About the extra weight on the 991 GT3, I find surprising that Porsche is not offering the light Li-ion battery as an option,

Is there a problem or another good reason explaining that the Li-ion battery is not proposed right away on the 991 GT3?

Any thoughts about it?  Smiley

They explained it in the video with the engineer actually. They HAD to fit the bigger/heavier battery for that rear axle steering system. He says that they ran both the standard car with lighter battery and no real wheel steering head to head with one with heavier battery and the steering and they opted for the latter so the performance benefits outweight the weight loses... I think that is clever because competition is tighter and tighter these days.

At the end of the day, track figure and acceleration figures are less and less important because we are soon at the very physical limits. That is to say, Porsche is shifting gears with the new GT3 in that they want to make it quicker using new technologies (motor mounts, smart PDK, rear wheel steering etc etc..) This is certainly the way to go. Porsche also knows why the GT3 is so special so rest assured they are well aware that they needed to keep the raw and emotional aspects of the drive.

Afterall it's not about pure acceleration anymore... want that just get a 730HP VW Golf and be done with it

0-100 takes 3.1 
0- 200 takes 9.6

Bottom line, the new GT3 is as fast as the last GT3 RS and retains all the emotional driving aspects.
