One thing that always puzzled me was how the gas engines in hybrids were so efficient. Technology Connections has a great video explainer: https://www.youtube.com/watch?v=KnUFH5GX_fI
tl;dw: constant RPM and a weird stroke geometry where the power stroke is longer than the other strokes to extract more energy from the expanding gasses.
Like putting in the final optimizations in the crossbow right as others have figured out machine guns.

If we are able to consider fixed RPM operation and are willing to endure turbomachinery, I don't know why we wouldn't just go all in on a gas turbine. You can reduce the number of moving parts dramatically and accept a much wider range of fuels.
Being able to engineer everything around a one fixed operating speed makes a huge engineering difference. Reciprocating engines are responsive to load and speed changes, but there are trade offs in many other categories.
You can also make a gas turbine power module quite small relative to the alternatives. Replacing the it at major service intervals could be made economically viable.
Ironically, these solutions would be perfect for boating use, if only they used a diesel engine instead. Regular ICE will not go away anytime soon in marine world and I don't think they see the sales potential here if they developed their powertrains with that usage in mind as well.
This is coming out end of year in the U.S. in the 2027 Rogue. There will also be a gas powered 2027 with a CVT. It will be interesting how they compare, and also how the series hybrid compares to Rav4 or Corolla Cross with a parallel hybrid.
This powertrain is great for people that want to drive an EV, but they live in places with poor charging infrastructure.
Two motors and e-Pedal driving is the cherry on top imho (e.g. in the 2027 Rouge).
Hopefully it’s better than the second gen. Gas engine front only puts power to one wheel and electric rear only puts power to one wheel while the other two sit idle. Bad state for a mild 4x4 unless you keep it on pavement.
Nice to see the packaging improvements, but the modularity of the original leaf motor enabled them to be come a budget staple motor choice for ev conversion
Even more moving parts (turbo), and such a compact packaging... I wouldn't trust even Toyota for this
That’s all well and good, but can we get something other than a yet another fucking “an box” car with “slightly different headlights”?
this is basically the same as the hybrid system in the Honda CR-V, except the CR-V can clutch the engine in directly to the wheels at highway speeds.

I used to like hybrids, and obviously series hybrids are the coolest kind of hybrids, but now that I’m driving a budget EV, I honestly don’t see the point anymore. Just get the EV and skip the awkward half-way step that inherits the most expensive and complicated parts from both designs.
Seeing a sleek modern car pull away whisper quiet and then start the ICE 3 seconds later with a stutter and a puff of water vapor from underneath is the most schizophrenic sight, it somehow feels more dated than actual ICE cars.
Unless you live in bumfuck nowhere with expensive electricity, zero solar power and a daily 5 hour commute, an EV will likely work just fine for you.
