I wonder if this is part of why their dual-motor models get better range. I could see it being better for regenerative braking, too.

Not sure on the S or X but my model 3 AWD has less range than RWD. AWD is quicker by 10%.

AWD adds more weight and drive train losses.

From road and track: """At launch, Porsche will offer two versions of the Taycan—the Turbo and Turbo S. The Turbo will carry an MSRP of $153,510 at launch, while the Turbo S will cost $187,610. Both of those numbers are minus destination charge.""" I suppose that leaves room for a non-turbo (lol) Taycan closer to your prices sometime in the future.

What's the turbo doing?

I (lol)ed because "turbo" and "turbo-s" are a naming convention from their conventional cars that is fairly non-sensical on an electric car given that they don't have turbochargers.

Eg. Macan Of course, the two non-turbo Macan models above both turbochargers so the moniker really just means "the fastest model" in Porsche speak.

The combustion non-turbo 911s also have turbochargers, so yes, long time marketing label, not feature description.

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…

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.

Serious question: how is this antisocial behavior? I understand wanting to stick with the flow of traffic when you're part of the pack, but if you're in front of the pack, what's the advantage (to anyone) of hanging back?

1. By accelerating dramatically off the line, you're telling the other cars that they are driving too slowly. 2. Alternatively: you may be sending a signal that you want to drag-race with someone. And nobody likes it when drag-racers start playing on public roads. Keep that stuff off the streets and on the track only. Now sure, if the cars next to me are driving slowly, I'll leave them in the dust. But its not someth…

If you take someone accelerating quickly from a light as a signal that you're driving too slowly, you probably drive too slowly. I don't think its a signal at all - and who really cares if it is?

A 5% efficiency gain might be a big deal when it comes to motor heat. Electric motors tend to be around 85-90% efficient or so, and if you can get the motor from, say, 85% efficient to 90% efficient, that might translate to a one-third reduction in waste heat.

> that might translate to a one-third reduction in waste heat. Is that a big deal, though, compared to battery heat? Or is it in the context of a race scenario?

My understanding is that getting rid of waste heat is one of the main factors that limits how much power you can get out of an electric motor for any length of time. Less heat means you can get up a long steep hill without overheating (or causing the electronics to back off on the motor amperage to avoid damage).

Lots of things have had "turbo" terminology over the years.

Which seems pretty reasonable...large family sedan vs a sports sedan. Besides, when the new Tesla roadster rolls out in 2020/2021, it is game over for everyone else anyway. At a price point of ~$200k, it'll kind of make the Porsche Taycan a joke. Unless you are a Porsche only individual. Which, to their credit, is a fairly sizable market.

Tesla's capex spending is lower than their depreciation, meaning they're not investing enough to maintain their existing production lines. There is no way they will be rolling out any new models any time soon.

Additionally the MS and MX interiors are starting to get a bit dated compared to the ultra-sleek Model 3’s interior - the MS’s interior design is still fundamentally unchanged since 2012. They did upgrade the infotainment system in early 2018 though, but that’s invisible to users who don’t notice smoother framerates.

Leaving all the other cars next to you in the dust is quite antisocial behavior actually. For the most part, I want to accelerate with everyone else when that green light goes off (except for Trucks: I wanna leave Trucks in the dust and get away from them ASAP). The 30mph to 60mph acceleration of off-ramp into freeway cruising speed however, is pretty important. A lot of things are going on when I merge onto a freewa…

> what's the advantage (to anyone) of hanging back?

It might just be me, but driving at night on rural roads is much more pleasant when you’re behind a car that’s travelling at the same speed and route. Having someone follow is much worse, with headlight glare being irritating.
