Cover Stories
The Lightweight Forging Initiative – Phase III: Material Lightweight Design for Hybrid Cars and Heavy-duty Trucks by Georgsmarienhütte, fka Aachen, Hirschvogel Automotive Group
It is easier to talk about realizable lightweight design potentials if they are demonstrated on the basis of a definite, representative vehicle. In its third project, the Lightweight Forging Initiative with an international partner structure shows which lightweight design potentials lay in a split-axle hybrid car and in sub-systems of a heavy-duty truck. The results for drive shafts, shock absorber, wheel carrier and connecting rod include weight savings of 23 to 35 %.
Added value is decisively for lightweight design by Thomas Wolff, BMW
The Head of the Lightweight and Technology Center talks in an interview about how added value can be achieved through lightweight design and where the biggest levers for lightweight design can be found in the daily work of engineers.
Lightweight Chassis Concept with Potential for Mass Production by Ford-Forschungszentrum Aachen
In a two-year project led by Ford, a fiber composite knuckle and the tools required for mass production were developed. New CAE technologies were devised and components manufactured using a multi-material manufacturing process applied for the first time in the automotive industry.
Evaluation of the Noise Quality of Auxiliary Systems on Test Benches by Head Acoustics
Against the backdrop of vehicle electrification, the noise and vibration quality of auxiliary systems is becoming increasingly relevant. The powertrain now makes less 2 noise across narrower frequency bands and in a higher frequency range. The elimination of the combustion engine belt drive means that optimized operating strategies can be implemented; however, they are no longer linked to the driving condition. Head Acoustics examined unexpected audible state changes that also lower the perception threshold.
Chassis Application with Integral Controller and Virtual Methods by Audi
The driving dynamics genes of an Audi are based on a passive base chassis and are essentially defined by the functional software of the active chassis systems. Applying brand-specific driving characteristics to the increasing number of vehicle models and variants forming part of the company’s marketing strategy entails increasing commitment to chassis tuning. New electric drive trains are adding to the complexity. The aim at Audi is to manage this additional complexity in the product creation process with reduced resources.
Requirements on Brake Boosters for Automated Driving by LSP, IPGate
With automated driving, ESC systems and brake boosters become even more important than before. The engineering services provider LSP faces up to this trend and compares electro-mechanical brake boosters considering an increasing degree of SAE automation levels. As a new development, the compact brake booster X-Boost, featuring a very light and narrow design, is presented in detail for the first time.
Adsorption Stationary Air Conditioner without Compressor for Commercial Vehicles by Mahle
To provide the driver with pleasant temperatures in the cabin during rest periods, truck air conditioners also run when the truck is stationary. The required compressor is driven directly by the engine. High exhaust and noise emissions as well as new legal regulations, however, make this procedure more difficult. Mahle has developed a system that cools the driver’s cabin noise-free, wear-resistant and efficient.
Range Extension of Plug-in Hybrids Through Thermal Management Measures by Eberspächer, Fraunhofer ICT
There is still great potential for saving fuel and energy through optimized thermal management. A study by Eberspächer and the Fraunhofer ICT based on virtual examination has analyzed the impact of various technologies and measures.

Dr. Alexander Heintzel
Editor in Chief
For 120 years, ATZ - Automobiltechnische Zeitschrift has been presenting cutting-edge solution concepts in automotive development and the very latest information for the everyday work of engineers relating to every aspect of the complete vehicle – whether it is the chassis or body, lighting technology or NVH, packaging or thermal management.
High-level articles from practice and research enriched with interviews and reports from our editorial team are perfectly matched to the needs of the target group and the latest topics that concern them.
The technical expertise of the editorial team and their networking skills enable them to quickly pick up current trends and topics on the market and to support an optimum technical orientation. This makes ATZ the ideal technical magazine for technology-oriented management and young engineers in the automotive industry and it is an indispensible medium for the targeted further development of automotive specialists.
Throughout the year one of the world’s most distinguished magazines on automotive engineering focuses traditionally on topics from powertrain, chassis technology or active and passive safety. Also valuable information out of the field of aerodynamics, simulation and testing as well as materials and light weight design play an important part in the magazines topic-list. Recently globally most prevailing matters like Car-to-X-Technology, autonomous driving, Connectivity, HMI or grid integration and E-Mobility are gaining an increasing importance within ATZ.
