I suspect that will not happen until after the next 8 year run completes. Aside from production volumes being a big challenge for complex carbon fiber reinforced plastic parts, they haven’t even fully gone to aluminum yet, although in fairness high strength steel does offer packaging benefits.

I’d love a 2500 lb 911 or 718, even if the engine was a bit modest.

Have not driven the 2RS specifically, but yes, certainly. Particularly for average drivers, but even for pros. The ability to keep the hammer down in traction limited situations can’t be underestimated. I rode with Walter Röhrl in a 4wd Turbo S and he was able to drive around the chassis adjustability limits 4wd imposes... I’d say even for Cup Car or RSR levels of grip 4wd would be a huge positive. One can also estimate based on the extra weight 4wd cars need to carry when they compete vs 2wd in certain race classes, which is always more than the gear itself.

That said like you I wouldn’t want one.
