2026 Hybrid Powerunits

A lot of extra friction and inertia for how much benefit?

Also, the crankshaft is a 3 pin, 120° crankshaft by the rules. How well does that work with running a 4 cylinder?


4 cylinder running a 4/6 of maximum fuel flow = 2,100MJ/h, which is 6,802rpm per fuel flow regulations.
4 cylinders running at 550MJ/h = 2,200MJ/h, which is 7,155rpm per fuel flow regulations.

Yeah turning 2 cylinders completely off and carrying the dead weight of those cylinders doesn't make sense to me. I could forsee a scenario where decreasing feul pressure in 2 or 3 cylinders loses less HP than using that xtra pressure in the remaining cylinders gains.

Electric CVTs are more reliable than any other transmission type.
They are being adopted in the US and Japan. Almost all Toyotas use them.

Yes but they can only be used with hybrids.

A battery is not required for an eCVT to work. It just needs to send power from one MG to another MG to perform the transmission function.
The battery just allows regen braking and more power for acceleration.

It definitely would be a better Idea for future regs than a V8. It would be illegal in the current rrgs. You need 1 MGU-K connected to the Sun Gear and another connected Ring Gear. So it would be heavier? Also is it patent protected by Toyota? I seem to remember thr original patent from 1997 expired but there a ton of micro patents.

haven't 20000000 or so been made ? (Toyota, emulators under licence of T's patents, and others)

Not really a CVT though, is it.

Absolutely unnecessary!!!

They should have lived with 6MJ limit of recharge and 150kw deployment 160kw boost and returned to pure racing of 750hp

With that they should have concentrated on reducing weight.

how is it not a CVT ?
if (as chipengineer has said) it can adjust the gear according to energy moving only from one MG to the other

it has 'geared neutral'
(the belt CVT hasn't)

ok the (DAF-style not Volvo-style) belt CVT was its own differential, though
