of tomorrow. Together with manufacturers and developers, straesser is actively helping to shape the mobility of the future. The revolutions in the sector toward digitally networked, quiet, and emission-free vehicles are larger than ever. Such challenges can be met only with excellent employees who are always up to date. That is why we constantly train our experts and our entire company, whether in driving safety, in working safely with high-voltage systems, in planning test procedures, or in quality management and project management.
Our services in detail
Whether two wheels or ten, straesser tests in all vehicle classes for its customers. From motorcycles to tractor vehicle with semitrailer, from left-hand-drive vehicles to right-hand-drive vehicles and even centre-drive vehicles — our employees test-drive the vehicles professionally and responsibly.
Testing services during road tests
Vehicles are complex machines with a number of various assemblies and subassemblies, systems, and individual components that ideally all work together smoothly. We want to make a significant contribution to assisting our customers achieve this goal by testing vehicles during the development stage as well as testing pre-series and production-ready vehicles.

Measurement technology for vehicle road tests
Within the ATESTEO corporate group, straesser has access to high-quality measurement equipment from the specialists for drivetrain testing.
Vehicle testing on the dynamometer
Besides tests and endurance runs on roads and test tracks, vehicles can also be tested on a dynamometer (roller test bench). Vehicle masses of up to 3,500 kg can be simulated here. Fuel consumption, functional tests, and service life (endurance, durability) tests are conducted on passenger cars and commercial vehicles on the dynamometer.
Vehicle testing on the vehicle acoustic chassis dynamometer
The ATESTEO vehicle acoustic roller test bench is used for measuring vehicle noises. Motorcycles, passenger cars, and commercial vehicles can be tested on this dynamometer with respect to noise emissions from the transmission and drivetrain. The test bench is suitable in accordance with DIN 45635 for sound level measurements of accuracy class 1.
Data on the ATESTEO acoustics dynamometer:
| Acoustic test bench | All-purpose test bench | |
|---|---|---|
| One-axle single-roller diameter (Ø) | 1,909 m | 1,219 m |
| Direct current (DC) machine | 300 KW | 150 KW |
| Tensile force/Overload | 8 kN / 12 kN | 5.4 kN / 6.12 kN |
| Vehicle mass that can be simulated | 500 – 3.500 kg | 450 – 3.000 kg |
| Vmax | 250 km/h | 200 km/h |
