Default Camaro like ZR1 coming Auto! ;)

The 2018 GT2 RS is offered only with a customized version of Porsche’s seven-speed, PDK dual-clutch automatic transmission that “enables power to be transferred with uninterrupted traction,” according to Stuttgart.

(The Camaro's Auto doesn't use PTM!? The Camaro came First!)

This car uses electronics all over the place! A civilized 911!

It can, but did not for the 'ring run:

(Andreas) Preuninger also told us that (Lars) Kern set the lap record with both traction and stability control switched all the way off.

BUT, GT race cars have simple TC, and NOT All of this!!!
And the big relatively low tech ZL1 does what?

  1. They aren't turning off the rear engine chassis control!
  2. They aren't turning off the rear engine steering!
  3. They aren't turning off the rear engine lock!
  4. They aren't turning off the edif. (in ZR1!)!
  5. They aren't turning off all that data collection (in ZR1!)!
  6. THIS IS A 911, AND ITS NEVER BEEN RIGHT! IT WAS SUPPOSED TO DISAPPEAR 30 YEARS AGO!
    MANY CAN'T BUY IT - RAW!
The diff. and the auto keeping the RR's (up sloping HP and down sloping TQ) up negates the need for a PTM like the new ZL1. Or was Porsche first?

The Killer Hypo RWD Porsche:

https://jalopnik.com/the-porsche-911...d-t-1796032020

It's not like they are above a little secret sauce! The Miracle on Electronics:

To ensure the best possible traction, the PDK in the 911 GT3 is combined with the Porsche Torque Vectoring Plus (PTV Plus), which incorporates an electronically-controlled rear differential lock with fully variable torque distribution. The system brakes the inside rear wheel in a targeted manner to improve the vehicle’s steering behavior and driving stability. PSM specially tuned for GT sports cars PTV Plus complements Porsche Stability Management (PSM), which optimizes the handling and behavior of the car through various interventions including selective wheel braking. As on the previous model, the stability system is tuned for spirited driving in the new 911 GT3. The PSM can be deactivated in two stages using the ESC OFF and ESC+TC OFF functions. In the first deactivation stage, “ESC OFF”, the potential driving dynamics on race tracks are increased by deactivating the stability control ESC. This allows the driver to deliberately destabilize the rear end of the 911 GT3 in corners. The longitudinal dynamics control functions tuned for sporty driving are retained in this driving mode. In the second deactivation stage, “ESC+TC OFF”, all driving dynamics control systems are deactivated. This gives the driver full control of the vehicle according to his or her preferred racing style.

Interesting though is how we were watching a little ACR (tires & aero) and Camaro (right gear for above of the MAX torque RPMs, and Ediff) success culminating in a Porsche! It looked like it banged off of 5000 RPM a couple of times!? The car probably only saw 700 HP on the last straight after he switched up the boost!

An autonomous chassis: A scripted track fastest segment system with straight line through curve(s) segments. It controls an automatic transmission, and traction, with ultimately no limitations. For instance if you were too fast and off the fast line wide it would equate to being shifted sooner (GT2 RS accelerating RPM's kept mostly above HP (dominant) and TQ curve crossing (GT3 NSM); the trans. worked with that power!?)(Even with you using the paddles!?). Add curve and Vette G-force calculation limits. That segment if faster would be your new fast segment, but, you could reject it.
Virtually(Auto trans. performance!?$) all the technology and capability exists and like the basic MR first in the C5 the new ZL1 auto trackmode so is demonstrating albeit reactively vs more proactively(Smarter), hence, slower!?


The ZR1 needs the tire upgrade too!

It's obviously out of proportion, and ugly-even functionally!

The GT2RS like the huracan performante has active aero. It's a combination of a front splitter that lowers and the rear spoiler has both height and angle adjustments based on speed and/or driving mode. The only way to get an edge on the competition other than hybrid systems is active aero these days. Would love to see a vette with a DRS style rear wing.

ZR1 should break the 7 minute mark, but barely . . . not shatter it like the GT2 RS. Everyone should feel proud when it does, because that's no small feat.
The 991 RSR is a 911 body and mid engine, they've inched it forward year after year since the 930.

While the GT2 RS doesn't use any active aero, it still generates a lot of downforce, helping it maintain high cornering speeds at the 'Ring. At the front, there's a big lip spoiler and an air extraction vent on the trunk lid, and at the rear, there's a big, manually adjustable wing. With the wing in its normal setting, the GT2 RS generates 750 lbs (340 kg) of downforce at its 211-mph top speed, and when it's set to its maximum angle of attack, that figure increases to 992 lbs (450 kg).

oops. I assumed it was using the same system as the turbo s. I've had to focus 99% on corvette's lately.

Default Yep! It's working with ABS too! All the time on curves - TC and Stability!



Porsche Torque Vectoring Plus (PTV Plus)
PTV Plus is specially designed for the new 911 GT2 RS and operates in conjunction with an electronically controlled, fullyvariable rear differential lock.

To actively control the differential lock, a number of driving parameters are considered. The result: increased traction, especially at the limits of dynamic driving performance, better transverse dynamics and significantly improved driving stability during load changes, in bends and when switching lanes. The system also selectively applies brake pressure to the right and or left rear wheel. So brake pressure is applied to the inside rear wheel as soon as the steering kicks in. A greater amount of drive force is distributed to the outside rear wheel, thereby pulling the car into the bend, as it were. Steering is therefore improved and agility increased.

I was wrong about it momentarily being able take the load off the engine to get the RR's up with the diff.. Prescribed Downshifts?!
If you look at the RS VID you see what seems to be unloaded quick as much as 10K to sweet spot jumps in RPM!?

Anyway, Vette ZR1 Stuff!

"HE TURNED EVERYTHING OFF!" If it wasn't so accomplished it would be Scary!

I believe I recall MR and the ZR1 making Porsche look silly a while back!?
