OT: Brakes seizing on electric cars? (2024 Update)

[Colonel Edmund J. Burke]

Lockup crotch?

[Dave Plowman (News)]

That would explain it using up spare D type bits.

[The Natural Philosopher]

The jaguar D type had no indicators at all. Front headlights tail lights and stop lights

[Commander Kinsey]

Is that really necessary? I've driven plenty old cars and the brakes are always good enough to be able to lock the wheels.

[Commander Kinsey]

FFS, I tried to drive off today and the throttle jammed fully open. Much WD40 and it's behaving a little better.

Luckily it has a rev limiter, although quite why it jumps about and doesn't stay at precisely the red line nobody knows.

[Commander Kinsey]

No hazard lights in case of a crash?

[Xeno]

Way before that concept appeared on the scene.

[Commander Kinsey]

That's what happens when automation tries to help without having enough information. It was trying to be helpful but made things worse. Imagine trying to drive with one person operating the wheel, one the pedals, one the handbrake and indicators.

The answer to all that paragraph is.... French electrics.

[Commander Kinsey]

Doesn't bother me as I never use any type of handbrake. Park in gear and turn the wheels against the kerb. Hill start using the footbrake.

[Commander Kinsey]

He didn't say that. He said he didn't use the brakes. He might press the brake pedal, but on an electric car that should engage regen before the actual brakes. Real brakes are only used if you press hard on the pedal.

You can apparently adjust what it does when you let go of the gas. But unless the designer is monumentally stupid, no matter what your setting is, braking means regen THEN brake pads. No point in using pads when you could be charging the battery.

Because diesel engines were (for a long time) perceived as slow, noisy and dirty, mainly due to early truck engines. Also perceived as only being suitable for larger engines which is why when they did come to cars it started in the big Mercs.

[The Natural Philosopher]

Smallest Diesel I have seen is 0.3 cc:-)

And of course the real technology that helped make diesels work effectively was turbocharging ...

[Ahem A Rivet's Shot]

Indeed, especially when combined with inter-cooling.

[Commander Kinsey]

But all that went away quite a while ago.

[Commander Kinsey]

Indeed, My Golf TDI was just as good as a GTI.

[Ahem A Rivet's Shot]

Yep and as that got noticed more and more cars got diesel engines, and then manufacturers got caught fixing the emissions tests and it all got smelly again.

[Commander Kinsey]

Not many more. Didn't people notice the hugely higher miles per gallon? I actually heard people saying "but diesel costs more". Yeah, a few pence more, but you go twice as far.

One manufacturer did, and nobody gives a f*ck about treehugging emissions. I look at the miles per gallon only.

[Xeno]

Wait until your diesel engine blows up. Then you'll notice where the higher costs are.

The people getting cancer from the carcinogenic diesel emissions certainly do. Those carcinogenic emissions are why diesel is biting the dust in Europe - regardless of the improved mileage per gallon.

[Commander Kinsey]

Ok, I accept the first one, but seriously, they can't get all the power from going downhill? How inefficient.

[soup]

Of course they can't get all the power from going downhill .

Even a 100% efficient system does not recover all used energy, as elevation change is not the only use of energy. There is also resistance to movement caused by air pressure effects, etc.
