Re: The fuel consumption of the PHEV and how I decrease it.

Obviously the same over here. My observation is that for safety reasons to the engine, it runs in kind of stand-by mode for a few minutes at the beginning to heat up material and fluids before tieing it on to the wheels. Then it increases power and works as expected.

We were down -10°C these days. The whole car had been cooled down for about two days. I started with the ICU from the beginning to take the advantage of the ICU warms heating up the car right from the beginning rather than burning epower for that. Again, it started with a slowed down running engine, obviously not involved in driving the vehicle at all. As the bar in the display wasn't moving in effect to the foot pedal push. After a few minutes it seemed having warmed up and took over control. Effect could be seen in the SOC having lost one bar in the display by then. It, then, even took another few minutes before it activated parallel mode within the defined speed range.

The route planned was longer than SOC reach. It would have eaten up the SOC along the way. I ended up with an empty SOC and 6.5 l/100km. That's 2 litres more than on fair mid temperatures. It was just right to start with the ICU right from the beginning. I can't tell if it heats up the batteries in the background too to achieve better performance.

My experience is that the car does it really well considering conditions. A very well thought out system overall.

Re: The fuel consumption of the PHEV and how I decrease it.

[How can I force my vehicle to run in parallel hybrid mode runnig in the highway. I find series hybrid mode to be not very good in highway conditions]
As long as it's not too cold and the battery is not fully charged, putting it in Charge Mode usually makes it switch to parallel mode. I do that going up hills on the highway since it keeps the ICE from revving too high. It doesn't actually charge much uphill as most of the ICE power goes to maintain speed. Then, Normal mode downhill, and Save Mode on the level.

Re: The fuel consumption of the PHEV and how I decrease it.

The posted graph showing diff between torque needed to drive and max torque is interesting!

I am curious, what happens if I towed 6000 pound boat for 40 minutes? How does the graph look like? Would it exceed the max torque generation?
Would the torque/power generation system be able to cope and pull it without depleting faster than it is draining?

I am contemplating a replacement car to my current small Gas car, and am researching whether something like 19` GT is a good choice, in Canada so cold weather about half the year.
