Still to see if it can do it over and over again like the sports cars it's billed to compete against.

Re: Tesla Roadster
#192I would really love to know how they are getting such a large battery capacity in a vehicle of this size. Is this a generational leap in energy density? What kind of materials are being used here?
I read elsewhere it has 6800 18650 li ion cells. I haven't fact-checked that yet, mind you.
This explains their battery supplier "problems". Those ebay sellers want you to buy a flashlight with each one of those batteries. It all makes sense now. /s
Re: Tesla Roadster
#193Those acceleration figures are meaningless. The Chiron isn't the best car on a circuit for example. I would be interested to see this car compete against say a gt3 on a track like Nürburgring :)
Circuit performance is meaningless. I'd like to see the gt3 accelerate to 100km/h under 2" for example :)
Re: Tesla Roadster
#194The Tesla roadster specs are insane! No exotic carmaker will be able to match it (taking price as a consideration). (no Ferrari, or Lambo, can get that close. This is Formula 1 acceleration speeds). Plus 620 miles of range, and it is a 4 seater. Expensive as hell, but this is exotic car territory. Base Specs Acceleration 0-60 mph1.9 sec Acceleration 0-100 mph4.2 sec Acceleration 1/4 mile8.8 sec Top SpeedOver 250 mph…
acceleration rates. acceleration speeds is like, kinda sort grammatically incorrect.
It's grammatically correct, but conceptually incorrect (sorry, it's always fun to correct a correction :)

Drag racing is meaningless? I totally get that you might not personally like it, but meaningless?

#196Earlier quoted context omitted.
As a Tesla Model S owner, you really don't need to fill your car in minutes. It's a totally different (but not bad) mindset. Every morning my car is full, because I plug it in in my garage. So if I don't go more than 260 miles that day, it's plugged in the next night. It doesn't matter that it takes a few hours. My gas car was just sitting in the garage each night anyway doing nothing. How many hours does your car si…
I've never had a private garage, much less a locked one I could rewire. If Tesla wants to go mainstream they need to handle apartment parking.
My apartment offers EV charging parking spaces, though they cost a bit more than the others. I don't think this is a terribly new or radical concept.
Re: Tesla Roadster
#197Would ludicrous mode for the roadster go 0-60 in 1 second? the 620 mile range is super impressive. How??? Or is it just that the roadster is super light?
You'd think that the ability for the wheels to deliver power to the ground has to be the limiting factor at some point.
Most sports cars are at that point at low speeds and either need a skillful foot or an electronic system to prevent burning out. A 1.9 second 0-60 is pretty much the limit on street tires (and requires AWD). Someone will take it even further by putting drag slicks on there.
Re: Tesla Roadster
#198Bold prediction: if they manage to produce a battery capable of 620 mile range promised, it will essentially be game over for ICE cars. My bet is that next generation of Model S and X will easily be in the 400-500 mile rsnge.
It's cost at that point. For a 25mpg car you can buy 200k miles for 8000 gallons, which is much cheaper than whatever the battery cost will be.

That's some unreal level of acceleration. Never seen anything like it.
Something that really impressed me is how smoothly the Model S launches in the Wet, see here: https://youtu.be/iyXSJAICaBc?t=210 [Real Time @ 3m30s] https://www.youtube.com/watch?v=JNzLTW_l2q0 [Slow Motion] Elon talked during some event how the latency / response time of the torque control in the Tesla drive-train is ridiculous compared to gasoline and for that reason even RWD models should handle well in the snow. T…
I'd be pretty nervous running something RWD with massive torque and power on ice. I'm sure it's better to have a more predicateble delivery, but with ice 7 months per year I'm staying clear of high power RWD cars...
Re: Tesla Roadster
#200I'm thinking what this means to gas car makers. Wave 1: "It's all about legacy and prestige, not speed/acceleration". Wave 2: "The track handling isn't all that good, how can drivers take that corner at full power without losing traction". Wave 3: "Alright, we will go electric too".
If this thing has torque vectoring and does a 9 second 1/4 mile, it's going to drop at wave 2. But wave 3 is already here - a lot of smaller companies are talking about making their own electric vehicles. If batteries become commodities, it's going to reduce the R&D cost of making a road legal car by an order of magnitude. We're just waiting on the batteries.
I wonder if GM (or Tesla) will sell crate batteries the way they sell crate engines? Everyone will be drooling over the next big battery they release the way motor heads drool over crate engines. They'll need a reasonably standard size/configuration to be successful, and they could sell the motor, power management and PCM to go with it.
