If the displacement isn’t measured in cubic meters, can you even call it an engine?

I’d opt for the V10 from the F2004 Ferrari F1 car if I had to pick an engine to listen to, it’s what a race car should sound like. There’s just something about a V10, it sounds musical.

That BRM V16 is a close second though! It’s probably more impressive given it’s 50 years older than the Ferrari engine and was not designed by computers.

Then all you need is a good recording and decent headphones

Ok, me too now. But you can’t have that, so maybe you could settle for a high-reving V8 in a tunnel?

Why do you need an axle?

Put the engine and its transmission to the wheel mounted next to each wheel.

No need for differentials etc, if they can work out a steering mechanism for each, then you've got 4WD with 4W steering.

In the video there's talk of how you can use them as regenerative braking as well, so have that as part of the wheel structure.

No axles, no differentials, independent suspension, electronically controlled power to each wheel, regenerative braking.

Gonna be a fun decade or more of innovation coming.

One in every wheel
