Yep, the 490 kph Bugatti Chiron Super Sport 300+ has been knocked off the mantle by a Chinese electric car.

I hadn't heard of the BYD Yangwang U9 (surprised?) but it sounds like a lot of car for the money. For less than half the price of a Porsche 911 GT3 (313 kph) you get 960 KW and 391 kph for your 360k.

But then.........They come up with the BYD Yangwang U9 Track Edition.  2,220kw.  That's 2,978 horsepower.  On the same track the Bugatti broke the record on, this thing has just run 496 kph, and the driver only backed off because a crosswind was moving the car to the left. He said it was still accelerating at the time and would have gone past 500!

It's not a one trick pony either. It lapped the Nurburgring only 2.8 seconds slower than the record time. It will only be a matter of time (or finding the right driver) before that is beaten as well.

Quite amazing specs that thing.

 

1200v system, 80kwh battery ( wouldn't last long at full tilt ) into 4 x 555kw motors ( via some drive wizardry obviously).

Charge up to 500kw ( a little  more than an extension lead may be required!!).

 

Just where you  find a 500kw charger, dunno.

Just how long the battery would last at flat out, dunno.

Just how much of a weapon it would be......f%$$$ yeah!

 

Oh, and don't forget the 1972 Aussie Supercar scare where the weapons were going to put out 200 -300hp!!  Had to ban 'em.

DC motors are awesome things. You should have seen the 4MW DC motors on No.2 Bloom Mill main rolls. It’s the batteries that are cr@p. Solve that and internal combustion will be dead inside a few years. Just like steam cars were when internal combustion arrived.

The internal combustion engines quickly took the market from steam engines due to a few downfalls with them. 1) you had to go out and cut up huge amounts of wood or order a truck load of coal. 2) you always needed to be close to a water source for top ups. 3) didn't have a long range before needing to replenish the fuel source. 4) you had to light a fire and keep it burning for at least 2-3 hours to get enough heat into the system before you could drive away. 5) excess smelly smoke and emissions.

 

The last of the steam cars "Stanley Steamer" in the early 50s rectified most of these issues however they still required extra work as a daily driver.

Electric cars still have some of the shortfalls of the old steam engines. You still have to be mindful of your next fuel source, is it within range and the refuel is going to take some time to refill. The coal source is now stored at the power stations. Yes you can refill from a solar system but very hit and miss when your away from home. Like everything mechanically previous they will come up with the answers over time. But if it doesn't happen quickly someone will come up with an alternative propulsion idea before electric cars get a genuine foot hold. Of late there a quite a few new alternatives being developed that could make electric cars redundant or dramatically reduced.

Almost all of the electric car issues come from the batteries and their limitations, not the cars themselves. In the worst case you use DC motors for drive and have an onboard MG set providing electrical power. As I said once the battery problem is solved you will not want an internal combustion vehicle. Solving may mean not even having a battery for motive power, it may be a hydrogen fuel cell, it may be a hydrogen internal combustion gen set with a small regenerative battery like a hybrid. It may be a far superior battery tech like salt or solid state that will hold more charge than your bladder can hold, and can charge in minutes. Or some combination or technology we do not realise yet., but my bet is the drive will be electrical probably DC motors.

Too many governments have thrown everything into the ring with electric cars.  They won't even look at hydrogen now.

They'll be forced to by common sense. Without nuclear or coal or gas we cannot generate enough stable power, or get the power to the homes/industry for any more than maybe 15-25% of Australia to have EV's. Just read the news today, Microsoft and Google are paying to restart shutdown Nuclear Plants in the USA simply to provide reliable energy to their AI technology.

What we will have is a huge daylight excess of solar energy. Whilst Hydrogen is not efficient, if excess daytime power is available it can be converted to Hydrogen AND it can be stored and transported when you need it. That is the problem right now: storage of excess energy, and transmission to get it to where (and when) its needed. Whilst Hydrogen is a b!tch to store and use, it is both storable and transportable. It doesn't have to be stored or transported as pure H2 though, you can enrich natural gas and burn off the Hydrogen. Or it can be stored as a metal hydride. None of it is easy or cheap though.

I read an article six months ago about a company in Canada revisiting compressed air engines with late tech, basically a better rattle gun. The power plant is staged so the exhaust from the first air motor feeds the inlet of the second air motor then to a third motor, each motor has a reduced capacity. The 2nd & 3rd motors obviously produce less power then the first, but there isn't much waisted air by the time the 3rd motor exhausts. The three air motors engine brake on over run or braking for regenerating air back to the air tanks. The torque and hp are very impressive. This idea of the larger motor feeding the next was invented over 135 years ago which operated on steam power. There are bugger all moving parts and can work perfect in poor environmental conditions or even submersed in water. There would also be a reduction of 400kg of weight on the average small car. Doesn't need a cooling system and the car can be air conditioned by the air exhausted. Like a rattle gun which is always cool to hold after a few minutes of operation.

 

The engine has instant power like a BEV, and doesn't require any fancy gearing. Reverse is achieved by redirecting the air through the motors just like a rattle gun. They are as quiet as an electric vehicle and zero emissions. Due to the high torque a high gear for cruising could be added to reduce air flow and usage extending highway miles by up to 40%.     

 

Figures of 650hp & 1,400lb of torque depending on motor sizing. The motor package only weighed in at 40lb and the size of a two-cylinder motor bike engine. The vehicle braking system re generates air back to the air tank reservoir increasing range. Photos in the article had four very light weight air tanks that looked to be the size of your garden variety size G oxy bottle. They were claiming 450-500 miles before exhausting all the air. They claimed the vehicle can be air charged from home and a high pressure compressor would be supplied with the new vehicle. The home charging system can be set to cut in when solar export electricity was diverted to the compressor and cut in and out as required till the storage tank was full. (free air ready to go and download when you get home). The vehicle could then be charged from the home storage tank and fill the car tanks in 10 seconds. Much quicker then any electric car and still quicker then filling the daily with petrol or diesel.

 

The air vehicles would also have an onboard air compressor that would plug into any 10amp outlet and recharge the vehicle with full air in 38 minutes.

The article also stated 0-60mph (100kph) times in a medium size 4 door car in 2,4 seconds. If all is true and the battery EV manufactures don't buy them out and shelve the idea the electric vehicle industry could be made obsolete very quickly. It would be easy to have air storage at local service stations. and its not flammable. They also mentioned that an aftermarket easy adaptable kit for old cars could be supported at one fifth the price of an average EV battery.
