The Vienna Motor Symposium has always been a forum on which not only VW has presented ideas and plans. The current is about fill the waiting time for the breakthrough of the electric drive with news.

No, the combustion engine does not seem to be finished yet. They even rely on the diesel engine, with another 9 percent reduction in emissions and 10 g/km less CO₂. Presumably, a mild hybridization does not have so much advantage. So it has to stay with the 12V belt starter generator. Two liters of displacement perform between 100 kW (136 hp) and 150 kW (204 hp). A little later perhaps, the engine is also in the modular transverse box available, probably in a smaller displacement version.

With even more electrical attributes, the other internal combustion engines are on top. They all gradually get a hybridization with 48 volts and LiIo battery. This was to be expected because it makes the next CO₂ sublimations much easier to achieve. Already the Golf 8 should make the beginning, to start electrically, to boost if necessary and to recuperate vigorously.

Natural gas engines (picture above) emit virtually no particulates and significantly less NO_X than even gasoline engines. The CO₂ output is comparable with the diesel engine, so there remains only approx. 10 percent more consumption. Optimized by VW further, with 48V hybrid system and dual-clutch transmission perhaps a little less.

Which is not always clear, the natural gas part does not work with the direct injection of the gasoline part, but blows into the intake manifold (see very short scene in the first video). By omitting the gasoline part one could save a part of the enormous additional costs. Perhaps then through controllable charging the high octane of natural gas can become even slightly more efficient.

Perhaps one could drive in view of at least 900 gas stations only with an emergency gasoline part for cold starts or through technical development without any. Hydrogen tanks allow up to 700 bar, why not increase the 200 bar of natural gas tanks and thus the range? There is probably even more potential for development in the natural gas engine, once it has gotten rid of the mortgage of a bivalent engine. 04/18
