This picture, with middle-aged men in blue and grey suits around a wildly overpriced, look-at-me EV, turns me off. It makes me yearn for a Tesla even more than before.
wtf !

I’m sure this has been mentioned already but if this Evija can do 0-186 in 9 seconds are we starting to get to levels of acceleration that are actually uncomfortable to experience?
I’d certainly love to try it- from the drivers seat- but in the passenger seat I’m not so sure
0.95g average acceleration for 9 seconds, shouldn't be anything painful in that especially as your body and head is supported by the seat. I rather enjoy the sensation of 1g acceleration. I’d certainly love to try it- from the drivers seat- but in the passenger seat I’m not so sure
Lateral and deceleration at these high levels gets tiring though, especially as a passenger.

i'm *guessing* the ballistic mode is 5 - 80mph and then eases, of feeling of acceleration eases. I’d certainly love to try it- from the drivers seat- but in the passenger seat I’m not so sure
a airplane doesn't seem that fast either, yet once it's at 60mph (relatively slow to do so) it starts to take off, so to speak, but doesn't feel like it.
physicists will provide the maths..
Having all this power sounds amazing but it’ll be limited by tyres and the odd tree on the corner that you wont make so largely pointless in the real world.
Nevertheless, I do love the thing for all it’s excessiveness and beautiful is an understatement, so much a product of a company that always seems to design gorgeous cars.

I recently went to a theme park in California (Six Flags Magic Mountain).
The "Superman" ride there does 0-100 in 7 secs or so, with a peak acceleration of 4.5g, 6 seconds of weightlessness and all over in less than 30 seconds.
It cost a few dollars for the day, much better value for money than this Lotus

The thing with passenger jets is that they just keep relentlessly accelerating down the runway. They've only got to get to 150 or so and they have a long way in which to do it. Take offs from short runways like Funchal are interesting...

Interesting. So at what point do we think (current) tyre technology can cope? If this Evija could do let’s say 0-186 in 8 seconds, or 7 seconds, what is the mathematics on where the tyres wouldn’t cooperate anymore?
186 in 9 seconds is averaging 0.93g. A Tesla Model S averages 1.18g from 0-60. I wouldn't like to guess what the acceleration profile of this thing will be, because it's got massive power, a massive power to weight ratio, and it's also likely to have significant aero which will increase with speed. It's also going to have drag, but because the aero is active, who knows how much.
Sticky tyres will pull in excess of 1.2g, but once you add downforce to that, you multiply it. If you had enough power and grip to pull 1.2g to 186, you'd do it in ~ 7 seconds.
