Ok, now this is very interesting.

Those who've watched the vid with Tuthill and Harris driving like, and I quote, "utter bellends" in the insane Tuthill 911K, will appreciate Tuthill's rather unhinged approach to building visceral drivers' cars.

I'm curious if this GT ONE also requires a donor car and if that donor car must be a 911 GT1 - I can't see how that's the case in reality - or if this is a bespoke, ground-up build.

Irrespective, this thing is going to be MEN. TAL.
 
Any word if it's based on a or many 911 components or is the chassis/platform completely bespoke? It says fully CF-bodied with CF-paneling underneath? Methinks it uses a 992 platform for this just based on the size of this thing. Definitely a head-turner.

I hope the latter. I hate the idea of taking something original and mongrel-ing them, no matter how good the end is.

It has to be using a 993 main structure. That's the way the original GT1 did it, to avoid having to crash test a new bespoke chassis.

This car is such a good idea, you wonder how come these other restomodders didn't think of it before. It seems everyone keeps faffing about with 964s that mimic 60s-70s motorsport looks, that only boomers feel sentimental about. Meanwhile homologation specials from 90s and early 2000s is what younger petrolheads actually dream about.
The original cars are pure unobtanium and probably somewhat underdeveloped compared to serious projects like Carrera GT. Not to mention they are way too expensive to use properly. And unlike the existing GT1 replicas, built in a shed, this will be a properly engineered and sorted out car. It's the most excellent choice of a project from Tuthill!

The only thing it's missing at the moment is the wing.
Now, if only RUF could somehow snap out of it and start making desirable cars again...

I think Ruf are ahead of the game, they have there own modern proprietary chassis, they build there own engines. They also have the CTR3 which isn’t a restomod.

The fact they are capable of making their own carbon tubs and engines is why I hold them to a higher standard. They could be doing so much more than 80s 911 retro design with awkward LWB proportions.
Fair play to them if the new CTR and SCR are in demand. It's just not very ambitions, that's all.

Let's be honest, CTR3 Evo is just a dressed up 2008 design using a 997 crash structure (hopefully with some mechanical updates). I liked it when it was new, but now it's an outdated meta.

As far as I can recall, the 911 GT1 had more in common with the 962, than with 993 or 996 (later GT1s used the fried egg of the 996; and the 98 Le Mans winner was completely different)

I'm not sure where you're getting LWB proportions from, a 964 has a wheelbase of 2270mm, the Ruf SCR is 2272mm, height and width are also within 1-2mm of each other, the SCR is a little longer 4291mm vs 4250mm.

Yeah, that's fair to say. GT1 is this very strange mix of 993 front clip (converted to double wishbone setup) and steel monocoque with tubular frame on top.

From engine to the back it's very similar to 962. It's also fully water cooled. The only major difference is the intercoolers sitting on top of the engine instead of hanging on the sides. That's why it has that massive roof scoop.

I think you might have the wrong SCR there. The new one is totally different:
"Ruf has lengthened the wheelbase by 70mm by pushing the front axle forward by 50mm and the rear back by 20mm without extending the overall length."
 

That article has it wrong as well, the SCR and CTR are built on a carbon tub with pushrod suspension. the article you linked says it's based on a 993 body in white.
Technical highlights?
The visual differences between the SCR and a 964 are positively subtle compared to what’s going on beneath the surface. Firstly, it's based on a 993 body-in-white and utilises the later car's multilink suspension. To improve dynamics and stability even further, Ruf has lengthened the wheelbase by 70mm by pushing the front axle forward by 50mm and the rear back by 20mm without extending the overall length. This stretched wheelbase is so artfully disguised that, if no one told you, you'd have little idea that anything was different.
