Wonder what the cooling will be like on the Founders edition
Trucks look good though, specially if the numbers are true.
Had to stretch myself a bit to buy a Tesla Model S!
Would love one of these new Roadsters but definitely way out of my budget :(
Hopefully they get the cooling right and you could use it as a track car, otherwise it would be an expensive car for day to day use!
Tesla just went full-Knight Rider.... :O_o1:Quote:
Tesla\'s new Roadster caused a bit of a surprise as, with a touch of theatre, it drove out of the back of the Tesla Semi trailer ...
I'm afraid not, Michael.Quote:

Tesla just goes whiper-whisper... :lol:
whisper whisper, but they're having a lot of trouble making the Model 3.
But... NEW CARS!
...in a straight line. With that massive range, it isn't going to be light and I couldn't find a weight for it.Quote:
Tesla's new Roadster is "the quickest car in the world"
The biggest gain in the truck is probably the aerodynamics. I think I remember reading a few years' ago about someone petitioning the EU to change the current regulations on truck sizes to allow them to be more aerodynamic and the savings it would make.
I appreciate the sentiment of them trying to distract investors/shareholders from their current production problems (the BBC's article does bring that up: http://www.bbc.co.uk/news/technology-42021713), but I doubt not developing new products would address the issue, and it makes sense from a company's point of view to keep designers etc. busy with something else.Quote:

with the rise in electricity. ill stick with a biodiesal dodge ram 1500. their is always some fast food place trying to cut cost of cooking oil disposal.
I couldn't find any confirmation about the energy density of the 2170 as there doesn't appear to be a reliable source for their capacity of 5.75Ah. Whatever it is now, I don't think it will improve as it is already in production for the 3 and there is no doubt quite the lead time to test and design these. Add in all the extra ancilliaries and 625kg would be a minimum for a 200kWh battery. For a sports car I would have thought having the "normal" range of 300miles and making it lighter would be better, but I guess the extra range is actually a side-effect of needing more cells to provide the extra power.Quote:

coefficient of drag (cd) is a nice brochure number et all but cda (coefficient of drag x front area) is the real number that matters and I think the truck might just loose on that one.
The chiron also has a very poor cd by modern standards, mainly because it's designed not to take off at 270mph...
Most modern bog standard cars are under 0.3, aerodynamic things like the prius and other tesla's are under 0.25, do wonder what that new roadster is!
That truck will need a portion of the trailer to store its batteries.... 80% charge in 30mins sounds impressive though depends on how many kw's that is. Shame though that it has a range of a car and not a truck and wont be able to last a typical truck drivers shift without re-charging which is a big no-no when on the clock
A couple more prototypes and they could remake the Italian Job (again):DQuote:
