Electric Vehicles this week

https://insideevs.com/news/406403/video-tesla-model-3-responds-traffic-lights/

Kyle Conner (Out of Spec Motoring), the head of our new InsideEVs YouTube channel had a very unique experience today. He was able to ride in a Tesla Model 3 that has the update that allows it to "see" and respond to traffic lights. It's one of the updates that Tesla shared will be coming as part of Full Self-Driving Capability soon.
Unfortunately, we can't reveal at this time how he was able to get access to the car, but he took several photos, as well as a few videos, of the feature in action. We also can't yet reveal if this is early release or an "early adopter" vehicle or if other Tesla owners are already beginning to get access to the new feature.
Apparently, the feature also stops for stop signs. In addition, it lets you know that it has "seen" the light and will be responding so you don't have to wait and wonder

This is huge. It's been one of the major things the Tesla can't do. Very close to full autonomous driving. Be interesting to follow the week to see how it pan's out and more importantly how well it works.. :purple

Tesla starting selling their new car the Model Y on Black Friday 13... This is the first car that they have released ahead of schedule. It shares 70% parts of the Model 3 and is a SUV crossover (whatever that definition is) . Many think this will be the companies real breakout car as SUV's are much more popular than Sedans... Tesla also made it's 1,000,000 car last week, this also was the New Model Y... :purple
Have Tesla only made 1 Million cars?
Yup but made 370,000 last year , 500,000 this year, they made 2000 cars 8 years ago, to see how far they have come... :purple

They are doing well and won that “competition” as well.
Yeh, great video: I note the Tesla only did 78% of its claimed range however. But that was the point of the whole video :bike :yak yak

They had to put headlights on and used a/c so the Tesla was pretty close to its claimed range (measured during the day w/o a/c etc :bgrin )

The official ranges are government tests the car makers have to adhere too, just like the internal combustion car these are for perfect conditions and rarely if ever do they match up in the real world...
The range numbers are not manufacturer estimates...

For electric cars the USA government (EPA) one is the most realistic on range and lowest if you want to know how far one can go... :purple

Now VW dump hydrogen as a fuel source, Just not efficient enough...

"The conclusion is clear: in the case of the passenger car, everything speaks in favor of the battery and practically nothing speaks in favor of hydrogen. “No sustainable economy can afford to use twice the amount of renewable energy to drive with fuel cell passenger cars rather than battery-powered vehicles,” says study leader Dietmar Voggenreiter. This is also the view of customers: In Germany there are already more than 130,000 battery cars on the road – but only 507 hydrogen cars..."

poor jules…. :purple

Anyway, here are some more hydrogen disadvantages that the industry does not like to talk about:
1) Hydrogen from methane (most common source) results in upstream CO2 emissions of 5.5 kg CO2 per kg of hydrogen just from the chemical reaction
2) It takes at least 14 times as many hydrogen delivery trucks to deliver the same amount of fuel (range) as a gasoline tanker.
3) A typical hydrogen dispensing station (130 kg) can only dispense enough hydrogen for 24 FCEVs. And this dispenser stations costs $300K USD to add to an existing gas station
4) Filling up a series of FCEVS in succession (3 or 4) results in the dispensing tank losing pressure and heating up to the point that a 10 to 20 minute pause is required for repressurization and cooling otherwise the vehicle gets half or less a tank. (Hydrogen heats up when it expands into a vehicle fuel tank)
5) Most gas stations do not have the room to accomodate any serious number of hydrogen dispensers. A small 130 kg dispenser requires the equivalent of about 4 parking spaces and would fill only 24 FCEVs per day. All H2 tanks must be above ground so new stations with large footprints are required for any serious dispensing requirement and are very costly.
6) Producing hydrogen and dispensing on-site could only be done in sparsely populated areas (for safety reasons) which underscores the article's point about extensive travel time to and from refueling points vs charging at home
7) Check out the used FCEV prices. Used FCEVs are available in California for just $13 K after less than 3 years - an 80% depreciation loss in less than 3 years. It FCEVs were desirable, the depreciation rate would be 20-30%.

Hydrogen at least when used in a fuel cell is pretty well hopeless.... :purple

It did win so yeh: go Tesla :bike My point is that market theory relies on full information so this is all relevant if true!

Why, then, are they never underestimated? :jump :jump :jump :jump :jump

Actually there is a lot on controversy in the USA about the official range of the new Porsche and how it's about 80-100 km's under what everyone is getting... so they can be underestimated
I guess a bigger question is why car manufactures don't also publish realistic ranges and efficiencies to let their customers know what they are buying and to stop[ disappointment... :bike

Elon Musk
Apr 1

We have extra FDA-approved ventilators. Will ship to hospitals worldwide within Tesla delivery regions. Device & shipping cost are free. Only requirement is that the vents are needed immediately for patients, not stored in a warehouse. Please me or
@Tesla
know.

Wow this man is amazing, look at GM (may they rot in hell) they promised ventilators, then they said not till the end of this month, then they said they could only make one tenth of original promise and wanted more money than all the others, then Trump had to actually order them to make some.... :purple

And giving them away for free, only proviso they are going to be used straight away!

Great marketing for Tesla, true, but still amazing!

Nitrogen Oxide levels in Barcelona have fallen a staggering 83%, the majority of which has been attributed to an unprecedented drop in road traffic. More irrefutable evidence that ICE’s are the problem. Imagine the world we’d live in if we all drove electric cars? :purple

Tesla has officially become the world’s most valuable automaker, surpassing Toyota Motor Corporation on Wednesday morning. However, Tesla is much more than an automaker, and its success has a lot to do with its other sustainable projects.


Tesla now holds an over $185 billion market capitalization, meaning the total value of all of the automaker’s shares of stock is worth more than any other carmaker on Earth. Toyota now sits in second place, with its $178 billion market cap.

Not bad really for a company that is supposed to be broke....
the next big announcement will be soon with new battery tech... they will be releasing a battery that will do 1.6 million KM's, or for a home power supply last at least 20 years, about double the time a battery lasts now....

That will make batteries more affordable (lifecycle costs) even if the new batteries are more expensive to buy.

What's the price point to buy electric cars vs petrol driven for consumers? I think i would budget maybe 30K ,,, so its hard for me to pick an electric car at 50% or more higher price.
