Tesla stock opinion Videos

+TheDavoFloresChannel, PAY ATTENTION: I have NOT this pickup. I didn't record the audio! It's NOT my bass! This sample isn't made by me. This pickup is very good to me and the youtuber Mark Spitz played with Squier, SD and this Tesla Precision pickup and others, and like this. I really think buy one, but it's the same price of SD SPB-1 and I bought the SPB-1 and the Seymour Duncan is the classic vintage sound and very nice!!

Nope.

+Paul Hendrix One follow up report showed a Toyota that was impaled through the underside. it almost killed the driver.

+m1aws if it was a gas car, the driver would have died from the steel part's impact before the car would have exploded.

+Ham T So if a truck tow bar punctures your fuel tank, will you walk away from that? Will the people behind you come out unscathed too?

+Chuck O Cooling is a good point you make. At theoretical top speeds such as 200mph there would be a large amount of heat in a body designed to slip through air without ducts feeding components air to cool off like in sports cars. If this car can go 200mph it would be for a short amount of time. However I would love to see someone try. Eliminating speed limiter, bypassing any safety programs in the car that reduces power when there is excess heat, it would be interesting to see if it can be done.

Electric cars can have gears but its largely unnecessary considering their extremely flat torque curve.  For all "normal" operating speeds (0-120mph), there simply is no need or advantage to having gears. This of course allows EV's to have lighter simpler drive trains. For older Direct Current motors there was a slight advantage to having a low gear just to assist with take off after which a taller "Drive" gear would be chosen for all other driving. This was done to make the car a little more efficient since electric motors will draw huge amounts of current as the motor just begins to spin up. With a low 1st gear the DC motor would spin up more quickly (drawing considerably less current), against the heavy initial load that a vehicle presents when its not yet moving.  This isn't as much of an issue with modern poly-phase inductively coupled AC motors (such as those used in a Tesla). There is something else you need to consider when talking about increasing Tesla's upper speed limit: that is that these inductively coupled AC motors, while very efficient, will begin to produce some heat (as will the controllers when handling extremely high amperage). Wide open these motors will quickly become quite hot. Since Tesla did not design these cars to be top end racing machines they have no provisions for dealing with the sort of heat associated with top end racing. They have a rudimentary cooling system that is more than adequate for the driving envelope they were designed for. Rather than accept the increased expense and weight of a beefed up cooling system Tesla chose to use a simple circuit to shut down or place the car in a low power mode if you try to run it wide open for very long. Just as you wouldn't put an expensive upgraded NASCAR cooling system in a gasoline car that was only intended to drive between 0-120mph, Tesla felt it was not needed for their target audience.        

Yes but you can't really rely on one gear to take you from 0-200mph. The reason electric cars have one gear is because they have high amounts of instant torque that doesn't require different gears to get it up to speed. But when taking it up to 200mph one gear may not be enough purely due to centrifugal force :)

The tesla has only 1 gear... It's an electric car...

I was thinking the exact same thing with the amount of torque being delivered due to the added traction on all four wheels. So much more power can be added so much sooner getting much better drag times than what it is already getting. I saw an article that says theoretically the P85D can do well over 205 mph. Accounting for the power it has (691WheelHP) and the low coefficient of drag of 0.24. Compared to the Charger Hellcat that has 707 CRANK horsepower ( about 10%-15% loss in power once they get to the wheels) and a drag coefficient of 0.35 yet can do 204mph than the Tesla should out due it, but now its just a matter of gear ratio and unlocking speed limiter.

Good catch Adrian, the Tesla has a very sophisticated AWD traction control system that would increase the torque if larger stickier tires were installed. Remember, the tires Tesla uses were chosen more for their low rolling resistance than how sticky they are. Because of Tesla's weight I suspect the rubber is also very hard to maximize tire life. Realizing that if larger stickier tires were to be used they would be put at all four corners of the Tesla which would allow the traction control system to deliver a lot more torque to the pavement. Consider also that Elon has already alluded to the software upgrade that's coming which should bring the Tesla P85D's 0-60 times down to 2.8 seconds. This is just the beginning for whats coming by way of electric propulsion. The existing motors are more than powerful enough to beat the Hellcat as they are not being driven at their limit yet. Tesla's performance is limited more by its software governor which is set to protect the expensive battery pack. As the batteries become lighter, more energy dense and capable of dumping higher amperage without overheating expect software tweeks to take advantage of it. Top speed however, won't improve unless Tesla decides to give the car an overdrive of some sort. Presently it doesn't have a transmission but rather a simple reduction gear differential. With the tremendous amount of torque that motor is capable of and the ability to spin at nearly 14,000 rpm, an overdrive gear would give the vehicle a lot more top end. Hellcat owners can breath a sigh of relief as Tesla is unlikely to do this since the car was neither designed nor meant to be raced top end. Remember also that presently Tesla uses tires that are limited to a 149-mph top speed. I suspect that they'll have to be upgraded when Tesla bumps the top speed to 155 mph.

Look at the first two shifts the brake lights come on traction wasn't completely disabled if that didn't happen I think he could have been in the 10's

You're* :)

+colin garder So are you. It's you're not your :)

And your a terrible speller

+dobbins2550   The Tesla's acceleration and top end speed are software limited to protect the expensive battery pack, and lengthen its life. Non the less, it is a fast car for what it is.

+dobbins2550  It may have zero traction issues but that doesn't mean its traction control computer is putting full power into the launch. The computer is monitoring traction and reducing the torque to keep the those (non drag slicks), tires from spinning. The Tesla's traction control computer would also increase the power to the pavement with better rubber just as the Hellcat did.  You're a fool if you think those electric motors wouldn't be capable of putting out a lot more torque into better rubber.  They've already shown where the P85D motors were capable of being over driven, putting out 30% more torque than has been advertised. 

Tesla is AWD, zero traction issues.  Hellcat on DRs will crush the Tesla and it should.  This 11.1 is .5 second quicker and 10+MPH faster.
