Earlier quoted context omitted.

Acceleration is the one performance metric that drivers push daily, whether it's merging on the highway, passing, or just a thrill from the light. It is a bit disingenuous to say that it's "easy to achieve" given how it has long been the metric of supercars.

Sure, but not 0-60 acceleration. The joy of driving a Porsche is that you can kick donw th pedal at 130 km/h and still feel the force of acceleration pushing your body into the seat.

And the knowledge that the brakes will work well if you have to slow down.

To get good acceleration you just need a big engine, traction and not much else. 0-60 is not even that meaningful for real world use of acceleration. 30-70 would be much more useful there.

This sort of reductionism can be used for anything. To get good handling, you just need good traction and a low center of gravity. To get good top speeds you just need good top speed. To go to Mars you just need a big rocket.

Traditionally obtaining good acceleration has been incredibly difficult. Larger engines yield a heavier vehicle in a vicious cycle. Makers like Lamborghini would reduce their cars to just shells, use esoteric materials if it could shed tiny amounts of weight, and then would spend enormous engineering trying to obtain more power from smaller engines (not bigger engines, more powerful, lighter engines). To casually dismiss this is just entirely untrue.

Tesla made a big deal about acceleration because it comes essentially for free with electric engines that have incredible low end torque curves. They made a big, 5000lb, full featured, 5-seat sedan and they still could give it acceleration that blew away what million dollar supercars had been fighting to do for decades. And now we're all tut-tutting that Porsche might possibly make something that's kind of similarly capable in a car that will likely cost much more and seat two. Great.

Handling is much more complex than traction and low center of gravity. The car needs to be predictable at different speeds, under braking and a mix of a lot of other conditions. That's a much more difficult thing to get right than going straight.

It has a two-speed transmission, which should help with high-speed performance. https://insideevs.com/news/343827/porsche-taycan-2-speed-rea... But one of the advantages of an electric car for me is the possibility of no (variable) transmission. I don't want clutches that are constantly wearing down as I drive. For me this is not about money or maintenance headaches, but about elegance.

Given that a standard ICE vehicle clutch will usually make over 150k miles before needing replacement, I can't see any reason to think that this will be 'inelegant' - it would appear to boost performance nearly everywhere, and they will not be 'constantly wearing down as [you] drive' - they'll be electronically controlled as part of the transmission and optimally maintained as a result. While I agree the simplicity o…

Wear should never be an issue considering how (relatively) rarely the car would need to shift. It will be used at higher speeds so it won't shift that often. Chances you swing between high and low speed (over/under 100+Km/h probably) that often are small.

There are efficiency and performance advantages to having a multi speed gearbox for an EV. So far about 5-20% improved efficiency for 2 to 4 speed gearboxes. ZF insists EVs might end up using 4-speed gearboxes eventually but I can't help think they're biased in proposing this.

I got as far as $130,000. Edit: £

Well, there are new models coming that start at £65k, which while still really expensive is at least in line with every other premium electric car out there(Mercedes EQC, Audi E-Tron, Jaguar i-Pace all start at around £65k)

Earlier quoted context omitted.

you only need clutches when you're stopped - to engage an moving/idling motor to stationary drive wheels. Electric cars don't need clutches because their motors stop too

Probably the car will switch between gears while in motion. It seems to me that it would be difficult to do that smoothly without a clutch.

It is only important to carefully match the revs when switchen gears. Electric cars with electronic control can be easily programmed to do so.

Glad to see competition finally coming around. That said I still wonder if they're holding back here to not cannibalize other lines. The 0-60 in the 3.5s range is over a full second off Tesla's best and for a performance brand seems like you want to be more in line with Tesla.

If you try to drive a Tesla Model S like a performance car it just overheats: https://www.thedrive.com/news/5207/this-video-reminds-us-tha... https://jalopnik.com/heres-what-a-tesla-model-s-can-do-aroun... Here's a Model S losing to a Nissan Leaf over 14 laps: https://insideevs.com/news/359903/video-nissan-leaf-beats-te... Porsche doesn't want to be in line with that.

That is the old model S being discussed there. The “Raven” P100D has an updated battery pack and motor.

Does it really matter when 80% of these will be stuck in bumper to bumper traffic on 280 near Sand Hill Road?
