+44 lbs, or roughly a 10% increase for a 5% increase in power output.

Well said

Turbo is less reliable too but only on mid term so no warranty issues for VW

or in other words let's say in 10 years of usage by the owners
is more
probable to spend (a lot) for a turbo part replacement
while for manufacters is less probable to have during warranty issues vs a NA Engine

combine Carrera 2S (turbo) is more expensive as a new car
and cost less to PAG to squeze let's say 500hp from a turbo than a NA (exotic metallurgy not needed in a Turbo)

doping here.. you go faster at the beginning but the bill is huge

Wake up Pag where is the
1) electric Turbo?
2) seamless gearbox?

higher and higher pricelist (profit but no contents) but evolution ???

It has already come quite far, and many automakers envision batteries supplementing their future high performance cars. Or do you think Porsche, Ferrari, and McLaren collaborated on their hypercars?
No, I don't believe they collaborated at all. In fact I find it quite interesting (and fully understand) why they all went in the direction they did. Unless you were asking a somewhat rhetorical question.

I just don't think batteries will ever be able to offer the energy density of gasoline, but I will probably be proven wrong someday. Technology marches on as they say...

Man I wish Porsche was reading this: If I had my choice for a future powerplant in a hypercar; say, the replacement for the 918. I would choose a NA engine > NA/Hybrid > Turbo > full Electric any day.

For complexity & reliability & cost of ownership overall - except for the full electric, which I could see as being very reliable, for a daily driver that is.

Note to Porsche: How 'bout you take some of them internals out of the GT3RS's engine (pistons/rods) and develop a NA Flat 12 - 8.0 Liter - take some block design cues from the 918's V8. Or stick that in the "FeFi".

What kind of numbers would that kind of engine make? I'll pay the fuel/CO2 penalty. Whatever it is. 'Cause a car that an engine like that is powering, should be special & expensive, and relegated to track duty and/or weekend drives.

Porsche has been doing turbo cars for a long time. Reliability is very strong. My turbo is 12 years old with my only issues to date are a window regulator, new battery and alternator. Absolutely zero issues with the motor. The most common issues are boost leaks - typically difficult to resolve but not expensive part wise.

You own a 996TT with a Mezger race engine,that's why! Let's see if the new engines come even close,or the old saying " they don't make'em like they used to " proves to be true.

It was a rhetorical question.

As for a 12 cylinder engine, I'd wager that we will never again see a 12 cylinder engine in a new car that costs less than $500K - top of the line Ferrari and Lamborghini series models and the once a decade Ferrari hypercars. All will be hybrid. The S Class/7 Series V12s are probably endangered and gone any day now.

The turbo Mezger engine was refined over decades of use; the new turbo engine is entirely unproven in comparison, and much cheaper to build...

Aston will do it for less than $500K. It won't perform anywhere near a Lamborghini or Ferrari, but it will be a 12 cylinder nonetheless.

This thread is interesting and it makes me think about the new Ford GT which is using a 3.5l turbo V6 that will apparently make over 600hp with around 500 lb-ft of torque.

Since when will AMG be making a bespoke V12 engine for Aston Martin? Turbo V8s going forward

They won't even make one for Horatio Pagani.

This is going to be like the 40-60s.....hey, here is a flying battleship, to SR71 to a moon landing. In 5 -10 years, electric will change everything. It is a superior way to deliver power in a controlled way - industrial robot precision. The big challenge is obviously heat and energy source - but solvable in a matter of single digit years. Turbos will be seen as the dark ages to enthusiast of 2020, and people will line up to buy Mezgers to wax nostalgically.

All they're talking about what Porsche will be producing in January. The factory cutover of the base 991.1 to the 991.2 is then. They'll still be producing the current 991.1 GT3, GT3 RS and TT/TTS.

It's even confirming later on that they're keeping quiet about the 991.2 GT3:
"But the way in the future more than the next two or three years concerning the GT models is not yet decided."

Of course it's decided, but not publicly announced...

Or will it be like World Rally in the 80s? Improving technology brings exponentially faster cars, until suddenly it becomes clear that they are simply unusable... And we go back to driving cars designed for the roads we use them on?

You mean it's like electric, self-driving cars?

The press keep confusing us! Interpretation is different so too the language barriers perhaps? I dont think Porsche motorsport are open about there ideas even to Porschr themselves. Different department different regulations etc etc.
