Thanks, bpg. I'm a bit confused over your "Edit: 27kWh/100 miles is 3.7 miles/kWh". Sorry to be dense, but how do we get to that? It sounds like that's the figure I'm conditioned to expect.
Ach, I'll leave that as a sign of my own denseness. It's just 100/27, innit. Sigh.
But yes, agree with Alanović, EV miles are (for me) about half the price of petrol ones. Each day petrol goes up, the EV miles price is better, as my electricity is fixed until next April.
All of which is getting away from Espada's lovely Ioniq. I hope it's turning out to be one of those cars you look at on the drive and you think "yep. I like that. Maybe I'll go and buy a pint of milk in the south of France this afternoon".

The inside is. I gave up trying to work through the bug yesterday, wrapped myself in a blanket and coughed my way through the silly but engaging Murder in Provence on Britbox. That features Roger Allam — who I want to be when I grow up, and not just because I envy his hair — and this. Didn’t know these had frameless windows too but this one does. And it’s brown. (Pardon the low-quality screen grab.)

Edit: Where do you go for a supercharger rebuild, or more specifically the parts, for one of those Al ? Did Nissan or Datsun ever do a supercharged model in the UK or Europe ?

Speedo reads all the way to 180kmh - so 112mph. That supercharger is doing what precisely??

Japanese law, everything is restricted to that. If you buy one outside of Japan you can remove the restrictor.

The restrictor presumably doesn’t affect acceleration, which is the real-world purpose of the supercharger.

Funnily enough the limit only applies to the home grown stuff. Imports do not have to comply. Usually implemented through a fuel cutoff so yes, you get the benefit of turbo and superchargers at lower speeds.

I have driven from Manchester to Leyburn in North Yorkshire today via Kirkby Lonsdale. A total of about 130 miles with an average economy of close to 4 miles/kWh. Nearer to 3.5 miles on the motorway and over 4.2 miles on the country roads. This means my range on the motorway is about 250 miles but over 300 miles if I do cross country driving; so a different dynamic to ICE cars where motorway driving is far more efficient. Presumably this is down to lots of coasting down hills and regenerative braking.
I did a mid-trip recharge as we stopped at a Booths supermarket in Kirkby Lonsdale where they had 50kW Instavolt chargers. Very handy as I topped up to 100% whilst Espadrille was shopping...
Very happy so far. Done about 700 mile so far in the car and will report at 1,000 miles.

Aerodynamics are one element, another is gearing. BEV has a one size fits all gear. ICE has gears optimized as far as possible to keep the engine in the ideal range e.g. <2000 rpm @ 80mph for both petrol and diesel. That was unheard of when I started to drive, petrols had to rev because they didn't make much torque and were buzzing away at 3,500rpm @ 60mph.

Yes, in the sense that a fossil engine has to waste revolutions at lower speeds by turning them into fewer units of distance travelled. (Although with a correspondingly smaller ‘throttle opening’ — see the much-discussed fallacy from the manual days of using fourth gear at town speeds to save fuel.)
Still a small effect compared with shifting air. The same vehicle travelling at 70 distance units per time unit requires twice the energy input compared with 50 units. The ratio of motorway average to B-road average could well be even more. Esp is right about regenerative braking, in that an EV has it and a petrol car does not, so it wastes less motion as heat on a twisty road. But it is not enough to explain the difference between country-road and motorway consumption.
Gearing is one of the features developed to work around the inefficiency of internal combustion. Esp’s EV — and yours and mine — will have the highest transmission ratio that can still move the car uphill from rest, possibly adjusted downwards for optimum usable acceleration. That’s not so much one-size-fits-all (in the usual sense of unsatisfactory, that’ll-do compromise) as one-size-is-all-that’s-necessary, just as a steam locomotive (which has a flat torque graph like an electric motor) has no gearbox, just small driving wheels for heavy traction or big ones for top speed.

Returning home today. More downhill than Friday and regeneration is very impressive. Not only added range but actually increased the charge in the battery.
Working out that playing with the regeneration levels whilst driving is advantageous in maintaining speed and maximising regeneration.

Yes. Although, as always, not putting on speed you’ll soon have to lose is the best strategy. You got better efficiency out of your 350 CDI than I do in mine, so you must already be quite good at that.
Do you have clicky paddles for managing regen, like the Enyaq (but not the iX3)? Seems like a natural design choice, given that many of us have got used to a quick click to enhance engine braking from an ICE.

Clicky paddles - yes. Very intuitive, especially for someone used to them already. Espadrille's Mini lacks them and it's infuriating.
