Absolutely Day to day EVs are easier I agree. But 200 miles is what you will get on a good day if you drive slow and is only 100 miles away assuming you need to get back.

But I would guess that most people that buy this sort thing might want to take it down to Courcheval skiing and the Canne in the summer both would be bloody difficult in this. All I’m saying is 65k+ is a lot for something so limited.

90kwh should get 250 plus pretty easy? 270 is 300wh/mile?

A friend has the X with ludicrous speed. We raced my Cayenne GTS against his car. (not on English roads I hasten to add).

I’m not sure the Cayenne is a competitor as the X has 7 seats. But, I considered both and ended up with the Cayenne and my other in law gets to drive herself.

Anyway, back to the race. The X had no issue getting a car length ahead and keeping the advantage. We were expecting this though. I was a little surprised it didn’t totally destroy me.

The amusing thing was my friend said that due to my car sounding so good it was the perfect mix of his speed and my soundtrack.
What sort of speed was it at? I find my Tesla tails off quite a lot at 100 that is where an ICE starts to really come into its own.
We went up to 100 when I thought he backed off so I did as well.

The 200 mike limitation isn’t a concern for me because I would use the EV for commuting and keep my Porsche for family duty. Having said that, the X and S don’t make a huge amount of sense. A 3 may do though. My manager has one on order so will take a look at that when it arrives.
One final X point that is quite topical. My friend says they are scary in snow. 4 wheel drive to go but it’s the slowing part that’s an issue

Well in the temps at the moment I am getting 450 wh/m. In the summer I get around 330 wh/m most of the year around 350wh/m.

Those ranges are theoretical as well because you rarely charge to 100% because it takes to long and you don’t go down to 0% You usually allow 15-20% spare as a just in case so generally you end up with 70% usable safely. Range also plummets if you decide you want to use much of that performance like say 90mph cruising You can forget decent range.

I may sound like a massive anti EV I’m not just long journeys and speed I have personally found them frustrating with the demands that I have from a car. If you don’t travel all that much and you fly on all your holidies fair enough Tesla are great and I’m sure this Jag will be too. I just expect a lot from a car especially for this kind of money.

Mine has been as good as anything else I have driven in the snow (lived in Switzerland so quite a lot) about the same as my Audi’s or Range Rovers on summer tyres.

It'd be interesting to see what these are like in the snow. Is the way the power gets delivered an issue I wonder. And I'd be interested to know how they behave slowing down too.

On the i-Pace (which should really be called the E-Pace, let's be honest), it'd be easy to become besotted with it's looks, uniqueness and tech and rush out and order one.

For low-medium localish mileage, charging and range wouldn't be an issue as you'd always be within the batteries return radius. It's when you want to go on holiday twice a year, or for weekend breaks that the whole thing falls down. Unless you can buy portable charging gear that you can plug into your unsuspecting holiday cottage owners wall socket - can you?

I'd love one, but my 3 year old diesel navara cost 10k and does 500 miles to a tank.

When they can compete with that then I'll get one

How often do you do 500 miles in one go? In a pickup?

I suspect legislation will be what pushes the majority toward this technology, but by the time that happens your criteria will probably have been exceeded anyway.

Although so much of this is bleeding edge stuff, the two centrally installed motors with half shafts and double CV boots all round seem a little bit "legacy" to me. I understand everything is costed and there are margins to consider, but wouldn't a dedicated monitor at each wheel be a better solution? How do Tesla/Fisker/Nissan/Renault do it?




The packaging is to die for though! ICE will always be my passion but EV's can't come soon enough for the M-F slog to work. No fuel tank, prop shift, transmission tunnel, final drive, cooling system. OEM's have invested billions, maybe trillions into optimising the ICE formula for the past hundred years, and I think it's exciting to find out what can be done with electrification in the next hundred.

The problem is motors, whilst much lighter than internal combustion engines, are still pretty heavy so you really need them attached to the sprung part of the car. Sticking them out at the ends of the suspension links would be a horrible thing to try to tune the suspension for.

I'm not aware of any production EVs using hub motors - Tesla and Nissan certainly do not. Even if you are going with a motor per wheel, you still want to use half-shafts to keep most of the weight sprung.

I believe the motors are permanent magnet motors which is different to the ones Tesla use and are potentially more efficient in some cases. I suspect in wheel motors may well be a thing in future, but only if the weight of the drive units can be drastically reduced. Whilst the motors are relatively small, they tend to be incredibly dense. Adding 50-60kg of unsprung mass to your wheel and hub assembly would be fairly disastrous from a ride and handling perspective.

The fuel tank is the batteries and EV's do have cooling systems. The skateboard architecture the 'luxury' manufacturers seem to go for appears to dictate SUV vehicles and not the greatest focus on weight distribution.

Heavy battery between the axles, closest to the ground, what would be greater focus on weight distribution?

If Tesla tested the Jag (if it were available to test) against the P100 version equipped with stupid acceleration whatsit the jag wouldn't see which way it went.
Its a bit like Honda testing the CTR against a bog standard 1.6 focus and making a big deal out of it winning a drag race.
If you're not comparing like for like its pointless.

So why are you comparing a £60k Jag against a £130k Tesla? And one with 600bhp against a Jag with 400bhp? Sounds a pretty pointless statement to be honest.

Yep this really is the end of the discussion. Tesla love an arbitrary acceleration test and it's rightful competitor has just trumped them.

Yeah it beat a similar price Tesla model. Because it's smaller and lighter.

How good is it at seating 7? Stupid test really.

Tesla has a lot of fanboys eh

Tesla are the absolute kings of the pointless 0-60 dash publicity event against random other vehicles proving them to be masters of the universe, as soon as they loose one it’s suddenly a silly and invalid comparison

Everyone knew that as soon as the big boys got into the game they were going to start loosing and this is what that looks like
