I am surprised more of the larger EVs don't have gearing to make them go further on a given charge rather than go faster. A 0-60mph time of say 5 seconds used to be classed as quite quick.... The 406 Mi16 in it's time might have had only 160bhp but a 0-60 of around 8 seconds seemed quick to me. My 330e could do 5.9s and that seemed quick. My A3, Skoda and 6 probably do it in around 8 seconds too. Plenty fast enough.
But I guess with an EV you can make it go quick easier than you can with ICE. And people are inclined to want such quick times.
I would imagine a Tesla Model 3 'performance' with different gearing could go much further and be in a lower insurance group. Lower top speed of course. And some ICE vehicles have now been capped at 112mph which is plenty.

I've looked at a couple of cars from one manufacturer who pledged a 180kph/112mph cap, the paperwork says different still showing 260kph.
It appears, for some markets, the limiter is being ignored if it hits sales.
I've written before NL has reduced the daytime speed limit on motorways to 100kph between 6am and 7pm lifting it back to 120 or 130 at night. I'm not sure if that will work in D if it impacts industries ability to function with sales folks driving between Düsseldorf or Hamburg and Berlin, Munich or Stuttgart. No doubt there will be an experiment which will be put in place and political pressure will be applied to remove it.
Edit: Just like the Tesla S model around 8 years ago the I5 is NOW quite the popular choice on my commute to work. Don't notice many EV6 though. Maybe Hyundai are doing better deals than KIA or the I5 has a USP missing from the EV6.

The EV6 is a flawed family car because of its low roof (blighted by a sunroof on the up-spec models) and its high floor-low cushion rear seat, which makes it spacious but uncomfortable. It’s a better drive than the Hyundai but long-legged German teenagers will be happier in an Ioniq 5.

So home now having driven about 370 miles today. I know that in various ICE cars past and present around the Pub that would not even be a tank of fuel, but cruising at an indicated 75mph on the radar cruise control, that translates to about 230 miles per 90% charge. That's about 66kWh and therefore 3.5 miles/kWh.
Today I charged up in Bodmin and then at Gloucester Services. Gloucester Services are lovely and much much nicer that the usual rubbish. Branded Westmoreland, I suspect they are part of the Tebay Group?? Very smart, real food, no chains and excellent charging facilities.
The charge speed of the I5 is welcome. I got 175kWh yesterday, 140kWh and 150kWh today. The e-Niro owner next to me could only marvel at how quickly I added miles. A maximum charge speed of less than 100kW is painful to watch.
I concur with Dubya.. The 'economy' doesn't take too much of a dive after 65mph until you get towards 80mph. The difference in indicated range between a 65mph cruise and 75mph is not a large as I would have expected. Probably lose about 10%

Lots of hills in NZ, frequent blustery (head)winds, and lots of braking/accelerating, as you shall see Esp! Shame you can’t rent an EV similar to your own when you visit NZ; the comparison and your impressions would be interesting!
Lots of good roads in the UK, albeit heavily trafficked!

It’s a better drive than the Hyundai but long-legged German teenagers will be happier in an Ioniq 5. Counterintuitive, innit, because the EV6 looks like the bigger, longer family car, so my assumption is greater legroom and more boot space than the I5. Whaddaya know.

I remember the first time I put my first Leaf on a 50kw charger and marveled at how quickly my percents were going up.

It's like comparing broadband speeds. Gigabit is nice but who actually needs it ? No good the car telling you its full and you're about to incur excess parking charges for hogging a charger mid-stream.

Yes, the Leaf (and the Model S) showed what was possible and where the improvements were needed. Those improvements have pretty much happened now, and what remains to be done is mostly about scale and affordability.

No good the car telling you its full and you're about to incur excess parking charges for hogging a charger mid-stream. Doesn’t really happen that way, though, given the usual tail-off above 80 percent. You’d have to be pretty inattentive (or inexperienced) to let it overrun. This was mine at an Ionity 150, suggesting the car rather than the charger applied the throttle at 80 percent.

That chart shows a charge time of 44 minutes, my EV with max charge rate of 77kW took 48 minutes to load to 100% albeit a 64kWh battery. I wouldn't do it to 100% now.
It shows buying the car which gives you the space, range, performance, efficiency, whatever, is more important than the charge rate as the time at the charger is similar.

Esp has far more experience of DC charging than me — I’ve done it maybe a dozen times to three cars over seven years — so I can only guess what was restricting that post on that day before it reached 80 per cent. I used exactly the same one a week before and it behaved similarly, as did the Gridserve 150 at East Midlands.
But, as we’ve been saying for ages, efficiency is what really matters, because that’s what turns the input of percentage or kWh into the useful outcome of travelling distance. A 280Wh/km Etron or a 260Wh iPace will take a lot longer to achieve that Esp’s 170Wh Ioniq 5 or even my 200Wh iX, especially if the promise of superfast charging rates is seldom delivered in full.

It's how EVs work you will never, ever see 200kW or whatever from 20% to 80%. Initially some charge energy will be used to get the battery to optimum charge state, between 40% and max. 60% you will see full throttle charging either restricted by the charger or the BMS in the car. After 60% it will be on a sliding scale, above 85% is effectively a trickle charge reducing to protect the battery chemistry.

I would really like to do that. I wonder if they rent EVs? Like I did last year from Hertz at Newquay? And where did all those Polestars go?

After 60% it will be on a sliding scale, above 85% is effectively a trickle charge reducing to protect the battery chemistry. The new I5 has pre-conditioning (selectable as well from a button in the cabin) so the battery should be at optimum state ready for top speed charging when you arrive. My car can take over 225kW, so to mythical 10% - 80% is doable. Frankly I don't get down to 10%, and the 20% - 80% is certainly easily acheived in 20 minutes with the right charger. In fact the slow down from 80% to 90% is modest; yesterday from an average of say 140kW to about 80kW. The coffee and pee stops yesterday with a few minutes added on to drink the coffee made a huge difference to my journey. I arrived home feeling very relaxed. If I had done it in one go without stopping I think I would have been far more tired when I got home.
