Hi

I see the new Quahqai will come with nissans e-power train , this looks quite interesting.

Done some reading about it , but what do people think about this.

It’s a very popular option in Japan on the new Note. Sales more than doubled.

How exactly does it work?

petrol engine charges the battery, which in turn powers the EV motor.

The petrol engine does not directly drive the vehicle, so a bit like Mad Lad's Rex

Kind like an Ampera so?

No, an amperia is a phev, epower is a generator and a battery, no plug in at all.

There's a few of the notes about, very efficient, but its a. Note so it's not great to drive, quashqai will be pretty much the same to drive as is but much more efficent.
Think the note will get 70 - 80 mpg real world, so I'd say the quashqai will get like 60-70?

Is this akin to a scaled up REX?
Is there much of an actual benefit to MPG and emissions?

My understanding is the note has a small battery 1. 5 - 2kwh. The generator powers the battery constantly as 2500 rpm, and I think rev to keep minimum charge on the battery at allltimes for power.
I beleive the note has 120bhp ish and get 70-80 mpg, aperantly super reliable, like all ev / hybrids.

Can't see th not being good and selling in droves here, cheap to run, cheap to tax, meh to drive tho.

More like a scaled down REX, the battery looks to be tiny on the quashqai.

In a REX, the battery is the main source of power, it should have sufficient power to handle a days driving and can fast charge if required. The generator acts as a backup if needed

The Nissan system mentions the petrol engine is the main source of power. I'm guessing the idea is that the petrol generator can operate at it's most efficient setpoint and the battery handles any extra power required

So in short, maybe a little bit better than a conventional hybrid, depending on how it's driven

Worse than a PHEV though because you can't recharge it

Now, if they put a 40kWh battery pack with rapid charging in it, then you'd have a whole different kettle of fish
