Sounds very plausible!

First weight number I've heard. Impressive and relatively easy to get it under 3,000lb if true.

3,058 Lbs (1,390 Kg) is probably a dry weight. But hopefully not.

None of the rest of the info is new. 500hp? Not 515, 520, 530? RWS? Lightweight battery?

This is the second interview where Herr Hatz suggests a NEW engine for the RS:

http://www.pistonheads.com/news/defa...?storyId=31485

"... it will be the first outing for a new engine. This sticks with natural aspiration..."

"Hatz said this RS’s engine is an “intermediate step” on the way to the launch of all-new engines for lesser 911s later this year."

Perhaps they had no choice but to go with the new Euro 6 block due to time constraints for the September deadline?

What could be an intermediate step between a 3.8 9A1 GT3 motor and future "all turbo flat six except GT3"? All new outing = just 4.0? Or more to it? A big drop over the GT3 in Ring lap times is going to need more than down force and 200cc?

1390KG sounds good.

Yeah, intermediate step doesn't make sense. Not surprising on the 911 switch to Turbos, but still very tough to see them keeping a different engine for the GT3 only.

EDIT: More exciting news is that PTS is back on the config website for 911s - maybe there is hope for the RS yet.

I have heard that the real "Turbo" and GT2 (if one) would also share the GT3/RS dry sump engine (but add turbocharging), so that the Carrera and Turbo would not share the same motor (just like in the old days of the M96/M97 Carrera motors while the Turbo and GT3 used Mezger).

The eagerly anticipated Porsche 911 GT3 RS will get a brand-new, naturally aspirated six-cylinder engine according to company bosses, with the unit eventually working its way into other models within the wider Porsche range
"Hatz said this RS’s engine is an “intermediate step” on the way to the launch of all-new engines for lesser 911s later this year."
One possible interpretation for the 2 quotes - they are dumping 9A1 altogether. And coming up with a new modular engine architecture. And RS will debut it in NA form. And next, all the different versions of the new architecture - turbo, hybrid, 4 cylinder etc will percolate through the 911/Boxster/Cayman line up.

Just speculation on my part, I think, the chance are something is being lost in translation and he is just talking about 4L version of GT3 unit.

Top Gear is also now quoting Hatz saying something to same effect:

He had earlier explained that the new 911 GT3 RS, which will be launched in March at the Geneva show, features an all-new very powerful naturally aspirated engine. A version of that engine, with turbos but less power, strangely, will be what's in the facelifted 911s in 2016.

Yes, very curious since "intermediate step" isn't a term PAG would typically use to describe the RS, at least performance wise. I wonder if this might be in reference to fuel efficiency measures (and compliance with euro6 etc standards), since any reference to the 992 generation will be remarkable in the history of the 911 for its transition to FI and thus ultimately towards improved fuel economy. Perhaps the new RS is able to deliver greater performance and output more efficiently than the 997 generation and even the 991 GT3? That could be believable and might explain how the RS could be moving in the direction that the radical 992 departure will take. Perhaps this also signals that the 992 generation of GT cars will be "fully" fuel efficient and no longer NA???

As for PTS, this would not be typical for a new release. However, the RS should be a MY2016 release (so the moratorium on PTS for MY2015 is moot), and maybe the rumoured shake up of the PTS process will now allow for PTS even early on in a product cycle, rather than through an unpredictable window late in the cycle. Hopefully, they've been listening to customers and recognize the immense interest in this option, particularly amongst the most die-hard customers who tend to be early adopters. Plus, given how many owners will be 918 customers, PAG may be bending a few rules for their VIP clientele.

What amazes me is that none of the two interviews had a follow up question to mr Hatz about the "new" engine! New 4.0 or new from 1gt3? Confused!

1390 kg is good but it seems hard to reach 7.05-7.10 ring times?

I assume they weren't real interviews, but rather send your questions in and we'll select the ones we want to respond to.

Maybe it is a new engine all together, perhaps the 9A2, which also lines up with the rumored 992 model name rather than 991.2. Not sure I want to be the beta tester for a new engine given the GT3 issues.

agreed. Im confused too. I doubt those are actual targets given its closeness to the 918's 6:57 time. I think they will strive for something like 7:15 or 10sec quicker than the standard GT3.

Unless they always planned years back to make a separate engine for the RS from the GT3, there is no way they could have developed it that fast. If they decided to change after the two fires, that left only about 8 months of development, production and testing. Seems crazy to me.

Porsche plays on words.
When talking about a brand new engine , it must include a 4 L that is not the Mezger but is derived from the 991 GT3

But it could be plausible:

1. Product planning is done years in advance.
2. Euro 6 deadline was known about years ago.
3. The 991 RS has been doing significant testing for well over a year - it has been spotted testing more times than any RS before it IMO.
