Concept power units from 2030

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Maybe they'll be allowing beryllium and titanium, and more exotic stuff in all of the engine...

Is beryllium still toxic?

What is currently allowed? Mostly just steel and aluminum? Is any Titanium currently allowed?

With a drastic reduction in the amount of regen braking, the rear brakes will have to get larger/heavier, increasing the loads on the rear suspension and their mounting points. All of which increasing the mass of the car, none of this proposed v8 leads to a lighter car. Team principals have already said they prefer to not return to in race refueling.

If this is what they are planning, it should be a hard pass.

They should keep 1.6l V6 current engines, 2 turbos, and fuel flow to 110kg/hr E80
Agreed on the hard pass on the v8, but a single turbo hot vee is better than twin turbo. They should be allowing the engine manufacturers to invest in future tech like rotary valves and plasma ignition.

I think it is a smart proposal and should end up with something like an 85/15 split and a much lighter, simpler, cheaper engine overall. A 3.0 single turbo V8 running at lambda 1 should be efficient enough to minimize the fuel weight gain and the lower boost pressures should allow for weight savings in the engine block and pistons. This is a good reason to go with more displacement. A 100KW MGUK is small enough to allow a tiny battery and still not lead to the level of starvation that leads to clipping induced position changes that cause the yo yo garbage we have today. I'm sure it will sound better without being obnoxiously loud like the NA engines were. I'd assume 138hp from the MGUK and the 750-800hp from the ICE for a total system output of 900hp. This should be enough to keep the materially lighter cars as fast and as safe while the average power wouldn't be far off the 2014-2025 engines either so drivers can push at will. I hope this is what passes and the FIA should be willing to say goodbye to any manufacturer who wants to add weight and/or complexity to this.
I believe they are aiming for a total of 1200hp peak, which would require a much higher fuel usage. I disagree that the engine block would weigh less even running at lower pressures. The current engine blocks have a minimum mass that the manufacturers could easily lower, but they have decided not to compete in that area.
I'm pretty certain 1200hp won't happen. That would be madness. The cars would have to add so much size and weight in crash structure to stay as safe as they are today. They aim for at least a 10% weight reduction. That would imply a peak power of ~900hp to avoid that disaster. The average power would still be much, much higher than the current cars and they would minimize the fuel weight gain.

1200hp is one figure I have seen mentioned, also 1000hp.

1. Why deal with the turbo lag which comes with a single turbo? Can be easily be sorted out with a twin

2. If the single turbo is out of the gearbox, the car wheelbase can be mandated to be 3000 mm, natural reduction of weight with a shorter car.

So? They banned it to hinder Mercedes, the rest were excuses. As a material of the engine it wasn't toxic to anyone. Unlike some special fuels in the past.

Most parts seem to be Al or Fe based alloys or only Fe based alloys.
