The thing I don't get, is why aren't the trucks doing Hybrid yet?
They are already big and heavy so the weight overhead isn't really a big deal.

They are doing a lot of steady RPM driving where they have more power available then their max speed allows em to do. It's not like passenger cars where a heavy foot kills the gains.. especially not on long hauls..

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.
