992 TTS
So I have seen the various videos on YouTube with respect to the new 992 turbo S. Aside from the increase in power up to perhaps 650 hp, what other innovations will the turbo introduce? Usually the turbo premieres some type of advanced technology and it seems almost all of the new technology used today is already been trickled down to the Carrera models. Any thoughts?

Maybe some kind of hybrid drive like the 918? Some kind of KERS system? That’s obviously just a guess, but you have to imagine that it’s coming sometime soon....

WET MODE of course. Because everybody needs that. Right? I'm wondering if it will be updated features to the turbocharging of the engine. Some change of the VTG, etc. Who knows, it could be a change to displacement.

Having owned a 2001 997 Turbo with 420 HP and a 2003 997 Turbo with the Larger HP X50 package Turbos making
450 HP, demonstrated to me the huge increase in Turbo lag with larger Turbos. With larger inertial masses to rotate,
the X50 package surprisingly was a less satisfying car to drive in traffic. While I love driving my 991 TTS, the throttle
response from idle to 2,000 RPM is rather anemic and makes the car feel much less responsive in Traffic.
On the Track where the Engine is maintained at much higher RPM levels, this is far less of a problem.
Driving my friend's Tesla's, the immediacy of throttle response and the faster spool-up time of electric motors is far better
than any Turbo and adds a whole new dimension and increased fun to driving which convinces me that the new 992 Turbo
will be a hybrid car adding the instant response of electric motors to supplement Throttle inputs.

So some type of electric motor to assist the car's acceleration until the turbos kick in? That will add considerable weight. I wish the would use a carbon fiber shell some how. Of course that will push the price way up into 720s territory. I mean the BMW I8 which costs much less is carbon fiber. Although I think they lose money on each car.

4.0TT, and yeah Im betting it gets some sort of hybrid setup with it. This car is already heavy, not sure that will change the dynamics much...so would be a good candidate for a major horsepower cruiser GT rocket.

a hybrid would definitely increase the torque substantially and if they could get it around 700 pound feet of torque, it would be a bullet..........0-60 in 2 seconds.......even with the weight............don't know where you would use that speed except the track....the SL 65 has 738 pound feet of torque and weighs about 1,000 pound more than a TTS and it is a rocket, especially from 2000 rpm on........

Even if the Hybrid 992 Turbo weighs more than the present 991, my guess is the large low RPM Torque increase will make it respond much faster and feel much lighter.

The 991.2 antilag system (S+ only) is really pretty slick. I suspect the 992.1 will refine and improve it, add ~20-30hp, and bring most of the improvements and changes of the 992 to the 991.2. I expect a hybrid would wait until the 992.2. It will be interesting to see the hybrid philosophy they choose. For instance, an electric motor up front could entirely replace the 4wd portion of the present transaxle assembly, and if the battery is kept small the net weight penalty can be kept down.
Of course, if the Taycan is too quick perhaps the development schedule will pleasantly surprise all of us.
I’d settle for all aluminum!
My little Alfa 4C is also a carbon chassis car. The biggest problem there isn’t the cost so much as the manufacturing throughput. It’s still a rather manual process to lay up carbon in most circumstances, so once you get to 10k+ complex parts per year it gets really hard. Current higher volume processes like Lamborghini’s “forged carbon” make compromises that yield similar material properties to high end aluminum alloys - a lot less than the high end carbon composites. A breakthrough in manufacturing process technology would be huge.
Really the biggest issue with the turbo models is they aren’t exciting to drive at anywhere near legal speeds. The weight and AWD system do play a big role in that, and in fairness a lot of the compromises that make them such great daily drivers cause that as a result.

True but you can say that about a lot of cars now, including the 991 Turbo/S and GT3/RS cars. I have a GT3 and find myself driving other cars more often for this reason. Same when I had my TTS. They say there is no such thing as too much power...but for engaging road driving, I disagree.
