    An internet rant I missed :(

    Tyre and brake pad wear produces nearly 1000 times the carbon particulates that exhausts do, and is unregulated. EVs have big ass 20" chromies, weigh a hundreds of kilos more than efficient vehicles that sip on the waste products of dead dinosaurs. 

    We need to ban overweight vehicles, like EVs and shitty SUVs, and those running too large a tyres on the back of hatchbacks, to save the planet. Stop start is as irrelevant as taxing chicken farts.

    https://www.emissionsanalytics.com/news/pollution-tyre-wear-worse-exhaust-emissions#:~:text=Using a popular family hatchback,a factor of over 1%2C000.

    A Tesla model 3 weighs near enough to a 3 series, and lighter than an xdrive 6 cyl car, most EVs aren't really much heavier than their ICE counterparts 

    All new cars are flabby ghastly rubbish

    That is an excellent bit of reading though

    Ironically we won a Holden Barina 1.4 a few years back. Drove it to work for a couple of weeks while waiting on m3 parts . Got 6.3 L/ 100 km. Yet the cx5 with a 2.2d does 6.5 L /100 km.  A lot can be said for high torque low rpm running. But suspect c02 between the two would be a large difference.

    CO2 = fuel burned. The old 33kw barina should have always been put in the bin, hateful things

    not disagreeing with you at all but devils advocate  I guess you times your savings by every other car on the road say in the EU and it all starts to add up personally I think better tech designed around shutting off cylinders would work and mean we could still have powerful cars for when the occasion was wanted, v8s that idled along like a honda jazz around town but still opened up when planted.

    Cylinder deactivation is working towards this. I have a 15 year old V8 that has deactivation

    And an 87 year old car that does it all by itself on accident

    If I was interested enough I would want to see the original test data and methodology used. That guy is just a youtuber who makes a living out of presenting basic science to uncritical audiences. He did not make the actual tests. 

    For example, every time the starter cranks the engine it draws energy from the battery. That energy is restored by the alternator putting extra load on the engine, and that requires extra fuel to be burned. Was this factored into the original test data ? Small four cylinder engines can be expected to be more fuel efficient that larger 6 or 8-cylinder engines. How would this affect the results ?

    Until proven otherwise, youtube videos are not worth the paper they are written on :) 

    Cheers...

    The load from the alternator is not really an issue. 

    It's reasonably easy to figure out having an engine turn of for a certain period of time leads to small fuel savings

    That's an appalling summary which ignores the cost and the vastly different scale. Political will isn't the issue here, it's physics.

    1000kV DC link is what ya want, China are doing obscenely long transmission. Some big boy PV stuff going in Aus also. The infrastructure is mental, the synchronous condensers on those big projects are upwards of 250 tons. One we SourceSafe an armature that weighed 180t and needed a road built to get it to site 🤦‍♂️

     

    We need more localised production, not just for EV but for future proofing NZ. Heatpumps are as big of an issue, same problems with inverters making yucky stuff happen on the grid 

    And we need to boot the old boys club that is the NZ generation and transmission companies, govt has little to do with it and frankly they would struggle to do a worse management job

    Yup it is an absolute nightmare at the moment.  Some of our competitors in the electronics hardware game are getting out of hardware full stop at the moment.  Sourcing and shipping parts is a massive problem.  Shipping is getting more expensive every week yet is less reliable.

    Yup. Bringing gear from Russia is a bit spendy now too. But, who needs power stations to work?


  7. The rack stopping is done when the inner tie rod hits the casting in the rack, so no it's not worn 

    If it's lowered, has wider tyres (not by much either), different offset wheels, worn bushes or a bad alignment it will do it. Most e36s have some wear there. I have turned up lock limiters for drift cars with modified knuckles, but typically they don't rub hard enough to cause issue

     

    Edit, they typically hit the left more than the right 


  8. You can pick up ring grinders pretty cheap, but it's a pretty boring task and not exactly a tool you will use often. Mine spends more time being on loan than in my toolbox 🤦‍♂️ in a pinch you can use a diamond file or points file. 

    They will need the block to do them
