The level of hubris here is pretty high. "No reason"? "No performance benefit"? Porsche is spending billions of dollars to bring a very high performance track-focused sports-sedan to the market. Hundreds of extremely good engineers are getting paid millions of dollars to figure this problem out. I'm sure the transmission is a giant set of engineering tradeoffs (what project isn't), and maybe it won't work out and wil…

I understand your sentiment. I'd like to add the fact that the original Tesla was a two-speed, or perhaps it was the original design for the Model S, but they scrapped it for simplicity IIRC.

There are people on this site and others that truly believe Elon Musk is the smartest engineer on the planet, and by definition his technology is always the best.

if you're looking for the best car on paper, Porsche is probably not for you.

Well in terms of looks, charging network, city driving, autopilot, price and drag racing I'll take the Tesla. So far we've just seen a bunch of hand waving about how Taycan is better on the track... looks like there is a Model S being sent to Nurburgring to lay that to rest.

> charging network

The charging network available to the Taycan is the combination of different CCS charging network providers. They've been doing roaming deals with each other to simplify charging for their users. For example, Electrify America has roaming agreements with EVgo and ChargePoint:

Road trips don't seem to be a problem in the Taycan. 408 miles, one 24 minute stop for charging:

People rarely do a full power 0-60 with a car that can do it under 5 seconds. More likely they go from 30-60 or similar.

I do it quite often, but it really depends on location I think. In more rural locations you'll commonly have a 90 degree turn onto a 60-70mph road. I probably wouldn't if it were 3s 0-60 though.

The tire wear for repeated 3s 0-60 must be enormous.

I'm surprised ZF/Porsche didn't turn this into an eCVT, as an eCVT (a la Prius) has probably the same complexity, but with the added benefit of having more ratios. I suspect it would also reduce shock loads on the transmission as a result of shifting. I wish the article would have gone into this, because I suspect Porsche said no more for marketing reasons rather than technical ones, as CVTs are universally hated in…

CVT transmissions can’t handle the power. They’re also universally hated by everyone except people who merely use a car to get from A to B. A Porsche owner is the polar opposite of someone who would tolerate a CVT.

someone this close minded would likely not be considering electric in the first place (and would probably whine about porches being mostly v6 and not v8/10/12)

There’s almost no chance Tesla is going to get anywhere near the Taycan. There’s been a few professional drivers who’ve given it a shot and breaking 9 minutes has been a challenge. For context, that’s the same lap time as a Mazda MX-5.

There’s almost zero chance Elon is going to find another 1:20 with the existing Model S. Just not going to happen.

Close minded? Huh. You won’t find a CVT in anything but a budget economy vehicle. If you want performance, you don’t want a CVT. If you want to prioritize efficiency over everything else (including reliability), a CVT is fine.

That's ridiculous. The more cars you drive near, the more likely there is to be a collision. I take off from lights to get away from the pack, and I drive away from the packs on the highway. If there's nobody near you, you can't hit them.

Motorcycles do this too, and the drawback is that you are much more likely to run into someone who's just missing the red light in the other direction. And that will be a high-speed differential collision, not anything like contacting the people who are going in the same direction as you.

This is more of a risk in places where red light running is endemic. Sadly here in Auckland is rapidly becoming one of those places.
