All of which it beats, as per my post. Slight exaggeration, but surely you can see the advantages of this car?

Someone with $200k to spend on a car isnt necessarily buying fleets of yachts and helicopters (those guys are spending $3m on a Chiron). It's actually on the low end of supercar prices these days.

I can see it appealing to the person with 200k and wanting a very fast electric car. I'm not sure that's a big group of people and 200K is a lot to put into a depreciating asset.

I'm also not sure how many people would buy this after driving an exotic petrol super car regardless if the Tesla could beat it to 100Mph.

Right, so we've agreed this is a low volume car, as intended by Tesla.
 
Trucks indeed are limited to 52-56mph over here at least, the variance between the limiter speed and the speed limit is to allow a little leeway on downhill sections where a loaded HGV will naturally exceed its limited speed - you have to keep it in check, if you don’t you soon find yourself going way faster than you want to!
Normally your looking at 0-50mph acceleration in anywhere between 45seconds to a minute at full weight (44tons) with a 450-500bhp engine and a lot quicker if your unladen - when unladen you can easily out drag small cars and vans at the “traffic light Grand Prix” if you floor it with the right gear selection (block changing, starting in say 4th, changing to 6th & so on) but clearly HGV’s aren’t built for accelerating fast and doing so hammers the fuel consumption and puts unnecessary strain on the driveline.

I’m interested to see this from Tesla but given they are struggling to meet demand for their cars at the present I doubt they are going to make significant inroads in the haulage industry just yet, operators will wait until the technology is proven and reliable.

I’m sceptical about the claim of 500mile range @40ton payload (current European hgv’s have a payload of ballpark 28-30 ton depending on configuration) and just why HGV acceleration is a big deal to them I don’t know, all well and good getting 40+ tons upto speed quickly but stopping it again is a whole different ballgame - brake technologies haven’t yet caught up with that kind of performance at that kind of weight, believe me a 44ton HGV needs a lot of braking power to stop it, especially repeatedly where brake fade is a huge issue.

Electric trucks are the future undoubtedly and I’ve no doubt they will take over from diesel, I doubt we’ll see it for a fair few years yet though.

Personally I’d have far more confidence if somebody like Scania, Mercedes or Volvo was developing this HGV technology rather than a company that frankly has neither the experience or expertise in this field which is very different from cars.

Fortunately the other manufacturers have this in hand as well.

The braking power should be considered in a different way from a diesel truck, as it uses regen braking rather than brake discs and pads. The brake cost savings are significant as well.

The acceleration makes a good headline, but in reality would make some difference to overall drive times. However, the acceleration is almost a by-product of the power from the drivetrain that is required to pull the weight.

Also dont forget that 10 years ago Tesla had almost no experience in building cars. While they've still got some way to go on mass production, no-one has come so far so quickly.

With the enhanced autopilot and 4 independent motors, Elon Musk is basically saying these aren't going to jackknife.

That's a bold claim.

10 years in car building isn't going to convince the big operations managers of buying a fleet. It's a very hard fought industry.

I'm not sure regenerative braking would be enough. 30 tons of swinging beef, road barrels and liquids take a lot of stopping.

That wasnt my point.

Regardless, the maths will be the key decision point - if they can save 20 or 30% they will have no choice.
 
We're on a Computer forum talking about the latest gadget in the car world. I guarantee that nearly everyone would get one if they had the money.

In fact, when I make my millions I will get one. Remember this day. Quote this post for I shall return with this Tesla thingy!
 
Exactly, I loathe anything that isn't naturally aspirated, but if I had the £££, a Tesla driveway of each model would definitely be done :D

People seem to have gotten lost in the price and 0-60 times and are arguing over those two mainly. This thing does over 600 miles on one charge, that's pretty radical if you ask me, and that battery technology will no doubt filter down to the "lesser" model range as well.
