Why none of them has V12 since Mclaren F1?

>>28534061 (OP)
Because America has figured out the best way to make reliable bulk power. Koenigsegg's engines are based on the Ford Modular V8 and both SSC and Hennessey use some flavor of the LS platform.

Even newest V16 bugatti is hybrid

you need turbos to hit over 280 mph in a supercar because it has to haul around a luxury interior and crash safety features. i would speculate that packaging a TT V8 is easier and cheaper, and that's the main reason. you could do it with a V6, but the turborcharging is going to be wild and V6s are hard to sell unless your name is Ferrari.

this, its easier to just rely on the decades of collective R&D america has already done than try and make a new V12 or higher number of cylinders from scratch.

Bugatti is a giant VAG stunt that no other manufacturer has the money to replicate. cars were much less powerful when the F1 was built.

It's easier to find a boost-hungry V8 than V12 for ultimate power. Koenigsegg developed theirs from Ford, I'm sure both SSC and Hennessey now use LS based billet blocks from companies that normally supply drag racers because they're plentiful, relatively cheap and a known quantity. Only huge OEMs like VW can afford to develop a new platform like a W16 turbo dildo rocket.

>Koenigsegg's engines are based on the Ford Modular V8
no lmao
they were a bit at the very very start, but their current engine is a completely different design

>>28534061 (OP)
Koenigsegg's V8 has its lineage from Ford's Modular V8 that got haphazardly thrown in after they failed to acquire Subaru's flat-12 F1 engine. Then Koenigsegg said "fuck, that's a good fucking engine, we're going to fucking keep it", and the rest is histrory.
Hennessey is a tuner who made bank on turbo-ing all kinds of american engines, he knows first-hand which one of them is the best, and he picked the LS. You'd think he'd go for the Viper V10, but no, apparently LS is just better.
SSC doesn't actually exist, it's an elaborate hoax, so they just pretend they have some kind of V8 knowing full well that everyone will default to "oh, that's just an LS, I guess that works", instead of raising questions by saiyng it's any other engine config.

>>28534201
It is a ship of Theseus, they've changed everything at this point but it's still a deep evolution of the Modular.

>billet blocks
No, those hacks ain't using anything even remotely close to a billet block.
I don't even think they are using the stronger DART LS blocks either.

Friction

>>28534464
they are billets. its the only way they can handle the power they're making reliably. they talk about the engines in detail, look it up.

>>28534061 (OP)
Mostly the size, increased cooling, and production costs. A V12 would need a decent displacement to make this kind of power, which would make it very huge. A standard V12 is already larger than a V8 and a V10 engine by default, but when you start adding multiple turbos, the intercoolers, all the extra cooling not needed in a V8, it starts to pig out quickly and not fit in anything besides a truck.

V12s are a massive casual filter. You need to be absolutely locked in when you build one.

Cosworth GMA?

>>28534218
Hennessey is also a retarded hack. Emissions is the soul reason why record setting cars all use hybrid V8s. We know from aftermarket that the best option is something with colossal displacement like the Viper V10. Displacement is the master of all performance, but the EPA REEEs if you have too much fun. Nth Moto slaps a couple of turbos, a forged crank, heads, and a fuel map on a Viper and gets 3300hp and absolutely ludicrous speed for a fraction of the cost.

>>28535489
But I don't think 3300 hp is suitable for anything other than drag racing. Engine, tires and rest of the poewertrain aren't indestructible and this power will tear it apart sooner or later, although most likely a 3300 hp V10 will last longer than 3300 V6.

>>28535504
Obviously, it's too much power for anything but straight line speed. However, those heavily built Vipers are running stock blocks at that power level with incredible reliability. There are fuys with lower end packages pushing 1300hp or so that track theirs and the videos of them running road courses are insane.

V12 has too much internal friction, but light rotating mass. Thats why Ford built 6.8 v10 bc same rotating mass as 5.4 w/ 25% more cubic inches. Its a balance.....

>>28534218
>SSC doesn't actually exist, it's an elaborate hoax
Wdym?

>>28534218
If ssc supposedly doesn't exist, then what can be said about a scam like devel sixteen?

>>28535525
Imagine the timeline where John 'hack' Hennessey followed through with the V10 Venom GT like the original concept and it was making 3000hp. Then again he must be using the LS for some reason. I bet trying to package and cool a TT V10 in a mid engined car is a nightmare.

>>28534061 (OP)
2024 and older Lexus LFA had V10 engine.

There’s no point building a V12 when a more simple V8 will do.

E.g.: the Viper’s V10 could be replaced by the shorter Hemi Eagle today at same power and torque levels. Now if you use the leftover space for any kind of boost, the V8 advantage goes though the roof.

V8s have perfect vibration balance, perfect heat distribution, share the plenum, crankshaft and cam shaft between cylinder rows and are incredibly power dense. Even at 50% cylinder deactivation, a V8 is still perfectly balanced.

There’s no better layout for FR cars.

Cross-plane or flat-plane?
