Only a 125mph top speed with over 500bhp? That won't make you very competitive on the M69 will it?! 
The X-Power hits a proverbial brick wall at 118. Guess they've tweaked it a bit. Still pulls reasonably hard all the way to the limiter. Guess it would need a 2 speed box ala Taycan to hit a natural limiter.
Most of my cars have had a relatively modest power and if they haven't then they've weighed 2.5t.
But it's amazing how quickly you get used to 400+hp.
Struggle to understand these people that say you can't use a 500hp daily in this country. Granted I do a lot of driving between 0000 and 0600 but even without that advantage having that point and squirt ability is great. Most normal cars I drive now feel broken in comparison.
I reckon this'll be quite a good car. It really wouldn't take much to turn the X-Power into a great car.

Yes and I'd imagine this to be pretty quick to a 100mph and the quarter mile for sure. Although it could get a bit embarrassing when something like a Mini Cooper S flies past you at 125mph though I reckon!
Who the hell drives at 125mph+ anymore.
If the top speed is a genuine concern, good luck holding onto your licence and possibly your freedom.
As you say though, with the traffic volume now/speed cameras/smart motorways etc, you'd do well to actually get to 125mph in the first place realistically in fairness.
Plus it is only a bit of good fun banter with a few other folk on here who used to enjoy driving at high speeds like I did really.

Most single gear EVs are intentionally designed with a limited top speed.Guess it would need a 2 speed box ala Taycan to hit a natural limiter.
It makes the car cheaper to manufacture and more efficient at normal speeds.
There is no need to design in fixed aero features to prevent lift that then also increase drag at 70 mph or to use tyres that might increase rolling resistance to survive at higher speed.
It also often allows the motor speed/efficiency map to be better matched to the cruise torque demand at normal road speeds.

I'm just from a time when most performance car owners did used to absolutely tank around on motorways that's all. So the top speed of a car is always something that I look out for(and it is one of the reasons why I went off Volvo with their limited 112mph top speed for example).

It would easily see 125mph on a longish on ramp. As you say though, with the traffic volume now/speed cameras/smart motorways etc, you'd do well to actually get to 125mph in the first place realistically in fairness.

I suppose it was at much a questions a statement, the last time I saw any car doing over 120 mph on the roads or motorways anywhere around where I live it seems like long before covid.As you say though, with the traffic volume now/speed cameras/smart motorways etc, you'd do well to actually get to 125mph in the first place realistically in fairness.

Granted, I'm a sample of 1 not doing a particular high mileage.

What would be the limiting factor then without the electronic nanny? It makes the car cheaper to manufacture and more efficient at normal speeds.

I guess a theoretical top speed for my X-Power would be around 170 but would the motor run out of rpms before then?

Let’s be honest it’s probably fair to say there is a reason most people in the real world actually prefer German cars and why the Germans can charge more
Certainly is - marketing, image, and past glories. It’s a good job all that Jap crap never made German engineering look second rate. ChocolateFrog said:

Assuming the tyres don't fail, the car doesn't take off and the motor's final drive ratio is adjusted to allow for higher speeds, then the limit would be when aero drag power consumption exceeds the motors power rating.I guess a theoretical top speed for my X-Power would be around 170 but would the motor run out of rpms before then?
Some additional power is require to overcome rolling resistance and actually accelerate the car.
There are two very simple rules-of-thumb for those two elements both of which are mass and speed derived:
6 bhp per ton per g per mph for acceleration power.
6 bhp per ton per 100 mph for rolling resistance.
For a 2 ton car (i.e. your car with driver and passenger) at 200 mph, just 18 kW is needed to overcome rolling resistance.
The drag power, which depends on air temperature and the car's CdA, increases with the cube of speed.
320 kW, all things being optimum and with enough road to creep up to it, in theory may just get you to 200 mph, the issue is of course all the engineering changes to do it safely.
In practice it would top out below 200 mph.
Energy consumption would drop to well below 1 mile/kWh, more like 0.65 miles/kWh, and the range would drop accordingly.
In winter, the air is more dense and the car is less efficient anyway, so the top speed and range would be noticeably lower.
This chart shows the power demand, more than 90% of which would be aero drag, I've made an assumption about the CdA value, CBA to look it up, apologies

Worth noting that this is very much an approximation because it assumes that airflow attachment doesn't change significantly over the speed range. In reality Cd is not a fixed number. For example for "fastback" type cars there is often a big step up in drag at whatever speed the airflow detaches from the rear window, effectively doubling the volume of the vortex behind the car. otolith said:

People are welcome to boycott goods from whatever nation or manufacturer they choose. They might not want a Ford or a Tesla because of America's various foreign policies and support of Israel (or indeed the manufacture of UK bound Teslas in China), they might not want a McLaren because of Bahrain's human rights record. They might not want a VW group car because of dieselgate or a Japanese car because of whaling. There's a growing movement to boycott India over their behaviour towards Bangladesh, so that would be JLR out. I know some people who still won't buy anything from a Nestlé group company or use Wetherspoons or Dyson because of Brexit. If you want to boycott Chinese goods, that's really up to you - I dare say you are also boycotting other countries with ethical issues.

There does seem to be quite a strong pattern on PH of people who cared not one jot about the human rights of the people who made their TV, clothes, Amazon tat, computers and gadgets, the oil and gas they burn, or anything else they consume and neither did they give a damn about the environmental impact of these products, but when it comes to EVs they insist on only the most ethically sourced and made cars woven by hand from hemp by people paid a living wage with fair working conditions, and that the vehicle must have zero environmental impact. Most odd.If you want to boycott Chinese goods, that's really up to you - I dare say you are also boycotting other countries with ethical issues.

It is very hard to avoid anything with Chinese content. Are there any mobile phones that aren’t made in China for example?However, it is very easy to not buy the second most expensive thing you own (after a house) from a Chinese company, and send your money off to the Chinese Communist Party.
