Batteries never likely to have a higher energy density than actual gas. Plus gas loses mass as you use it. Sad but true

key point is...”if it weighed nearly the same”, and the 8 speed weighs 40lbs more than the 7 speed, which will make the car slower.

I think it is unclear what the actual weight gain will be (8spd vs 7spd in PDK-S guise). But even if it is 40 lbs, how are you so convinced that a 1.25% weight increase will not be offset by better gearing? I haven't done the math (nor am I capable of doing that math without some help).

In your mind, where is the break-even point in pounds (with adding optimum close gearing with 8 ratios)? With a relatively small displacement NA motor, tight ratio spacing when using near-zero shift times is a big help. It might actually put some daylight between itself and the 6spd Manual this time

Or maybe a lightweight manual box with less internal power loss is an even bigger factor - I simply can't say...

I thought Porsche/automotive writers had indicated in one of the many comments/interviews on the 992 that the new 8 speed did not improve Milage or performance and was built to facilitate an electronic interface for the future.

The gearing selected for the Carrera has never been shared with the GT3, nor can it be, due to vastly different redlines and torque curves. I would expect the GT3 to have optimum use of the 8 forward ratios (though I could be surprised, in a bad way).

If the new GT3 uses the same final drive as the current GT3 (as asserted in a post above), that is even more evidence of a newly revised stack of the individual gears 1st through 8th...

BTW, Porsche has never built a GT car where top speed was not achieved in top gear. It's the usual practice to gear the Carrera so that top speed is achieved in a gear below top gear (top gear just being for reduction of noise, fuel consumption, and emissions).

I would think so, too. It also adds to the list of “improvements” from the 991 cars. They want a lot of improvements.

I can only imagine that a decent spec 992 GT3 is north of $200k, maybe $220k plus ADM. Throw a carbon tub on top of that and we are a long way from $165k loaded.
I think your “spec” changed more than you think it did. The .2 is only $13,000 more expensive than the .1, yet somehow the cost of your .2 would be nearly 200K?

My .1 was 150K, my .2 was 164K. A bump yes, but not a crazy one.

Base price went up 10% and options seem about the same (except for PTS).

it’s actually an $8,200/7.8% increase for the 2S and $8,600/7.7% price increase for the 4S but all of the options are also more expense for 992 which is really the revenue and margin driver.

I thought we were comparing .1 GT3 and .2 GT3?
