Roadster Tesla Roadster 2.0

Pretty much. The 3/Y will be the battle equivalent of BEVs. Churn out as many as possible, cheaper and faster.

I wouldn’t be surprised if the Semi is also cancelled or remains at Beta stage for another 3 years.

That would be a huge blow to the Company's credibility.

Agreed. If Tesla does not deliver the roadster or Cybertruck, their next concept cars will be perceived as a joke.

However, the financial markets might not care as long as production and delivery figures for the model 3/y keep growing.

What a pity, then we will never know if Tesla remembered to put decent brakes on a sportscar…

The semi was never a particle idea, a long haul truck needs to be able to run 24/7 with only stops to change drivers and refuel, not an operating pattern a BEV truck is going to be capable off for many years to come.

Not to mention that the batteries required for the truck would seriously hamper its carrying capacity as there are weight limits on trucks (at least in the US).

Not exactly. The Semi uses the same motors as the model 3/Y and they weigh about 40 kg each. The drivetrain saves about 2t, which is equal to a Tesla battery of about 400 kWh. So it should weigh almost the same as a diesel semitruck and thus having the same towing capacity within the legal limits.

from what I understood the semi has an 8000lbs battery pack for a 400 mile range. How is that going to be suitable for long haul?

Why should be suitable for long hauls? Most haulers don't cover more than 400 miles per working day. So there is a huge market for EV trucks covering 200-300 miles per day.

When I worked for a courier company our line haul trucks ran 24/7, for example a truck would do Auckland Waiouru, meet the Wellington Waiouru truck, the drivers would swap, the trucks would carry on to the destination. Unload, refuel and head back. Auckland Wellington is 640km.

One of our drivers moved to Australia with his wife, they bought a truck, both drove and switched when they timed out. You can’t operate a BEV truck like this. Hydrogen is the future of trucking IMO.

Energy consumption for that thing is supposed to be at less than 2 kWh per mile(According to Tesla.com). That would mean that the Semi truck could have a usable battery pack of up to 1000 kWh for the 500 mile version.

A single Model S has a 100 kWh battery pack and starts around 95000$ in the US, while the Semi truck with a 500 mile range was to begin at 180000$. 10 times the batteries need to be used for a product that costs 2 times more lol.

Imagine how long it will take to charge the 1000kWh batteries to 80% capacity. Probably quite a few hours. I have a friend who has a freight moving company and he used to tell me some of his trucks run 16hrs a day when hauling important long distance loads. So if the trucks do 80km/h cruising speed they would travel about 1100km to 1200km in one day trip. An electric truck doing only 650km on 1000kWh battery pack wouldn't be the ideal vehicle for his fleet if it has to stop half way and then spend a few hours charging the batteries.

From 0 to 80% it will take about 35 min. The trucks will have their special chargers, which are more powerful. More cells means it can take more power. The time for charging depends on the power factor of the single cell. More batteries means that it is like charging 6 Teslas on 6 chargers instead of one. The time needed to charge these 6 Teslas is the same like the time to charge a single one. So these trucks will be able to charge 300 miles in about half an hour, which is the normal time for a rest for a lunch or a dump. Drivers are also humans and they also need to stop during these 16 hours of working.

There I've to agree! At least in central europe/germany, I rarely see two truckdrivers on one truck, so that they can swap drivers if max. allowed driving time per driver has reached ... opposed to that I see an armada of trucks parked at truck stations/petrol stations around the highways, where drivers are pausing to fulfill the legislative pause times ... so this would be an occasion to recharge anyhow? Only question: What charging infrastructure would be needed, when there are around 40-50 trucks approaching in a small timeframe, which is normal at the typical truckstopps ....

 

[bmwz4coupe]

The problem with electric cars is the same for trucks and normal cars; not only is the range terrible, but they need a lot of time to charge up the batteries.

The charging per truck will be higher than 1 mW. So to charge 50 trucks simultaneously at least 50 mW (app 60 000 kVA) are needed, which would bring the need for a whole substation (the produced electricity is increased to 110-400 kV in order to be easily transported, than the voltage is decreased to 10-20 kV by substations (for local use up to 20-30 km distance and than additionally reduced by a transformer from 10-20 kV to 400 V (for distances of up to 3-5 km) (all currents are three phase). For such a big power on a remote place the supply should be taken most probably from the high voltage grid and reduced accordingly.
But for a couple of trucks no such issue is present.

Nobody knows anything until it arrives, if it arrives that is, I'll give you that.

But I heard exactly the same said about the Aston Martin Valkyrie.

Valkyrie is a limited production hypercar .

And by obsolete , I would say that the tech is odd. Because it was claiming 2 sec for 0-100. That's what the Plaid does right now , with half the battery.

I think Plaid put the real hold on Roadster.
