The Electric drive could then boost them when they need the extra torque
When does a truck polute the most? when it's accelerating, climbing and doing a lot of stopNgo traffic (Tjams, city red lights)
So why don't they go for smaller engines
make up the difference with the hybrid electric drive?
Surely that would be instantly available technology that would reduce their emissions a huge amount. And no worries bout long range autonomy or charging infrastructure , electric network required.. truck charge farms..
It would simply optimize their torque requirements and their emissions.

We have had hybrid city buses for two years. Stop and go is basically only thing buses do, so there is lot gain to recuperate braking into battery.
Trucks on the other hand do mostly steady speed (at least in Sweden, Holland is much smaller) so it is just not worth hauling batteries/inverters and motors if you gonna burn diesel anyway.
Latest development for trucks is going full electric and/or hydrogen with some pantographs available at certain highways. Anyway, I hope we can ween ourself of Arab/Russian crude ASAP.
