  1. My son has a BYD Shark PHEV. I've been looking at some Australian-made videos on Youtube made by 4WD influencers, and most of what they present is positive. However there are a few things that have got me thinking that the design concept of the vehicle is wrong. First, the vehicle is a 3-tonne dual cab. It is a tall vehicle, meaning that one has to climb up into it. Why so big? It has a Gross Vehicle Mass (GVM) of 3,500 kg and a payload of approximately 790 kg. That 750 kg paylod has to include the weight of five persons plus luggage and other junk. Don't forget that if the vehicle is used to tow a caravan or other type of trailer, the towball weight has to be taken from the 750 kg. I wonder how useful it would be as a tradie's ute. How much do a tradie's tools weigh? And how often do five tradies travel in the one vehicle? Next I don't see it as an off-road vehicle. A lot of the videos show it being used off-raod, but I think this is a mistake. I think people might not understand that although each wheel of the vehicle is driven by its own motor, it does not, to my mind, equate to the traditional 4WD. While each motor delivers maximum torque immediately, off-road driving requires that the torque from an ICE or EV power plant should be controlled. I think that the correct application of an EV motor is through a gearbox if one wants to drive through mud, sand and climb mountains. BYD has been honest in stating that the battery-only range is 100 km. That is sufficient for daily running around the local area. They have been honest to say that for longer distances, the 1.5 litre ICE engine must be used. This engine is basically an onborad electrical generator which uses about 7.5 litres/100 km at highway speed without towing. Towing a medium sized caravan or horse float can blow that out to about 20 litres/100km. One advantage of teh BYD battery system is that it has outlest which can provide 240 volts. That would be useful for a tradie to run chargers for cordless tools. Why do I think the design concept is wrong? Around my way, the most popular style of work vehicle is the Toyota Hillux in single or dual cab. The vehicle weighs about 2 tonnes with a load capacity of about 900 kg. This design suits the needs of farmers and tradies. It is available in 2 or 4WD configuration. Why couldn't a model with an EV power system be made to this design? Toyota has a Hilux EV, but it is a big monster like the Shark.

  2. What I can't understand is why people drive those kinds of vehicle around the suburban area. They take up 1.5 car parking spaces, and anyone in a medium sized sedan parked beside them can't see past them when exiting their parking space.

  3. Siso there's no highly loaded bearings OR rapidly reversing loads etc in an electric Motor. Reciprocating motors are just trying to fling themselves apart and have Large Pressures and thermal stresses. and critical Lubrication issues.. The electric Motor is Near 100% efficient and can also GENERATE electricity to recover power. Nev

  4. This presupposes that we are the only country attempting to cut CO2. Yes, our share is small, but all of the countries that contribute under 2% make cuts adds up to 30% (I am happy to back that figure up) How are these actions abhorrent? When you say you don't accept the science, are you saying that CSIRO is incompetent or part of the malicious conspiracy that you alluded to? I approach climate science like any other area. I have had people tell me that vaccination doesn't work or causes autism, etc. I reject this because I can see what CSIRO says. Being extra cautious, I can cross-check this with other respected sources. This seems to me to be a solid method of determining what the likely "truth" is. If you believe this is a flawed method, then suggest a better method. If the outliers in climate science are right, then why not the outliers in medical science or any other field? Vaccine sceptics also tend to cite "grand conspiracies."

  5. When you run a diesel out it of fuel it will get air in the system will have to be Bled properly. Sometimes even changing a fuel filter has to be done by a competent person with the right equipment. Contaminated Fuel with water can cost thousands of dollars. None of this with EV's No turbos , No EGR Valves. No air cleaners No Mufflers to rot out. No need to warm the engine or watch it on a hot day. No starter Motor, gearbox or clutch to wear. Reduced Brake wear. Servicing reduced to tyres and windscreen wiper Blades. No fumes No tuning. . Dramatic revolutionary change. Nev

  6. Well this will help them turn the ship around... 😂 ABC Live blog says Tony Abbott is positioning himself to be the next president of the Liberal party. Kind of like hiring Putin to be a conflict mediator, or Trump to bring honesty back to politics. https://www.abc.net.au/news/2026-05-07/federal-politics-live-blog-early-childcare-commission/106651090
