Blah blah

I'm not wasting any more time on your childish statements - goodbye

Actually the 'lugging about a battery' bit isn't quite correct. When the battery is 'empty' on a PHEV there is still retained charge to provide full power if required and the vehicle runs as a full hybrid until recharged. Running as a full hybrid will still be much more economical than an ICE petrol car even on motorways. As an example our Kuga PHEV will do 50mpg on the motorway which the Kuga ICE can't get anywhere near, the difference is even more stark on non-motorway running when regenerative braking plays a large part.

I am referring to steady state driving there is no push from the E or very very little at least on the Beemer I had. It would be only on overtakes where it would activate

Highway speeds I was getting around 33mpg.

If they could do hybrids with true 100km E range that would be very good

How’s this: 0-60 ev, 45+ ice assist, 65+ ice idle

There are now some PHEV's with around 100km real ranges including the BMW X5 50e

In the Kuga PHEV/FHEV there is always a blend of electric and ICE in hybrid mode (very similar transmission to the Toyota system), especially with the CC on, with regenerative braking on downhill sections which is then used on uphill sections. Hence the very impressive consumption even when the PHEV battery is 'flat'.

45+ what?

65+ what?

Which car are you talking about?

Honestly you just post drivel

Interesting you are capable of comprehending parts but fail to see the whole.

Evs are great at acceleration but heinous at maintaining. Ice is heinous at acceleration (well not really but for the comparison yes) but great at maintaining. At highway speeds (since we’re only permitted to go as fast as they allow because they said it’s better for the environment - but we won’t go there) ice can generate a decent amount of electricity, even at idle but we’re cruising along at 2k+/- . Since we”re more or less shooting for 0-60 being ev that takes care of the city driving. Now no more ‘but the average trip is only blah blah’, a dual system seems to be more practical. existing infrastructure is leveraged, jobs are created and maintained.

If you wrote things in a complete way rather than just bits of random information it would be easier.

Don't agree with your overly simplistic assertions above. No evidence presented for your 'opinion' either - please provide information that EV's are heinous at constant speed driving (which rarely occurs)

As a clue - you may want to consider aerodynamics which are by far the biggest factor at cruising speeds and apply to both EV and ICE in the same way. Thus similar power required, which then comes down to drivetrain efficiency - that will provide the answer! An ICE always uses far more energy for everything because it barely gets to 30% efficiency from the fuel.

Momentum minus drag

Momentum minus drag

What is? - Come on, try more than just 3 words to explain yourself.

If you want to know the energy required to keep an object such as a car moving at a constant speed, then momentum has nothing to do with it.

Momentum = mass x velocity, so to maintain a speed you need to keep momentum the same. What you are actually looking for is the force required to counteract the aero drag (mostly, although other things such as rolling resistance also play a small part as we know from tyre design)

Momentum - drag is what happens when the vehicle is coasting with no power and slowly comes to a halt.

Momentum has everything to do with it hence your point in para two. And is what you explained resulting in momentum minus drag in para two. Drag is what causes the object in motion to slow?
