Preuninger says more than a second faster than the previous model to 200 kph. The 997.2 gt3 did 12.3 so.. 11.3 or less!?
Preuninger "sure that we are within the gt3 rs 4.0 lap times" (Nurburgring)

Weird. The EXACT OPPOSITE of every other paddle shift car out there. Ugh.
+1
Isn't he the same maketing shill who also promised how wonderful the faux CL's are?

Thanks Guy, for the post; that was great! Curb weight is confusing to me. DIN standards include all fluids plus a full tank of fuel, but sometimes dry weights are quoted so it's hard to make a comparison. Also, many Euro manufacturers quote to the new ECE standard which includes a 75KG driver. Given the 991 GT3 weight savings in the engine, chassis, suspension, etc. quoted in the press release I just wonder if the RS3.8 weight you mention included a full tank and was an apples to apples comparison. 475HP should help make up the diff in any event!
Anyway, really enjoyed getting all of that info. Thanks again.

The gearshift lever follows proper sequential logic (back to upshift/forward to downshift) but the left paddle upshift/right paddle downshift they mention is different, certainly from what it is now. I wonder if that's a typo?

The rear steer is a brushless electric motor (basically a "jack screw") on a rod that can move a total of 30 mm. That's over an inch of movement, which effectively "shortens" the wheelbase at low speeds (counter-steering, like a Honda Prelude from the late 80's ... famous for bumping the rump into walls and posts as people tried to maneuver, not realizing the car would arc outside it's turning circle.) and will negate the phase shift of high speed "lane change" maneuvers. I'm not liking any of that in terms of driving a 911, but it will make for a devilishly fast and stable car capable of rapid direction change, so it should be marvelously responsive to steering wheel input. At least, no PDCC. Swings and roundabouts, I guess.

Curb weight goes above a 991 Carrera because of rear steering, larger fuel tank and mandatory PDK. The 991 GT3 is "only" 30Kg lighter than the 997.2 GT3 because of those factors and the Carrera GT seat is no longer road legal (no thorax side airbag) so the car has to be weighed with the sport seat.

UK press release. They drive on wrong side of the road and sit on wrong side of the car. Let's give Porsche the benefit of the doubt that they reverse it for normal parts of the world.

Yup. He had one shot for a BS moment and he played it that day.
I will definetely give him another shot though. I like the guy.
Besides, this is more important.
Remember, here in Rennlist (Doug's the pioneer) we figured out first how to ditch the CLs. Not sure we can pull a simillar stunt on the steering if it sucks (like the 991 one does f.e.)

"At speeds of up to 31 mph (50 km/h), the system steers the rear wheels into the opposite direction of the front wheels. The 911 GT3 enters the curve faster, which permits more dynamic cornering. The ‘virtual shortening’ of the wheelbase by around 150 millimetres also results in significant improvements in agility and everyday usability; the turning radius is reduced, and manoeuvring and parking become much easier.
At speeds above 50 mph (80 km/h), the system steers the rear wheels parallel to the front wheels. This results in a geometric virtual wheel extension of about 500 millimetres, thereby increasing stability particularly at high speeds. Simultaneously, the side force on the rear axle triggered by the steering input of the driver is built up much faster than with a non-steered rear axle, which leads to a more spontaneous and harmonious initiation of the change in direction."
Should make for some interestinng driving dynamics in corners where you transition through 50mph.

Hopefully a much better PCCB construction.
I have 396 Movits and they're unstoppable ... wait ... no ... um ... unbreakable ... aagh ... they're "good enough"?
410 seems preposterously oversized, and they're thicker, too, but this is an age of "nothing exceeds like excess" so here we go. If they make the PCCBs to last and they provide a track pad compound, I'll call it good.
