Welcome to the future. I am an ICE individual but I wonder how I would feel at (say) 14 when in my youth I dreamed of exotic sports cars. I think this would make all the conventional dream cars look old.

How many 2-3 car families run all electric? ...
Daft argument right now. Will be at or near zero.

Come back in a decade and I bet the needle has moved considerably. Come back in 20yrs and it will be the majority.

How many 2-3 car families were there in 1908 versus 2-3 horse families? Its exactly the same type of argument smile
Horses as personal transport, I would say there were close to zero. Only really the very wealthy landed types had personal horses, and many of them probably had motor cars too by that time, the rest being working horses run by farmers, hauliers etc. Most people had no need or expectation of travelling around freely and easily as we do now.

Here we go again... Yet another £2M, 2000 bhp, 2 tonne EV hypercar.

I'm bored already. They are all so unobtainable and pointless from anything other than a technical standpoint.

Make a £50k, 300 bhp, 1.2 tonne EV sportscar and then we can have something to get excited about in the real world.

That's not the point, though. A car having more performance than you can reasonably use all of on the road while also being too wide and heavy for B-roads is not a new thing.



AMG/M/RS cars have exactly the same issue at a lower level, and people still buy them.
But the price is the point. If I had had to pay £113k for the Tuono compared to £7k for an MT07 I wouldn’t have bought the Tuono.

I suspect slow in and fast out will be the best method for the Rimac too. So maybe it‘ll be a better road car as a result?
Apart from arguing for arguments sake what are you trying to say?

You’ve said recently that you aren’t the best rider. Don’t take my word for it. Why not ask others in BB - perhaps Steve Bass - whether the Tuono is heavy and rubbish on the road and how much better the RS125 would be?
I know the Tuono is an amazing bike. Despite it being way heavier than something like an rs125.

Maybe the Rimac is a better road car than something weighing 600 kg less. I haven’t driven it. Have you?

And, by the way, I‘m not sure what my statement about not being the best rider has to do with anything. Not sure why you brought that up?

absolutely insane, the way it played with the sf90 like it was a slow car is hillarious

imo this is a hugely significant car, I can't see how ferrari etc can distinguish themselves if this is the power that's going to be in supercars, a game charger

You would if you were the kind of person who buys £2m toys. Yes, it's pointlessly quick. So are loads of things.

I'd be interested to know what would be quicker around a track or more enjoyable to drive. Cars are so insanely fast these days that if something is a bit slower in a straight line but more enjoyable to drive then they'd still be a market for that.

I've been lucky enough to drive some very quick cars around tracks, cars like the P1 and 918, top league hypercars.

And for a trackday, i'd simply pick a caterham (or perhaps a BAC mono)

Why?

Because the limiting factor on all ultra high performance cars are their tyres, which is broadly why all such cars have such similar lap times, because the tyre is the weakest link so to speak.

With modern chassis tech you can make a heavy car handle, stop, steer and go pretty much as well as a light car, but you can't keep the tyres in one piece for very long. Something like the P1, even on the optional "Track spec" tyres and in race mode, you have 1 lap at max attack before the tyres are finished. One, single lap.

You can get in a caterham (or mono) and literally drive the wheels off the thing all day and probably still have some tyre left!

Watched this yesterday and it's just nuts. The Rimac made the SF90 look like a car from 10 years ago.
Mate Rimac's confidence in it was obvious (what a guy by the way!) and you can see why when Matt Watson ended up toying with the Ferrari after a couple of runs in the Nevera.

With Porsche having a decent stake in Rimac this looks like the way of the future.

Not really bizarre, although I'm not sure where that exact figure comes from. Anything with 2000hp is going to be traction-limited, probably to well beyond 60mph, and the only things in contact with the ground are the tyres. With everyone using pretty much the same tyres, either Michelin or Pirelli, this becomes the limiting factor, no matter how much power or torque you have.

Good looking car inside and out. Performance is likely to leave the driver not concerned about a lack of noise.
Would still go Lotus Evija though.

Well if you can only get 1 lap in a P1 then, considering this weighs a lot more, you might not get a single lap....? I assume you mean a lap of something like the Nurburgring Nordschleife? Performance cars can do a lap of that....

With everyone using pretty much the same tyres, either Michelin or Pirelli, this becomes the limiting factor, no matter how much power or torque you have.
There are tyres that are capable (and are road legal, if barely), but it comes with some caveats; the sizes available dictate a change of wheels, and overall performance i.e. handling and cornering are affected as the side wall of the tyre is designed to do the opposite of something like a PS4S, by squatting and wrinkling up to help widen the footprint of the tyre, and then work like a coiled spring when the tyre's wound up.

At this point though, we're very far away from the 'jack of all trades' that the EV Hypercars are said to be, and so unless someone commits to the path like Dodge did with the Demon, and setting the car up purely to go drag racing, the likes of the Nevera are probably already pushing the 'regular' tyre envelope as much as permissible. Weight transfer onto the back axle becomes quite key also, and for a car designed to corner well, you don't want that weight transfer I expect.

Valid claim. Slicks and 168kg weight gets you down to 1.53s (see https://ethz.ch/en/news-and-events/eth-news/news/2...

But for road cars, it stands to reason that you can't accelerate from 0-60 faster than you can brake from 60-0. You're traction limited in either case, and when braking air resistance is augmenting the force provided by the tyres, whereas when accelerating it's obviously working against it.

The very best road cars stop in just under 27 metres. Handily, 60 mph is approximately 27 metres per second. If you assume a constant rate of deceleration, the average speed over the distance from 60-0 will be half that, or 13.5 metres per second. 27 metres divided by 13.5 metres per seconds is 2 seconds. So especially if you factor in the drag too, it's basically impossible to get from 0-60 in under two seconds on normal road tyres.

Does this now seem less bizarre to you?

You can cheat by including the "foot roll-out" that drag strips take off, caused by their laser beam timing gear, which may get you down to ~1.9ish, but you're then measuring something like 4-60 mph, which is different.
