2025/2026 Hybrid Powerunit speculation

Or a 1.1l V4 with a split turbo in the V. Should be easier because it it a shorter block. Than add a 240kw MGU-K

Pulse-jet driven MGU-H turbo with a fully integrated MGU-K in the rear diff.

No battery! Spin em to win em!

isn't that a space heater ?
being as a PU less than 50% efficient

It could be, but the sound of 20 of them at the starting line of the GP would be epic!

Not to mention the downsizing over an ICE, as well as 80kg of weight saving... Plus zero water cooling needed, just oil for the one moving part (turboshaft).

I agree with Horner...

Clearly Wolff are after the money...

For reference, I notice the Porsche 919 Evo only revs to 8000rpm. So I guess that is what F1 would rev to, if the maximum fuel flow was available at any rpm and not from only above 10,500rpm?

If you like the sound, you should rewatch some games from the world cup in South Africa 2010, a pulse jet and a vuvuzela sounds similar ...

Vuvuzela's have turbochargers attached that alter the sound like the pulse-jet MGU-H that I've speculated?



Look at the device at 57 seconds. It is easy to imagine a MGU-H in between a split turbo being a pretty simple addition (other than obtaining one...). Why couldn't a setup like this run as a real-time 3phase electric generator and power a drive motor?

That's not a pulse jet

I'm pretty sure in the earlier build vids he referred to it as a turbocharged pulse jet. Please explain why it would not be?

Because that is a regular turbo jet, with s compressor stage, combustion stage, and turbine.
A pulse jet had no moving parts (I can have a vale though), and uses a shockwave to compress the air, and it does so in pulses, hence the name pulse jet.

Am I right in thinking the V1 flying bomb used a pulse jet?

A pulse jet and the jet in that video sound very different to me.

Correct Marty, that's not a pulse jet, but this is, you can hear it pulsing,
& see how inefficient it is at converting fuel into thrust, rather than heat:

I would welcome a 2 litre v4 like Porsche lmp engine.. Why? Less rpm but more hp and the v4 will like the v6 be a structural part of the car.

Indeed, such an engine type was proposed recently, of course by VAG, although it was not clear if it should be a V4 or a four inline.
Not very likely to be accepted, auto motor und sport though noted that even Ferrari alledgedly has no serious reservations against that type of engine any more.
So with VAG of course wanting a refreshment from the scratch and the others keep the current formula as much as possible, why not accepting both configurations?

A slightly bigger engine v4 means less moving parts than a v6. The mgu h should remain but the other manufacturers has to offer it for sale. Nicd cost cap.. A inline engine need a support frame. Hence a v4 is a better solution

A inline 4 has much less moving parts then a V4 and is a lot easier in construction (with only one exhaust side instead of two), and only needs two simple structures on the side as a support... I don't see your logic.

Why not use the existing inline-four 2.0 from Super Formula, DTM and SuperGT? There are already six engines designed to this formula (Mercedes, Toyota, BMW, Nissan, Honda, Audi) which could have a hybrid system added.
