Know nothing about automobile engineering but somehow this feels like WordPerfect releasing a fantastic version for DOS when Windows was already capturing all the market. Btw they did that. Rest is history.

In Germany, where Porsche is from, sales of EVs are on the decline. The same is true for other countries in Europe as well.

ICE aren't niche, and there isn't strong evidence that they will be. There doesn't seem to be a public Come-to-Jesus moment for electric cars on the horizon. There seems to be solid reasoning behind that reluctance. That is, it will be difficult to displace. If phasing out ICE comes down to regulations only, then the antique interface analogy doesn't fit. >On the other hand of the spectrum, Hyundai Ioniq 5 N can emul…

>need to talk about the vanity attraction of a future all electric Porsche Future? You can buy an all-electric Porsche Taycan since 2019 - and it’s faster than the 911. Sports cars are fully adopting electrification, due to the huge torque numbers and high scalability. M-B and BMW of course, but also Porsche and soon to be Ferrari. It’s not just hybrids used for a boost (as in the decade past): those are full electri…

What's your point? Future or now, my point about vanity remains. I don't see any point in arguing over my use of the word "future" here.

Again, "faster" isn't the most important metric for car enthusiasts. Which is what I described in my post. I know that's disappointing to people who would like it to be in order to claim total justification for electric motors.

To say that "sports cars are fully adopting electrification" seems to want to imply that sports cars are moving mostly to full electrification. This isn't remotely true. Their customer base wouldn't stand for it.

Think this is short term. Again no expert just based on what I see. Solid batteries give it few years then the maths will be very different

In August. After a 38% tariff.

When Porsche says efficiency they mean making more power, not using less fuel. Porsche has a long track record of adopting efficiency tech and using them to make fast cars that still use a ton of fuel.

What’s the difference between getting more power out of a given quantity of fuel, versus using less fuel to achieve a given power output?

My assumption is there is a context difference.

Efficiency in fuel/mile. Efficiency in Power output/liter of displacement.

But that is just my assumption.

You can have a relatively small engine and force a ton of air/fuel into it under boost and get tons of HP but it tends to lose the ability to maintain fuel economy. Tune it for fuel economy and it tends to lose power. It is very difficult to have both in the same package for many reasons. Adding mods like discussed in the article start to allow for the overlap to be wider.

Your understanding is very out of date. All electric sports cars have been a thing for a while, even at the supercar level. Car enthusiasts have in fact embraced electrics. Go on youtube and look up drag race comparison races and a Model S Plaid is very frequently the one people want to beat. Double clutched automatics have taken over h pattern manuals.

My understanding isn't out of date whatsoever. Your understanding is wishcasting.

You citing the appearance of the Model S Plaid at "youtube drag races" reflects more of your lack of understanding than my own.

The double clutch vs manual debate isn't relevant to the one under discussion. Its an interface argument that is more niched than ICE vs electric, is specialized to each particular car, and each particular use and driving preference.

I actually miss DOS. I could focus on one task for hours without being distracted by other apps trying to get my attention. There was something raw and engaging about being a few layers closer to the hardware without all the bloat. And, while I'd never go back to mechanical hard drives, you could hear the computer 'thinking'. It was more visceral. I think it's a great analogy. It's all the little quirks and flaws tha…

Interesting perspective from someone that owns both. I only know ICE unless as passenger.

Yes manual steering and gearbox are fun. The response is linear predictable.

But if I were a kid entering college I'll be scared to choose automotive engineering as it's mostly likely to be wasted knowledge..

I'm sure one day we will look back and laugh about how we used to install actual mobile power plants in our cars. But as of today, they are still objectively better on many criteria.

What makes you so sure? We don't look back and laugh at people using horses for transportation. We understand that's what they had at the time.
