Wouldn't manual alone save almost 100 .lbs over PDK? RS 21" wheels are heavy, so that helps. I'm a bit more optimistic than 100 .lbs, but not expecting anything earth shattering.

I think it's 64lb diff for the tans missions but will depend on if they keep Electronic diff and RWS. if they did tech both could get To 150lbft with skinny wheels. RS official figures have plastic Windows, us spec cars probably same weight as GT3

given the spirit of the car, I'd expect they would forgo electronic diff, RWS, maybe even PTV and PASM. Losing all of those electronics would make for a more analog car and lighter one at that.

Plus I expect that the lightweight battery and ceramic brakes might be standard on the R, for further weight loss. Price isn't an issue for this car.

This makes lots of sense but could be much too logical

Battery, pccb, carbon panels and interior door cards and seats, smaller wheels, de contented interior, no rws.. If you can take 200 lb off of an RS, all 600 or so chosen ones will be excited. DISCLAIMER: All the above is pure speculation on my part, I blew my load on actual info already.

we can look at the comparison between a 997 GT3 mk2 and a 997 gt3 RS 4.0 to get a good (and better) proxy of the weight benefits provided by light materials since the 2 cars shared the same body (just wider rear in RS).

As we know 997 4.0 and 991 RS adopted the same lightweight package (carbon front hood, fenders, rear hood and wing plus lexan windows, titanium silencer etc etc) compared to standard version.

In the 997 series this lightweight package provided 35kg weight saving (1395 vs 1360 kilos), without considering the extra weight in RS of bigger wheels (1 inch rear, half inch front), bigger tires (front and rear), bigger engine displacement with more cooling surface needed etc, rear wide body, different suspensions in the rear with additional springs as in GT2 RS, plus other stuff I don’t remember…hence I assume “coeteris paribus” the weight saving is 45kg.

Let’s take a 991 gt3 (1420 kg), with RS light materials should be 1375kg, with 6 speed MT instead of 7 speed PDK we should arrive to 1345kg, let’s take off big rear wing and front spoiler, some tires as assumed, some stuff inside with lighter door panels etc, something lighter outside (magnesium roof which in 997 was not used), a set of magnesium wheels (Manthey’s ones weight 14kg less than standard ones).

Imho not so difficult for Porsche to make a car in the (very) low 1300kg…

From a couple of comments I've picked up, as well as the generally accepted low numbers, I think that Porsche's strategy is simply to provide a bonus for original 918 purchasers who still own the car, and want one. This means that next time they launch a 'halo' model, it will be incentivised in advance, rather than being a hard sell. It also does reward the people who put the cash up. Normal business practice.

All 918 owners have been invited (to pay...) to go to Geneva for an advance viewing, so surely they must be offered a car when they get there. Would be a bit rude otherwise!

That will cause uproar, no doubt, but if they clearly say it's a specific 'reward' for 918 owners, then at least it's clear cut and done. Anyway, let's say it's much more expensive than an RS, if it wasn't for the expected 'investment premium', how many MT could they sell at that price?

This way, Porsche get the cream instead of the after sales market. It's also a halo car in its own way for the relaunch of MT in GT3.2 etc.

they are giving very little info (none official), but I expect it to outperform expectations in terms of weight, driveability, performance, Internet arguments etc

According to weissach you can't have extreme underbody aero on a rear engined boxer engined car . The engine is too lowland something about how flat the floor is [sorry I can't remember exactly] etc , that's why it's never really been available even on rs models

bronson7

I guess it makes some sense. I've never really looked underneath the body of a Ferrari to see what's so magical under there, but it surely does work.

I thought I had one on order until my SA called me yesterday and said that they are not getting any. Only the largest dealerships might get one. Oh well.... It was a long shot anyway. Back to my GT4

Yes, an effective rear diffuser needs to start in front of the rear wheels and accelerate the air gathered from under the floor of the car to induce a low pressure area, which is what creates downforce. The flat six in the rear of the car occupies the same area where you need to place the upward-sweeping, flat, fenced "roof" of the diffuser that is channeling the air from the flat floor in front of it. There is just too much hardware in the rear of the 911 to allow the long, gentle upsweep the floor needs to be effective.




A mid-engine arrangement allows far more flexibility for designing an effective diffuser into the underbody of the car.

Once I put my fat *** in either car, weight reduction becomes a moot point.

If they loose all the electronics, Porsche is going to get sued by Paul Walker's daughter

exactly the problem, why is it that they dont understand that we are the people that build the rep that causes ***** head people to buy fat cars, and instead of rewarding us with cars we want they trickle them out like constipated stools and we know have to demean ourselves and beg for allocations
