BMW: All Models Electric Within Decade

And with it, a better vehicle too - the simplicity of getting good NVH is orders of magnitude greater than an ICE. And the chances of getting mechanical issues also tend towards zero as there just aren't any where near the loaded components to fail. And the performance potential! 1000BHP will be a very easy goal for an EV supercar...sports car even.

Nail on the head. Not to mention how easy they are to drive on today's increasingly congested roads.

er, a 1st gen Prius minimum of 12 years old now! How many pre 2003 ICE Nissans are still working and not requiring new components?? (in fact, a lot will have simply been scrapped as "worthless")

They were introduced here in 2000, 3 years after launch in Japan. Oldest are closer to 15 years old in the UK (I know that's what you were saying).

A typical 4 cyl ICE has around 40 to 50Nm of friction at idle.

A typical synchronous PM Emachine has around 0.1Nm of friction at "idle"


Here's an easy test. Accelerate you car to 60mph. Leave it in gear, lift off accelerator, note how car deccelerates. Now repeat in neutral. You'll be able to feel a MASSIVE difference!!

(ok there are some pumping losses involved as well, but the point stands)

I'm not disputing your figures, I assume you know for sure given your background. It sounds an awful lot at idle though, I'd be surprised if it's that much when turned off.

Again, I'm no expert, but from experience of hand turning an engine without spark plugs in, I would expect the pumping losses to contribute more to the engine 'drag' than friction. However, I will bow to your greater knowledge.
