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:
Dr. Ulrich Wiebicke
Testing Manager for D38 engines at MAN performance and emissions/testing
What does the new D38 engine conjure up for you?
I´m proud of the engineering expertise that´s gone into it. The D38 engine is a reliable, powerful and efficient power unit. For the engineers involved, it´s more than just an engine - it´s the result of several years of development work and a great deal of effort.
So what did your team contribute to the TGX D38?
No expense or technology was spared in the development process, just weight. The D38 engine is 160 kilograms lighter than the D28 V8, which it´s replacing. It also consumes less than the most powerful D26 Euro 5, yet still offers an output comparable with its predecessor that is always accessible, as well as plenty of traction. In all, around seventy people have been working in the project team to refine the engine – whereby every detail has become very dear to us.
What´s so special about the new engine?
The greatest know-how of MAN engineers has gone into this engine. We´ve bundled the experience gained from MAN´s history of engine construction and combined it with new ideas. For instance, MAN´s D38 is designed for an ignition pressure of 250 bar and operates with an injection pressure of up to 2,500 bar. Thanks to its two-stage exhaust-gas turbo-charging process, maximum torque is available from as little as 930 rpm, so that combined with a long axle ratio, the vehicle can be driven extremely economically.
The new in-line six-cylinder engine in the MAN TGX D38 achieves top marks.
MAN’s designers have long concentrated on assisted, safe driving. A large number of assistant systems have been developed to date.
