I agree that fuel is the prime mover, and improving the combustion process is the source of the most tangible gains. In addition to peak power, which is what we're talking about, there's sustained power, as you state, in certain cases it's better to use electric mode. Would the MGU-H be more important on a track like Baku, or Silverstone? I know in places with a lot of full throttle, like Shanghai the Honda engine lacks behind the others. Is the lack due to being unable to harvest enough energy from the MGU-H? Bahrain has a lot of heavy braking so plenty of chance to harvest with MGU-K and H through extra harvest, and the power seemed to be reasonable there.PlatinumZealot wrote: ↑Thu Jan 17, 2019 2:42 am
My analogy is good. You aren't looking at it right. The "power plant" would be the ICE itself.. and the "electric car" would be the battery. You will lose more energy going from engine to mguh to battery to the wheels, than going from engine to straight to the wheels. As I said before you cannot look on it as snapshot in time, but over the length of the lap (energy not power). How much energy do you have and where do you want to use it. The Electric car... the energy is stored and can be released on demand... and can be overall more efficient "over the lap" but in not all cases.
If harvesting from the MGU-H is a load on the turbine, then does it not also put a load on the exhaust gases, and by extension increase back-pressure? How much power does this increased pumping load cost in terms of crank power? Granted it costs less if you have more ICE power to start, but if you can't harvest enough exhaust energy you will always be at a deployment disadvantage. Deployment isn't just for power, it also affects power delivery and corner entry.
Please see that Ross Brwan's comments on electric vehicles are similar to mine.

RB: If I'm honest, I don't know. I don't think any of us know where the automotive world is going to be in five years' time. There is a massive enthusiasm for electrified vehicles, but they have massive challenges as well, and is there an evolution that is going to come?
If you look at the way electricity is generated in the UK, the pollution from an electric vehicle is still very similar to a very efficient, small petrol car because that electricity has to be generated somehow. We are not generating the electricity that is needed by renewables in the UK at the moment, and that is with the electricity we are using at the moment. Imagine if everyone used electricity to charge their cars. So there are some massive challenges ahead, and I think there are still avenues with internal combustion engines that are worth pursuing.
