Yes. Energy is not free. Anything at all in or on the car that requires electricity gets it from the alternator, or from the battery which is replenished by the alternator. Any load whatsoever on the alternator is in turn a load on the engine.

Is it a huge hit? No. But it is a hit.

It's a load on the electrical system. The serpentine belt, rotating mass, etc are a load on the engine...using the turn signals isn't a hit on fuel economy. Besides, I never use the wipers...I just "plan ahead" and avoid those rain clouds.

You're being facetious... Right?

It's a bailout joke around here, based on his theory about dodging. If he can avoid accidents by dodging deer that spring onto the road by planning ahead for it, I can dodge the raindrops.

I guess we have a 1stToyota joke now, too. Something about free energy and perpetual motion serpentine belts on the Yaris.

Are we pretending that belt driven accessories don't rob hp but using the turn signals and washers do?

Guess the sale of underdrive pulleys will be down now and Toyota will go back to belt driven power steering pumps and cooling fans... and they'll switch back to 6v systems so they'll take a lot less hits on the MPG

And energy isn't free...takes a voltage generator (alternator) and a reference source (battery), and of course a regulator/PCM to adjust for electrical loads. Thinking that using the radio will cause worse fuel economy is drastic and silly. And the reason the A/C uses more fuel is because it takes more force to operate the compressor with the a/c clutch engaged, vs a free-wheeling bearing, has nothing to do with current load on the alternator.
