ATESTEO acquires straesser, a leading vehicle testing service provider

3i Group plc (“3i”) today announces that ATESTEO, an international drivetrain testing specialist in which 3i invested in 2013, has acquired a majority stake in straesser, a leading player in road testing and vehicle test driving services.

The acquisition expands ATESTEO’s offering in the field of road trials, opening up significant growth potential.

Ulf von Haacke, Partner & Head of Industrial at 3i, commented:

“3i is pleased to support ATESTEO in this second add-on this year, following the acquisition of a drivetrain testing site in Munich in January. Both straesser and ATESTEO already have leading market positions and are growing strongly in their respective markets. They are highly complementary and together will be well positioned to lead the way in testing the quality of increasingly electrified and autonomous automotive technology.”

Wolfgang Schmitz, Chairman of the Management Board of ATESTEO, added:

“We continue to develop our portfolio of services for the benefit of our customers. By acquiring a majority stake in straesser, we are expanding our offering into an important growth market and extending our range of services to pre-series and series production tests, vehicle endurance runs, vehicle testing, and workshop activities for test vehicles. Together, we are a one-stop shop offering a comprehensive testing portfolio for the industry and we look forward to working with our new colleagues at straesser both in Germany and across Europe”.

straesser is headquartered in Kernen, near Stuttgart in Germany, and has over 280 employees. Its customer base comprises a wide range of well-known automotive manufacturers, suppliers and development and engineering service providers. Testing is carried out on proving and testing grounds as well as on public roads around the world.

straesser will continue to operate under its own name, but within the ATESTEO Group. Rolf Strässer will remain Managing Partner.
