*Singer Announces Engine Collaboration with Williams*

[Won]

Stijn, the air outlets on the lateral side of the car ahead of the front axle have an effect of masking the front wheel wake for reduced drag and lift. I see a very functional looking diffuser, which makes me wonder how they vent the cooling air for the engine. Perhaps it exits through the new openings made between the standard longhood rear bumper and the extension piece. All these details are exactly what we applied on World Rally cars from 2016 and 2017. The roof slot was also proven on WRC cars from a slightly older generation. I suspect it is even more effective at energising the flow over the rear window and reducing lift on this fastback shape. So for me, the whole package looks pretty well optimised for a general GT car shape. But still this car is unmistakably an air cooled 911.

The cross brace on the door could be very structural. It would be easy to design a composite structure there which is as strong as roll cage door bars.

I was priviledged to be able to follow the aero development very closely, fascinating watching the aero performance numbers go up and what change had what affect.

Lots of influences from many different cars have gone into creating the aero shapes. Some more obvious than others.

Is there anywhere I can read about the aero and real tech specs of the drivetrain? I've been trying to figure out the cooling and muffling, and nobody seems to have any info beyond speculation...probably because they don't want anyone to know. It's mostly pretty photos and "500hp".

I wonder how much of the original 964 Porsche BIW is left on this car. Speaking of which, I'm assuming the bodies on these are done at the Grove Williams facility and not shipped from ARIA down in Irvine all the way to England.

Yes, there are smog legal cars putting miles down in Ca. I've put over 500miles test miles on them. It took a hell of an effort but the team did a great job getting it done. It's legit. Last I knew they were doing another CARB program for the 4.0.

Emissions equipment: I won't get into technical details as that info is out there. You can read about their engine option specs on their website
Remember they do 3.6, 3.8 & 4.0 engines.
Cats are used as well.

Most of the cars are driven hard and often by their owners. Unlike the first few cars that didn't get run hard, they do now. Have you seen the Moscow car (AWD) in the Snow driving with the Koenigsegg? They're driven. There are lots of them out and about.

They have some huge projects in the works, not my place to bring them to light here but stay tuned.

I worked there for 3 years. Have over 5k miles driving them.
From car 7 thru 60 something. Senior builder, test driver, Carbon body QC, vehicle dynamics (sound deadening to shake down), production manager etc. It was a fun gig. Tough and challenging but massively rewarding.

Rob is a visionary and has some very cleaver engineers working with him.
I hope they continue to thrive.
The cars aren't for everyone but I appreciate them for what they are.

Hope that helps.

Who's your sound deadening person? Does he drive an old white Mustang? This person I talked to sometime ago moved into my neighborhood (up the street) and claims he worked on the sound stuff for Singer. He came from the air craft industry. I was not driving a Porsche when we met, but he was a little funky to the point of not wanted to talk, not even about his Mustang. Forgotten his name, I have not spoken to him since

[Tremelune]

I would like to speak to this guy, too...

It's all a compromise because they want to preserve the look of the early 911 to some extent(not realy succesful imho)
IF they wanted optimal aero design then it would not look like an early 911 and be more like a 99x of sorts.
or something even more different then that.

[porsche4life]

I don’t love some of the exterior design features, but that interior is exquisite.



The most interesting part of the article for me though was the weight. 2150lbs!!! With 500hp that thing is going to go like a scalded cat! I’m really hoping someone brings one of these to rennsport next year!

I think something like this then:

That guy in the white mustang is Olen, he did the original formula. However, it was insufficient for modern levels of NVH control. I personally did the updated study and the testing on the cars. We are able to drop the db levels as much as 10-15db and in some areas much more. I documented the study on more then 10 of the cars while I was production manager and test/shake down driver. I examined modern GT cars and luxury cars for their manufacturing strengths and weaknesses. Ultimately we retrofitted many of the first 12 cars. The formula followed now based on the testing is lighter by 10+lbs and - 10- 15db. The cars are so quiet and solid even with the large tires, big motor and monoball rears, yet you still can hear and feel the important stuff. It wasn't overly muted.

It's not necessarily secret sauce as much as it is an understanding all of the material choices available, knowing every nook and cranny of the body as well as how and where the panels are bonded.

I'd do a walk around tech talk of a stripped 964/911 chassis to detail if the offer ever came.


PS. The Green car pictured above was "optimized" in England. Nothing done on those at Aria. We shipped them various donor cars that were prepped in different stages. Williams guys spent a lot of time with us in the shop at SoCal understanding what we do for the standard car. Singer has staff in England for several years now.

Oh man, is there anywhere to read that information?? I'm like a child, throwing mass at the problem and it kills me.
