The people behind the TGX D38 - Dr. Rolf Döbereiner

The TGX D38 is MAN’s new flagship. Many MAN employees poured all their skills and passion into developing the new truck. We introduce you to a few of them.

Pride – that is the word that best describes what ties many employees to the TGX D38. The new top-of-the range truck model is taking center stage at MAN’s trade fair appearance at the IAA Commercial Vehicles 2014. The new flagship adds horsepower of 520, 560, and 640 to MAN’s range. The top model offers a customized driveline with numerous new efficiency functions. At its center is the newly developed D38 six-cylinder in-line engine with 15.2 l displacement. This engine stands for superior power and gives the TGX D38 maximum torque for all needs – without breaking any horsepower records. When it comes to this vehicle, the MAN engineers instead concentrated their efforts on reliability, efficiency, and lower operating costs.

But how much work goes into a vehicle like this? And who are the people behind the product? At MAN, several teams worked on developing the new vehicle over a few years. From development of the engine through launch of the truck – many MAN employees poured all their skills and passion into developing the new truck. That is reason enough to speak to some of them and show the team’s work. What ties them to the new vehicle? What role did their team play?

A short interview with the people behind the TGX:

Head of Transmissions and Cooling System Development

What does the TGX D38 conjure up for you?

We were involved in designing the TGX D38 from the very beginning. And of course, every time one makes a contribution to the development of a vehicle, it conjures up something special. However, the TGX D38 has once again made us especially proud because it´s our top-of-the-range product.

What was your team´s contribution to the vehicle?

Up to thirty members of my team carried out the development work "behind the engine", namely installation of the gearbox, fine-tuning of the transmission system and its application, as well as the cooling-system design and validation. We´re really proud of the new MAN TipMatic 2 gear-shift system that always selects the right gear for the driver and, thanks to new gear functions, offers even greater efficiency coupled with high output. At the same time, the new cooling system operates effectively, demonstrating how intelligent control strategies can be realized in a vehicle to the benefit of our customers.

What´s so special about the new TGX D38?

The TGX D38 has an especially efficient powertrain to ensure excellent fuel consumption and lots of mileage. Our new gear functions make it easier for the driver to carry out his daily work. The developments integrated into the TGX D38 show that today, new standards of power transmission engineering can only be achieved based on teamwork. We have successfully achieved this as a result cooperating closely in developing the powertrain, from the engine to the axle.
