Powertrain Development

By 2050, the plan is for mobility to become carbon-neutral. To achieve this goal, the course must be set here and now. IAV is not only in full command of all drive systems but also understands the entire vehicle. The result are optimum technical solutions that are also sustainable.

The path to future carbon-neutral mobility is the key focus of powertrain development. It is not only keeping OEMs and component suppliers busy, but also occupying the minds of politicians and society. At least for a long transitional period, various options will exist side by side. In addition to conventional combustion engines (some powered by gaseous or synthetic fuels), we will also see hybrid and battery electric powertrains as well as fuel cell drive systems. The change has noticeably begun: to a large extent, new combustion engines are already hybridized, and electric mobility is gaining momentum across the globe.

For OEMs, this is a major challenge. They must decide on which powertrain combination to use if they want to meet ever stringent CO2 and emission regulations in the coming years and decades. IAV has both broad and profound expertise in this field. We have been focusing on all types of drive systems for over 35 years and, in cooperation with our customers, can find the optimum solution for future vehicle fleets because our experts not only understand all of the various technologies involved but also the overall “vehicle” system. They give consideration to the entire life cycle of a product (well-to-wheel, ideally cradle-to-grave) and, in this way, arrive at solutions that are sustainable in every respect.

„Over the next few decades, different powertrain technologies will co-exist because urban, suburban, interurban and rural mobility need to serve different requirement.”

Wolfgang Wukisiewitsch — Executive Vice President Powertrain Systems Development

In addition to our 7,000 top engineers, this is also attributable to our modern development tools. IAV Mobility Synthesis lets us compare various mobility scenarios, with customer acceptance playing a key part. For given CO2 and emission targets, IAV Powertrain Synthesis finds the optimum powertrain mix for a vehicle fleet from millions of alternatives. Tools for combustion engines, electric drives or transmissions lead to optimization at component level. Virtual development methods are providing the key to coping with the sheer diversity of vehicle variants and to shortening development times. Our high-end testing facilities – including a high-altitude climate roller dynamometer and numerous test benches for electric drives and battery systems – guarantee that all IAV solutions are fully validated. To defend our leading position, we cooperate with universities and research institutes. We organize events to foster dialog within the industry, such as the Berlin Powertrain Symposium.

In our development projects, we work on an interdisciplinary basis using the expertise of our colleagues from all IAV departments. In this way, we analyze the potential of new fuels as well as the characteristic properties of different energy storage systems. IAV not only delivers first-class components but complete systems in which everything is perfectly matched. In terms of powertrain systems, this makes us the premium engineering partner for all prominent OEMs – from advance development to volume production, regardless of whether the focus is on combustion engines, hybrid or electric drives. The vehicle size doesn’t matter because IAV’s maxim is: from mini to maxi! We are as content to focus our attention on small passenger cars as we are on heavy commercial vehicles and work machines.

In the past, our developers have shown that they can reliably take innovations to the level of manufacturing readiness. This is demonstrated by millions of vehicles in which IAV solutions prove their worth every day, even under the toughest of conditions. Today, the spotlight must be on setting the course for the vehicle fleets of the next five to ten years – preferably with a partner who understands the diversity of powertrains and the overall “vehicle” system with equal proficiency.

„Vehicle fleet makeup by 2050 will not only be determined by regulations but also, and to a very large extent, by end user acceptance of competing technologies.”
