Daimler doesn't say they're no longer developing IC engines. They say they're not developing fundamentally new engine families. The life cycle of the existing designs will support incremental improvements for decades to come. As noted, there's only so much we can do with the basic mechanicals. I imagine tweaks to combustion chamber, valve, and cam design will continue furiously for just as long, to support.....
Development of ever-more-efficient intake, induction, exhaust, and ignition control systems is still going strong everywhere. That's what my employer does. There's no indication that marine, heavy truck, OTR, off-highway, or equipment engines will vanish. Development continues furiously -- always aimed at improving efficiency, specific power, and emissions control. No doubt the development of better engine management systems for smaller engines will continue as well.
Remember that the single greatest reason fuel-burning engines make poisons and other non-optimum by-products is the process regime transitions as RPMs change. Support for a range of RPMs is nothing but compromise. Once the need to run at anything other than a single, optimally efficient speed is gone, it's possible to do things with fine-tuning an engine that are totally impossible when the engine is connected to the wheels, no matter how many gears there are. What do you do with that single RPM, super-efficient engine?
You hook it up to a super-efficient generator that also wants to run at the one single speed and you make electricity.
I believe fuel-burning engines will exist as the alternate -- and long range -- recharging system components of hybrids until such time as a system for storing energy at substantially higher -- read, orders of magnitude higher -- densities is found. And that, unfortunately, is still science fiction.
