MAN Engines: We are perfectionists!

International Engine Competence Centre Nuremberg

Our heart beats for engines: At MAN Truck & Bus SE’s international engine competence centre, we are concerned exclusively with ensuring that engines run as efficiently and durably as possible.

The entire MAN Truck & Bus SE engine know-how concentrated at one location: Around 4,000 experienced employees dedicate all their energy to the development, design and production of MAN engines, right through to sales and after-sales. On a plant area equivalent to 50 football pitches, short distances ensure efficient cooperation and a rapid exchange of experience – which is ultimately reflected in the quality of MAN engines.

Engine test

By manufacturing selected core components of our engines on site, we additionally ensure product quality and security at the highest level. Prior to series production, all engine lines are extensively tested on modern test benches – in addition, they are field-tested under everyday conditions and optimised for real-world use.

Function test

Each engine is subjected to a function test before leaving the factory: During the hot test, the engine successively passes through a performance, noise and leakage check. Furthermore, in 2006 MAN Truck & Bus was the first commercial vehicle manufacturer to introduce the modern cold test procedure, which tests quickly, reliably and in a particularly environmentally friendly way.

Basic technologies

MAN Engines, as a business unit of MAN Truck & Bus and thus part of the Traton Group, benefits greatly from the large-scale production experience gained in the construction of engines for commercial vehicles. Our enabling technologies and sophisticated components secure the future of modern engine series for all original equipment manufacturers.

Solutions for every application

MAN engines stand for maximum efficiency. We realise the lowest fuel consumption, best power densities and greatest reliability with a long service life through the use of modern cutting-edge technologies. In doing so, we optimise our engines for the specific needs of our customers. MAN Engines offers tailor-made solutions for every application and thus increases competitiveness.

Advanced knowledge

With around 100,000 engines produced each year, our customers benefit from sophisticated components, state-of-the-art technologies and our knowledge gained from large-scale production. This concentrated knowledge flows into the modification of our engines for the respective application and ensures their high quality.


MAN Truck & Bus is conducting intensive research into engine technologies that will sustainably reduce consumption and emissions. The permanent efficiency increase of diesel and gas engines – despite additional exhaust gas aftertreatment systems – underlines the high level of MAN Truck & Bus engine competence.
