Such engines are known as more efficient and more powerful than conventional four-cycle eingines. The only innovation in VW engine is that it has opposite cyliders. But still such engines has well known disadvanges. Especially, if they won't find new lubrication method other than injecting motor oil into combustion chamber, it won't be attractive taking into consideration recent emission restriction. After all, construction of such engines demand from them burning motor oil! Moreover, it won't let you to break by switching lower gear, because such breaking would cut injection off and hence cut lubrication off. Saab (I don't rememner when) took two-cycle engine, cut injection off and started to rotating engine, after 20 min. engine was seized up. If they overcome somehow these usuall disadvantages then maybe it will be something interesting. Up to now, I treat more siriously idea of turbochaged 3 cylinder engines in lighter cars with recycle of breaking energy, start-stop system, new aerodynamics as better strategy of making economical, ecological, efficient car.

But the 23kg is really not a lot, hopfully their return on invesment is worthwhile. It’s interesting to see that my presence in the car adds 0.3l/100km consumption.

Maybe it's a good tradeoff in applications where stiffness is key. Hardening the steel will make it stiffer but more brittle and will damp vibration less.

So which 8 models will it be? 5 GT, 5er, 1er, 3 Sedan/Wagon, 3 Coupe/Convertible, 3 GT, X3, X1? “Over the next three years, eight more new BMW models will incorporate components from the facility.”

It doesn't sound like much - 23kg in metric speak, but it is a step in the right direction. I wonder how much weight can be shed with future technologies. Would it be possible to produce a GT weiging, say, 1500kg (3309 pounds)? Now you’re talking! It doesn’t sound like much – 23kg in metric speak, but it is a step in the right direction.
