Adrian Newey has confirmed that they will use pneumatic valve springs:

We started out with the twin-turbo V8 twin because we needed around 1000 horsepower from the combustion engine, and the only way to get that with our target engine weight [of 150kg] was with a turbo. Then we started working with our own powertrain division to look at how we can get the power out of a normally aspirated engine? The answer was rpm, but how do we achieve a high rpm? That meant going to pneumatic valves instead of valve springs. We’re continuing to do durability work to get a normally aspirated V10 that weighs 150kg, revs to 15,000rpm and has 1000hp.

By the way, the Mercedes-AMG One has pneumatic valve springs too and that's a road car. Compared to F1, they have added a pneumatic pump.

The problem is keeping the seals lubricated and “wet” while the car sits.

Sure you can do it if it’s exclusively in the care of Mercedes or RedBull (Cosworth), where they’re going to tear into before you schedule it to run, but the issue is 20-30 years from now when you can’t find those bespoke seals anymore, the manufacturers aren’t interested in supporting these, and they sit a lot between runnings. This is why people are converting engines like the Cosworth EC and ED engines to coil springs.

As pointed out, you can’t even turn these engines over until you know all the valves are retracted, and require PITA leak tests constantly.

That said, most of these aren’t even going to run but a few times, so it it’ll be fine.

Any dimensions of car?
How tunnel reduce so much pressure if it is so high from ground, you can sleep under car?

[Fluido]

Factually incorrect. It has a very very similar size and footprint to an Aston Martin DBX. So a wheelbase of at least 5m is about 1.5m out.


DBX has a 3060mm wheelbase and a Length of 5039mm and a Width of 1998 mm.

A bit of careful listening to the video at 12mins 30seconds will clear your inaccuracies up

Why they made in bigger version for presentation?

The design has changed quite a lot since the first concept model, but now it looks like an actual car, still has a lot of resemblance to the Valkyrie

The similarity is like comparing two F1 cars from 2025.

It's a bit embarrassing it has turned into a Valkyrie v2

If it ain't broke... Although it looks quite a bit moved on from the Valkyrie. The rear suspension is exposed, on Valkyrie it was not. Snorkel louvers (bet you've never said that before), either linked to chimneys or they bleed overflow, in which case: clever. For the side radiators it looks like: louvers and three cannon exits (hmm, where have I seen that before...). Rear brake duct inlet integrated into the flying buttress. Seven-element rear aero stack. Bargeboards connected to the FW. Shrouded brake discs. Overall, alien, UFO-like. Looks good in silver.

They want people to use it in ACO Hypercars potentially, so the approach makes sense. It has to stick with some conventions. Regardless, nothing in that series has this much aero sophistication.

What will Newey cook up with Aston Martin, though? Beside AMR cars. Further iterations of the extant Valkyrie LMH. New hypercars. New track specific cars.

I don't know how they expect it to corner at 5G. It's downforce to weight doesn't seem like it's good enough
