    According to https://en.wikipedia.org/wiki/LaFerrari, the LaFerrari has a peak output of ~800 horsepower. ~160 of them supplied by a KERS system parallel to the ICE.

    But the LaFerrari definitely isn't the only hybrid supercar there is. https://en.wikipedia.org/wiki/McLaren_P1 this page says that the P1 uses a similar system. However, there are also cars like the https://en.wikipedia.org/wiki/Porsche_918_Spyder which (at least in their wikipedia pages) do not mention exactly how the system works.

    So, what I'm here to ask is whether these cars just y'know... cut off power from the electric motors when their batteries run out? I've always imagined them as being on full peak horsepower output every time. But they have to get their energy from somewhere, regenerating electric power from the combustion engine seems unreasonable when you go full-throttle all the time because that would create mechanical energy losses and at that point it would be smarter to send that power directly to the wheels.

    Just have a look at the single-speed (!) koenigsegg. This extreeme use-case illustrates the benefits of these hybrid setups. (namely: bottom-end torque) .

    Re- generative braking system like the F1 cars and modern fork lift trucks to name a few.

    Problem with these systems..current and earlier..went they go bad..they go bad in a really big way. It's great tech when all is working, but it doesn't take much to upset the system

    People buying all these electric and hybrid cars - super cars or not - have no idea of the future maintenance nightmare(s) awaiting them as the cars age and fail. Like you said above there "when it works, it's great" but when things stop working or battery cells start failing, good luck.

    You can keep a Ferrari from the 60's or 80's on the road with a little TLC. But in 20-40 years, I don't think it's going to be the same situation with all the hybrid Ferraris coming down the river.

    Well..from what I have been working with..Ferrari is not supporting the LaFerrari batteries anymore..they are all rebuilt units..at 75k a pop. Apparently a new unit if it can be sourced is 250k. That's a ton of cake no matter your finances. The Kerrs system itself..good luck Chuck.. made to order..

    That sounds like a fun repair bill to explain to your wife.

    To be honest do you think we ought to be getting worried about our 2000 year onwards cars?
    Look at the trouble the Ferrari owner on this forum is going through with his 612 gearbox, seems he cannot find a replacement gearbox ECU for life or money and Ferrari have been poor at helping out too!

    Parts are getting to be a big problem. And it's only getting worse it seems. I can't help but think this is by design. Hopefully the aftermarket will start picking up on it..but not likely unfortunately. Too few cars to justify the development costs. But where there is a will..there is a way.

    This seems to be an overall question for all electric cars… my daily driver is an Audi E-Tron— what happens when and if the main battery dies? Most EV cars have 8 year warranty on the battery but after that? Do all these cars just become throw away. Who is going to spend 30-150k for a new battery at that point? I’m in the car business and have no idea of this answer.
